LLVM/CLANG and several OpenCL projects: FreeBSD or any *BSD developer involved?

2011-10-20 Thread Hartmann, O.
As I'm not a developer, but for scientific purposes highly interested in using GPUs, the only way of doing HPC computing at the moment is with nVidias TESLA/nVidia consumer graphics cards and LINUX, since on Linux one willing to use the GPU has the necessary libraries, driver and compilers. I'm ho

sysutils/sge6[012]: Sun Grid Engine - still broklen due to utmpx?

2011-09-23 Thread Hartmann, O.
I was wondering if the SUN Grid Engine, located in port sysutils/sge6[012] is still broken due to utmpx. My department uses this GRID engine on Linux and since a long time I wish to use it also on FreeBSD. Are there alternatives? What are people using on HPC FreeBSD? Greetings, Oliver __

FreeBSD and GPGPU on nVidia (OpenCL/CUDA): Pathscale and "open" compute driver

2011-09-15 Thread Hartmann, O.
Just read this on www.phoronix.com: http://www.phoronix.com/scan.php?page=news_item&px=OTkxMA Does it sound promising? It seems so. Even if this would be a commercial product which would fits into FreeBSD's gap of having GPU compute support, this could be an affordable solution.
