I check the 3 failure cases and find they are related with the bug fix in https://github.com/huggingface/text-generation-inference/pull/2444/files#diff-d8aff332cf9104dd7460d2f53575239dc1f4bcdd374e575b8a504568bfc2e078R325.
which will cause "Narsil/starcoder-gptq" 2 TP not to use exllama kernel. if you check 1TP of this model, which is using exllama kernel.
the generation result is close to the current 2TP result which is using exllama.
