Dear all,
I was testing NAMD-CUDA (precisely NAMD_2.8b1_Linux-x86_64-CUDA)
on my GPU workstation which has:
- two Tesla C2070 boards
- one GeForce GTX 470 card
- Intel Xeon E5620 Processor, 2.40GHz (Quad-Core/8 thread SMT)
The system under investigation is an 11 residues long peptide immersed
in a TIP3P
water molecules box (truncated octahedron), with a total number of atoms equal
to 14038. The simulation conf file is attached.
I would like to know if the following computing times are OK,
or there are some improving settings (hardware or software)
that I am missing in my machine:
- CPU run with 16 processes: 14m 29s
- GeForce GTX 470: 20m 33s
- 1 Tesla: 21m 02s
- 2 Teslas: 13m 02s
- 2 Teslas + GTX 470: 10m 13s
I am asking this mainly because I would expect that one Tesla C2070
was anyway faster than one GeForce GTX 470 and 2 Teslas faster than
the CPU, am I wrong?
Many thanks in advance.
Best regards,
MP
