Mac Pro Rack
AMD W6800X Duo GPUs
The Setup: 16800x4320 Canvas (AMD limits 16384x4214)
Using 2x BlackMagic 8K Decklinks to feed 8 groups of 1280x720 LCD panels via OceanMatrix HDMI converters to each LCD panel. BM 6K SDI-> HDMI inline.
Millumin is struggling at times depending on the content. CPU Usage is around 450%. GPU is at around 33%.
More concerning are intermittent lockups that require a hard reboot.
Everything is vanilla HAP codec.
OSX is clean install on new Hardware.
Is this 2.7Mhz Xeon to slow for good Realtime rendering?
Thank for any help.
Could you please share your project, so we could better understand your setup ? Thank you.
Here you go.
How have you encoded your HAP files?
Chunking, ‘snappy’ compression and encoder type have a huge influence on playback.
I checked your project and tehre is a lot to process : 3 canvases for an equivalent of 8 x 4K pixels, 2 x 6K video-routing and 2 x Decklink 8K Pro to manage.
While the GPU might be fast enough, there is probably a bottleneck when Millumin needs to transfer the data from the GPU to the CPU then to the Decklink. I am talking about a physical limitation, imagine how the data flow on the motherboard. This can also cause electronic components to overheat, so they would slow down a bit to cool from time to time.
To get a better idea when this bottleneck happens, display and monitor the FPS in Millumin (see "Output" menubar). Also check that your 2 Decklink 8K Pro are correctly optimized in Expansion Slot Utility.
However, keep in mind you are asking a lot to your computer. My main advice would be to lighten the burden : outputting directly from GPU outputs, reducing the resolution a bit, ...
Out of curiosity, what system/media server would you suggest that would not have this Data bottlenecking issue? WatchOut? Pixera?
This is a permanent install (repurposed), so we must get things under better control.
Thanks for all the help!
I don't know a solo "hardware+software" media server capable to output to 4 x 4K, but I can be wrong. So in your case, you would probably need to use 2 media servers, both synchronized together. This should be quite expensive (I mean more than MacPro). Please ask the manufacturer support for more info.
Of course, you can use 2 computers with Millumin in the same fashion. For sure, the MacPro handles one Decklink 8K Pro at 4320p60 (4 x frame-sync 4K).
