IndexError: list index out of range

[Peter Michalski]

Hello,

I am trying to run examples (no CUDA GPU) but keep encountering the same error, I have tried restarting my box (which solved this issue for another user in 2016 - https://groups.google.com/forum/#!searchin/sailfish-cfd/index$20out$20of$20range%7Csort:date/sailfish-cfd/A69KwBYE59A/KLUWDiBJBAAJ ). Any thoughts on how to fix this?

Hi,

Well, we did not update opencl backend for many years. 

CUDA is the only way to go for now. 

the best
