We use CST microwave studio (<a href="https:&#x2F;&#x2F;www.cst.com&#x2F;Products&#x2F;CSTMWS" rel="nofollow">https:&#x2F;&#x2F;www.cst.com&#x2F;Products&#x2F;CSTMWS</a>) for a project. Calculation time on a Xeon E5-2680 was about 50-60 hours per simulation, together with a Tesla K80 it was reduced to about 4-5 hours. Pretty impressive.<p>Adoption rate isn&#x27;t very high, since most applications still don&#x27;t use that power.
