You need something like a GPS (run of the mill is good to 10-50 ns) or IEEE-1588 timing distribution (Precision Time Protocol)

If you have accurate 1pps to appropriate hardware on your nodes, then getting (much better) than sub-microsecond timing is more a matter of software than the hardware.

Can it do better than millisecond time stamps yet? My network stuff needs nanoseconds or better...

I am interested to see if any one is already using ELK for HPC related logs. i would like to know more about what metrics, information, reports they are generating and logstash patterns, filters, any groks used. I have just started working on this starting with the configuration management side of systems, however i see huge potential for people who can not afford to have splunk, I am thinking scheduler, interconnect, GPFS, provisioning, system logs, job tractability, metrics from accounting file, profiling, better failure management and visualisation.

kind regards
