Subject: Gromacs benchmark --poor performance on XEON machine
I am running gromacs on P4 Xeon machine 2.4GHz. ( 1GB memeory ) - I am using a dual CPU machine.
I have installed fftw(2.1.3) and gromacs (3.1.4 ) on my machine and I am running benchmarking using D.DPPC
I have enabled hyperthreading and I was running 4 LAM on my machine.
And I hav erun gromacs for 4 CPUS and executed the mdrun command for 4 nodes.
But I am getting a very low value compared to the one I have seen in gromacs site. I got Mnbf/s of 45 where in website It was 286 for dula xeon 2.2GHz.
I am afraid whether I am making any mistakes in installton itself....can enyone send me the detailed installtion procedure for gromacs for parallel environment.
