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...

System resource accounting in a heterogeneous distributed computing environment

The accounting tool, S A T , is designed to perform system resource accounting in a large, heterogeneous, distributed computing environment. This paper Hescribes the design,implementation and operation of SAT. The tool as currently operational at Supercomputer Education And Research Centre (SERC) at Indian Institute Of Sceince. SERC is a large academic computing centre catering to the computing...

A Mobile and Fog-based Computing Method to Execute Smart Device Applications in a Secure Environment

With the rapid growth of smart device and Internet of things applications, the volume of communication and data in networks have increased. Due to the network lag and massive demands, centralized and traditional cloud computing architecture are not accountable to the high users' demands and not proper for execution of delay-sensitive and real time applications. To resolve these challenges, we p...

Secure Distributed Computing in a Commercial Environment

The recent successes of a number of nonprofit computing projects distributed over the Internet has generated intense interest in the potential commercial applications of distributed computing. In a commercial setting, where participants might be paid for their contributions, it is crucial to define a security framework to address the threat of cheating and offer guarantees that the computation ...
