I am calculating a system of 700 aa protein in a water box (15
angstroms around the protein), using electrostatic switch 10A and
cutoff 15 A. PME is off. The estimation on 64 Intel Xeon 3Gz cores is
0.44 days/ns and about 4 days for 10ns. I was using intel compilers,
mvapich and the following options
CHARMM: ./build charm++ mpi-linux-ia64 icc ifort --no-shared -O
NAMD: ./config tcl fftw Linux-ia64-MPI-GM-icc
and I use mpirun -np 64 namd2 <config> to run the program
I was using gromacs previosly and I find it to be 10 times faster.
My question is -
is this a common estimate for a system of that size or I have problems
with my cluster or my installation?
