These interactions cause application-specific states to be spread across many service processes, a problem we identify as state entanglement. ...
State entanglement presents significant challenges to a wide variety of computing goals: fault isolation, fault tolerance, application migration, live update, and application speculation. ...
By profiling fork(), we find that it takes only 1 ms to copy and write to about 10 MB of memory, or 2500 pages. ...

We modify its core to measure performance characteristics, obtaining a system that provides cycle-accurate timings and presents results in the style of gprof, but with absolutely no software overhead. ...
Generic processors, such as ARM and Power PC, are inexpensive, but with respect to a given application, they often overprovision in areas that are unimportant for the application's performance. ...
Based on our knowledge of this application, we next evaluate the application's performance with regard to the memory-subsystem behavior. ...

Plotting these metrics for every single allocation over time gives a new insight into application's memory handling. ...
These issues are already known for a decade, but due to the complexity of software frameworks and billions of allocations for a single job, up until recently no efficient mechanism has been available to ...
The paper shows that all profiled HEP applications suffer significantly from memory churn, meaning that 80% of allocations are smaller than 100 Bytes and about 65% live less than 1 ms. ...
