Problem description & steps to reproduce
Starting with commit e1f15b4 my multi-gpu setup has stopped working correctly on Vulkan.
What I've noticed using
nvtopis that when the model loads, the warmup process happens only on one gpu (the 5700XT), and when I send one request to the model the processing seems to be happening only on the second gpu (the 7800XT). After some seconds the backend just crashes.Here's the command I can use to perfectly replicate the issue (of course, the multi-gpu setup is better for larger models but it's way faster to reproduce it like this):
