Recent development and most usage of mloc has been done under Apple’s Mac OS X and MacOS operating systems, but it has been installed under several Linux distributions successfully, and should be rather easy to port to any Unix-like operating system. MLOC is compiled from Fortran source code, runs in a terminal window and uses only a few basic shell commands.
Disk storage requirements are modest except for some of the digital elevation models (DEMs) that are used to provide topography in some plots. These DEM files are optional, but recommended. An installation with a full set of DEMS will require around 10 GB on disk. The data files for a typical cluster of ~100 events are unlikely to exceed a few MB in size, but each run of mloc produces many output files, some of which are fairly large. If all files from all runs are retained (recommended practice), a cluster directory can easily expand to several hundred MB. On the other hand those files compress well.
Demands on RAM and CPU power go up quickly with the number of events included in a cluster. Current desktop and laptop machines with reasonably high specifications (e.g. a mid-range MacBook Pro) can handle clusters with up to about 200 events before the execution times become unacceptable. The maximum number of events is set at 200 in the code, but it can be easily changed. The code has never been optimized to take advantage of multiple processors or multiple cores.
With careful arrangement of windows mloc can be used effectively on a 15-inch laptop with a good screen, but a large external monitor is very desirable.
