Adds support for different options and number of layers per node. The per-node options are implemented as parsing command-line options from a file instead of from the command-line itself. This allows each node to have its own version of this options file. The different number of layers per-node is implemented as a new option, `mpi-layer-split`, that takes a list of percentages. These percentages are used to calculate the range of layers to delegate to each node. The ranges are calculated on the head node and then scattered to the other nodes to maintain a single source of truth.

* [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>
