This repository contains a collection of related software for the
interception of CUDA API calls. For the moment, it also contains
harmonv, a set of tools for manipulation of NVIDIA fat binaries
among other things.
The generator directory contains a set of utilities for the
automatic generation of library interposers from header files. These
can then be used through the LD_PRELOAD mechanism to intercept API
calls to shared libraries.
The libcuda and libcuda-rt contain examples of how the generator
tools are used to generate interposers for the CUDA Device API and the
CUDA Runtime API respectively.
The blobstore directory contains a library that can be used by
interposers to store large blobs of binary data in a SQLite3 database.
The arghelper directory contains a utility to parse arguments passed
to CUDA kernels when they are launched, converting them to blobs that
can then be stored in the trace.
The harmonv directory is not directly linked to the interposition
generation tools, but is often used by them.
Its primary purpose is to provide substitutions for tools like
NVIDIA's cuobjdump, but through a Python library interface.
