Jitify

A single-header C++ library for simplifying the use of CUDA Runtime Compilation (NVRTC).

Rationale

Integrating NVRTC into existing and/or templated CUDA code can be tricky. Jitify aims to simplify this process by hiding the complexities behind a simple, high-level interface.

Quick example

const char* program_source = "my_program\n"
    "template\n"
    "__global__\n"
    "void my_kernel(T* data) {\n"
    "    T data0 = data[0];\n"
    "    for( int i=0; i

Compile with: -pthread (not needed if JITIFY_THREAD_SAFE is defined to 0)

Link with: -lcuda -lcudart -lnvrtc

A small utility called stringify is included for converting text files into C string literals, which provides a convenient way to integrate JIT-compiled sources into a build.

Running tests

Tests can be run with the following command:

$ make test

This will automatically download and build the GoogleTest library, which requires CMake to be available on the system.

Documentation

Examples

See jitify_example.cpp for some examples of how to use the library. The Makefile also demonstrates how to use the provided stringify utility.
