* Fix garbled output with REPACK at high thread counts Fixed a race condition in the REPACK matrix multiplication code that caused garbled output when using 26+ threads (model-dependent threshold). The issue occurred because with high thread counts, the code forced chunk count to equal thread count, creating many small chunks. After aligning these chunks to NB_COLS boundaries, adjacent chunks could overlap, causing data corruption and race conditions. The fix enforces minimum chunk sizes based on NB_COLS and caps maximum chunk count to prevent creating too many tiny chunks, ensuring proper alignment without overlaps. * Update ggml/src/ggml-cpu/repack.cpp Co-authored-by: Georgi Gerganov <ggerganov@gmail.com> * Update ggml/src/ggml-cpu/repack.cpp Co-authored-by: Georgi Gerganov <ggerganov@gmail.com> --------- Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>
* vulkan: remove the need for the dryrun Allocate pipelines and descriptor sets when requested. Reallocate the prealloc buffers when needed, and flush any pending work before reallocating. For rms_partials and total_mul_mat_bytes, use the sizes computed the last time the graph was executed. * remove dryrun parameters
