Sun Studio MPI Tracing in OpenMPI?

Hello all,
I recently downloaded an installed Sun Studio 12.1 on a RHEL 5.5 system running OpenMPI. I didn't see anything mentioned on the OpenMPI website or the documentation from Sun that I've looked through so far relating to the MPI tracing flags that need to be issued with the OpenMPI installation.
When I invoke analyzer test1.er/ it says that Warning: no MPI tracing data file in experiment...MPI Timeline and MPI Charts will not be available.
Is there a build flag or configure flag I need to add to the OpenMPI installation to get this option to work? Any advice on getting the MPI tracing to work is appreciated. Also, it may be useful to note that I am trying to analyze a pre-compiled MPP program that I do not have the source to. Thanks.

Ok just tested it with the Hello_C program that comes with OpenMPI.
The test goes ok, there are a few warnings when I open analyzer though. It says basically that there were "too few clock-profile events (##) in experiment # (Processor #) for statistical validity
The MPI Trace and MPI Timeline windows did not come up by default but are up now that I enabled them through the menu again and it seems to work perfectly with the Hello_C program so I will try it with verbose mode on our FEA software to see what is going on specifically.
Update:
When I run in verbose mode I see lines upon lines of VampirTrace:Tracing switched off at call stack level (2) multiple times and then immediately after it VampirTrace: Tracing switched on multiple times. This goes back and for well over a thousand lines interrupted sometimes by output form the FEA software.

Sun Studio 12 Update1 and OpenMP

Hi guys,
I was using the Sun Studio 12 with OpenMP and everything was OK. So I decide to download the update 1 (which is OpenMP 3.0 full compliance), however I am getting linking error.
Below is the message:
Undefined first referenced
symbol in file
__mt_MasterFunction_cxt_ build/Debug/SunStudio_12.1-Solaris-x86/a1.o
I look into my libmtsk.so libraries and I could see that __mt_MasterFunction_cxt_ really does not exist.
So I believe this is a bug on Sun Studio 12 Update 1 that didn't install the last library. Anyway, I am try to find out where to get this library or any patch to it. I did try to get the patch 120754. However the site is pointing that I has no support contract. What is true just because I am a student, and I am just learning things for now...:-)
Hope someone can help me with that..
Thanks and Regards

I cannot download any patch because I do not have any support contract.Last time I tried, Solaris patches were free, at least those related to compiler components.
Byt the way, I rarely install the product myself, but I had an impression that Solaris version comes together
with patches, which are intended to be installed right upon the installation.
I'm sorry for the lost hours of precious time, but that seems to be more like your navigational error,
rather than the intentional attempt from Sun to decieve you.
Believe me or not, we made Sun Studio free because we want developers to use it, not because
we hope to catch you offguard and cut some money.
I should get opensolaris if I want a "linux like license and support"And that is true.
If you do not like the way Solaris patches are managed (and, many think that it is a mess) you might better like Opensolaris.
You also might want to try Linux version, it is as close to Solaris version functionality-wise as possible.
I will just uninstall my sun studio 12 update 1 and go back to the sun studio 12 (where no patches are needed to run the openmp 2.5).Sun Studio 12 got no interface change thus no patches were needed to run OpenMP 2.5 as soon as you have libmtsk.so installed.
Quite contrary, SS12u1 got OpenMP 3.0, which is substantially different to OpenMP 2.5 and that warranted interface change in runtime support
(libmtsk.so).
Trying to create "partial open source" things is not that good. First, it is not open source yet :-), it is just free.
Then, if we would do partial thing (which is not that bad per se, surely depending on how you do it), that would definitely be written in caps all around.
And broken functionality is definitely not the way Sun does its business.

