fabric.submit Fabric Instructions

fabric.submit{.submitop};

Submits prior fabric operations issued by the current thread.

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.

Syntax Forms

One mnemonic covers many type / state-space / scope / modifier combinations - each row below is an independently valid form.

Description

Submits prior fabric operations issued by the current thread. For any thread to observe completion of fabric operations via an mbarrier object, the issuing thread is required to submit those operations before the barrier phase tracking these operations advances. Otherwise, the behavior is undefined. See Life of a Fabric Operation. If.op_restrict::fetching is specified, then only prior fabric.try_get and fabric.try_pullred operations issued by the current thread are submitted. Otherwise, all prior fabric operations issued by the current thread are submitted. This operation has no effect on fabric operations that have already been submitted.

Examples

fabric.submit.op_restrict::fetching;

fabric.submit;
