Afternoon!
I've been working with a HPL run on a LARGE Linux cluster running RH7.3.
(Kernel 2.4.19-27.7.xsmp, if I remember correctly..) I installed the stock
6.5.9 rpm from the ftp site.. It seems to run extremely well until I
approach
1024 nodes.. We thought it might be the number of file descriptors on
node0, but a recompiled kernel with 4096 descriptors didn't seem to help..
It's running very well with 1008 processors currently.. Any pointers or
suggestions where to look/tinker/recompile/debug would be appreciated!!
I will, of course, provide a synopsis for the list after we fix this.. Oh
yes,
the HPL application was compiled with the standard RH7.3 compiler suite..
I do have the Intel 7.0 compiler suite available, if that's any help..
THANKS!
Steve
