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

Asynchronously copies size bytes from [src] to destination fabric handle [dstLeId, dstDataOff], where dstLeId is a 32-bit unsigned value denoting the logical endpoint identifier, and dstDataOff is a 64-bit unsigned value denoting the base offset of the resource to access within the logical endpoint associated with dstLeId. The size operand is 32 bits and specifies the number of bytes to be copied. It must be a multiple of 16; otherwise, the behavior is undefined. The range [src, src + size - 1] must be in bounds of the source memory space. (see the official PTX ISA docs for the full description)
