Modern computer systems are becoming distributed and heterogeneous by comprising multi-core CPUs, GPUs, and other accelerators. However, to program such systems, the user currently has to use a combination of several programming models (e.g., MPI with OpenCL or CUDA), which is difficult and error-prone. We present dOpenCL (distributed OpenCL) – a uniform approach to programming distributed syst...

Atomic Commitment Protocol (ACP) is an important part for any distributed transaction. ACPs have been proposed for homogeneous and heterogeneous distributed database management systems (DBMS). ACPs designed for these DBMS do not meet the requirement of Grid databases. Homogeneous DBMS are synchronous and tightly coupled while heterogeneous DBMS, like multidatabase systems, requires a top layer ...

Workflows are the structured activities that take place in information systems in typical business environments. These activities frequently involve several database systems, user interfaces, and application programs. Tkaditional database systems do not support workflows 20 any reasonable extent. Usually human beings must intervene to ensure their proper execution. W e have developed an archite...

In this paper, we present a game theoretic framework for obtaining a user-optimal load balancing scheme in heterogeneous distributed systems. We formulate the static load balancing problem in heterogeneous distributed systems as a noncooperative game among users. For the proposed noncooperative load balancing game, we present the structure of the Nash equilibrium. Based on this structure we der...

This paper focuses on studying containment control problem with switching communication graphs of continuous-time heterogeneous multiagent systems where the inputs are constrained in a nonconvex set. A nonlinear projection algorithm is proposed to address problem. We discuss stability and system topologies input constraints under three different conditions. It shown that all agents converge con...

In this paper, we discuss the usual stochastic‎, ‎likelihood ratio, ‎dispersive and convex transform order between two parallel systems with independent heterogeneous extended generalized exponential components. ‎We also establish the usual stochastic order between series systems from two independent heterogeneous extended generalized exponential samples. ‎Finally, ‎we f...
