Accounts should have been created for everyone in the class at the beginning of the semester. If you do not have an account (perhaps you registered late) email the instructor. (Don't wait until the last minute.) If you find one of these machines to be overloaded or unresponsive, you can always log into another one.
For a warm up assignment, you will make some observations about the ND Condor pool, and then learn how to submit simple jobs. To begin, read these two pages:
condor_statusThere is much more information available than is shown in the basic display. To show all information available about every machine:
condor_status -longTo customize the basic view, try a command like this. Note the similarity to printf format strings.
condor_status -format "%s\t" Name -format "%d\n" TotalMemoryNow answer the following questions about each of the Notre Dame Condor pool:
#!/bin/sh uname -a date sleep 1
Once you are 100 percent sure that one job works correctly, then write a single condor_submit script that submits one thousand jobs like the one above, each writing output to a separate file. Make sure that your submit script generates a user log file as follows:
log = userlog.logOnce the batch is complete, the file userlog.log will tell you everything that Condor did on your behalf to execute the jobs.
