Older CPUs and the instruction set dilema


The speed up of numerical code by advanced instructions sets provided by a CPU can be essential. However, not every customer might have the latest CPU, so the software either needs different branches and provide multiple options for download, or one neglegts the speed-up.

Recently I compiled with AVX2 instruction set and realized that fiberdesk is crashing on older systems. Originally, I thought it is a Windows 7 bug, however, it just only correlated with Win7 as all these PCs also had an older CPU.

I just uploaded a new version of fiberdesk, which should now work with every CPU again.
