Product Overview

GNU Parallel

Description: GNU Parallel is a shell tool for Linux and UNIX-like operating systems that allows commands to be run in parallel. It can speed up tasks that can be parallelized by distributing work across multiple CPUs or computers.

HTCondor

Description: HTCondor is an open-source high-throughput computing software framework for coarse-grained distributed parallelization of computationally intensive tasks. It can manage a cluster of computers to harness otherwise unused CPU and GPU cycles for scientific research.
