…with split_alignment > 1
* Modify the static solver so that each segment of input_split_size is divisible by the same number * modify chunk logic in static solver
* add merge_with_split_alignment method in AttnRanges * support split alignment in dynamic solver
* relaxed the buffer size up to INT_MAX limit for internode * tested over INT_MAX buffer size in exp/grpcoll tests * minor fixed * added docstring for config funcs * added minimium num bytes check for native grpcoll * fixed tma bytes and num warps for internode cache notify kernel * raised up default num_rdma_bytes * further fixed internode cache notify kernel for group reduce * removed the temp debug code to make benchmark mask split-aligned
* added num_heads_q,kv,group to comm meta for dynamic solver; added seperate split alignment for kv/qo * added num_heads_q/kv to comm meta for dynamic solver * supported split alignment varying from dtype * added native_grpcoll_split_alignment to test_pipeline/test_pipeline_sdpa * tested through dynamic split alignment for pipeline ut; added world size offset for seed * added some comments * added MAGI_ATTENTION_NATIVE_GRPCOLL_SPLIT_ALIGNMENT to docs
* updated and polished api for required num_heads_q, num_heads_kv, head_dim * adjusted the calls in ut for updated APIs * adjusted the calls in examples for updated APIs * adjusted the calls in exps for updated APIs * adjusted the calls in docs and readme for updated APIs, as well as deleting the magi_attn_varlen_dipatch and magi_attn_flex_dispatch deprecated APIs * minor updated tests/test_api/test_interface.py * minor updated benchmark dockerfile
* added head dim to comm meta * supported auto split alignment w/o varying from dtypes * minor updated repr and utils * added strategy for calc_split_alignment
* updated run_grpcoll_test script for B300 * updated benchmark conf and script for blackwell * added script to install custom nvshmem-3.4.5 on b300 roce
* support save last stage for bwd overlap policy * rename backward_overlap_policy to backward_hide_tail_reduce * rename several params about hide_tail_stage_reduce
* fixed missing split_alignment_kv for dist_attn_solver * fixed missing arg for _hide_tail_stage_reduce_backward
