sorry, I haven't time to make urgent works and my chief worries... We with my colleague (who understands in Linux a bit better me) have tried to run FF under CentOS. We satisfy all whims of Linux - set up a heap of 32-bit  ld-linux.so.2  libraries under different MPIs etc. - without any effect. Then we have tried to run the older FF version 7.1.G… Linux was silent as the partisan but after start of firefly process we forced away of it such phrase at last:

p4_error: Could not get host by name for host AMD-NEW; may be invalid name
: 107

What does it mean?

PS. I think this Linux has in a reserve much more tricks. We want to install another Linux version a bit later when I will make the urgent work. If I correctly understood, it is more preferable to install SuSE? What SuSE version is the most suitable for Firefly in my case (48-core PC)?

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…).
