Encoding

PTX is a virtual instruction set. It has no single, stable native binary encoding - the compiler lowers this instruction to different native machine code depending on the selected NVIDIA target architecture (compute capability). This page intentionally shows no bit-diagram; see the target/version requirements below for what governs how this instruction compiles.

Description

cp.async.bulk.commit_group instruction creates a new per-thread bulk async-group and batches all prior cp{.reduce}.async.bulk{.prefetch}{.tensor} instructions satisfying the following conditions into the new bulk async-group: The prior cp{.reduce}.async.bulk{.prefetch}{.tensor} instructions use bulk_group based completion mechanism, and They are initiated by the executing thread but not committed to any bulk async-group. If there are no uncommitted cp{.reduce}.async.bulk{.prefetch}{.tensor} instructions then cp.async.bulk.commit_group results in an empty bulk async-group. An executing thread can wait for the completion of all cp{.reduce}.async.bulk{.prefetch}{. (see the official PTX ISA docs for the full description)
