MPICH是MPI的重要研究,提供了一系列的接口函数,为并行计算的实现提供了编程环境.

Goal  : ${progname} invokes the appropriate log viewer based on suffix
        of the logfile or as instructed by user through option, -logtype.

Usage : ${progname} [-help] [-logtype=LOGFORMAT] [logfile]
-help               - print this help message
-logtype=LOGFORMAT  - invoke the log viewer to view logfile of type LOGFORMAT. 
                      LOGFORMAT can be one of the following : clog, slog, alog
                      Only one of the above 3 log formats is needed here.
 logfile            - the name of the logfile.  If option, -logtype=, is
                      NOT given, the log format will be determined by the
                      suffix of the logfile name.
