Looking for C Compiler Performance Info

lxrocks

I am looking for comparitive performance information for C-Compilers.
More especially in the area of Float/Integer computes.

Any information would be appreciated.

Compared to what and doing what?

Your question is far too vague [and also off topic] to really be
answered.

If you had asked this:
"I am looking for comparitive performance information for Float/Integer
computes"

I'd have recommended searching for results of these performance ranking
methods:
Linpack, Spec2000, Whetstone, Dhrystone

The problem with your original question is: "for C-Compilers." You're not
likely to find too much on this. First, "Float/Integer computes" are
predominantly CPU specific. Second, the tests are frequently written in
Fortran, not C. But, if you do many small specific searches, you might find
enough small pieces of compiler specific information, for a specific cpu,
that you could weave together to form a more comprehensive "picture".. .

Here's one:
http://www.willus.com/ccomp_benchmark.shtml

The following may provide some of the information you want. But, of course,
they made no attempt to catalog every C compiler and cpu type:
http://www.netlib.org/benchmark/performance.ps

You might also come across useful statements like this in a LINPACK FAQ:
"NOTE: Gnu g77 and gcc provide better performance than MSVC++ (Digital
Fortran) (or Watcom F77 or C), so we recommend that you use g77 and gcc. "

But, that could be many years out of date.

The best method is probably to compute the results you need by yourself.

You can find a list of (some) of the C compilers for your environment here:
http://groups.google.com/group/comp....ce45991e?hl=en
That list didn't include "Digital Mars" for the DOS and Windows targets:

Help me choose a C++ compiler to work with Python

by: rhmd | last post by:

Just found Python and I love it. What an elegant language! I would like to use it for various applications, but the mathematical calculations are way too slow (a million sines 8 seconds in Python vs. 2 seconds in Excel VBA), so was thinking of learning enough C++ to do the number crunching in C++ and integrating the C++ routines with Python.

Exceptions and performance hit

by: RepStat | last post by:

I've read that it is best not to use exceptions willy-nilly for stupid purposes as they can be a major performance hit if they are thrown. But is it a performance hit to use a try..catch..finally block, just in case there might be an exception? i.e. is it ok performance-wise to pepper pieces of code with try..catch..finally blocks that must be robust, in order that cleanup can be done correctly should there be an exception?

C++/CLI the fastest compiler? Yes, at least for me. :-)

by: Don Kim | last post by:

Ok, so I posted a rant earlier about the lack of marketing for C++/CLI, and it forked over into another rant about which was the faster compiler. Some said C# was just as fast as C++/CLI, whereas others said C++/CLI was more optimized. Anyway, I wrote up some very simple test code, and at least on my computer C++/CLI came out the fastest. Here's the sample code, and just for good measure I wrote one in java, and it was the slowest! ;-)...
