资源说明：Parallelize dnadist using MPI
Shankar Lakshmanan, Cody Leach, Keith Luchtel CSCE 456 DNADIST Project FILES dnadist.c - The source code for the main program, DNADIST. seq.c, seq.h - The source code and header file for the sequence library (part of the Phylip library). phylip.c, phylip.h - The source code and header file for general Phylip functionalities. Makefile - The makefile to compile the program. group7_report.pdf - The written report to accompany the program. maui.job - The maui submission script to run the program. README - The file you are currently viewing. :) HOW TO COMPILE On PrairieFire, type the following command: make dnadist HOW TO RUN Before the program can be ran, the input file needs to be in the same directory as the program. The name of the input file needs to be 'infile'. On PrairieFire, the program needs to be submitted to the Maui scheduler. This can be accomplished by typing the following command: qsub maui.job CHECKING THE STATUS OF RUNNING JOB Jobs being ran can be checked using the qstat -u [username]. This will show all running jobs for the username given. (exclude the brackets). OUTPUT The output will be put into a file called 'outfile' in the same directory as the program. HOW TO CHANGE THE NUMBER OF PROCESSES: The number of processes that run the program is specified in the maui.job file. In the maui.job file, there is a line that is similar to the one below: #PBS -l select=X:IB 'X' is the number of processes that will be running the program. For example, if the program is run on 8 processors, then the line in the maui.job file should look like the following: #PBS -l select=8:IB ERRORS Any errors that may potentially occur will be put within the mpi.stderr file. If something does not run as expected, look within this file to find the cause.
