HPC capabilities for CST MICROWAVE STUDIO 2011

A well known trend in microwave & RF device design is the increase in device complexity, with an accompanying decrease of time allowance for the R&D process. Electromagnetic simulation can reduce the number of prototyping cycles, but the increase in simulation model size still represents a special challenge. This is addressed by high performance computing (HPC) techniques The CST Simulation Acceleration scheme provides customers with a choice of HPC features. Notably the GPU computing capability has proven to be a success, since significant speed-ups can be achieved with a very reasonable investment. The CST MICROWAVE STUDIO 2011 transient solver now supports NVIDIA® Tesla™ 2o series (codename Fermi). Employing the new generation of GPUs, results in a remarkable increase in performance.

Cluster computing is the best option for exceptionally large or complex models. Communication between nodes is becoming a critical bottleneck, in particular if the nodes are equipped with GPUs. CST’s MPI solution now supports Infiniband, a high throughput, low latency interconnection that helps ensure the solution’s scalability. Besides the established solutions for the CST MWS transient and direct Integral Equation solver, MPI based parallelization is now also available for the Integral equation solver with MLFMM. This solver is dedicated to the simulation of electrically very large problems. CST STUDIO SUITE comes with a simple job-queuing system: the Job Control Center. In more complex computing environments, sophisticated external resource management or job-queuing systems might be required or are already operational. CST STUDIO SUITE version 2011 can be integrated easily with free or commercial systems such as the Load Sharing Facility (LSF) or the Oracle Grid Engine (OGE).
