Sun C++ versus GNU C++ on integer code.

Hello,
I've been always wondering why so much people praise Sun C++ for generating highly optimized code and why I'm never able to get my project working faster when being compiled by Sun C++ in comparison with GNU C++. I'm testing MICO and nbench2 and it looks like Sun C++ generates slower integer code while faster floating point code. Is there any way how to make Sun C++ generate faster integer code? Please see [http://developmentonsolaris.wordpress.com/2010/03/06/sun-c-versus-gnu-c-never-ending-wonder-just-resolved/] for more information.
Thanks,
Karel

Try some of these options, IME they are probably most likely to help:
-fast -xprefetch -xprefetch_level=3 -xprefetch_auto_type=indirect_array_access -xipo=2 -xdepend=yesSome others that could help, depending on your code:
-xunroll
-xpagesize (and all its subtypes)
-xalias_level
You'd need to experiment to find out.
Of interest is that some algorithms run faster with inlining and prefetching disabled. Algorithms that are extremely register-intensive can sometimes run faster with no inlining or prefetching because both those optimizations increase the use of registers for any source code. FFTW is one of these - it can run 30 or 40% faster with inlining and prefetching disabled.

How does sun cc support GNU C?

I fail to build theora on solaris_x86, it seems some it does not support GNU C style.
$cc -V
cc: Sun C 5.8 Patch 121016-02 2006/03/31
usage: cc [ options] files. Use 'cc -flags' for details
How can I deal with this situation,
- Waiting for new complier
- Write patch for theora(Do not know how to, any idea?)
Sample code are:
static const __attribute__ ((aligned(8),used)) ogg_int64_t V128 = 0x0080008000800080LL;
__asm__ __volatile__ (
" .balign 16 \n\t"
" pxor %%mm7, %%mm7 \n\t"
".rept 8 \n\t"
" movq (%0), %%mm0 \n\t" /* mm0 = FiltPtr */
" movq (%1), %%mm1 \n\t" /* mm1 = ReconPtr */
" movq %%mm0, %%mm2 \n\t" /* dup to prepare for up conversion */
" movq %%mm1, %%mm3 \n\t" /* dup to prepare for up conversion */
/* convert from UINT8 to INT16 */
" punpcklbw %%mm7, %%mm0 \n\t" /* mm0 = INT16(FiltPtr) */
" punpcklbw %%mm7, %%mm1 \n\t" /* mm1 = INT16(ReconPtr) */

" psubw %%mm3, %%mm2 \n\t" /* mm2 = FiltPtr - ReconPtr */
" movq %%mm0, (%2) \n\t" /* write answer out */
" movq %%mm2, 8(%2) \n\t" /* write answer out */
/* Increment pointers */
" add $16, %2 \n\t"

);

For
static const __attribute__ ((aligned(8),used)) ogg_int64_t V128 = 0x0080008000800080LL;
Put
#if !defined(__GNUC__)
#define __attribute__(X) /* nothing */
#endif /* __GNUC__)
For the assembler, you'll either have to extract it to a separate assmbly file and assemble it with as (or gas), or else port it to C.

Random Integer - Code help

Hi, I'm having a bit of a problem with a program I am making for class. I'm not asking you guys to do my work for me, I just simply need some guidance as to what I am doing wrong.
Alright, what I am suppose to write as a program that takes two user defined integers and then prints a random integer from between the two user numbers. This is the code I have thus far:
        int a = Integer.parseInt(args[0]);
     int b = Integer.parseInt(args[1]);
     double r = Math.random();
     int low = a + (int) (r * a);
     int high = a - (int) (r * b);
     int result = low + high;
     System.out.println(result);For the most part it seems to work, however it will only work if the two user defined numbers are more then 10 digits of each other. I.E. 10 20 will work fine, however 1 5 will not, 10 15, etc.
Any help would be greatly appreciated!

The question here is whether the two limits are to be included in the random range? In your solution 2000 will never happen. If you want it to it should look like this,
int result = lower + (int)((upper - lower + 1)* rand);

Sun ejb tutorial compilation problem with sample code

Can anyone help me out as I have tried several books which conveniently skip the part about compiling errors.
I noticed I don't have a CLASSPATH variable and then i created one with just '.' in it and that didn't work. any help would be appreciated as this is driving me crazy. Thanks.

Integer codes for Excel FitToPagesWide ActiveX Needed

Hello,
I am currently using LV6.0.2 and have been doing some Excel controlling in my program. I don't have the tookit so I am been doing most the Excel stuff using direct ActiveX commands.
I have gotten everything working but I am having trouble getting the FitToPagesWide to work before printing. I am not sure if there is an interger code, but if I use a I32 witha value of 1 it does not work.
This is also with Excel 97.

