GPU Programming on OpenBSD?
Hi everyone,
I am wondering if it is possible to develop an application on GPU for better performance. If there is one, please let me know where I can find the tutorial. Thank you |

To my knowledge user space programmers use languages dedicated to writing programs which can use GPGPU. One of them is OpenCL. I was said that open source support for OpenCL is poor, even in Linux. Support is prepared via State Trackers in Mesa.
Mesa is part of OpenBSD's xenocara repository, but Mesa is not X.Org. |

Solaris was OK until 2005-2006 I just checked Atlas, BLAS, LAPACK ports. They are in the sorry state. I am not sure if the lack of man power is the only problem or if there are genuine technical reasons for obsolete ports. If you are interested in Scientific computing stick to Red Hat Last edited by Oko; 13th November 2015 at 01:00 AM. |

This is probably OT, but I think that the best short term venue for GPGPU on alternate operating systems may be via the new SoC board vendors, who seem to be more open about releasing drivers (and some open source drivers). The MALI GPUs have good support for usage as GPGPU, and they're used on a number of SoC boards (such as Odroid). I don't know about RasPi. But, right now, (I think) you could do GPGPU on an Odroid with Linux or Android. In any case, I think the path to making those drivers available for non-Linux is easier on ARM and is perhaps less obstructed with these newer companies.
Of course, that requires an ARM port of OpenBSD to the SoC board of interest. So far as power goes, it's just a matter of clustering these low cost devices, as done for bitcoin mining. |
