There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title:
Integrative Parallel Programming in HPC
Abstract:
With the ongoing proliferation of architecture types (distributed memory clusters, shared memory, co-processors) comes a proliferation of of programming modes (message passing, active messages, loop-based and task-based parallelism, new SIMD variants), complicating the life of a scientific programmer. To extract all possible performance, a code often has to rely on using more than one mode of parallelism, making it hard to maintain, hard to port, and far from `future-proof'.
In this talk I will present a new framework for parallel programming, called the `Integrative Model for Parallelism (IMP)'. It is based on an abstract model of parallel computing that unifies existing models, yet is detailed enough to give performance comparable to hand-written codes in these models.
I will give a basic overview of the IMP concepts, show a prototype implementation, and indicate future directions of research.
