To come a abreast of discussion of upgrading GSI farm to 64b CPU, I would like to start a discussion in order to find somebody who is interested to get Intel® C++ Compiler for Linux for GSI.
If you switch to this compiler you will get 17% Higher floating point operation performance and 26% Higher Integer performance. And take in account that those facts in comparing to GCC 3.4.1 (which is not EVEN used at GSI or CERN, yet)!!!
And the main: BETTER C++ processing!
Only by switching the compiler you will get almost the same performance as you can get changing the CPU. But the compiler cost MUCH MUCH less than ONE CPU!
EVEN, THE COMPILER IS FREE for non-commercial software development
Using this compiler you will find the problems in your code of which you even didn't know!

Here some Product Features
Is there anybody interested to get it for GSI development?
We can discuss and maybe propose this idea to our steering managers! to get and install this compiler as a default GSI Linux compiler or as optional one.
We obviously will gain valuable performance and QUALITY of our software with less money in comparing to CPU cost.
If we get the latest CPU it won't change the quality of software!! But better compiler WILL!
Better compiler – it is like better tool, using which, we can bring software quality to higher level.
I've been always thinking about software! This is the FIRST what should be changed to get higher performance and HARDWARE is only the last!
If program is trash it will remain to be so even with 10 GHz CPU!
Please, respond, your opinion will be very much appreciated!!!
