Linux OS Jitter Measurements at Large Node Counts using a BlueGene/L
- ORNL
- IBM T. J. Watson Research Center
We present experimental results for a coordinated scheduling implementation of the Linux operating system. Results were collected on an IBM Blue Gene/L machine at scales up to 16K nodes. Our results indicate coordinated scheduling was able to provide a dramatic improvement in scaling performance for two applications characterized as bulk synchronous parallel programs.
