Computation Time and Peak Memory
Computation time and memory data consist of the computation time for the different stages of the solution such as checking the geometry and matrix calculation time. The peak memory and memory per process is also provided.
The final section in the output file gives an overview of the computation time, in seconds, in a
tabular
format:

This table is followed by an output of the peak memory usage (main memory, excluding
possible out- of-core files) which Feko encountered
during any solution
