Pure Data (also known as Pd) is a real-time graphical programming environment for audio and graphics processing.

PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It employs the MPI standard for all message-passing communication.

Opencl-clang is a thin wrapper library around clang. It has an OpenCL-oriented API and is capable of compiling OpenCL C kernels to SPIR-V modules.

Pure Data (also known as Pd) is a real-time graphical programming environment for audio and graphics processing. Pd's audio functions are built-in; graphical computations require separate packages such as gem (Graphics Environment for Multimedia) or pd-pdp (Pd Packet).

This tool makes it easy to publish files, clipboards, screenshots, and photo galleries online with a single command. It's somewhat messy but it does its job well.
