Hi,

That doesn't sound normal. Please share some log files and inputs if you
can.

[gmx-users] delay at start

2019-01-22 Thread Michael Brunsteiner
hi,
i notice that gromacs, when i start an MD simulation usuallyspends up to a few 
minutes using only one (out of several possible) threads.after a while it seems 
to have figured something out and then starts to runusing more threads. This is 
particularly conspicuous if also GPU is used.It is normally not a problem, but 
if you run a large number of very short simulations,as i do once in a while, 
this wastes a lot of time ... any remedy??
i should add that the delay i am talking about is NOT the one thatis caused by 
gromacs comparing different pme gird sizes, this comesAFTER the delay i 
mentioned and usually finishes much faster.

thanksMIchael
