server : move chat-template thinking probe inside the init try/catch (#24093 )

A model whose chat template parses at init but fails parser generation at apply time (e.g. uses {% call %}) throws std::invalid_argument from common_chat_templates_support_enable_thinking(), which ran outside the try/catch guarding common_chat_templates_init(). The throw was uncaught and llama-cli aborted (SIGABRT) instead of failing to load. Moved the probe inside that try/catch so an apply-time error fails load the same way an init parse error does.

Jesse LaRose	82fce65d8b	server : move chat-template thinking probe inside the init try/catch (#24093 ) A model whose chat template parses at init but fails parser generation at apply time (e.g. uses {% call %}) throws std::invalid_argument from common_chat_templates_support_enable_thinking(), which ran outside the try/catch guarding common_chat_templates_init(). The throw was uncaught and llama-cli aborted (SIGABRT) instead of failing to load. Moved the probe inside that try/catch so an apply-time error fails load the same way an init parse error does.

RapidMark	ccb0c34223	ggml-hip: enable -funsafe-math-optimizations (#24668 ) CUDA is compiled with fast math and AMD/HIP is not — this flag lets AMD use fast math too. We can't use -ffast-math: it implies -ffinite-math-only, which won't compile (ggml uses INFINITY for masking) and produces NaNs. -funsafe-math-optimizations gives the speedup without the NaN problems.

Pascal	2021515a1a	cuda: align snake fusion matcher with the other backends (#25460 ) * cuda: fix snake fusion type predicate, a and inv_b are F32 The matcher required a->type == x->type while launch_snake reads both as const float , matching the CPU and Metal contract where a and inv_b stay F32. F16/BF16 chains never fused and fell back to the naive path, and a hypothetical all F16 chain would have read F16 bits as float. Aligns the predicate and the comment with ggml-cpu.c cuda: reject snake fusion on non-contiguous operands The kernel reads x[idx] and a[c] / inv_b[c] linearly, so a non-contiguous view passing the matcher would silently read wrong data. Mirror the contiguity guard already present in the CPU, Vulkan and Metal matchers.	2026-07-09 11:00:06 +03:00

Hongqiang Wang	92366df30d	opencl: Q6_K GEMM/GEMV fix for ne01 of weights that are not multiples of 128. (#25464 ) * opencl: fix garbled output for Q6_K weights with ne01 % 128 != 0 on Adreno Observed with granite-3.1-3b-a800m-instruct, whose vocab is an odd number. Route Q6_K dense mul_mat with ne01 % 128 != 0 off the noshuffle path: decode (ne1==1) uses the correct flat GEMV and the matching GEMM (ne1>1) falls back to CPU (the flat convert has no verified small-batch GEMM kernel for these shapes). All standard hidden/FFN/vocab dims are multiples of 128 and keep the noshuffle path. * opencl: reserve alignment slack for the SOA subbuffer carve in alloc size set_tensor carves quantized weights into per-component subbuffers (d/q, ql/qh/s/d, ...) whose origins are each rounded up to the device base address alignment. When a component's size is not a multiple of the alignment, the carve extends past ggml_nbytes(tensor) and the last subbuffer overlaps the next tensor in the pool -- e.g. q6_K [1536, 49155]: size_s = 4915596 ends 32 bytes past a 128-byte boundary, so the d subbuffer ends 96 bytes past the tensor's allocation, and whichever of the two neighboring tensors is uploaded last silently corrupts the other (here: the last vocab rows' block scales). This affects any quant type whose component sizes can be misaligned, on any shape with ne01 not a multiple of the alignment granularity; standard power-of-two dims are unaffected. Implement get_alloc_size for the OpenCL buffer type and reserve the worst-case carve slack (4 aligned gaps; 5 components max, q5_K) for quantized tensors. Costs at most 512 bytes per quantized tensor at the observed 128-byte alignment. opencl: use lm based q6_k mm when ne1 is not multiple of 128 --------- Co-authored-by: Li He <lih@qti.qualcomm.com>	2026-07-08 15:52:21 -07:00

Hongqiang Wang	167d057604	opencl: ragged-tile MoE prefill FP16 GEMM optimization (skip padded expert tiles) (#25433 ) * opencl: ragged-tile MoE prefill GEMM (skip padded expert tiles) The MoE prefill GEMM groups tokens into TILESIZE_N=32 per-expert tiles; at low tokens-per-expert most tiles are mostly padding. When a tile's upper 16 slots are all padding (router index 0xFFFFFFFF), skip the second dotx16_reduce8 half. Numerically identical (skipped lanes are padding). Applied to all eight _f32_ns MoE GEMMs; default on, opt out with GGML_OPENCL_MOE_RAGGED_FP16=0. opencl: quarter-granularity ragged MoE tile-skip (8-col skip-groups) Replace the two half-tile dotx16_reduce8 calls in the 8 _f32_ns MoE GEMMs with four dotx8_reduce4 (8-column) calls, skipping each empty trailing skip-group independently. Padding is always trailing, so the kernel rounds the valid count up to the skip granularity and skips fully-padding groups. Byte-identical to the non-skipped path. New env GGML_OPENCL_MOE_RAGGED_GRAN={8,16,32} (quarter/half/ off); default quarter. opencl: move ragged moe env var in cl_init --------- Co-authored-by: Li He <lih@qti.qualcomm.com>	2026-07-08 09:44:55 -07:00
