GPU for Acusim

Recommended Posts



    Should be as easy as the following:


1.)  Make sure your GPU is set to "exclusive mode" by using the following command:  nvidia-smi -i 0 -c 1

     Note that this assumes the compute GPU is device 0


2.)  Then run AcuSolve using the -gpu option:  acuRun -nt 4 -np 4 -gpu


Note that we have seen the best success when using 1 multi-threaded MPI task per GPU.
