Hi dsk,

Thanks for the reply. As far as I can remember, the kernel was still under the 85% logic utilization threshold mentioned in the Quartus OpenCL SDK optimization guide. I checked both .log files for errors, but found nothing except for two errors mentioned under warnings. I don't recall running anything alongside the compilation, and the system had about 32GB RAM I think. I left it running overnight.

I've had no-fits before when the quartus_fit ended unexpectedly, and the error showed up in the quartus_sh_compile.log, but in this particular case there wasn't any mention of that error, so I found it pretty baffling.

I appreciate the heads-up on the 14.1 error messages. Understandably the OpenCL SDK is still relatively new.

Kind regards,

Victor
