The NVIDIA GTC2018 Conference was held March 26-29th at the San Jose Convention Center. This is the 7th year that CertaSIM attended the conference and participated in the technical session. Dr. Mindle, CertaSIM’s Director of Sales & Marketing presented a paper entitled “Multi GPU Parallel Processing with NVLINK”. The presentation is available from CertaSIM and NVIDIA also records the audio from the presentation and makes it available to hear online. GPU technology is at the heart of the IMPETUS Afea Solver® massively parallel processing capabilities and so keeping up with the current GPU hardware is a must for CertaSIM.

The 10th Ground Vehicle Systems Engineering And Technology Symposium (GVSETS) will be held August 7-9, 2018 at the Suburban Collection Showplace in Novi Michigan.

The conference includes participants from DoD, TACOM, Research, Development and Engineering Command (RDECOM), Program Executive Offices (PEOs) for the Army and the Marine Corps for ground vehicles as well as leaders from industry and academia. The trade show has grown considerably over the last 4 years and provides a great venue to meet many of the companies that work with the US Army with regard to ground vehicle development. The overriding tone of the conference is the mission to design and build vehicles to better protect the “Warfighter”. One of the highlights of the non-technical sessions is the panel of warfighters which brings together combat experienced warfighters to discuss the pluses and minus of the current technology and what they need to better carry out their mission.


Ciara Technologies are experts in building overclocked professional workstations. They recently released the KRONOS 840-G4 which includes the latest Intel i9 Processors. The i9 processors provide larger core count, up to 18 cores and the Ciara machines provide machines that run up to 4.6 GHz for all processors all the time, where the base clock speed is 3.3 GHz. The Intel Turbo boost only operates for short durations to maximize performance and it only applies to a limited amount of the cores which means if your application uses too many cores the system defaults back to the base clock speed. Overclocking is quite different, all cores run at the higher frequency all the time which also includes overclocking the memory as well. The KRONOS workstations also include the latest liquid cooling technology for the CPU that insures a reliable system. The combination of GPU Technology for massively parallel processing and high performance CPU processing results in a workstation that rivals cluster based solutions.


GPU computing on a laptop. The latest laptops are equipped with NVIDIA GTX10xx processes which can also be used for computing. CertaSIM recently acquired a laptop with a GTX 1060 GPU which has 6 GB of memory. We ran some of the models that were presented at the GTC2018 conference and the results were quite impressive. The models were that of a hypervelocity oblique impact which is representative of space debris impacting a satellite. The models were used to show performance and high resolution. The models were run with the IMPETUS Afea γSPH Solver which is a full continuum particle model that takes full advantage of GPU Technology. There were 3 resolution models tested, an 800K particle model, 6.5 million particle model and a 10 million particle model. All ran successfully. The 800K model ran in under 7m, the 6.5 M model ran in 2hr 38m and the 10M model ran in 7hr 4m on the laptop. The chart below shows runtimes for the various NVIDIA GPUS on a workstation, the runtimes are in seconds. Note that the 800K model took only 56 sec using the GP100.

To compare with a cluster based solution, a similar 800K model took a whopping 20min on a 36 core cluster. Certainly no match for GPU massively parallel processing.
