I'm trying to set-up a Lustre master station for color-grading.
As for now we're performing some tests on an avid-station built on a HPwx8400. The station has 2 dual-core processors, 3gb ddrIII ram, a nvidia fx1500 graphics card and 3 scsi-disks. We're working in full HD-resolution, 1920*1080, 4:4:4 10 bit. We're using .dpx-files for grading.
The prestanda is pretty good, but still we're having some troubles with the material. When grading the computer starts to loose prestanda. We're working with a material with a total length of no more than 9 seconds (I think the .dpx-files has a size of about 7mb per frame, which gives a total size of about 2gb (for 9 sec)). We haven't learnt the program good yet, so that could be one reason. Also the program has a special gpu-button for grading in realtime. Does every graphics-card has a gpu (i'm working on a nvidia fx1500)? And what really does the gpu? Furthermore, maybe we have to few scsi-disks?
Also this is a testing-station; if it works we're thinking about building our own station. I wonder if it's possible to get a way a little cheaper. Do I have to have these very expensive graphics-cards if I don't need the special outputs/inputs (thinking about renting equipment just for the transfer of material)? Should I put the money on scsi:s, ram and processor-prestanda instead? Also it would be nice if the computer could handle 2K in the future...
Could anyone give me some feedback on this one?
Best regards
