Re: Gridcoin (GRC) - first coin utilizing BOINC

Hey!

Been playing around with Gridcoin, my first attempt at mining cryptocurrency, and I found a bug with the cgminer instance config generation. I described it over here and will try to summarize it:

Here's how the configuration panel looks in gridcoin-qt:

After creating the cgminer instance, cgminer wouldn't start. Here's some info:

Code:

cgminer.exe -c cgm0 -T

After doing some research, I fixed the problem by manually changing the "gpu-platform" setting in cgm0 from 0 to 1.

Hope this helps anyone else having this problem and that there will be a fix in the config generation in an upcoming version of Gridcoin (recreating the instance sets the setting back to 0).

Oh and happy new year!
