Migrating Legacy Applications to Emerging Hardware

SESSION: Migrating Legacy Applications to Emerging Hardware

EVENT TYPE: Birds of a Feather

EVENT TAG(S): Programming Systems, Architectures

TIME: 12:15PM - 1:15PM

SESSION LEADER(S):Sriram Swaminarayan, Andy Herdman, Michael W. Glass

ROOM:Ballroom E

ABSTRACT:

Software always lives longer than expected. Hardware changes over this lifetime are hard to ignore. Current hardware presents software written in the 1990s with tremendous on-node parallelism such that an MPI-only model is insufficient. Modifying these large, complex, MPI-only applications to run well on current hardware require extensive and invasive changes. Further, new programming models for exploiting the on-node parallelism typically assume a start-from-scratch-and-application-wide approach making them difficult to use. In this BoF a panel of experts will discuss migration paths that will allow legacy applications to perform better on current and future hardware.
