Over at the Ansys Blog, Wim Slagter writes that there are six common myths about HPC for engineering simulation.
Myth Number 1. High-Performance Computing is available on supercomputers only. Although engineers usually know that HPC stands for high performance computing, I’ve met quite some engineers who do not realize that HPC is already available on their desktop. A decade ago, HPC may have indeed been primarily associated with big supercomputers. However, the computer industry has delivered enormous increases in computing speed and power at consistently lower costs. Think about more compute cores per CPU, integrated I/O on processor die (yielding higher memory bandwidth), more and faster memory (channels), larger L3 cache size, faster disk storage (like solid-state drives for ANSYS Mechanical), faster interconnects, AVX support, etc. Through these advances made I can counter this myth #1 by stating that HPC is today available throughout the entire computer spectrum, at the entry level from tablets running ANSYS Mechanical to multi-core laptop and desktop computers, as well as the bigger workstations but of course also computer clusters at the other end of the computer spectrum.
Slagter lists the other HPC Myths as follows:
- HPC is only useful for CFD simulations.
- I don’t need HPC – my job is running fast enough.
- Without internal IT support, HPC cluster adoption is undoable.
- Parallel scalability is all about the same, right?
- HPC software and hardware are relative expensive.
