Hi,<div><br></div><div>I'm running mpi jobs on a small cluster that has several machines with CUDA enabled devices. I'm trying to add gpu acceleration to my computations, but I'm having issues executing CUDA code while running the processes as an mpi job. The gpu logic works fine when the application is executed as an independent process.</div>
<div>I guess there's something in the way smpd launches the job and prevents the process from properly accessing the CUDA driver(and device). Most probable cause is that smpd is running as a Windows service and not as an interactive console session. Is there a way to tweak smpd or mpiexec in order to have CUDA access for the jobs?</div>
