Sorenson Squeeze CUDA Requirements

Wednesday, June 20th, 2012
    • MainConcept H.264/AVC CUDA System Requirements
    • In order to take advantage of GPU acceleration of MainConcept H.264/AVC, the following is required:
      • Squeeze 7 or later.
      • NVIDIA video card with CUDA support (any GeForce 8, 9, 100, 200-series GPUs, Fermi, Tesla and Quadro with a minimum of 512 MB.
      • CUDA architecture 1.1 (any card except of 8800 GTS, 8800 Ultra, 8800 GTX and some Teslas and Quadros). CUDA architecture 1.0 to 1.3 implies a Tesla video card. CUDA architecture of 2.0 implies a Fermi video card.
        • I note that the exceptions do not appear to include my MacPro’s card, which is an 8800 GT (without an “S”, “Ultra” or “X” on the end)
      • Windows, XP, Vista, Windows 7 (32-bit/64-bit).
        • Minimum NVIDIA Driver version v196.21 (no Fermi support)
        • Minimum NVIDIA Driver version v196.47 (Fermi support)
      • OS X 10.5.7 or later.
        • Minimum NVIDIA CUDA Driver version 3.1.14
        • Minimum NVIDIA GPU Driver version (19.5.9f02)

GPU CUDA Driver Update for Mac BootCamp Windows 7

Wednesday, June 20th, 2012

I have various CUDA-enabled applications and my Mac BootCamp Windows 7 (64-bit) machines have CUDA-capable GPUs (Graphics Cards) but the drivers under Boot Camp make the CUDA features inacessible.

Ordinarily, for a standard windows desktop, it would simply be a case of going to NVIDIA’s site  and letting it automatically scan your system for the latest compatible driver.  However for the “shrink-wrapped” / “walled garden” world of Macs and MacBooks, the NVIDIA search result just says “contact the manufacturer”.  In other words only the driver supplied with Boot Camp is officially supported.

So in that case, what is not officially supported but does work?  Time for a web-search:

Google: [macbook pro geforce 9600m gt driver]

Obviously I will want to back everything up first…

…but it does sound worth a try.

Mac Pro: Even-Better GPU (But is too “Bleeding-Edge”?)

Tuesday, June 12th, 2012

I just saw a post on talking about the new Nvidia GTX 680 graphic card.  Much-desirable as it is in terms of graphics computing power, overall it seems too bleeding-edge for me, in terms of compatibility with my current hardware and some of my applications.


Mac Pro: Better GPU (With Decent CUDA)

Tuesday, June 12th, 2012

I’m considering getting a decent CUDA  card for my existing Mac-based system.  Currently its GPU is a GeForce 8800 GT, having 112 CUDA cores and 512 MB RAM.  In contrast, for example, the Quadro 4000 has 256 cores, 2GB RAM, memory bandwidth just under 90GB/s.  Clock speeds are harder to compare in a meaningful way, there is processor clock speed and cores clock speeds, and of course we are dealing here with multicore.

From my research, it seems that:

  • The NVIDIA Quadro 4000 is compatible with a Mac (tower) both under Mac OS and Boot Camp Windows 7 64-bit (as well as some other versions I don’t care about).
  • It is possible to install more than one such card, doubling the number of cores, and benefitting dual-monitor-related performance if the two monitors are each connected to separate cards.


Mobile Video Editing Hardware: Thoughts, Ideas & Dreams

Tuesday, January 10th, 2012

Want a mobile “suitcase” editing system, something more (and more expandable) than a laptop but not too expensive.  Primarily to be used for Adobe CS5.5 for media enhancement / editing / compositing etc.

Nearest I found was NextDimension’s range around $7000 I think (but just guesswork – could be way off – would need to get a quote).   That would (if true) be around £4500 at current rates.  Plus import…  NextDimension call such machines “flextops” (Maybe they coined the term? Google searches on it mostly come up with them.)

Apart from the (mil/broadcast-lite but me-heavy) price, it might possibly be undesirably heavy to lug around much.   If so (just guessing, not assuming), it would make more sense to go for a modular quick-setup system.  So, starting to “think different” in this direction:

  • Standard tower, capable of taking new CUDA etc. graphics cards etc. as they emerge, but no need for more than say a couple of disks, maybe if SSD could even get away with just a single disk? (For system and media – inadvisable for traditional disks of course, what about for SSD’s?  I have much to learn about SSD’s though).
  • “Laptop-Lite” to talk to it.  With robust shuttered-stereoscopic HD monitor.
  • Gigabit network to NAS fast storage (SSD and/or RAID ?).

Maybe in that case it would be far more logical/affordable to use an existing laptop as a client working together with a luggable tower server, sufficiently light and robust for frequent dis/re -connection and travel.  And remote access of course (no heavy data to be exchanged, assume that’s already sync’d).  And some means to easily swap/sync applications and projects (data) between laptop and tower, giving the option to use just the (old) laptop on its own if needed.  All such options are handy for the travelling dude (working on train, social visits etc.) who also occasionally has to do heavy processing.  Then would just need a protective suitcase for the tower, plus another one for a decent monitor for grading etc.

I certainly won’t be spending anything just yet, but it’s good to have at least some kind of “radar”.


Graphic Card Capability Determination (by test-application) for MacBook Pro (2009)

Friday, August 12th, 2011

Some software requires user-config to define whether OpenGL etc. are available.  What has my MBP got in terms of graphic card, and what aspects of it are available under BootCamp>Windows?  Below are some answers:
