Dear Ambermd,
When i run the exact same simulation (inputs,config etc..) using the
same amber exectuables (amber22 pmemd.cuda_SPFP)
on two different computers the 3060 is 1/2 the speed of the 2060... this
should not happen should it?
cyt 115% nvidia-smi -q |grep -i RTX
Product Name : NVIDIA GeForce RTX 3060 Ti
cyt 111% grep ns/day dyn0.inf
| ns/day = 1.90 seconds/ns = 45373.30
| ns/day = 1.90 seconds/ns = 45439.35
nano 108% nvidia-smi -q |grep -i RTX ; grep -i "ns/day" dyn0.inf
Product Name : NVIDIA GeForce RTX 2060 SUPER
Product Name : NVIDIA GeForce RTX 2060 SUPER
| ns/day = 4.06 seconds/ns = 21284.54
| ns/day = 4.06 seconds/ns = 21278.81
nano 109%
As nvidia-smi reports the 2nd computer has 2x GPUS but I'm only using
one of them :-)
They are both writing to a remote sever and they are both pulling the
executables from a local /ssd directory
Any help figuring this out would be gre3atly appreciated.. b/c this is a
FACTOR of 2 difference that I just can't understand!
Thanks in advance.
Tom
