I just have running hpl over 256 node with 6 cores by IB network and test is OK.
I think that HPL configration is not correct.

主题： [xcat-user] HPL problem over dual CPUs
on the new IBM 3650M3 ( dual CPUs : Intel Xeon 5675, 3.07GHz , Mem : 48G), I
want to compile HPL on it.
I use mpich-1.2.7 , libgoto2 and hpl-2.0.
When I compile libgoto2, "make" prompt : undefined symbol "RPREFETCHSIZE".
I have to use "make BINARY=64 TARGET=NEHALEM, to finish the make process.
After that, I run hpl with several blades ( 12 cores each, dual CPUs Xeon 5675,
3.07GHz, 48G), but when I use more than 7 threads each blade, the xhpl always
reports "P4_error : semget failed for setnum : 1".
If I use 6 threads each blade, everything seems good.
It seems xhpl can not run on dual CPUs ( 6 cores each CPU ), I wonder whether
there is any suggestion from the forum.
Thanks
