Seismic Imaging on the Intel Paragon
A key to reducing the risks and costs of associated with oil and gas exploration is the fast, accurate imaging of complex geologies, such as salt domes in the Gulf of Mexico and overthrust regions in U.S. onshore regions. Prestack depth migration generally yields the most accurate images, and one approach to this is to solve the scalar wave equation using nite diierences. Current industry compu...
متن کاملMaple on the Intel Paragon
We ported the computer algebra system Maple V to the Intel Paragon, a massively parallel, distributed memory machine. In order to take advantage of the parallel architecture, we extended the Maple kernel with a set of message passing primitives based on the Paragon's native message passing library. Using these primitives, we implemented a parallel version of Karatsuba multiplication for univari...
متن کاملFirst Experiences with High Performance Fortran on the Intel Paragon
Recently the rst commercial HPF subset compilers have appeared. This paper reports on our experiences with the APR XHPF compiler, version 1.2, for the Intel Paragon. At this stage, we do not expect optimum performance of our HPF programs, even though performance will eventually be of paramount importance for the acceptance of HPF. Instead, the objective is to study how to convert large F77 prog...
متن کاملThree-dimensional Compressible Rayleigh-taylor Instability on the Intel Paragon
Results are described of computations of 3D compressible Rayleigh-Taylor instability done on the 512 node Intel Paragon at Caltech. The code uses Flux Corrected Transport to solve the Euler equations of hy-drodynamics. The Rayleigh-Taylor instability is an important mixing mechanism in a variety of ows such as supernovae and inertial con-nement fusion. Results of the simulations have been chara...
متن کاملBalancing contention and synchronization on the Intel Paragon
The Intel Paragon is a mesh-connected distributed memory parallel computer. It uses an oblivious and deterministic message routing algorithm: this permits us to develop highly optimized schedules for frequently needed communication patterns. The complete exchange is one such pattern. Several approaches are available for carrying it out on the mesh. We study an algorithm developed by Scott. This...
