RE: AMBER: SANDER and PMEMD with openmpi. Failure 'make test.pmemd'

Hi Ross:
Great! Finally pmemd running with openmpi. All test PASSED, no diff file present.

I started chunk 6 from chunk 1-5 already carried out (for a large system in a POPC membrane) with sander.MPI using the command

mpirun -np 8 $AMBERHOME/exe/pmemd -O -i prod.in ....(as with sander)

where prod.in reads:

prod protein & ligand & membrane box80x80
 &cntrl
  imin=0, irest=1, ntx=5,
  nstlim=333334, dt=0.0015,
  cut=10, ntb=2, ntp=1, taup=2.0,
  ntc=2, ntf=2,
  ntpr=1000, ntwx=1000,
  ntt=3, gamma_ln=2.0,
  temp0=300.0,
 /

It is running with 0.3% MEM usage (out of the 24GB available), while with sander it was 0.4%. Of course all cpus 100%.

In view of pmemd and 8 cpus, do you see any improvement to the above prod.in?

I noticed your suggestion some time ago as to run with pmemd in chunks, though now I want to check the speed with respect to sander (and I am at modest 8 processors).

Thanks a lot
francesco
