Beowulf Cluster Equipped with High-Speed Communication Software

Key words:

PC cluster machine, non-TCP/IP communication, small latency and high throughput, fast C/Fortran compilers

Abstract:

A high performance PC cluster computer installed with Linux operating system and MPI (Message Passing Interface) for interprocessor communication has been constructed using a communication software GAMMA (Genoa Active Message Machine) instead of the standard TCP/IP protocol. Fast C/Fortran compilers have been exploited with the GAMMA communication libraries. This method has resulted in drastic reduction of the communication overhead and significant increase in the computation performance of real application programs including the first-principle molecular dynamics simulation code.