I have Excel 2003, but 1 is the correct setting. Try to also set the Zoom to False. Here is a snippet from the help:
If the Zoom property is True, the FitToPagesWide property is ignored.
Example
This example causes Microsoft Excel to print Sheet1 exactly one page wide and tall.
With Worksheets("Sheet1").PageSetup
.Zoom = False
.FitToPagesTall = 1
.FitToPagesWide = 1

32 bit integer size on 64 bit processor and OS

Although not strictly a dbx question, I think the audience here is the correct one to bounce this off of:
I'm curious: Why are 64 bit processes compiled with the -xarch=v9 switch having a 32 bit integer size, versus having 64 bit integer size?
Although not cast in stone, and implementation dependent, an "int was originally intended to be the "natural" word size of the processor - to use the processor's "natural" word size to improve efficiency (avoid masking, etc).".
I know you 'force' more 64 bit use (see some of Sun's doc on this below).
===============
The 64-bit Solaris operating environment is a complete 32-bit and 64-bit application and development environment supported by a 64-bit operating system. The 64-bit Solaris operating environment overcomes the limitations of the 32-bit system by supporting a 64-bit virtual address space as well as removing other existing 32-bit system limitations.
For C, C++, and Fortran software developers, this means the following when compiling with -xarch=v9,v9a, or v9b in a Solaris 7 or Solaris 8 environment:
Full 64-bit integer arithmetic for 64-bit applications. Though 64-bit arithmetic has been available in all Solaris 2 releases, the 64-bit implementation now uses full 64-bit machine registers for integer operations and parameter passing.
A 64-bit virtual address space allows programs to access very large blocks of memory.
For C and C++, the data model is "LP64" for 64-bit applications: long and pointer data types are 64-bits and the programmer needs to be aware that this change may be the cause of many 32-bit to 64-bit conversion issues. The details are in the Solaris 64-bit Developer's Guide, available on AnswerBook2. Also, the lint -errchk=longptr64 option can be used to check a C program's portability to an LP64 environment. Lint will check for assignments of pointer expressions and long integer expressions to plain (32-bit) integers, even for explicit casts.
The Fortran programmer needs to be aware that POINTER variables in a 64-bit environment are INTEGER*8. Also, certain library routines and intrinsics will require INTEGER*8 arguments and/or return INTEGER*8 values when programs are compiled with -xarch=v9,v9a, or v9b that would otherwise require INTEGER*4.
Be aware however that even though a program is compiled to run in a 64-bit environment, default data sizes for INTEGER, REAL, COMPLEX, and DOUBLE PRECISION do not change. That is, even though a program is compiled with -xarch=v9, default INTEGER and REAL are still INTEGER*4 and REAL*4, and so on. To use the full features of the 64-bit environment, some explicit typing of variables as INTEGER*8 and REAL*8 may be required. (See also the -xtypemap option.) Also, some 64-bit specific library routines (such as qsort(3F) and malloc64(3F)) may have to be used. For details, see the FORTRAN 77 or Fortran 95 READMEs (also viewable with the f77 or f95 compiler option: -xhelp=readme).
A: No program is available that specifically invokes 64-bit capabilities. In order to take advantage of the 64-bit capabilities of your system running the 64-bit version of the operating environment, you need to rebuild your applications using the -xarch=v9 option of the compiler or assembler.

I think that this was basically to keep down the headaches in porting code (and having code that will compile to both 32bit and 64bit object files). int is probably the most common type, so by keeping it at 32bits, the LP64 model has less effect on code that was originally written for 32bit platforms.
If you want to have portable code (in terms of the sizes of integral types), then you should consider using int32_t, int64_t etc from inttypes.h. Note that this header is post-ANSI C 90, so might not be portable to old C/C++ compilers.

Quit cross-posting (in different forums) every time you have a question.
Quit multi-posting (asking the same questions twice) when you ask a question.
Start responding to your old questions indicating whether the answers you have been given have been helpfull or not.
Read the tutorial before asking a question. Start with [url http://java.sun.com/docs/books/tutorial/uiswing/layout/visual.html]How to Use GridBag Layout. Of course its the most difficult Layout Manager to master so I would recommend you use various combinations of the other layout managers to achieve your desired results.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

Replace Quotes, Connection Pooling, and Sun Web Server with MySQL, Oracle

This is code I use to insert data into my MySQL and Oracle databases.
I takes care of quotes and shows use of context, i.e. when you use Sun Web Server's
ConnectionPooling. This code works. Feel free to reply if you have questions on how to set up connection pooling using Sun Web Server 6.1SP - it took quite a long time to learn and I couldn't find much information throughout the web, so I hope this helps...

