Hello All!
I have a cluster consisting of 12 dual socket E5-2650 10-cores 64GB memory compute nodes.
I ran the mkl single linpack benchmark and I got around 650 Gflops which seems to be reasonable.
However, when I tried to run the MP_Linpack with mpirun -np 80 -hostfile hostfile ./xhpl_intel64, (hostfile has 40 lines of compute101 and 40 lines of compute102), I get a result of 161 Gflops. Shouldn't I be getting a result around 1300 Gflops?
My HPL.dat has problem size of 72192 and P 8 and Q 10.
Can anyone help me out?
Cheers!
Simon.
