Altair RADIOSS Structural Solver Available

By DE Editors

Altair announced its RADIOSS structural solver will support NVIDIA professional GPUs. RADIOSS is a finite element structural solver for linear and non-linear simulations. It is used in the automotive and aerospace industries to maximize structural durability, noise-and-vibration performance, crashworthiness, safety and manufacturability of product designs, according to the company.
The RADIOSS Implicit direct solver is employed in structural analysis and sensitivity calculations, while the RADIOSS Implicit iterative solver is used for solving large engineering models with millions of degrees of freedom.
By offloading the intensive matrix computation from either of these two solvers onto NVIDIA GPUs and using heterogeneous GPU and CPU computing, the solver’s speed can be increased when compared to a multi-core CPU-only approach. This hybrid parallelization, based on message passing interface (MPI) to decompose over multiple GPUs using NVIDIA CUDA and multiple CPU cores with OpenMP parallelism, allows a reduction in solution time. Test results utilizing an NVIDIA Tesla M2090 GPU have demonstrated up to four times faster acceleration  in performance, as compared with the latest six-core CPU running the same simulation.
Official GPU support of RADIOSS will be made available in the next release of HyperWorks.  Certification will include NVIDIA Tesla GPUs for compute servers, as well as certification for NVIDIA Maximus technology that combines NVIDIA Quadro professional graphics with NVIDIA Tesla GPUs in a single desktop workstation. PBS Professional will support the forthcoming NVIDIA Tesla K20 GPU, based on the next-generation NVIDIA Kepler compute architecture.
