Since the science app crashed while it was listing GPU features you can use clinfo to test whether your setup works or not, waiting for APs to trash is not necessary. You also need to tell X to not touch anything NVIDIA.
Driver version that comes with nvidia-modprove is probably good but I don't really know.
OPENCL DRIVER INTEL PENTIUM DRIVERS
If you like you can alternately use the Intel GPU to drive X and keep NVIDIAs as crunching only devices, in which case you need a version of NVIDIA drivers that don't require X. Either run BOINC as root (bad idea) or add drm.rnodes=1 to the kernel command line (better idea). If that's the case then you need to run Beignet as if there is no X. You are probably using NVIDIAs to drive X. If you run Ubuntu you can find newer kernel versions in kernel-ppa, although you need to make sure your NVIDIA drivers support the newer kernel version.Īnd then there's the problem with using GPUs from multiple vendors and using proprietary drivers.
It might work if patched, 4.1 with i915.enable_ppgtt=2 on the kernel command line works and stock 4.2 should work. lib/x86_64-linux-gnu/libc.so.6(_libc_start_main+0xf5)įirst of all, which Beignet version? Since you have Haswell anything older than 1.1.0 is not going to work.Īnd then the kernel version, stock 3.16 doesn't work. usr/lib/x86_64-linux-gnu/libdrm_intel.so.1(drm_intel_bufmgr_gem_enable_reuse+0x0) May lead to reduced performance or incorrect rendering.

My machine has three GPUs (Nvidia GTX 750Ti), plus the Intel HD 4600 graphics. My experiment with Beignet doesn't appear to be successful with Astropulse 7.0.8.
