backtowards ? I'll try it soon.
By the way,the application must use pgi too.But I have no pgi  software untill yesterday night. I'll try it today....

hi buddy, PGI is commercial software, you've to pay for it.

EKO pathscale is the best and pgi is the second, if you have latest EKO pathscale(purchased), i can exchange with you.(ofcoz only for personal and research use only).

Sorry, the official naming is " Legacy develop packages" during the installation of your RHEL WS.

i do think you should check your development environment and put it to the higher priority. I never have such kind issues after deployed several hpc clusters for my customers in China.

Good Luck,

It depends on your kernel version,  pay attention to kernel-EL, kernel-SMP, kernel-hugemem as well.

cat /proc/cpuinfo from one compute node , that is the first place for you to confirm your processor status.

Thanks,kernel is ok.Because I can see four cpu is working. I will try it again after a while.

BTW:It's duble kernel and duble cpu what I'm useing,The cpu's  model is AMD operton 270,Now mpi can use two cpus,but can't use four cpus,maybe mpi can't know the new cpu modle,so....

No, MPI doesn't know what type of processor you're exactly running. OS handles SMP or multi-core processor. Ofcoz the compiler will perform some optimization if you lab equip latest dual core system.
i've compiled and executed MPI based parallel codes upon dual core IA64(Itanium2) cluster and that's cool.
By the way, if you don't have 4-way(dual core) or up standing system, disable NUMA support by sending parameters to your kernel boot options. And SuSE has better performance than Redhat or/centOS on AMD Opteron system.

Good luck,

yeah,I agree with you.Because there is a YSE certification for AMD .Maybe I can try use suse.

There is a good news:Every thing is work NOW!The problem is mpirun must use rsh/ssh even on local computer.I haven't install rsh-server on it and I haven't configure mpi with ssh either,so there's something wrong.Yesterday night,I install rsh-server on the node,every thing is ok!

BTW:pgi 6.x have a tools for AMD 64 too,It's working very well.

Thanks for your advice!
