AMD Composability Issue on FP4, Distributed Inferencing and Wide Expert Parallelism

Evidence

While AMD performs somewhat decently on single node FP4 and performs competitively to B200 SGLang on FP8 distributed inferencing, the issue with the current AMD open source inferencing stack is that, while individual inference optimizations perform well, real customers deploy with multiple optimizations composed together. Top tier AI labs are all using FP4 **with **disaggregated inferencing with wide expert parallelism all enabled at the same time, and this is where the issue occurs.
