Low-level parallel thread execution virtual machine and instruction set architecture
Parallel Thread Execution (PTX or NVPTX[1]) is a low-level parallel thread execution virtual machine and instruction set architecture used in Nvidia's CUDA programming environment. The NVCC compiler translates code written in CUDA, a C++-like language, into PTX instructions (an assembly language represented as ASCII text), and the graphics driver contains a compiler which translates the PTX instructions into the executable binary code[2] which can be run on the processing cores of Nvidia GPUs. The GNU Compiler Collection also has basic ability for PTX generation in the context of OpenMP offloading.[3] Inline PTX assembly can be used in CUDA.[4]
