For example, if you have a large building with a ventilation unit on the roof and you have exhaust 30 feet away at a different angle, you need to understand if you will re-ingest some of the exhaust into the ventilation system as well as the wind angle and velocity conditions in which that occurs. With HPC, an engineer is more likely to run a wide range of wind conditions and accurately find the solution space where reingestion occurs. Value of HPC Solutions There are two ways of predicting the ROI of increased simulation output: time savings and fidelity. 1. Time Savings - Without access to HPC, simulation engineers can spend upwards of 40% of their time waiting for results to converge. Assume: a. The engineer is fully focused on simulation work b. An internal billing rate of $150 per hour c. Utilization rate of 75 percent A savings of 40 percent of billable time equals a savings of $100,000 per year per engineer. 2. Fidelity Increase - Time is often set by practical deadlines, and engineers generally concede some fidelity to get the work done on time. So, when speed increases, fidelity generally does as well. That increased fidelity can have significant financial ramifications that can be quantified by a reduction of product failures in prototype testing, recalls, poor reviews, etc., as well as increased innovation, shorter time to market, and the ability to enter new markets. The increase in simulation throughput enabled by HPC results in: • A more empowered design engineering team • More data-driven design decisions • Competitive advantages over rival companies • Reduced prototyping costs Rent vs. Own vs. Both Customers often come to us asking if they should buy or rent HPC hardware and software. Many are surprised to hear that we typically recommend both. An Analogy If you drive to work every day and only occasionally need to transport large items between offices, your best option is to buy a commuter car and rent a larger transport vehicle whenever needed. This same logic applies to HPC solutions. Understanding and Predicting the ROI of High-Performance Computing
