Merge pull request #368 from etomzak/master 
Fix out-of-bounds read/write in XhadFaster
 2019-09-06 19:30:52 +02:00
etomzak 9560193a9e Fix out-of-bounds read/write in XhadFaster 
Fix an error in XhadFaster where data would be written beyond the end of zgm.
The kernel loop assumed that there was always enough work for each thread to
process WPT items, but this was not enforced. It's possible to detect the
overflow with the "canary" buffer regions, but for SHAD, kCanarySize must be
~500 (much larger than the normal 127).

This commit may improve the performance of XhadFaster, since the kernel was
performing 2x work in some cases (once over real data, once over garbage).

Umar Arshad cf4907942c Remove assert for extention not available in macOS 
The cl_nv_device_attribute_query extention is not available on the
Apple platform. This caused failures during debug builds at runtime.