__Fedor.

Openmp Multithread programing in Sun Studio 12

Hello Folks,
My name is Glauber, I'm begging in openmp programming.
I'm doing some tests with Sun Studio 12 and c++ language, then I'd like to run a helloworld.cc code using 4 threads but I get only 1 thread.
I've used "omp_set_num_threads(4)" inside my code but, even so, I don't get more than 1 thread.
Could an openmp expert help me?
Cheers,
Glauber

This should help:
omp_set_dynamic(0);Alternatively you can set OMP_DYNAMIC environment variable to FALSE.
This will command openmp runtime to stop being smart and not adjust user-specified threadnum value.
regards,
__Fedor.

Run Sun Studio 12 (wait, this is Netbeans?):*"sunstudio", the IDE, is based on NetBeans cnd.
run this command in any terminal (I have no idea what the & does):
sunstudio &
The & causes the process to be started in the background (and that's the background in the process sense, not the window manager sense). Otherwise the IDE will start, and as long as it runs, you won't be able to interact with the terminal where you launched the application [unless you do something like hit "ctrl-z", which will suspend the IDE, and then type "bg" to background it].

Hi,
we are currently using SunStudio 12. I have noticed that early access product, SunStudio Express, Feb2008. It seems that new features coming from NetBeans 6.0 have contributed to SunStudio IDE. I prefer to use SunStudio Express IDE. But i have also noticed that sun CC compiler version is also different. Actually it is no surprise, since SunStudio is a complete product composed of compilers, tools and IDE.Now, i am quite doubtful whether we should use SunStudioExpress. That's why i want to learn when official new release for SunStudio will be announced.
Though i have searched internet, i couldn't notice any news about the next official release of Sun Studio( Sun Studio 13 ). When will this early release( SunStudio Express, Feb 2008 ) be released as SunStudio13? What is the release roadmap of SunStudio?

Sun Studio Debugging problem

Hello
I need help configuring the Sun studio debugger to work in fedora 8. The project is loaded from a make file, compiles fine, and runs fine.

I have another problem in debugging an mpi problem in another installation of Sun Studio on Solaris 10 on a Sun machine. The visual debugger is working fine there, however, I need to debug with mpirun
to decide the number of processors, because by default it loads the application on one processor. Iwill need to do this as well later on the linux machine I am using now, which doesn't even start the debugger on a sequential code so far.
I appreciate your help a lot.
Thank you very much in advance.

Thank you for your reply. you said 2 problems,Yes, basically I meant these two:
1. dbx: warning: unknown location expression code (0xe0)
2. dbx: panic: "ThreadAgent::setup_helper"(): Assertion (ta_td_agent) failed - "thread.cc":2674
First one should be fixed in dbx itself, but the second looks like an incompatibility between Fedora's libc and dbx; unless distros in "supported" list upgrade to the same version of libc, dbx can't be changed to match it.
In other words, I'm sorry to say that you will probably not succeed in using dbx on Fedora 8 for the time being.

Sun Studio 11- Now Available (and FREE)

Howdy,
Today, Sun announced the availability of Sun Studio 11, the latest release of our venerable set of optimizing compilers and tools. We are very excited about this release for many reasons, including:
* Record-setting optimizing C,C++,Fortran compilers
App performance =� Platform + OS + Compilers/Tools
Using the latest SPARC/x64/x86-systems and Solaris/OpenSolaris versions is great. But to get maximum performance for your app, you need to upgrade to Sun Studio 11.
http://www.sun.com/software/products/studio/benchmarks.xml
* Exploits multicore (CMT) systems for maximum throughput performance
- Multicore optimizations (UltraSPARC, x64)
- OpenMP 2.5 support with autoscoping across all compilers
- Support for OpenMP/Solaris/Posix threads in debugger & performance analyzer
- Dataspace profiling provides hardware and program views into the performance costs associated with application memory references
* Providing Platform Choice: Solaris 8,9,10 (SPARC, x64, x86) and RHEL 4/SLES 9
- Optimizing compilers with Solaris versions only
- Linux version has debugger, performance analyzer, IDE, etc.
- Technology preview of Linux compilers:
http://developer.sun.com/sunstudio/linux
* FREE, unrestricted license (no gotchas)
Sun Studio has been a good and growing business for Sun, but our intent is very transparent with this pricing model change- we want to accelerate the adoption of Solaris and Sun Studio.
Download Sun Studio 11 today:

