1. Introduction — PTX ISA 8.7 documentation
Sep 7, 2010 · PTX programs are a collection of text source modules (files). PTX source modules have an assembly-language style syntax with instruction operation codes and operands. Pseudo-operations specify symbol and addressing management. The ptxas optimizing backend compiler optimizes and assembles PTX source modules to produce corresponding binary object ...
1. Introduction — PTX Interoperability 12.8 documentation
PTX is a low-level parallel-thread-execution virtual machine and ISA (Instruction Set Architecture). PTX can be output from multiple tools or written directly by developers. PTX is meant to be GPU-architecture independent, so that the same code can be reused for different GPU architectures.
Inline PTX Assembly in CUDA - NVIDIA Documentation Hub
For more information on the PTX ISA, refer to the latest version of the PTX ISA reference document. This application note describes how to inline PTX assembly language statements into CUDA code. 1.1. Assembler (ASM) Statements Assembler statements, asm(), provide a way to insert arbitrary PTX code into your CUDA program. A simple example is:
PTX ISA :: CUDA Toolkit Documentation
Jun 21, 2018 · PTX is case sensitive and uses lowercase for keywords. Each PTX module must begin with a .version directive specifying the PTX language version, followed by a .target directive specifying the target architecture assumed. See PTX Module Directives for a more information on these directives

PTX and SASS Assembly Debugging - NVIDIA Documentation Hub
PTX is a low-level parallel-thread execution virtual machine and instruction set architecture (ISA). PTX exposes the GPU as a parallel computing device. In addition, PTX provides a stable programming model and instruction set for general purpose parallel programming, and is designed to be efficient on NVIDIA GPUs.
1. Volta Compatibility — Volta Compatibility Guide 12.8 …
The CUDA driver will cache the cubins generated as a result of the PTX JIT, so this is mostly a one-time cost for a given user, but it is time best avoided whenever possible. PTX JIT-compiled kernels often cannot take advantage of architectural features of newer GPUs, meaning that native-compiled code may be faster or of greater accuracy. 1.4.1.
1. NVIDIA Ampere GPU Architecture Compatibility
Jan 21, 2025 · For example, PTX code generated for compute capability 7.x is supported to run on compute capability 7.x or any higher revision (major or minor), including compute capability 8.x. Therefore although it is optional, it is recommended that all applications should include PTX of the kernels to ensure forward-compatibility.
