Hi there,

Submitting some developments for your review, as possible additions/developments of the RAWcooked website.

Thanks, Joanna

Yes I’ll try and get one encoded in coming weeks. We have a lot of encodings running at the moment to clear storage backlogs.On 7 Mar 2024, at 15:43, Jérôme Martinez @.***> wrote: @JeromeMartinez commented on this pull request.

In Doc/Case_study.md:

+### Server configurations

  • +To encode our DPX sequences we have a single server that completes this work against 6 different Network Attached Storage (NAS) devices in parallel.

  • +Our current server configuration:
    +- Intel(R) Xeon(R) Gold 5218 CPU @ 2.30GHz
    +- 252GB RAM
    +- 32-core with 64 CPU threads
    +- Ubuntu 20.04 LTS
    +- 40Gbps Network card
    +- NAS storage with 40Gbps network card

  • +The more CPU threads you have the better your FFmpeg encode to FFV1 will perform. To calculate the CPU threads for your server you can multiply the Threads x Cores x Sockets. So for our configuration this would be 2 (threads) x 16 (sockets) x 2 (cores) = 64. To retrieve these figures we would use Linux's lscpu.

@digitensions is it possible to have a rough estimate of the encoding speed with one content processed e.g. RGB 10-bit 2K. I am curious to see how the CPU behaves with one single encoding.