PS. See what these 2 guys think of Sun Studio 11:
(apologies to those who are unable to view real streams)
http://webcast-east.sun.com/ramgen/archives/VIP-2199/VIP-2199_01_300.rm

In reading the click-thru license, I came across the following in section 5(i):
"Software may contain programs that perform automated collection of system data and/or automated software updating services. System data collected through such programs may be used by Sun, its subcontractors, and its service delivery partners for the purpose of providing you with remote system services and/or improving Sun's software and systems."
Does this mean that the software will phone home to the 'mother ship' and report on my utilization? It seems to be worded in such a way as to be able to send my hardware configuration and other things that I may not want to share with Sun.

Patches for Sun Studio 12 Update 1

Dear all,
I have recently installed Sun Studio 12 Update 1 on an x86 system and have some questions pertaining to the required patches. According to my understanding of the text on the homepage for SS12U1 (http://developers.sun.com/sunstudio/downloads/patches/ss12u1_patches.jsp) it should be possible to download these also without a service contract, but this does not seem to be possible. The SunOS 5.10_x86: Microtasking libraries (libmtsk) patch 120754-6 distributed with the SS12U1 does not seem to be sufficient for 64-bit OpenMP programs. For correct functionality of the compiler patch 120754-7 appears to be needed.
My question thus is if it should be possible to access the required Sun Studio 12 Update 1 patches without a service contract?
Any help regarding this is highly appreciated.

Tthe recent lockdown of all patches by Oracle, making them available only under a support contract, makes the issue of Sun Studio 12.1 patches discussed here quite important. If 120754-07 is required for proper SS12.1 functionality, then users without support contracts must not upgrade their systems to more recent Solaris versions, as SS12.1 will have to be re-installed, and the 07 patch will be unavailable. When will SS12.2 or SS13 (?) be released? If Oracle really wants to make some money, they will never release any further SS updates, thus requiring customers to buy contracts to get the darn patch.
Check these prices for SS support contracts:

$1,015.00
Sun Studio 12 Update 1 Premium Sun Software Service Plan 1-year

Installing Sun Studio 12 on Ubuntu 8.04

When I try to install Sun Studio 12 with the graphical installer, I get a message half was through that Java is not installed. In my case Sun's Java was already installed. I tell the Sun Studio installer to do the update and it finished what it was doing. After the install is done, I found that the Sun Studio executable is missing, so it looked like the installation did not work. What version of Java is Sun Studio expecting and does it need to be tied to a specific path? Is there a known method for installing Java for Sun Studio 12?
After this I uninstalled Java and Netbeans and started the system prep tool, which correctly said I was missing netbeans and java. I had the system prep tool install netbeans successfully but I get this message when trying to install java:
error: Failed dependencies:
glibc >= 2.1.2-11 is needed by jdk-1.5.0_09-fcs.i586

/bin/sh is needed by jdk-1.5.0_09-fcs.i586
Any suggestions?

I could not find any log files with error information from Express or Sun Studio 12. Any ideas?Not yet :-) Can you try to build and debug a sample project? Does it show the same problem?
I mean one of several sample projects, that are shipped with the Sun Studio IDE.
Start "sunstudio", from main menu: "File->New Project", select Samples->C/C++/Fortran->Welcome
Did you try to run compilers and other tools?
Please, make sure they work. For example, run the following commands:
cc -V
CC -V
f90 -V
collect -V
dbx -V
dmake -v
(Note: the last one is small "v")

