This presentation gives the perspective of an ISV (independent software vendor) on the usage of the latest Intel technologies for engineering simulation. It starts off with introducing ANSYS and why our customers have a continually increasing need for higher computing performance so that they can run faster, bigger, and more simulations. In order to meet this continually growing compute demand, it demonstrates how we have worked closely with Intel to optimize our software at different scales of parallelism (from workstation, server-based clusters to supercomputers). Key strategies to enable efficient parallel execution are discussed, and recent examples of the value of software optimization are shown.
