Place: 446 Room, ICT, CAS
Speaker: Dr. Pavan Balaji

Abstract: 
With the current push towards massive-scale computing systems that comprise millions or billions of processing elements, faults are quickly becoming a common place for scientific simulations. In this talk, I'll describe some of the recent efforts within MPI, which is the most commonly used model for parallel programming, with respect to fault resilience. Specifically, I'll discuss some traditional transparent fault resilience techniques, upcoming features in MPI-3 to deal with fault tolerance, application-level fault tolerance techniques, and fault coordination techniques between multiple software components. I'll also briefly talk about "silent faults" which is an increasing concern in massive-scale systems, and is a fundamental deviation from the current model where we assume that faults are identifiable errors.
