Message from cuda-memcheck

I built the application with the options below and ran on a P100 GPU.

-O2 -DHAVE_CUDA -x cu -dc

cuda-memcheck shows the following message. When similar message can be reproduced, would you please update the kernels ? If I don't build/run the program appropriately, please let me know.

Thanks

cuda-memcheck ./qs

Start by reproducing the report with cuda-memcheck on the P100 build using the listed options and inspect the CycleTrackingKernel and CycleTrackingGuts entry points. Trace the invalid read at thread (127,0,0) in block (194,0,0); done means the out-of-bounds access is corrected and cuda-memcheck no longer reports it.
