Thanks for your effort. I also get segfault on this: http://documen.tician.de/pyopencl/ I have this: 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF114 [GeForce GTX 560 Ti] [10de:1200] (rev a1) (prog-if 00 [VGA controller]) Subsystem: ZOTAC International (MCO) Ltd. Device [19da:1665] Flags: bus master, fast devsel, latency 0, IRQ 24 Memory at fc000000 (32-bit, non-prefetchable) [size=32M] Memory at d0000000 (64-bit, prefetchable) [size=128M] Memory at d8000000 (64-bit, prefetchable) [size=64M] I/O ports at e000 [size=128] [virtual] Expansion ROM at fe000000 [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: nvidia If I understand the idea behind ocl-icd, this will be great once it's done.
