While my code was running well in production using GPU_MAX_ALLOC_PERCENT at up to 100% with the 12.4 drivers, it fails (CL_OUT_OF_RESOURCES) with the 13.1 drivers (I allocate up to 90% of memory from the code). I tried changing 100% to 80% to no avail.
Only being able to use 2GB of the 3GB on the card would render it useless for my next project. I need every bit of memory I can use.
Is there a workaround?
