Heterogeneous Computing

Heterogeneous Computing

Heterogeneous computing is a set of techniques enabling the use of diverse computational capabilities for the execution of a meta-task [2, 4, 7]. A meta-task is an arbitrary collection of independent (non-communicating) tasks with a variety of computational needs, which are to be executed during a given interval of time (e.g., a day). Some tasks may be decomposable into one or more communicatin...

Heterogeneous Distributed Computing

Distributed Computing in a Heterogeneous Computing Environment

Distributed computing is a means to overcome the limitations of single computing systems. In this paper we describe how clusters of heterogeneous supercomputers can be used to run a single application or a set of applications. We concentrate on the communication problem in such a connguration and present a software library called PACX-MPI that was developed to allow a single system image from t...

Tiling for Heterogeneous Computing Platforms Ecole Normale Supérieure De Lyon Tiling for Heterogeneous Computing Platforms Tiling for Heterogeneous Computing Platforms

In the framework of fully permutable loops tiling has been extensively studied as a source to source program transformation However little work has been devoted to the mapping and scheduling of the tiles on physical processors Moreover targeting hetero geneous computing platforms has to the best of our knowledge never been considered In this paper we extend tiling techniques to the context of l...

Hence: a Heterogeneous Network Computing Environment Hence: a Heterogeneous Network Computing Environment Hence: a Heterogeneous Network Computing Environment

Network computing seeks to utilize the aggregate resources of many networked computers to solve a single problem. In so doing it is often possible to obtain supercomputer performance from an inexpensive local area network. The drawback is that network computing is complicated and error prone when done by hand, especially if the computers have diierent operating systems and data formats and are ...
