This paper introduces FLEX-MPI, a novel runtime approach for the dynamic load balancing
of MPI-based SPMD applications running on heterogeneous platforms in the presence of …

Applications that use large data sets frequently exhibit poor performance because the size of
their working set exceeds the real memory, causing excess page faults, and ultimately …

An efficient parallel algorithm is presented for computing selected components of A^-1
where A is a structured symmetric sparse matrix. Calculations of this type are useful for …

Performance analysis is vital for optimizing the execution of high performance computing
applications. Today different techniques for gathering, processing, and analyzing application …

PAPI is a cross-platform interface to the hardware performance counters available on most
modern microprocessors. These counters exist as a small set of registers that count events …

This research defines and analyzes a methodology for deriving a performance model for
SPMD hybrid parallel applications. Hybrid parallelism combines sharedmemory and …
