In the case of my old GeForge 8300 board, they report: > > autoThreads = 1 > autoBlocks = 8 > > I've never heard of an 8300, I assume it has 2/16 of the MPs enabled?
They should never return that, they should return threads as a multiple of 64 and blocks as a multiple of 2. It could be there is a bug, or that you are executing the kernel on the host. > This is weird or a big and unprobable coincidence, but in > x10-runtime/src/x10/x10/util/CUDAUtilities.x10, these values are > hardcoded like this: > > public static def autoBlocks() : Int = 8; > public static def autoThreads() : Int = 1; > > Those are the values for CPU execution.

We would probably expose it through a general purpose info database for places, with all sorts of stuff available. The key thing autoBlocks/autoThreads does is it knows things about the kernel being executed, like the number of registers and such. ------------------------------------------------------------------------------ Beautiful is writing same markup.
