Plurix is a Unix-like operating system developed in Brazil in the early 1980s at the Electronic Computing Center (NCE) of the Federal University of Rio de Janeiro. Its researchers had returned from postgraduate courses in the United States and tried without success to license the Unix source code from AT&T. In 1982 a team led by Newton Faller began writing an alternative system, using Unix Version 7 as the reference, and by 1985 Plurix was running on the Pegasus 32-X, a shared-memory multiprocessor computer also designed at NCE. It was licensed to some Brazilian companies in 1988. The project belonged to the protected Brazilian computer market of the period, in which several local firms and universities built their own Unix-like systems, and it ended when that protection was repealed. It later led to two related projects at NCE, Mulplix for the MULTIPLUS parallel machine and the real-time system Tropix. A separate German operating system for PC clusters shares the Plurix name.
