Accelerate simulations with the Nvidia Quadro K6000

Nvidia® recently released a new high-end graphics card in the Kepler series, the Nvidia Quadro® K6000. This card has a large amount of onboard RAM (12 GB), making it very suitable for large and demanding tasks. Starting with CST STUDIO SUITE 2013 Service Pack 4, all solvers in CST STUDIO SUITE with GPU computing acceleration now support the Quadro K6000.

To test its performance, we carried out a series of simulation benchmarks with a Quadro K6000, comparing it to both to another Nvidia GPU card, the Nvidia Tesla® K20c, and to an equivalent system with two Xeon E5-2650 CPUs.

As shown in the graph below, both GPU cards offered a significant benefit when compared to CPU simulation. However, for larger models, with tens of millions of mesh cells, the Quadro K6000 showed a performance improvement of between 30% and 35% compared to the Tesla K20c, giving a four-fold speedup compared to the CPU simulation. The benchmarks were performed on a ProViz W60 workstation with the time domain solver in CST STUDIO SUITE 2013. The hardware for this benchmark was kindly provided by CADnetwork.

The Bluetooth Challenge at LAPC

As part of the annual Loughborough Antennas & Propagation Conference (LAPC), our friends at Antenna Magus will be hosting the ‘Bluetooth Challenge’ at booth D2.

And what is the ‘Bluetooth Challenge’ you ask?

Using Antenna Magus software, attendees are invited to design a suitable antenna that extends the (directional) bluetooth range. Using the provided tools and basic materials, participants can then build the antenna right there at the booth.

A winner will be chosen using the bluetooth audio streaming range-test.

If you’re looking to have an edge in the Bluetooth Challenge next week, have a look at these Antenna Magus designs … and remember to visit booth D2 at LAPC!

Technical Application Webinar Series

We’ve already broadcast more than half of the CST Webinar Series 2013, but we still have a range of topics to explore, from wireless power transfer to traveling wave tube design, and more.

Make sure you mark your calendars and register for the weekly webinars in November to find out how electromagnetic simulation can help you in your daily work.

November 7: Wireless Power Transfer and Microwave Energy Harvesting
This webinar will consist of two parts. The first part is a review of low frequency power transfer in two categories: short range-inductive charging and powering of electronic devices and electric vehicles, and mid-range power transfer through coupled resonant circuits. The second part of the webinar is concerned with wireless energy transfer over longer distances, where the far-field transfer of RF energy may be used.

November 14: EMC Simulation in the Design Flow of Modern Electronics
In this webinar we will show several examples of EMC countermeasures in modern electronics and good practices for implementing them. We will also demonstrate how simulation can predict the EMC performance of typical components like PCBs, enclosures and cables, and compare the simulation results to measurements performed on physical implementations of the structures.

November 21: Traveling Wave Tube Design with Simulation
This webinar will show how the design of traveling wave tubes can be bolstered by the use of simulation tools and high-performance computing, beginning with adjusting the geometry of the SWS such that beam and phase velocity of the wave are synchronized.

November 26: Simulating Dielectric and Conductor Loss Components Including the Influence of Trace Edge and Surface Roughness Topography
Dielectric and conductor loss components require careful material parameterization and structure set up. This webinar will give an overview of the parameterizations and set up, including the trace cross-section shape influence on conductor loss.

As our webinar service provider is unable to support access via mobile devices, please ensure you use a desktop or laptop computer to register and attend the event.
