The article references Dixit et al. for an example of a root cause investigation of a CEE which is an interesting read: https://arxiv.org/pdf/2102.11245.pdf
> After a few iterations, it became obvious that the computation of πΌππ‘(1.153)=0 as an input to the math.pow function in Scala would always produce a result of 0 on Core 59 of the CPU. However, if the computation was attempted with a different input value set πΌππ‘(1.152)=142 the result was accurate.
