Dear Amber users/experts,
I'm running at TI calculation on CPU but it is expected to take 353 hr to
complete.
When I tried to run the same on GPU with pmemd.cuda I'm getting hte subject
error mentioned below.
Can someone on the list please guide me if there is a way around this or is
it not possible with Amber18 on GPU?
Additionally, I was expecting free energy values in the range 100-115
kcal/mol, but I'm getting 180 kcal/mol values. I did run a 30 ns
simulation on the model compound but values did not change much. I used
procedure similar to that given in the tutorial here
<
http://ambermd.org/tutorials/advanced/tutorial6/section4.php>. My system
is Heme with and without extra electron, charges were derived from MCPB.py
tool.
We are processing the purchase of Amber20, but it might take 15-20 days or
more before the payment goes through. Is this something available in
Amber20?
thank you and best regards.
