Dear All, I am trying to take advantage of my GPU at work, we have licenses for both multi core and single GPU usage. I installed all cuda and nvidia driver and I am able to run jobs on abaqus using GPGPU acceleration. But I noticed that often I get errors which I do not get when I submit the job only with multicore. For example I get warning "PROGRAM IS ASKED TO INVERT A SINGULAR MATRIX" , which then leads to the analysis to be terminated. I can even spot excessive deformation warnings etc. But if I turn off GPGPU is absolutely fine. I have no idea whats going on. I am working on contact and plasticity and GPGPU would be very beneficial but I cannot run a job at the moment. I have a A2000 12 GB edition and an I9 with 16 cores plus 64Gb of ram. Does anyone have advices?? Many thanks in advance!