General and specific questions on the applicability of Sun Studio 11

Hi. In an e-mail letter from Sun Microsystems I read about Sun Studio 11 to "utilize its record-setting parallelizing compilers." From this message I was attracted by the possibility of adding something like parallel processing, not by changing the processor (hardware), but by adding Sun-Studio-11 software to a Linux operating system. Now I already have a Fortran compiler, the Intel Fortran Compiler for Linux, which is free and can handle Cray-style pointers, a feature hard to find in a free Fortran compiler.
1a. So for the most basic of questions, without having parallel-processing hardware, just an ordinary processor [a 1-GigaHertz (GHz) Advanced MicroDevices Duron central processing unit, in my case], is it possible to have parallel processing and thereby increase one's computing speed by installing Sun Studio 11 in a Linux operating system?
1b. If so, by what factor could one expect the speed of computation to increase over not having Sun Studio 11 installed? (If the gain in speed is dependent on the type of computations being performed, I imagine possibly using a Fortran code to perform numerical calculations using and perhaps searching for minima or maxima in a two-or-more-dimensional surface. So please give me an idea of the sort of gain in speed one could expect for these two types of activites, calculations using formulas and searches for minima and maxima among already-computed quantities.)
1c. Again if so, how could one just by adding software have parallel processing without two or more hardware processors? In other words, what is the basic working principle of the software to make the simultaneous performance of multiple tasks (multitasking or parallel processing) possible?
2a. Does Sun Studio 11 include a Fortan compiler?
2b. If so, must one use it to have parallel processing with Sun Studio 11?
2c. Or will the Intel Fortran Compiler for Linux work with Sun Studio 11 to have a parallel processing capability?
Concerning hardware requirements I read that Sun Studio 11 requires a minimum of 512 MegaBytes (MB) of memory, presumably Random Access Memory (RAM). My Hewlett-Packard, ZE1110, Pavilion, notebook computer has 256 MB of RAM, but is expandable to a maximum of 512 MB of RAM. So in this respect it is in principle at least technically possible for me to meet the minimum system requirement for Sun Studio 11 with my computer, if I choose to increase its RAM. Somehow accommodating the cost of such a RAM addition, including whether one may have to buy two, matching, 256-MB RAM modules or just presumably one additional 256-RAM module, is another requirement. But before spending money for such an upgrade, one should first thoroughly investigate other matters to determine if other things are going to work and to determine what gain, if any, one could expect in computing speed with Sun Studio 11 and an additional 256 MB of RAM; then decide, based on such data, whether the purchase is personally worth the money or not. That's one motivation behind this posting; another motivation is for me to learn some things.
Lastly I would like to here thank whoever was thoughtful enough to provide the Sun Download Manager (SDM) 2.0, which allows the pausing and resumption of the 207-MB download studio11-lin-x86.tar.bz2 for the Linux version of the Sun Studio 11! Using a slow, dialup, Internet connection like mine having a maximum speed of 28.8 kilobits/second, this makes it possible to download that file over a number of Internet sessions instead of having to have an uninterrupted, 19-or-more-hour Internet session. Besides the invconvenience of tying up one's telephone line for that long a time, it might be even be difficult to have such an uninterrupted Internet session for that long a time. I have at least started such a download using the SDM 2.0 potentially over multiple Internet sessions. Whether or not I carry it out to completion could depend on whether everything looks good with Sun Studio 11 for my particular situation. Thanks in advance for your help.

