Ab-initio stop without error message

3D Reconstruction
#1

Hi there,

I had some issues during the Ab-initio reconstruction that suddenly failed but I have no error message. I was digging into the discussion, and I found some other users that have faced a similar issue using RTX3090. Any idea what it could be and how to fix it?

Thanks,

Hi @vitorserrao,

What version of CUDA did you install cryoSPARC with? Can you also paste the output of the file cryosparc_worker/config.sh and the command nvidia-smi?

Hi @stephan,

I used cuda-11.1 and cryosparc v3.2.0. Below are the outputs:

nvidia-smi:

Thanks for your response. CUDA looks good.
Can you try this job on a different GPU or different dataset? Does the ab-initio job die every time?

#5

It worked well on the T20 tutorial that I used to check the installation. Either cryosparc or cryosparc-live worked nicely and I haven’t had any issues. It’s only dying with this particular dataset (until now). I also tried different initial models (1; 2; 4 and 6) and it’s always dying without an error message.

#6

Hi @vitorserrao,

Thanks for your response. Can you provide screenshots or copy+paste the outputs of the “Overview” tab of the dead Ab-Initio job, that includes where it dies?

#7

Hi @stephan,

Sure, this is the final part of it. Looking at cryosparcm joblog there was no apparent error message, and I just found it after a very long search on the overview (I should have found this earlier, my apologies).
It did run for a while, and then I get this message, however, there is still free space on the cards and disk.

Hi @vitorserrao,

Can you add export CRYOSPARC_NO_PAGELOCK=true to cryosparc_worker/config.sh, then re-run the job?

#9

Hi @stephan,

I already figured it out. We had some memory allocation problems that were already solved.
Thanks anyway!
