Hi guys,
I'm trying to figure out the reasoning of
* CUDAUtilities.autoThreads()
* CUDAUtilities.autoBlocks()
In the case of my old GeForge 8300 board, they report:
autoThreads = 1
autoBlocks = 8
These parameters seem to be ....
Multiprocessors x Core/MP = Cores : 1 (MP) x 8 (Cores/MP) = 8 (Cores)
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;
What's the catch?
Another question: how I could obtain other interesting parameters, like
the maximum number of threads per block ? ( Do I really need to know
what would be the maximum number of threads per block? )
Thanks a lot
Cheers :)
