fabric.wait Fabric Instructions

fabric.wait.sync_restrict::reads;

Fabric-read completion mechanism instruction fabric.wait waits on the local shared memory (.shared::cta ) reads of submitted fabric operations.

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.
PTX ISA Version Introduced PTX ISA 9.3
Minimum Target sm_100

Description

Fabric-read completion mechanism instruction fabric.wait waits on the local shared memory (.shared::cta ) reads of submitted fabric operations. This enables overwriting the shared memory read by these operations before they complete.

Examples

fabric.wait.sync_restrict::reads;
