Hello! I want to use NVidia Tesla K40 GPU for parallel computing.Does FreeBSD support such a hardware? Thanks a lot!

No, FreeBSD doesn't support GPGPU computing on modern g= raphics hardware. Since 2009 we try to utilize FreeBSD for such a purpose, especial= ly with the use of OpenCL for high performance computing. Around 2010 there was the glimpse of a dawn with Pathscale, offering a Open= ACC-precursor with their compiler infrastructure, supposed to be capable of utilizing Fre= eBSD and nVidia GPUs (that time Tesla) with Pathscale-libraries (I forgot the name, = it's CAPS or something like that) but at the end it revealed its self as a heap of unfin= ished, unmature code and by now the company or ist successor doen't even provide a= commercial product for FreeBSD - the project died! It is even worse: FreeBSD ports dropped Nouveau! There are effords bringing= libclc, the new Mesa library, Glover and OpenCL in combination with LLVM 3.4/3.5 togeth= er to provide OpenCL and via LLVM the nVidia PTX backend, but as far as I know this work = is still under development and immature and FreeBSD is no longer part of the scene due to = the drop of the Nouveau driver (I was told FreeBSD lacks important kernel features know= n for years for KMS). CUDA is completely out of view: nVidia doesn't provide support for FreeBSD.= nVidia fellows claim there is no need/request from FreeBSD people. I believe it is= simply ignorance and a stupid political issue, made years ago, that we suffer from= by now. The situation with open source AMD driver (radeonSI) is unknown to me. We m= ade very bad experiences with AMD hardware in the era of the AMD HD46XX/47XX and HD48XX = chipsets and the development is/was behind the recent chips available on market. On Linu= x there were reports of successfully running OpenCL kernels on the radeonSI drivers with= Glover/Mesa and other mandatory software not available for FreeBSD - the FreeBSD X11 ba= se system is also "methusalem" and behind the recent development. If you would go with A= MD, you would have to stay with open source since AMD doens't provide BLOBs for their GPU= s for FreeBSD. For Linux, the AMD OpenCL SDK is very nice, their hardware is pretty fast (= > nVidia!) while their driver tend to crash. But as said, Linux only. With nVidia you get a pretty fast and nice BLOB for all FreeBSDs and modern= GPUs from nVidia, but there is no OpenCL backend lib (or CUDA). Either way, it is a d= ead end with FreeBSD. There was also once a setup with the FreeBSD Linuxulator - but this is 32bi= t only and a no go for serious scientific compuations. We also tried this with more mode= rn FreeBSDs (8.X, 9.X, 10-CURRENT that time), but with CUDA > 4 you're out of luck. And= FreeBSD doesn't have a 64bit support in the Linuxulator. And why running a Linuxula= tor? If you really plan to use a beast like K40, consider dropping FreeBSD and u= sing Linux! We started with Ubuntu and OpenSuse that time. At the first moment the shock i= s heavy, but you'll come along with Linux very soon. The only bad thing is the missing Z= FS support as someone might be used to in FreeBSD but this is also only a question of tim= e (more short than long!). Linux development is pretty fast these days, support is excell= ent and Linux suffers from bad karma from the days of the Linux 2.4 kernel. That has chan= ged dramatically. A department developing security facilities is now dropping O= penBSD in favour of Debian Linux, even OpenBSD is still considered more "bullet proof= ". But the decision was made due to a dramatic driver issue - I mention this here beca= use also FreeBSD seems to suffer increasingly (compared to to Linux) from driver iss= ues for high performance equipment (special interlink adaptors, WiFi NICs and even the G= PU issue!). I'm very sad having no better experience to tell. oh=20 --Sig_/9fRoOlzUZ2xHOP9eXP3+l48 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJUU9Z+AAoJEOgBcD7A/5N8fN0H/jd/KQHwRiqf6biAC4X248ba RKyuGQsfGgMlH9v6GCAHEsoTdveR/9sgZjbGThAaqZtCcKc+TTTzolJI7j0xoljI POQ+7RrXm0m9kPNjErEQLnonWuqBPsUAunVRoaAgtRTLUlMeSRgIoIgqPhT2g7Nx Dtsxm1tlg+BIL/amhbF4DQLrUYF50lTvkw7B/8JIWIL1lZ4PACcoDDNqdpnhPpu4 GYocWPpHd0McSxryl+xH2TMrDSgLMwdU5gkz/s84LY1bZvTPOmncreNeg3PlC8p0 KawGIttlR0vgxBiLK6NhW5kAJmOx6FiMLf3XwGlrl/lRAtk4uVOmJiraBqSDn20= =D9/f -----END PGP SIGNATURE----- --Sig_/9fRoOlzUZ2xHOP9eXP3+l48--
