Reads basecalled: Metal command buffer execution failed

[vdejager]

Om MacOS M1 with 16 GB memory I get

dorado basecaller --emit-fastq ~/bin/dorado-0.0.1+4b67720-Darwin/bin/dna_r9.4.1_e8_sup@v3.3 ./fast5 | gzip > run1.fastq.gz

Creating basecall pipeline
Reads basecalled: 200Metal command buffer execution failed: 5, try #0
Reads basecalled: 300Metal command buffer execution failed: 5, try #0
Metal command buffer execution failed: 5, try #1
Metal command buffer execution failed: 5, try #2

etc. etc.
what can I do to solve this?

Hi @vdejager - are basecalls actually produced or is this error preventing that from happening?

I think this is caused by memory usage exceeding physical ram, leading to in effect swapping, causing GPU command buffer submissions to time out.

We're looking at reducing memory usage, but an interim solution would be to reduce batch size by adding -b 192.

@vdejager Dorado version 0.0.2 Should fix this problem - can you try it?
