I am working with a research group attempting to replicate the
(normalized versions) of you results posed on the gromacs site. We are
falling short of the ps/day that you have posted.
To ensure that we are running a close setup to the environment in which
your tests were ran, Could you provide us with some additional information
that I could not find on the website.
We are running:
Dual Pentium III (Katmai) 497 MHz 512 KB L2 Cache
512 MB S-DRAM
100 MB Switched environment
Linux version 2.4.7-10smp
gcc version 2.96
Red Hat Linux 7.1 2.96-98
Dual PowerPC G4 7455, altivec supported 999MHz 256K L2 cache
2 MB at 4 GBps
1 GB DDR SDRAM
1 GB switched Environment
Linux version 2.4.20-8d
gcc version 3.2.2
Yellow Dog Linux 3.0 3.2.2-2a
1) What FFTW configuration options were used on the install?
2) What Gromacs compiler options were used on the install?
3) What hardware/networking environment were the benchmarks ran under?
4) Are the MPI tests ran so that a MPI run with 2 processes are run on one
dual processor node or on 2 different nodes?
2 processes = 1 node with 2 processors
2 processes = 2 nodes with 2 processors
Thank you for your help!
