    Nvidia says no no no - to GeForce in the datacenter.
    posted by Julian Firminger on Jan. 3, 2018, 3:30 a.m.
    ... So the workaround is to make your farm process blockchain while idle?
    "No officer, the 1000 server farms GPUs here are mining bitcoin, only the CPUs process the VFX"
    "Prove it"
    "You prove it"

    I wonder if this is the beginning of a push to floating GRID style licensing for all commercial implementations...

    Not sure what constitutes a datacenter? They do not explicitly define it under definitions.

    No Datacenter Deployment. The SOFTWARE is not licensed for datacenter deployment, except that blockchain processing in a datacenter is permitted.

    Welcome to the world of Software defined *... Did you know they have Software defined monitor displays now too? check it out.. http://www.zisworks.com/ maybe 'open source hardware is the better way to describe it..)


    For Christmas Santa brought me an AirSpy HF+ SDR radio.

    If you were ever or are into HAM radio, short wave, listening to broadcasts with fringe/alternative content, want to listen in on Kim's Army in North Korea, see what Joe is upto in the UK, monitor transmissions bounced off the moon's surface, download in real-time satellite weather data (including sat images), or just listen to local radio stations - consider buyng an SDR (sofware defined radio)..



    Mine arrived finally this week, but not the HF antenna I need (want) to pick up the 40 meter band (its 70 feet long!!).. Its a cool little toy full of geeky goodness. I can share my raido with the internet too. You can log into its server and tune it up. You just need the SDR# software then you connect to a "SpyServer". what you end up with basically is being able to connect to a HAM raido in multiple locations in the world. Its neat stuff. YOu can find a list of ones to check out here: https://airspy.com/spy-servers/ and you don't need to own the radio, you can just download the software and start using someone else's raido. (select areas which are late at night for best reception).


    Cost under 300 dollars. There are many to choose from, I choose this one as it apparently is the best for HF which is the band I am interested in.

  • 4k video routing
    posted by Ryan Lynch on Jan. 10, 2018, 6:10 p.m. (2 days ago)
    What are folks doing for 4k / Ultra HD video routing? Our big Blackmagic Universal Video Hub doesn't support 4k and we are seeing potential for the need to distribute 4k video around the facility.

    Blackmagic does have the Smart Video Hub which supports Ultra HD but it is limited on the number of inputs / outputs.

    Is anyone using a video over IP solution for distributing video? If so, how acceptable is the compression and color accuracy?

    Thank you for your input.

    RV crashes when playing clips with sounds in a sequence on centos6
    posted by Greg Whynott on Jan. 15, 2018, 2:15 p.m. (3 days ago)
    Is that on any class of machine running 6.9? It doesn't look related but did you take a look at the other RV related posts here?

    Not a dev but looks like another Pulse related issue, looks like its wanting to do some context switch or apply a lock in kernel space but the device isn't responding. Someone here will point out where I'm wrong hopefully.

    Is that on any class of machine running 6.9? It doesn't look related but did you take a look at the other RV related posts here?

    Not a dev but looks like another Pulse related issue, looks like its wanting to do some context switch or apply a lock in kernel space but the device isn't responding. Someone here will point out where I'm wrong hopefully.

    Any recommendations for projectors?
    posted by Arturo Camacho on Jan. 16, 2018, 4:36 p.m. (2 days ago)

    We're looking to set up a small-ish screening room, 18x14 feet. Do you guys have any recommendations for a good projector? Found a thread where they talked about the DLA-Z1 from JVC and people having issues with Sony's VPL-VW1100ES (which is now discontinued). Also found some info about Sony's VPL-VW285ES which i guess it looks okay.

    No color grading being done, but some comp reviews. 

    Based in Canada.  Any recs and advice?

    Thanks!

    Has anyone gone through and tried to re-create the HMX manager config on a different machine/VM? I have two HMX Managers and both are having issues, one is hardware the other had a bad drive. I cloned the working drive to an SSD to try to recover it, but it also has some filesystem issues. I am going to reset to factory, yet again, but just wondered if anyone has managed to get it running in a VM. I'm also slightly concerned since it's Centos 5.6 under the hood. shawn To unsubscribe from the list send a blank e-mail to mailto:studiosysadmins-discuss-request@studiosysadmins.com?subject=unsubscribe

    Graphical VDI implementation for VFX pipeline
    posted by Mathew Sunil on Jan. 22, 2018, 6:35 a.m.

    Hi all,

    Has anybody successful implemented Graphical VDI implementation for VFX Studio pipeline. We are testing with Vmware Horizon, Citrix Xenserver and KVM. Hardware is HP Proliant server with 2 nos of 10 C CPU/64 GB DDR4RAM/SAS 10K RPM HDD and NVidia Tesla P40 Grid card. We are facing graphical performce degrade while accessing the VDI. We are running Linux (CentOS) VDI. Software that running on these VDI's are Silhouette v6, Foundry Nukex v11, Mocha Pro4,  tweak RV. If anyone running GPU based VDI, please let us know the basic setup and which hardware and software using for the same.

    Thanks & Regards,

    Network mapping software recommendation
    posted by Bill Heiden on Jan. 31, 2018, 7:55 p.m.

    Hi all,

     Need some recommendations for software that will produce a good network map.  I'd rather purchase a solution than try to get a piece of freeware to work.  Having decent support is also a plus.  I'm platform agnostic, even though the majority of machines are linux.  SolarWinds looks good so far.   Thanks in advance.

    Hope the government doesn't pull the plug on the M&E grant program. This is the second company I'm aware of the government granted funds to then promptly closed down or downsized. Thankfully Legend only received 180k of the 3 mill they were granted. Arc managed to get over 20 million before shutting down, to put the word 'only' in context.

    I hope all the Legend artists find new gigs quickly, and from what I hear it may be a good door opening for them... I've been told its fairly strict over there, things like track the amount of time you go to the bathroom? Could be wrong, that is what I hear...

    I assume most shops out there will have some form of workflow automation that, as it's backend, has some sort of non-propitiatory, probably open source, relational database. (Lets say mysql for example.) How much trouble are you going to for making that resource HA? And what are you using?

    We have a giant MSSQL environment, which is HA'd and DR'd up the kazoo, but I have a growing non-MS footprint of thingies that have mysql databases, some of which will be considered "critical infrastructure" before long...

    Is a sufficiently well understood combination of say Galera, InnoDB, HAProxy and keepallived considered good enough? Should I be (groan) forking out for Oracle Enterprise mysql? Thoughts hive mind?

    Wacom PTH-660 poor performance on Teradici with Centos7.4
    posted by Angelo Rivano on Feb. 12, 2018, 11:40 a.m.

    We have had a very good experienc with both Teradici and Wacom to date but we're running in to heavy lag on the new PTH-660 tablets when used with a PCoIP host card.

    If we attach the PTH-660 to a physical host the experience is as normal and PCoIP experience is good when using the previous generation of tablets. The problem only seems to be the combination of PCoIP and the new tablets. All of the Wacom functionality works, it is purely a question of lag.

    Teradici T2 cards with firmware 4.7.5 (and tried 4.9), network latency ~2ms round trip. PCoIP Linux Host Software 4.7, Wyse 7030 Zero Clients with firmware 5.5.1. Centos 7.4
