Some tests fail with NVIDIA GPUs on Mac #111

Open eholk opened 10 years ago

eholk commented 10 years ago

Some test cases, like nbody.kfc and nbody2.kfc fail on Macs when using an NVIDIA GPU.

See the discussion thread at https://groups.google.com/d/msg/harlan-dev/l-W0xXQJPKY/Uw8K_z6gEe0J for more details.

I am in similar issue, but different failures:
