MONITORING SYSTEM NOISES IN PARALLEL COMPUTER SYSTEMS

摘要

Various embodiments monitor system noise in a parallel computing system. In one embodiment, at least one set of system noise data is stored in a shared buffer during a first computation interval. The set of system noise data is detected during the first computation interval and is associated with at least one parallel thread in a plurality of parallel threads. Each thread in the plurality of parallel threads is a thread of a program. The set of system noise data is filtered during a second computation interval based on at least one filtering condition creating a filtered set of system noise data. The filtered set of system noise data is then stored.

1. A method for monitoring system noise in a parallel computing system, the method comprising:
storing, during a first computation interval, at least one set of system noise data in a buffer, wherein the set of system noise data is detected during the first computation interval and is associated with at least one thread in a plurality of threads, and wherein each thread in the plurality of threads is a thread of a program; filtering, during a second computation interval, the set of system noise data based on at least one filtering condition, the filtering creating a filtered set of system noise data; and storing the filtered set of system noise data.
