This is a simple test for m-electron Pfaffian update performance. At the moment, PfUpdate_Tests.cc is the only entry. Just compile PfUpdate_Tests.cc with appropriate compilers should do the job.

• This test is single-threaded.
• Constant n_test and n_update controls number of tests and update interval (i.e. "m" in the "m-electron" update).
• Sorry but inside the program variable k is used instead of m to denote this size of update.

Roadmaps:

• Test hopping-without-updating performance.
• Avoid in-routine allocation.
• Instead of GETRI/GETRF & SKPFA, use tridiagonal factorization.
• Use SKR2K assembly.
