The multiplication of cores in today's architectures raises the importance of intra-node
communication in modern clusters and their impact on the overall parallel application …

Shared memory is among the most common approaches to implementing message passing
within multicorenodes. However, current shared memory techniques donot scale with …

Multi-/many-core CPU based architectures are seeing widespread adoption due to their
unprecedented compute performance in a small power envelope. With the increasingly …

In this paper, we analyze the spatio-temporal human characteristic of moving silhouettes in
frequency domain, and find key Fourier descriptors that have better discriminatory capability …

Message Passing Interface (MPI) implementations provide a great flexibility to allow users to
arbitrarily bind processes to computing cores to fully exploit clusters of multicore/many-core …

We tackle the difficult problem of summarizing the path/branching structure and value
content of an XML database that comprises both numeric and textual values. We introduce a …

Gemini, the network for the new Cray XE/XK systems, features low latency, high bandwidth
and strong scalability. Its hardware support for remote direct memory access enables …

Adaptive MPI is an implementation of the MPI standard that supports the virtualization of
ranks as user‐level threads, rather than OS processes. In this work, we optimize the …

With the emergence of larger multi-/many-core clusters and new areas of HPC applications,
performance of large message communication is becoming more important. MPI libraries …

Accelerator awareness has become a pressing issue in data movement models, such as
MPI, because of the rapid deployment of systems that utilize accelerators. In our previous …
