[cudapoa] Kernel error #666

Open rvaser opened 2 years ago

rvaser commented 2 years ago

Hello, I tried updating GenomeWorks inside Racon from v0.5.3 to v2021.02.2 (and even v2021.02.0), and get kernel errors while using BandMode::full_band (only cudapoa is enabled, without bands):

_deps/genomeworks-src/cudapoa/src/cudapoa_batch.cuh:451] Kernel Error: Traceback in Needleman-Wunsch algorithm failed. in batch 8 Suggestion : You may retry with a different banding mode.

Got any suggestions what could be causing this? I have two tests with the same data, one with QV the other without, and the first one finishes successfully while the other yields the error above and the process hangs.

Thank you and best regards, Robert
