Feature: Predict throughput for all possible alignment offsets with error bars #5

Open pervognsen opened 3 years ago

pervognsen commented 3 years ago

Right now you can only specify a single alignment offset manually. It would be useful to offer an option where uiCA performs its simulation for all possible alignment offsets and gives you error bars for its output values based on that. This would give you an idea of how sensitive/robust a block is with respect to alignment. (Perhaps this could be part of a more general feature to let you simulate across a range of different parameters, e.g. different microarchitectures, with a statistical summary of the variation?)

The -arch and -alignmentOffset parameters now support the option all.
