Subject: meta : Add missing `buffer` set in allreduce fallback !COMPUTE clear (#23480)
X-Git-Tag: upstream/0.0.10438~1035
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=33c718db1fbfe834f30eef28cf206f98736fe612;p=pkg%2Fggml%2Fsources%2Fllama.cpp

meta : Add missing `buffer` set in allreduce fallback !COMPUTE clear (#23480)

Without this at least the vulkan backend will skip the `* 0` for
!COMPUTE tensors, causing corrupt output.
