Integrative Parallel Programming in HPC
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.
