    Rajesh,

     

        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.
