The news doesn't mention any other opensource OS (like FreeBSD), but Phoronix is well known for its Linux relation. So, does Intel have any plans to make the Knights Corner work on *BSD as well as on Linux? Or did I misunderstood something and other OSes are already capable of dealing with this type of card? Well, this adapter card looks promising and very interesting for massive parallel applications and it would be great if the "Knights Corner" could be a an alternative for the lack of GPU support in FreeBSD when it comes to HPC. --------------enigDF66DA828C0A32ED0AB550B1 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iQEcBAEBAgAGBQJP4NCKAAoJEOgBcD7A/5N8WH8IAKtQ489OK+52Ajo7htmOUI8E yIyVjz42IcadZ+dvoKuYGzQa/sbtr79dGIcNAPZkh1BkTE6VjhG4hBYE0xA0/WjT AanAnb/hg3e0H1iaYOEp2pcPmjxfRniqi1i9uW7LNHDc4k22v6jaVDHGtpsHbfC+ 1twpBpLsXBiutSohOb8rpUDf2SfmSeNVI+gLPNvffmUTK8r+EsjZsF9FIJynfAjs lsPtDqbpuwZjXFeAzWFmDwHrreSABeKhAgWX8b9lMTcYVgUVka1SVqcT71VVqZ/h JdC9LEA/Naa2NWtYRF0FWLopJyciQDTESOHx0Zg8ZFrD+9JHFQZelmDQCMEovvs= =Wa/c -----END PGP SIGNATURE----- --------------enigDF66DA828C0A32ED0AB550B1-- From owner-freebsd-performance@FreeBSD.ORG Tue Jun 19 22:31:17 2012 Return-Path: Delivered-To: freebsd-performance@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [69.147.83.52]) by hub.freebsd.org (Postfix) with ESMTP id 3AD031065673; Tue, 19 Jun 2012 22:31:17 +0000 (UTC) (envelope-from adrian.chadd@gmail.com) Received: from mail-pb0-f54.google.com (mail-pb0-f54.google.com [209.85.160.54]) by mx1.freebsd.org (Postfix) with ESMTP id 0763A8FC1A; Tue, 19 Jun 2012 22:31:17 +0000 (UTC) Received: by pbbro2 with SMTP id ro2so11040078pbb.13 for ; Tue, 19 Jun 2012 15:31:16 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:sender:in-reply-to:references:date :x-google-sender-auth:message-id:subject:from:to:cc:content-type; bh=iPMZbvl10r1Zst9ZskfOq8r0s+/ATrA6qLdrfQDq8LM=; b=WZmZ+8iQLTBKeVvJDC3TUvp/s8futlDiGlWK2PQOWpRyTfm/DJi+mQta+1LXotqXVy K1ux8lsWx1nQMQT4ZN6hZKlwsgM9vvpcl0Q2epJfiVFAAs+HTbAAdzkUW084zhRHHpud hVpiBbYnn29CW6dCECZwfaw96pV/HGMQkV2/A8tlwtg0X5C8BuNOJHX3Xro5QvJUc6C/ 1v3pShTn+WOqyXXVtVuLH5BjQWu5ig9M/UYK0zDqymSCJHV/W+PcXGPfEAoq0ISOhbXb OIb6xPnGgYsY0UlWSSth2qQu3YPdrrckvCgmzInbpSKm6ZgV0q3BsnIceVCvJA/1Kd9L vr9w== MIME-Version: 1.0 Received: by 10.68.135.201 with SMTP id pu9mr66351713pbb.146.1340145076819; Tue, 19 Jun 2012 15:31:16 -0700 (PDT) Sender: adrian.chadd@gmail.com Received: by 10.143.91.18 with HTTP; Tue, 19 Jun 2012 15:31:16 -0700 (PDT) In-Reply-To: <4FE0D080.6020802@zedat.fu-berlin.de> References: <4FE0D080.6020802@zedat.fu-berlin.de> Date: Tue, 19 Jun 2012 15:31:16 -0700 X-Google-Sender-Auth: ZxLIVyK5YknGAGNQP1V7S7VJySE Message-ID: From: Adrian Chadd To: "O.

Let's ask them! Intel released a documentation set for MIC, which does not even contain any references to the startup sequence and system management. The only thing which is provided is patch for Linux kernel. I will be very delighted and want to appear completely wrong, but my suspect is that FreeBSD will be in the same position with MIC as it is with Intel GPUs. I asked Intel representative about MIC programming documentation some time ago, the answer was 'we do provide extensive documentation for SDK'. After I noted that this is not what is needed to support the hardware on !Linux, I only get a blank eye. --qKjsupNRLbaULa5O Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iEYEARECAAYFAk/hl04ACgkQC3+MBN1Mb4iCGACfauJDOa/A8vS8RDWB+yjYVgZa lO8An0L/vEGPYjix1K4W56ExS/TZa2Hm =I/GG -----END PGP SIGNATURE----- --qKjsupNRLbaULa5O--
