MPICH

MPICH is an open-source software library that enables multiple computers or processors to work together as a single system to solve large, complex problems efficiently. It manages the communication and coordination between different machines, allowing them to share information quickly and seamlessly. Commonly used in scientific research and high-performance computing, MPICH helps applications run faster by splitting tasks across multiple processors, making it possible to tackle computations that would be too big or slow for a single machine.
