How tolerable is OS Jitter during hft and high frequency trading?
Given two large-scale, massively parallel, distributed memory systems, one with twice the core-count as the other, would a +/-20% level of OS Jitter in the larger system be quantifiably more cost-effective or productive (insert your criteria here) than the smaller system with +/-5% OS Jitter?
For a definition of OS Jitter, I defer to Bill Buros, et al on
Here we define “OS Jitter” as interference that an application (be it a process or a thread) experiences. This can prevent the application from obtaining nearly identical predictable and repeatable results from a run-time completion perspective (ie: how long the task takes to complete).
NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
