Prefetch capability for single or multi processor

Hi all
I wonder SAM supports prefetch functionality for single or multi processors.
I need that for research topic.

Well you have it installed, have a look at their site, and see if you find it usefull otherwise uninstall it.
I don't know it either. (After uninstalling) unplug your router and restart your computer, check for update's > Apple menu>software update.
When your devices are up and running select Safari and a window will appear, choose Network Diagnosis to set up a your wireless connection.

Multi-threads will run better on multi-Processores environment?

Are there any proof to say that Multi-threads will run better on multi-Processores environment?
Will Java run better on multi-Processores environment? Are there any proof?
Thank in advance

Are there any proof?The proof is in the pudding, so to speak. The best thing to do is to benchmark your application on single and multi-processor machines.
It should be noted that there are reports of threading problems with Java on multi-processor machines. I haven't seen the problems myself, nor do I remember the exact problems people were seeing (and on what OS/Hardware) but if you search these forums you should be able to find out the details.

Multi-Processor Systems vs Single Processor systems

In general, is it better to run Weblogic on a fast single processor system
or on a multi-processor system where the individual cpus are less powerful?
I am assuming that the platforms are WINTEL and all other things (memory,
disk channels etc) are equal.
What are the licensing implications of one philosophy over the other?

your client load.
I'd suggest that you run a load test against both systems and compare
the results.

Upgrading from single processor to multi processor

I am looking for information on upgrading a 7.3 Oracle from a
single processor to a multi processor. I will be putting in
another processor in my server and would like to know how to get
Oracle to use this second processor. I know that I need to
upgrade Windows NT to multiprocessor first but what do I need to
do after that with Oracle.

I'm not certain why that would be the wrong boards. I guess HP has the wrong boards posted on their product's support site at the link below.

Nic, for me the iTunes window looks like this, when I connect my iPad 3:
I select the iPad in the "devices" section of the Sidebar (use: "View > Show Sidebar" if the sidebar is hidden).
Click the "Apps" tab in the "Devices" pane.
Scroll all the way down in the Devices pane to "File Sharing" "Apps" section.
Then do I click "GarageBand" to select the documents in the right panel.
Which part is different for you? Perhaps you could post a screenshot?

Media Encoder not multi-processor capable?

I checked the preferences. Don't see any options to enable
multi-processors. Jobs take forever but they could be going a lot
quicker if they used the full potential of the hardware.
Media Encoder CS4 Version 4.0.0.374
Load average is 1.12
CPU idle is at 85%
The jobs are not being distributed at all.

Here is a shot of my Machine running a 2 hour encode on Media Encoder, notice that one processor is completely maxed out while the other one is completely idle...

Oracle on dual-/multi- processor server

I have a question regarding Oracle on dual (or multi) processor servers. I have purchased 2 copies of the standard edition. I installed it on the server with 2 processors.
My question is whether or not there is something different in the installation for multi processors.
Another question would be if it is possible to install the database on a dual processor, if you only have a single copy of the license.

The licenses are acquired by CPU or by users and you acquired the license for only 1 processor you must not install it on a server with 2 processors. Your enterprise can have legal problems if that situation occurs.

Concurrency in Swing, Multi-processor system

I have two questions:
1. This is a classic situation where I am looking for a definitive answer on: I've read about the single-thread rule/EDT, SwingWorker, and the use of invokeLater()/invokeAndWait(). The system I am designing will have multiple Swing windows (JInternalFrames) that do fairly complex GUI work. No direct interaction is needed between the windows which greatly simplifies things. Some windows are horrendously complex, and I simply want to ensure that one slow window doesn't bog the rest of the UIs. I'm not entirely clear on what exactly I should be threading: the entire JInternalFrame itself should be runnable? The expensive operation within the JInternalFrame? A good example of this is a complex paint() method: in this case I've heard of spawning a thread to render to a back-buffer of sorts, then blitting the whole thing when ready. In short, what's the cleanest approach here to ensure that one rogue window doesn't block others? I apologize if this is something addressed over and over but most examples seem to point to the classic case of "the expensive DB operation" within a Swing app.
2. Short and sweet: any way to have Swing take advantage of multi-processor systems, say, a system with 6 processors available to it? If you have one Swing process that spawns 10 threads, that's still just one process and the OS probably wouldn't be smart enough to distribute the threads across processors, I'm guessing. Any input on this would be helpful. Thank you!