This is in one class where I have a hashtable containing the
column name / value pairs that I want to enter into my table.
This class simply creates the SQL string from the values in the
hashtable. It then passes that hashtable including the database
name to a class which executes that sql statement (second code
portion).
/* Insert data into sf_parts. Create the column strings from
 * the provided hash table. Be sure to parse out hash elements which
 * are used for the createTemplate process
 StringBuffer values = new StringBuffer();
 StringBuffer fields = new StringBuffer();
 Enumeration keys = fieldHash.keys();
 while(keys.hasMoreElements()){
 Object currentKey = keys.nextElement();
 String fieldValue = (String) fieldHash.get(currentKey);
 if(values.length() >0){
 values.append(",");
 values.append("'"+fieldValue.replaceAll("'","''")+"'"); // Takes care of quotes and various other special characters!
 if(fields.length() >0){
 fields.append(",");
 fields.append(currentKey);
 sql = "INSERT INTO myTable (" + fields.toString() + ") VALUES (" + values.toString() + ");";
 String insertResult = caq.getInsertDelete(sql,"myDatabaseName"); // your database name is defined in web.xml and sun-web.xml when you use Sun Web Server's Connection Pooling.
 returnValue += " Rows inserted into table(myTable): " + insertResult + " \n";
 And, like I describe above, this method executes the sql statement.
 * Takes care of insert, update and delete requests.
 * Must have set both dbName as well as the sql String.
 * Will return number of rows affected as String.
 * @return String Number of rows affected
 * @exception SQLException
 * @exception Exception
 public String getInsertDelete() {
 checkData(); // this simply checks if the variables dbName and sql are not empty ;-)

 int rv = 0;

This is not a question and I am not looking for an
answer, but please post comments or suggestions.Using prepared statements would mean that you wouldn't have to worry about quotes.
You should be closing the result set.
You are handling all fields as strings. That won't work with time fields and might not work for numeric fields.
Presumably most of your variables are member variables. They should be local variables because that is the scope of the usage.
You must do something with the exceptions.
Hashtables although convienent mean that problems with usage can only be resolved at run time rather than compile time.

I have seen this error when I'm executing inside one of the (j2ee sun reference implementation) server containers (either web or ejb). I believe its caused by "something" having previously loaded the "sax 1 driver class". In my case, I think the container or server is loading the sax parser from a jar that contains a sax 1 version. If you can, ensure that nothing is loading the sax 1 parser from another jar on your system. Verify that you are loading the sax parser from a jar containing the latest version so that you get the sax 2 compliant parser. Good luck!

1.4 bug? or bad code? please I need help

FTPClient.getFile(inputStream out,String filename) works fine if inputStream is directed to an output file. I added a Thread to read inputStream using piped i/o and works fine but the thread never ends. Seems like readLine() does not return null. Please I need help.
note: FTP package located finj.sourceforge.net

Heres a tip: forget that open source library unless you need to customize it or something. Use the ftp library that comes wih the JDK. It is in an unsupported package (sun.net.ftp) check it out it couldn't be simpler:
//you need this import statement
import sun.net.ftp.*;
//here is example code
String server = "ftp.fileplanet.com";
String user = "me";
String passwd = "1234";
FtpClient client = new FtpClient();
client.openServer(server);
client.login(user, passwd);
client.binary();
client.cd("games");
//DO NOT CLOSE THIS INPUTSTREAM UNTIL YOU WANT TO CLOSE YOUR CONNECTION
TelnetInputStream in = client.get("pacman.exe");
//now do whatever u want with this inputstream
byte[] bytes = new byte[4096];
int x = 0;
while((x = in.read(bytes)) != -1)
out.write(bytes, 0, x);
_totalBytes += x;
out.flush();
out.close();Also another tip for you to write code in the forum put your code between the [ code ] [ code ] tags

To Verisign or not to Verisign my Code? (And which do I use?)

I have been using the netscape signing tools to sign my applet using a certificate from Netscape's Certificate Signer (in house). I am able to sign my applets and run them in IE (4.0 and 5.0) on Windows NT 4.0 without any problems. It also runs on Netscape 4.x but it does not have to run on Netscape so it does not need to be considered.
We are considering using a commercial Certificate from Verisign. The one we identified was the "Sun Java Signing Digital ID" using the "Code Signer Pro" package.
1.) Is "Sun Java Signing Digital ID" / "Code Signer Pro" package the right one?
2) Do I now use java's jarsigner tool instead of the signtool I am currently using?
Anyone have problem with that combination or have suggestions, please let me know before we go shell out $695 for this. I want to make sure that I get the right Certificate, not a "dud".

I researched this very thing almost a year ago, and in contact with Verisign they said that they did not support Java code signing yet. They suggested that we talked with Thawte and got their Java code signing certificate. We got it and it worked with the java tools no problem. The certificate was around $200 so $695 sounds a little high. I would try to contact Verisign and ask them to be absolutely sure that the certificate would work with sun's tools.
The only thing that I warn you about Thawte is that they did not contact us after we submitted the paper work to them for the certificate!! So anyone could practically claim to be a legit company and Thawte would give them a certificate!! We sent them a letter alerting them to this so maybe they've cleaned themselves up.
