* Attempt to run multigpu in PR CI for now to ensure it works * fix yaml file * forgot to include multigpu tests * fix call to cicd.multigpu * dump dictdefault to dict for yaml conversion * use to_dict instead of casting * 16bit-lora w flash attention, 8bit lora seems problematic * add llama fsdp test * more tests * Add test for qlora + fsdp with prequant * limit accelerate to 2 processes and disable broken qlora+fsdp+bnb test * move multigpu tests to biweekly
