performance loss in large parallel machines caused by small, unsynchronized operating system activities that delay individual nodes and stall collective operations.

In parallel computing, operating system noise refers to performance loss in large parallel machines caused by small, unsynchronized operating system activities that delay individual nodes and stall collective operations. This meaning comes from Petrini (2003) in Proceedings of the 2003 ACM/IEEE conference on Supercomputing.[1]
