Hello,
To add to the discussion, here are some figures on
one AMD Athlon 1000MHz with 2x128MB
and using the gcc/g77 or PGI compilers
(demo version 3.2-3) under Linux (redhat 6.2).
That a USD ~1K machine...
elapsed time in seconds (non setup time in seconds)
PROWAT5:
gnu: 72.56 (71.23)
PGI: 68.56 (67.22)
PROWAT6:
gnu: 163.48 (161.63)
PGI: 108.34 (106.51)
DHFR:
gnu: 260.02 (255.02)
PGI: 215.29 (210.84)
4096WAT:
gnu: 136.46 (134.43)
PGI: 104.49 (102.75)
amber6 benchmark:
gnu: 259.07 (254.07)
PGI: 216.04 (211.59)
Any one have benchmarks on a linux cluster
with fast ethernet ou myrinet with mpich/lam-mpi?
