When calculating an RFEM file, Task Manager shows a usage of about 50% only. Why does the calculation not use all kernels?


The calculation does use all kernels. Some processors (Intel Core i7, i9, XEON...), however, support Hyper-Threading Technology. This means that each physically available procesor core is split up into two virtual cores for applications. This aims at a better usage of the single units of the core. There are some applications which benefit from this and run faster. However, this is not the case for the computation kernel of RFEM. Therefore, the computation kernel of RFEM often only uses the physically available cores, and Task Manager displays that the processor seems to only have a usage of 50%.
