GUI not passing --gpu flag in autopicker

[Ricardo Righetto]

Dear RELION team,

I've compiled today the latest RELION-3.0beta source and observed that, when trying to use the GPU-enabled autopicker from the GUI, it is not passing the --gpu flag to the run_submit.script file (I'm working on a cluster with SLURM) and the job ends up running on CPUs. When manually adding the --gpu flag to the "Additional arguments" field, the job runs correctly on the GPUs. Is this a bug or am I doing something wrong?

Hi,

The Laplacian-of-Gaussian picker does not use GPU. I will make this clear in the GUI.

Best regards,

The tutorial for RELION-3 then also needs to be updated (Section 1.5). Thanks!

Sure. Thank you very much for pointing this out.

Just to clarify, I now realized that when passing the --gpu flag manually, the job tried to use the GPUs, but crashed.

Yes, the GPU code path for the LoG picker is not implemented. I will block the combination of --gpu and --LoG by raising an error.