(1) You need to use a profiler. This is the first step in any sort of optimization. The profiler does two important things: First, it tells you where are the real bottlenecks (which is usually not what you expect), and eliminates any doubt as to a certain section of code being 'slow' or 'fast'. Second, the profilter lets you compare results before and after. That way, you can check that your code changes actually increased performance, and by exactly how much.
(2) Generally speaking, if there are 10 threads and 10 CPU's, then each thread runs concurrently on a different CPU.
As per (1), the suggestion to use double buffering is the likely best way to go. When you think about what it takes to draw an image, 90% of it can be done in a worker thread. The geometry, creating Shapes, drawing then onto a graphics object, transformations and filters, all that can be done offline. Only copying the buffered image onscreen is the 10% that needs to happen in the EDT thread. But again, use a profiler first.

IPC on multi-processor environment

I have written a C program which uses IPC resource "message queue" and "shared memory" on a single processor SUN Sparc workstation (with
Solaris 2.5.1 OS).
I would like to know whether my program can function correctly if it runs on a multi-processor SUN platform (e.g. Sun HPC model 450 with more than 1 CPU installed).
Does anyone have any experience on this?
Best Regards,
Annie

Hi.
The IPC features will work find in an MP environment. It is designed for processes which are normally protected from each other to be able to exchange data. You just have make sure that access to your message queue or especially shared memory is synchronised between multiple processes by using semaphores (see semget(2)).
You could also look at using just one process but multithreading it.
The multithreaded programming guide covers the issues.
Have you expereienced a particular problem?

Multi-processor Multi-Threaded deadlock

Hi all-
I've posted this over at jGuru.com and haven't come up with an effective solution but I wanted to try here before I reported this as a bug. This deals with kicking off many threads at once (such as might happen when requests are coming in over a socket).
I'm looking for a way to find out when all of my threads have finished processing. I have several different implementations that work on a single processor machine:
inst is an array of 1000+ threads. The type of inst is a class that extends threads (and thus implements the runable interface).
for (i = 0;i<Count;i++)
inst[ i ].start()
for (i = 0;i<Count;i++)
inst[ i ].join();
however this never terminates on a multiprocessor machine. I've also tried an isAlive loop instead of join that waits until all threads have terminated until it goes on. Again, this works on the single processor but not the multi-processor machine. Additionally someone suggested a solution with a third "counter" class that is synchronized and decremented in each thread as processing finishes, then a notifyAll is called. The main thread is waiting after it starts all the threads, wakes up to check if the count is zero, and if it's not it goes back to sleep. Again this will work on the single processor but not the multi-processor.
The thread itself ends up doing a JNI call which in turn calls another DLL which I just finished making thread safe (this has been tested via C programs). The procedures are mathematically intensive but calculation time is around half a second on a P3 800Mhz.
Any help on this is greatly appreciated. My next step will likely be tearing down the application to exclude the calculating part just to test the JVM behavior. Is there a spec with the JVM behavior on a multi processor machine, I haven't seen one and it's hard to know what to expect from join() (joining across to processors seems like wierd concept), getCurrentThread() (since 2+ threads are running at the same time), etc.

My next step will likely be tearing down the application to
exclude the calculating part just to test the JVM behavior.Sounds like a really good idea.
Is there a spec with the JVM behavior on a multi processor machine, The behaviour of threads is defined in the specs.
You might want to check the bug database also. There are bug fixes for various versions of java.

Multi Processor rendering & editing optimization

Hello,
Got some great info here from my last post! So thanx
So my question is...is it more ideal to use Xeon or multi processor board setups than single CPU chips? My main aim is for rendering or workflow turnaround since in the next couple of months I might land a nice spot in the top five post companies in my sector...god willing.
Therefore I plan to build a completely new system either focused on Multi CPU or buying multi crossfire Open CL rendering GPU cards. I can't find any documentation or recommendations for improved performances in rendering speeds or realtime fx with a Multi CPU board or the NOW added multi Stream or CUDA GPU (SLI or CrossFire) rendering setups.
if anybody could explain any myths or facts as to how Premiere Pro takes advantage of CPUs or GPUs would be a big help. I'm currently using a Quadro 2000 and an i7-990x with 24gb of memory.
thnx

