SSS-PC
SSS-PC is an operating system kernel with powerful scalability and load-balancing capabilities, created in Japan by Takashi MATSUMOTO, a Professor at the University of Tokyo. It has superior functions for clustering, parallel processing and targeting server applications. Linux or Unix applications can be ported to SSS-PC directly. The C language BSD library is used. Instead of TCP/IP, an original protocol called Memory Based Communications Facilities (MBCF) was created. It has a unique scheduling strategy called Free Market Mechanism (FMM).
The OS is meant to be inexpensive, high-performing and built to run as a server for telecommunications systems capable of running 24 hours a day, non-stop. When connected to other servers in a cluster, it brings about powerful concurrent or parallel processing, high speed communication and automatic cluster reconstruction abilities: when one server or processing unit fails, it is detected and other members of The Cluster automatically compensate for the failure.
