This webinar aims to introduce FLOW-3D/MP to engineers working on large simulation problems, where scaling up to take advantage of multi-core clusters can considerably shorten simulation runtimes.

FLOW-3D/MP version 5.0 enables engineers to take advantage of the scaling potential of the software on multi-core 64-bit clusters. FLOW-3D users with access to Linux HPC clusters can obtain simulation results for their transient free-surface problems by using FLOW-3D/MP. Version 5.0 is a hybrid parallel version of FLOW-3D v10.1 and uses Message Passing Interface (MPI) and OpenMP to achieve parallelization. The OpenMP paradigm is based on shared memory architecture (fine-grained or loop-level parallelism) while MPI is based on a distributed memory, domain decomposition paradigm (coarse-grained). The physical domain is decomposed into blocks or MPI domains, which are then associated with MPI processes and assigned to nodes on a cluster. Within nodes, the MPI processes spawn threads and perform multi-threaded calculations using OpenMP directives. The physical models and numerical methods of FLOW-3D/MP v5.0 are based on FLOW-3D v10.1.
