MICRO Benchmark: double-subtract

Benchmark from Tsoutsouras et al. MICRO paper.¹

Performs floating-point subtraction of two variables A and B with associated distributions and places the result in C.

Arguments

double-subtract -a <samples file for A> -b <samples file for B> -m <mode>
	-a <samples file for A>: set to `input-A.txt` by default
	-b <samples file for B>: set to `input-B.txt` by default
	-m <mode>: 1 for explicit computation, 0 for implicit uncertainty tracking (0 is the default)

Inputs

The samples are stored in a text file. The first line of the file is the number of samples that follow.
