You wouldn't need MPI, just have multiple concurrent writes to a tiled EXR. We do it occasionally for stupidly big (>64K) frames. Doesn't work for deep though

- a_e_k 12y agoOff hand, I can't think of a reason why it wouldn't work for deep, too, other than perhaps disk space and I/O. Why do you say it wouldn't?
- boulos 12y agoHi Andrew ;). I've never dealt with the new OpenEXR 2.0 deep stuff, but looking at the spec (http://www.openexr.com/openexrfilelayout.pdf http://www.openexr.com/openexrfilelayout.pdf page 13) the Deep Tiled stuff seems to totally be ready for this. I would have guessed that there might have been some global compression option that wouldn't be workable, but the design clearly does this all per tile instead.
- berkut 12y agoIt would in theory work - our solution doesn't at the moment.
