Hello Mr. Roberto Bagnara,
Dear Patel,
please accept my apologies for the delay in answering your message: your letter arrived in a very busy moment and I had to postpone replying.
My name is Jayesh Patel (J.D.). I work for Intel as a Compiler TCE (Technical Consulting Engineer). I recently worked on resolving one of your issues (#523343 - Internal error compiling GMP 4.2.4). I am glad to inform you that I have taken over PPL/GMP related tasks at Intel.
This is very good news indeed.
I also wanted to inform you that:
I will work on Intel compiler related issues reported by you or your team.
Good. There are several still open.
I will reproduce working environment of up-to-date PPL/GMP in Intel lab, and compile it with major releases of the Intel compiler.a. I have already downloaded PPL-0.10 and GMP-4.2.4.
OK. We are in the process of releasing PPL 0.10.1. If you want, you can access our Git repository: http://www.cs.unipr.it/ppl/Download/Git
b. I have managed to compile both PPL and GMP successfully using Intel compiler 11.0.086.
Did your builds pass `make check' both for GMP and PPL?
c. However, using GCC-4.3.0 gets me error "configure: error: Cannot find GMP version 4.1.3 or higher." 3. I also intend to benchmark Intel compiler optimized binaries of PPL/GMP against GCC compiled ones. a. What are the performance benchmarks for PPL/GMP that you prefer to focus?
One benchmark that is significant for all the applications that work on polyhedra is described at
http://www.cs.unipr.it/ppl/performance
When we will be able to build the PPL with the Intel compiler and let it pass `make check', we can help you to reproduce this kind of experiment.
b. What is the typical execution environment (h/w and s/w) for PPL/GMP based applications?
Speaking for the PPL only, I think the majority of users works on Unix-like system, with a preference for GNU/Linux. In your shoes, I would test on recent versions of Debian and Fedora.
c. I have also recompiled both PPL and GMP with optimization flags for Intel compiler.
The PPL configure script already recognizes the Intel C/C++ compiler. If you let us know which flags are suitable, we can use them as defaults.
Please let me know what you think. Looking forward to working with you.
Thanks.

Sure. Sorry again for the delay. All the best,
Roberto
