As the principal author of the MPSKernel class, while I applaud your bravery and ingenuity, I can’t say that this is at all recommended or tested. I am surprised it did not assert due to missing library or similar infrastructure that we add to all of them.
This was in the “dumb party tricks” category even at the time (>2.5 yrs ago!) If I were doing this today, I might borrow the Interface, but I wouldn’t piggy-back the implementation.

While I have you on the line, though: can you characterize the overhead of generating a command encoder for every encoded kernel? Why not take an encoder instead of a command buffer?
Thanks. Twitter will use this to make your timeline better. UndoUndo

Compute encoders are cheap. They do not have a mountain of state attachéd to them like render encoders do. In addition, the driver can fuse them so you don’t take a hardware kick cost. The design allows us to avoid having to define which binding ids are volatile.

Makes sense. Thanks for the explanation!
