Hi,
What happened to the OC2 Beam kernel for 1070?
Hello,
--oc1/oc2 didn´t work on any algo for me. Not on Beam, not on Zhash/144,5 and so on. It says every time no oc1 or oc2 for this algo.
Hi sxemini, Kringel, and everyone,
we are sorry the message about oc1/2 usage was not clear before.
miniZ introduced a warning in version v1.5t that calls the user attention when the GPU does not support oc1/oc2, for a certain algo.
When this happens the GPU will run the default kernel, which is the best kernel we found for that GPU. It does not need oc1 or oc2 kernels for best performance.
Not all GPUs and algos have oc1/oc2 available. Some do because we realized that, for some the OC settings that you choose, those GPUs (the ones that have extra kernels available) may benefit by running a kernel other than the default.
From version to version the existence of oc1/oc2 may change. For detailed information about this, please check the dedicated information in FAQ page: https://miniz.ch/faq/In summary, the warning is informative. There is nothing to worry. You can just ignore the message. GPU should start the default - best - kernel available.
However, do let us know if you find a regression for your GPU. We do not have access to all different GPUs available.
It can happen that you find minor improvements (or even no improvements) for a minor number of GPUs but we do not expect regressions to occur. So keep us posted if this happens.
This is the only way we can know and try to check/correct the issue.
Thanks a lot for your feedback!
Cheers
