The Partitioned Global Address Space (PGAS) programming model has attracted considerable attention in HPC circles, primarily because it offers application programmers the convenience of globally addressable memory along with the locality control needed for scalability.
The highly ambiguous nature of natural language presents many challenges to researchers who design software to analyze, understand and generate languages that humans use naturally.
Message Passing Interface (MPI) is the dominant parallel computing model on supercomputers today, including petascale systems that are capable of executing one quadrillion operations per second. MPI allows the thousands of nodes in these large clusters to “talk” with one another over high-speed, internal networks, such as
A former British army officer once said, “History is littered with the Wars which everybody knew would never happen.”
In April, physicists working on the ALICE project (short for A Large Ion Collider Experiment) began recording data from collisions within the Large Hadron Collider, operated by the European Laboratory for Nuclear Research (CERN) near Geneva, Switzerland.
In huge tunnels below the Swiss-Franco border, the European Organization for Nuclear Research's Large Hadron Collider (LHC) is operating at half of its peak energy goal of 14 TeV or 'teraelectronvolts.' With the assistance of detectors built into the collider, physicists are searching for answers to questions about the birth of the universe, the existence of alternate dimensions and other key f
A recently developed, evolutionary computation approach offers researchers an alternative approach to search for models that can best explain experimental data derived from applications such as economics. Esmail Bonakdarian, Ph.D., a Franklin University assistant professor of computing sciences and mathematics, leveraged Ohio Supercomputer Center resources to test the underlying algorithm.
The Center for Surveillance Research (CSR), a National Science Foundation Industry/ University Cooperative Research Center, is a collaborative effort by academia, government and industry to conduct pre-competitive research and student training.
Scientific computing is credited for many of the technological breakthroughs of our generation and is used in many fields, ranging from drug discovery and aerospace to weather prediction and seismic analysis. Scientific computation often deals with very large amounts of data, and its algorithms need to compute results from mathematical models.
Supercomputing centers allow astronomers to create extremely sophisticated models that are not feasible to build on desktop systems. However, simulating the multitude of elements involved in these galactic processes remains an enormous challenge.
