Dear Namd Users
I'm running SMD simulation(constant pulling force) on a protein and running
speed was good.
After a couple of hours... Running speed goes down and down.
At the beginning , speed was about "1000Steps per Two Minute" but now it's
about "1000Steps per Two Hours".
My system specifications are:
NAMD Version: NAMD for CUDA 2.7b2
Operating System: Red Hat Enterprise Linux 5.1
CUDA Version: 2.3
RAM: 24GB
GPUs: 4x Tesla C1060
CPUs: Intel Xeon 5550
Material Specifications are:
A chain of CNTN4 (four IGs) solved in a Water Box and Ions
Force is applied on center of mass
My conf.file is as same as Namd-tutorial file(for 2.7b2) except none rigid
bonds. May it relate to my configuration parameters?
Is there anybody else have had a same experience?
How can I check what is wrong?
Any help or hint is appreciated
Best regards