Thanks for both of your postings here. I'm mostly trying to learn something here.
From Maxim Kartashev: "For example, if one thread (or process, or lwp) frequently performs an I/O operation, then the other thread (process, lwp) can utilize processor resources to perform, say, some computations while first one waits for operation to complete."
I think I might understand what you meant above. I guess lwp in the above context stands for light-weight process. And I think you may be talking about a potential gain in speed with just one, ordinary processor. I guess you meant that one program, or perhaps group of programs, could perform input/output processes at the same time it is performing calculations because different parts of the processor are being used in these two groups of processes. Then on "while first one waits for operation to complete" I guess you meant that if the input/output operations finish before the computations finish, then thread 1 that was performing the input/output operations will have to wait until the current computations ordered by thread 2 are complete before thread 1 can utilize the computational resources for its own computations; i.e., two threads can't use the same computational resources of an ordinary processor at the same time. How is my thinking so far, Maxim, right, partly right, or all wrong?
Now if the above thinking of mine is right, then it appears that one could have some gain in speed doing things like you suggest with just one, ordinary processor. And if so, I imagine that the gain could be a maximum of a factor of two for a program that requires spending as much time in input and output as it does in computation; i.e., keeping both the computational and input/output resources working all of the time without the input/output resources waiting on the computational resources or vice versa. How is my thinking here?
If the above thinking is correct, just for purposes of discussion with just one, ordinary processor, not a dual processor, and a program which does nothing but computations there would be no gain in speed using Sun Studio 11 and a Fortran compiler over not using Sun Studio 11. In other words, to increase the speed of computation one would have to buy a faster computer, buy parallel processing hardware for an existing computer and use parallel-processing software, or somehow figure out how to harness two or more computers to work for you at the same time with instructions from one piece or perhaps set of pieces of code set up for parallel processing using two or more different computers. The latter case would be a computer analogue or "two 'heads' are better than one," not human heads, but computers. How is my thinking here?
Here I am still assuming that it is possible for one processor to be used to do two different kinds things at once. However, I don't see how one Fortran program could instruct two things to be done at once. This is because I have not seriously studied parallel processing, I suppose. That is I am used to a sequential set of instructions that proceed from top to botton down the lines of code; i.e., one instruction or line of code can't be executed until the line of code before it has been completely executed. That is the computing "world" with which I am familiar. So how about someone here teaching me with an example of parallel-processing Fortran code how parallel processing works, explaining what instruction or group of instructions tells the computer to execute input and computational instructions at the same time?
Based on the encouraging information from one or more other people I have been able to use the Intel Fortran for Linux 8.1.024, if I remember correctly, in a computer with a 1-GigaHertz (GHz), Advanced MicroDevices (A.M.D.), Duron Processor. So this is at least one case where it is not essential to have an Intel processor to use the Intel Fortran Compiler for Linux 8.1.024.
Is the Sun Fortran compiler free for personal use? And can it handle Cray-style pointers?

Sun Studio 11 do not parse make output and create link to file?

Hi,
Running Sun Studio 11 and can only get file links in the output window when I run a make command that uses CC -g (debug option). We have integrated other tools into our make system (flexlint, cppUnit..) and even though we make sure that the syntax is exactly the same as the compiler output and matches regular expression under tools->options->building->make settings->error expression, it doesn't work. Why do you have to debug compile to get sun studio to create a file link in the output window? Doesn't sun studio just parse the text from the make command?
example of flexlint output for which no link is created:
"/vobs/project/oss/fm/fm4/fm-fmalib/fmbal/fmaaulib/src/FMA_List.cc", line 440: Error 84: sizeof object is zero or object is undefined'�
example of make debug output for which we do get a link:
"/vobs/project/oss/fm/fm4/fm-fmalib/fmbal/SunOS5.10/inc/FMA_alarm_record.hh", line 1310: Warning (Anachronism):Info "static" is not allowed and is being ignored.

Ola

I'd second Maxim's suggestion: try NetBeans 5.5 with C/C++ Development Pack. The official release of NetBeans C/C++ Development Pack 5.5 has happened a few days ago. You can download it from
http://www.netbeans.info/downloads/all.php?b_id=2284
Some of the changes between the beta3 build and FCS are:
* Significant performance improvements in the code parser resulting in faster results in the Class View and Code Completion
* Programs now run in an external terminal (system dependent) by default. This allows better input control
* Significant performance improvement in the debugging module
* Significant functionality improvement in the debugging module
* New project type "C/C++ Project From Existing Code" which simplifies creating a project from existing code
* Macro support in code completion
* Hyperlink navigation for macro usages and #include directives
* Reformat code
* Code folding
* Code completion
All these features will appear in next Sun Studio release, so you can
consider NetBeans C/C++ Development Pack 5.5 as a preview of new
Sun Studio IDE.
