In this connection what can you tell about SuSE and CentOS? Or how I can know what kind of libraries use these Linuxes?


>>4) What kind of Linux is the most suitable for 48-cores AMD computer in your opinion? Now I have CentOS-6.2-x86_64 on this PC. May be, it should replace on some other kind of Linux?

Three years ago I  used SuSE (10.1 or 10.2) too. However at some moment SuSE started to run unknown process. In some minutes after I killed him, it was again running and speed of calculation decreased in 2-3 times. Nobody could understand what for this process is started and what it does. Then I have quarrelled about Linux :-).
As for my CPU model I have on 48-core machine four 12-core AMD Opteron Processor 6180 SE 2.50 GHz and CentOS. This system is not so friendly to the user and I would prefer to replace it, if there is more suitable system. I cannot to install driver for CUDA in CentOS (strange problem…).

Thank you very much for your help!
