* [example] batched-bench "segmentation fault" When `llama-batched-bench` is invoked _without_ setting `-npl`, "number of parallel prompts", it segfaults. The segfault is caused by invoking `max_element()` on a zero-length vector, `n_pl` This commit addresses that by first checking to see if the number of parallel prompts is zero, and if so sets the maximum sequence size to 1; otherwise, sets it to the original, the result of `max_element()`. Fixes, when running `lldb build/bin/llama-batched-bench -- -m models/Meta-Llama-3-8B.gguf` ``` * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x0) frame #0: 0x000000010000366c llama-batched-bench`main(argc=3, argv=0x000000016fdff268) at batched-bench.cpp:72:28 69 llama_context_params ctx_params = llama_context_params_from_gpt_params(params); 70 71 // ensure enough sequences are available -> 72 ctx_params.n_seq_max = *std::max_element(n_pl.begin(), n_pl.end()); ``` * Update examples/batched-bench/batched-bench.cpp Co-authored-by: compilade <git@compilade.net> --------- Co-authored-by: Georgi Gerganov <ggerganov@gmail.com> Co-authored-by: compilade <git@compilade.net>

[SYCL] Fix WARP_SIZE=16 bug of Intel GPU (ggml-org#8266)
* fix group_norm ut
Fix issue in above PR:
fix norm() nullptr lead to crash on iGPU.
use WARP_32_SIZE replace QK_WARP_SIZE
optimize dmmv.cpp for iGPU.
add sycl_hw.cpp to detect Hardware info.
