Parallel numerical simulation for a super large-scale compositional reservoir

Parallel Compositional Reservoir Simulation on a Cluster of Pcs

We have ported a fully implicit EOS (equation-of-state) compositional parallel reservoir simulator to a cluster of PCs. We report on the performance of the cluster, both in terms of scalability and in absolute performance relative to an IBM SP. The simulator scales well through 16 processors, with each run taking less than twice as long as the comparable run on the SP.

Large Scale Parallel Numerical Integration

We present and analyze strategies which can be used for the parallel computation of large numbers of integrals which may be of diierent levels of diiculty. Paralleliza-tion on the integral level, which is generally used for large numbers of integrals, is combined with parallelization on the subregion level, which enables handling local integration diiculties within individual problems. This res...

An Efficient and Effective Nonlinear Solver in a Parallel Software for Large Scale Petroleum Reservoir Simulation

We study a parallel Newton-Krylov-Schwarz (NKS) based algorithm for solving large sparse systems resulting from a fully implicit discretization of partial differential equations arising from petroleum reservoir simulations. Our NKS algorithm is designed by combining an inexact Newton method with a rank-2 updated quasi-Newton method. In order to improve the computational efficiency, both DDM and...

Large Scale Numerical Simulation for Superfluid Turbulence

Large scale numerical simulation of quantum turbulence is performed by using 3-D time-dependent Gross-Pitaevskii equation. The energy spectrum obeying Kolmogorov law and large scale self-similar structure of quantum vortex tangle are found in a fully developed dumped turbulent state. Width of the inertial range becomes large depending on the system size of the simulation that is consistent with...
