Parallel Studio on Win7 or Linux Gentoo

[parallelspeed]

Hi,

I'm really interested to go with Parallel Studio for an optimum use of our "Intel i7 cores", but I'm still confuse on which platform to use.

Not sure to go on "Win7 Unmanaged C++" or "Linux Gentoo C++" (compilation optimized for my hardware).

I DONT want to start a Win/Linux debate here. I just try to look at the fastest platform to run my C++ multithreads server app! I dont find this kind of benchmark on web (comparaison ICC/TBB on both platform )

Thanks for your help.

Hi, (Edited this post so it's clearer)

Presently, the released Intel Parallel Studio 2011 should work fine on Windows* for performance, and is for parallelism development and performance solutions for developers using Microsoft Visual C++*.

Yes, we do offer Linux solution today (in addition to support for Windows*) with ourreleased products (Compilers, Libraries, Performance Analyzers etc) as below:

1. Intel Compiler Professional Edition for Linux* (For C/C++ and Fortran...)
Note: This product does contain the Intel Compiler, libraries (Intel Threading Building Blocks, Intel
Integrated Performance Primitives, The Math Kernel Libraries too)
2.Intel Threading Building Blocks for Linux*
3.Intel Integrated Performance Primitives for Linux*
4. VTune Performance Analyzer for Linux*
5. Intel Thread Checker for Linux*

You can visit the link http://software.intel.com/en-us/articles/intel-sdp-products/to browse the various offerings available as of today for Linux.

With that said, the presently released Parallel Studio 2011 is for Windows* only but future updates may be offered this year offering a Linux solution and I'll keep you posted when that happens. BTW, presently there is no support for Gentoo with our linux offerings but there should be no reason that it shouldn't work on Gentoo, just FYI.

Hope the above message is more clearer and answers your question?

Thanks.

In that case, if I ask you again the same question about only Intel ICC & TBB products, between Win7 and Linux ... do you have more infos? Performance difference ...
Because it looks like ICC & TBB are supported on both. Using ICC & TBB , do we have benchmark on which one is most faster (for same C++ code)?

Hi,

Pardon me, I edited my previous response to make it more clearer as I implied that your question was on Linux support in Parallel Studio only? Since we already have Linux Support readily available in our released products (Compiler, Libraries, Performance Analyzers and so on...) I took the liberty of editing that post again so it's clear we do support Linux now in our tools!

OK, to your question on performance between Windows 7* and Linux for the same code on which is faster? Well, I don't have specific numbers right now but let me check and see if I can find any standard benchmark data (like SPEC*) etc., and will update you accordingly?

Thanks for your answers,

If you make some benchmarks, it will be appreciate to compare results.
Because the reasons to buy i7 multi cores is the possibility to high speed executions ... when we buy specific tools & development product (hardware specific) we try to find the optimum OS to run it , at the same time.

Hi,

Firstly, glad to know youre planning to buy i7 appreciate much. Also, I couldnt find data handily available that compared identical code on these two different platforms.

The best thing to do is to go to http://www.spec.org/ and look at the various benchmarks available and look at the spec rate results (Speed, Throughput, etc.) Also, the performance really depends on the application per-se. With that said, it would be good also for you to evaluate your application for performance on these different platforms and go from there?

Hope the above helps?
