> Project: Hadoop Map/Reduce

>
> Tasks launched by GridMix3 should incrementally and adaptively simulate load (I/O, CPU, memory, etc.) rather than doing
> everything upfront and then sleeping. This helps in evening out the load when fine-grained information from the original
> Task is not available and greater accuracy when it is.
> By "incremental" I mean having several iterations corresponding to appropriate phases/time-slices. By "adaptive" I mean
> taking the existing load into account before inflicting additional load to meet a target load (we are unlikely to achieve
> 100% fidelity as we overshoot or undershoot with each iteration).
