We prove that with high probability a skip graph contains a 4-regular expander as a subgraph, and estimate the quality of the expansion via simulations. As a consequence skip grap...
Commercial Off-The-Shelf (COTS) software products are increasingly used as software components in large-scale systems. We had proposed an approach for distributed COTS software int...
In this work we present the runtime architecture of the OMPi OpenMP compiler. OMPi is a source-to-source C translator featuring a portable, modular and extensible runtime system. ...

With the ever-increasing numbers of cores per node on HPC systems, applications are increasingly using threads to exploit the shared memory within a node, combined with MPI across ...
Efficient and robust metacomputing requires the decomposition of complex jobs into tasks that must be scheduled on distributed processing nodes. There are various ways of creating...
