Hallo,
I do have a generell question about the use of softimage with REDSHIFT as renderer...
I do have a Maschine with 4 titan black to render with Redshift - 2 cards do speed up double but the rest of the cards do help rendering but without a scaled boost in time.
If I start 4 batch scripts with the selection of only 1 cuds device each - I do have 4 time 100% of the performance "super"...

Now my question related to RR...
Is it possible to start a job in RR which does start a job 4 times with only one cuda device selected (0, 1, 2, 3)?
or can I start one job for each cuda device separate?

Would be pleased to hear from you
Best regards

Hi

Sorry, this is not yet possible. I have added this to the GPU improvement ticket for 7.5 early next year.
You can add a flag for a job or for a client to use only card 1, but this would not help in your case.
If you do not send jobs to this machine only.


How are your other GPU machines build? Perhaps it is still possible.
