cryoSPARC Notices - Things to Know

...

It’s clear for most jobs whether they require GPUs or not (obviously, if the calculation has an input for the # GPUs available, then it needs GPUs!). However, some are ambiguous. We recommend you assume that the calculation does not require GPUs (if it’s not clear) and submit to `cryo-cpu`. If the calculation does require GPUs, it will almost immediately error out complaining about `pycuda`—if you see this, just clear the job and submit to a GPU-queue. If trial-and-error is not your thing, I’m sure the cryoSPARC documentation describes this in detail for each calculation
