描述

定义并且实现PTO-COMM-ISA，Tile粒度的多卡P2P/同步/P2MP操作 定义统一的抽象，并且提供实现。

Point-to-Point Communication (Synchronous)

• TPUT: docs/isa/comm/TPUT.md - Remote write (GM → UB → GM)
• TGET: docs/isa/comm/TGET.md - Remote read (GM → UB → GM)

Signal-Based Synchronization

• TNOTIFY: docs/isa/comm/TNOTIFY.md - Send notification to remote NPU
• TWAIT: docs/isa/comm/TWAIT.md - Blocking wait for signal condition
• TTEST: docs/isa/comm/TTEST.md - Non-blocking test signal condition

Collective Communication

• TGATHER: docs/isa/comm/TGATHER.md - Gather data from all ranks
• TSCATTER: docs/isa/comm/TSCATTER.md - Scatter data to all ranks
• TREDUCE: docs/isa/comm/TREDUCE.md - Reduce data from all ranks to local
• TBROADCAST: docs/isa/comm/TBROADCAST.md - Broadcast from current NPU to all ranks

测试

1. 安装cann-shmem 并且set执行环境 https://gitcode.com/cann/shmem?source_module=search_result_repo
2. bash tests/run_comm_test.sh 可以运行全部 comm-isa 测试用例
