Supercomputers “Debugging is all relative”

Supercomputers need super, or at least novel, debugging.

Relative debugging allows programmers to track bugs that creep into software as it is modified, or ported from one system to another, according to Guardsoft. It does this by comparing the execution of a suspect program with a clean version. This differs from traditional debugging in two ways: First, it compares program variables not with the user’s expectations but with another program known to be correct; second, the process can be automated.
