Hi, I've been programming using OpenMP and the Intel Fortran Compiler for some time now. I program under Linux environment (Ubuntu) and all the programs are tested on my laptop (2-core) or on a 4-core desktop.

The programs are engineering programs so they are computationally intensive and strictly mathematical (no web applications or graphics etc) I want to buy a "stronger" machine with more cores but keeping the shared memmory architecture. I need to be able to continue programming with OpenMP or in the future with TBB and continue programming under Linux. I received the following offer by a company:

• 2 x processeurs Intel Xeon E5620 4 curs par proc. 2,4 GHz - Turbo up to 2,66 Ghz
  ou
  2 x processeurs Intel Xeon E5645 6 curs par proc. - 2,4 GHz - Turbo up to 2,66 Ghz
  ou
  2 x processeurs Intel Xeon X5675 6 curs par proc. 3,06 GHz - Turbo up to 3,46 Ghz

• 5,86 GT/s. FSB 12 MB cache par processeur

• Carte-mre Intel S5520HC Intel S5520 Server chipset

• Mmoire de 24 GB UDIMM ECC 1333

• Disques de 500 GB server class 64 MB cache 7200 rpm
  

• Contrleur graphique ATI 16 MB intgr (basique)

• Graveur DVD Sony 16 x interne

• 2 x Onboard Gigabit ethernet connexions

• Botier 4U Alimentation 850W + 4 x ventilateurs

Sorry for the french but I think you get the meaning. Is this formulation good for me? I mean the 2 XEON cpus see the same memmory? Will I be able to run my OpenMP parallelized programs under Linux like usual?

Any suggestions that will help to look better? Even any suggestion for a Shared Memmory architecture computer with more cores than 12? Thanks in advance, Petros
