Eliminates blocking queue.wait() for better async performance. * Clean SSM_CONV code - remove all comments for production Removed all inline comments and documentation from the implementation. Clean, minimal code ready for production merge. * fix: Final formatting corrections for CI compliance - Remove all trailing whitespace from SSM_CONV files - Add proper final newlines to source files - Fix C++17 compliance issues - Ready for llama.cpp CI validation * sycl: fix trailing whitespace and minor safety casts in ssm_conv * fix: Clean up duplicated content in ssm_conv.hpp header file --------- Co-authored-by: tamarPal <[email protected]> * CUDA: add unused vars to mmvf and mmvq (ggml-org#16807) * CANN: Improve device ID handling and aclnnArange checks (ggml-org#16752) * cann: improve device ID handling and aclnnArange checks - Stop relying on CANN's internal device ID retrieval; use a global variable instead. - Enforce stricter dimension validation in aclnnArange for better compatibility across CANN versions. * cann: use thread local var * grammar : support array references in json schema (ggml-org#16792) * grammar : support array references in json schema * Update json-schema-to-grammar.cpp Co-authored-by: Sigbjørn Skjæret <[email protected]> * grammar : improve regex when naming ref derived rules * grammar : replace non-conformant definitions array with anyOf test case --------- Co-authored-by: Sigbjørn Skjæret <[email protected]> * llama: consistent ctx <-> buf order for KV cache (ggml-org#16746) * embedding: add raw option for --embd-output-format (ggml-org#16541) * Add --embd-output-format raw for plain numeric embedding output This new option outputs embeddings as raw space-separated floats, without JSON or 'embedding N:' prefixes. Useful for downstream vector pipelines and scripting. * Move raw output handling into format handling section * Move raw output handling into else-if block with other format handlers * Use LOG instead of printf for raw embedding output * docs: document 'raw' embedding output format in arg.cpp and README --------- Co-authored-by: Xuan-Son Nguyen <[email protected]> Co-authored-by: Johannes Gäßler <[email protected]> Co-authored-by: Acly <[email protected]> Co-authored-by: Diego Devesa <[email protected]> Co-authored-by: Yuri Khrustalev <[email protected]> Co-authored-by: tamarPal <[email protected]> Co-authored-by: tamarPal <[email protected]> Co-authored-by: Aman Gupta <[email protected]> Co-authored-by: Chenguang Li <[email protected]> Co-authored-by: Aldehir Rojas <[email protected]> Co-authored-by: Sigbjørn Skjæret <[email protected]> Co-authored-by: Sam Malayek <[email protected]>

Since pipeline parallelism increases memory usage, if the compute buffer allocation fails we can try to disable it before failing the context creation.
