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.
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
Inline PTX Assembly in CUDA - NVIDIA Documentation Hub
Jan 21, 2025 · 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:

Jan 21, 2025 · PTX Compiler APIs. The User guide to PTX Compiler APIs. 1. Introduction The PTX Compiler APIs are a set of APIs which can be used to compile a PTX program into GPU assembly code. The APIs accept PTX programs in character string form and create handles to the compiler that can be used to obtain the GPU assembly code.
1. Blackwell Architecture Compatibility - NVIDIA Documentation Hub
Jan 22, 2025 · Depending on the version of the CUDA Toolkit used for building the application, it can be built to include PTX and/or native cubin for the Blackwell architecture. Although it is enough to just include PTX, including native cubin is can avoid the need to JIT compile the PTX at runtime. 2. 1.4.1. Building Applications Using CUDA Toolkit 12.7 or ...
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. 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.
