but not in the same way! the first job uses 8 pools of 16 processors,
the second
1 pool of 128 processors. The first choice seems to be reasonable,

are using intelmpi 4.0 in http://cystorm.ece.iastate.edu with a very good
performance .. but we are not sure now ... let me explain :
We use a surface of Al with 81 in 128 cpus using intelMPI and openMPI 1.4
The compilations options (make.sys), input file and output files are in
We have been using mpiifort and mpiicc without major issues. If my
memory serves me well they use the intel mpi libs while

Dear Tran,
here are the Q-E tests for CP in a Q6600 :

If you get the same performance, things are running ok.
Always set the system varable OMP_NUM_THREADS to 1, otherwise

with my old parrallel machine).
I read the messages from our forum, especially
