I've got a bit of a silly question here folks, nothing I have actually tried yet.. I have an MPIEXEC install of JtR, 10 nodes (48 CPU cores) I literally have just plonked in my first CUDA card and not even powered it on yet to install the nVidia drivers. I am a little concerned, I will reinstall JtR on my MPIserver which uses Ubuntu 14.4LTS server install.. Of which I will include the flags for CUDA support... I know this sounds really really stupid, but when as I have done launch -n 48 (48 threads to run on 48 CPU cores) do I now have to spawn -n (number of CPU and total number of GPU cores) You can have a good giggle later on at me, trust me any help is much appreciated indeed with regards to this matter. Kind regards.
