Each of the 20 graphs within a panel will contain an x-axis that reports
problem size, with all matrix dimensions equal to the problem size (e.g.
_m_ = _n_ = _k_), resulting in square matrices.
The y-axis will report GFLOPS (in the case of single-threaded performance)
or GFLOPS/core (in the case of single- or dual-socket multithreaded
performance), which is simply the total GFLOPS divided by the number of
threads utilized.
This normalization is done intentionally in order to facilitate visual
comparison of multithreaded graphs and single-threaded graphs.
The y-axis will report in units GFLOPS (billions of floating-point operations
per second) in the case of single-threaded performance, or GFLOPS/core in the
case of single- or dual-socket multithreaded performance, where GFLOPS/core
is simply the total GFLOPS observed divided by the number of threads utilized.
This normalization is done intentionally in order to facilitate a visual
assessment of the drop in efficiency of multithreaded performance relative
to their single-threaded baselines.
It's also worth pointing out that the top of each graph (e.g. the maximum
y-axis value depicted) _always_ corresponds to the theoretical peak performance
