Hello,
I’m currently working on some code that needs to repeatedly launch a kernel with a slightly different thread block each time. However, some of my configurations do not work.
When using a {1,1,256} thread block I get an “Invalid Configuration Argument” error.
However block configurations of:
{2,1,128} {4,1,64} {8,1,32} and {256,1,1} work just fine.
What is the reasoning for this? My kernel only uses 12 registers so I don’t think I’m running out of resources. Any help would be much appreciated.
