Parallel kilosort instances?

[o-zhu]

Hi everyone,

While running kilosort2 (also kilosort3), I noticed that my SSD and GPU (GTX 3070) usage were usually below 20%. Since my computer is dedicated to spike sorting, I'm thinking of ways to utilize more of its resources.

I tried running two matlab instances and sorting two datasets in parallel, but starting the second dataset (with the second instance) caused CUDA errors on the first instance. Has anyone been able to run multiple kilosort instances or sort multiple datasets simultaneously on one machine?

Thanks!

EDIT: I realized that my error was that in my initial attempt, the two instances were accidentally running on the same dataset and may have been overwriting each other. Two kilosort instances can run in parallel (using two matlab instances) but each instance seems to be at least twice as slow, so there does not seem to be any benefit as predicted..