Multi processor Solaris 2.6 and mutex locks

hi,
is anyone aware of any documented issues with Solaris 2.6 running
on dual-SPARC processors (multi-processor environment) where the
programs using "mutex locks" (multi-threaded applications), require
some special handling, in terms of compiling and linking, to some
special libraries.
as far as i remember, in some OS book, maybe Peterson's, it was said
that the mechanism for implementing mutex-locks on multi-processor
systems is to use low-level spin-locks. this brings down performance
on a single-processor system, making the processor doing busy-wait,
but this happens to be the only way of mutex-locking in a multi-processor
system. if this is so, then where is such behaviour documented in case
of Solaris 2.6.
i have had problems with my applications crashing (rathing hanging up)
in a vfork() on such a system, but same application works fine, with
100% reproducability, on a single-processor system.
thanks for any inputs or suggestions and/or information.
regards,
banibrata dutta

I am also facing similar problem. Application which written using Mulit-Threaded using Posix Mutexes. When i run on SINGLE processor manchine, i.e.
SunOS sund4 5.7 Generic_106541-11 sun4u sparc SUNW,Ultra-5_10
It works perfectly.
But when try to run on dual processor machine, i.e.
SunOS sund2 5.7 Generic_106541-11 sun4u sparc SUNW,Ultra-250
It is blocking in the one of mutexes.
Please inform us what is problem. Mr. B. Datta, you comes to know
any channel, please inform me also at [email protected]
Thanx & regards,

JRE with multi-processors

Does anybody know whether JRE 1.3 is able to work well in a multi-processor computer with Unix OS
if so, how to implement this ? which parameters does one have to initilize in the JVM so it would work?
if not, how does it work with JVM 1.4 if at all

Threaded code on a single cpu gets timesliced/swapped by the underlying OS but on a multi-CPU system, you get true
parallel execution for free.
Scott Oaks & Henry Wong have a chapter on this in the O'Reilly Java Threads book.

How do I center a text field when input can be single or multi-line?

I'm creating a form in Adobe Acrobat Pro XI and have almost everything the way I want it. One of my last problems is trying to get a text in a text field centered. The input is sometimes a single line and sometimes multi-line. If I set it up so the multi-line entries are centered, then the single line looks off ... and vice versa. Is there any way to have the text automatically centered in the text field regardless of whether it's single or multi-line?

Unfortunately, there's no way to set up a field so that the text is guaranteed to be vertically centered in both cases. If you set it up so that rich text formatting is enabled, it's possible for a user to vertically center, but it's not something you can preconfigure so that it will remain in effect when the field is cleared. For a user to do this, with the focus set to the field they'd have to display the Properties toolbar (Ctrl+E), click the "More..." > Paragraph > Alignment > Text Middle [button]

Analysis for Office support multi thread?

Does Analysis for Office support multi thread/core? If so, what verison? I tried searching around this site as well as note 1466118 - Hardware & Software requirements for Analysis, edition for MS Office but was unable to find an answer.
I am on an Intel dual cpu with hyper threading turned on so it essentially looks like 4 cores. When I execute an Analysis View, I rarely see the EXCEL.EXE process go above 25% CPU utilization. I have plenty of RAM and hard drive space.

Thanks

I found the following info at:
Excel 2010 Performance: Performance and Limit Improvements
Large Data Sets and 64-bit Excel
The 64-bit version of Excel 2010 is not constrained to 2 GB of RAM like 32-bit applications. Therefore, 64-bit Excel 2010 enables users to create much larger workbooks. 64-bit Windows enables a larger addressable memory capacity, and 64-bit Excel is designed to take advantage of that capacity. For example, users are able to fill more of the grid with data than was possible in previous versions of Excel. As more RAM is added to the computer, Excel uses that additional memory, allows larger and larger workbooks, and scales with the amount of RAM available.
In addition, because 64-bit Excel enables larger data sets, both 32-bit and 64-bit Excel 2010 introduce improvements to common large data set tasks such as entering and filling down data, sorting, filtering, and copying and pasting data. Memory usage is also optimized to be more efficient, in both the 32-bit and 64-bit versions of Excel.
Multi-Core Processing
Additional investments were made to take advantage of multi-core processors and increase performance for routine tasks. Starting in Excel 2010, the following features use multi-core processors: saving a file, opening a file, refreshing a PivotTable (for external data sources, except OLAP and SharePoint), sorting a cell table, sorting a PivotTable, and auto-sizing a column.
For operations that involve reading and loading or writing data, such as opening a file, saving a file or refreshing data, splitting the operation into two processes increases performance speed. The first process gets the data, and the second process loads the data into the appropriate structure in memory or writes the data to a file. In this way, as soon as the first process beings reading a portion of data, the second process can immediately start loading or writing that data, while the first process continues to read the next portion of data. Previously, the first process had to finish reading all the data in a certain section before the second process could load that section of the data into memory or write the data to a file.
