# Usage:
# process_plot_tasks_MPI nprocess time-range-ms
#
# Description:
# Process all the thread info files in the current directory
# creating task graphs for all MPI ranks and all rank threads.
#
# The input files are created by a run using the "-y interval" flag and
# should be named "thread_info_MPI-step<n>.dat" in the current directory.
# All located files will be processed using "nprocess" concurrent
# processes and all plots will have the given time range. An output
# HTML file "index.html" will be created to view all the plots.
