Hi all,
I'm using NAMD to perform some MDs.
I've noticed that on the same hardware (IBM x3665 dual opteron dual core
(rocks 4.3 32-bit version)), using the TCP binaries and charmrun of the
last NAMD release, sometimes the CPUs (on similar biosystems and same
dyn protocols) goes to 60-80 %...the starnge thing is the different
So I'm asking to some gurus overthere if there is a better way to gain
The network is gigabit (2 eth devices each node). 15 nodes.
Rocks 4.3 based on Centos. Openmpi and mpich installed.
Could someone point me out the right way to test?
Thanks a lot
