Marmoset buildserver resource limits

Marmoset buildservers are each limited to a maximum of 16GB of available RAM. Test-writers are responsible for not trying to allocate more than this amount explicitly or their tests will fail.

Marmoset Instance Installation done every Term

NEW Setup jobs on cron.student.cs rather than individual hosts and use "~cs_build/bin/buildserver_hosts_command".

Follow the instructions on how to setup a course.

Current Buildservers can then be checked via https://marmoset.student.cs.uwaterloo.ca/status/QueryBuildServerStatus

Neat tool: marmoset_submit

This handy command line tool allows for submission using the command line. For more info execute ~cs_build/bin/marmoset_submit as your student.cs account.

Useful SQL queries for backend MySQL database

This query gives me the total_size of the relevant column in MB storing submissions for this particular course (for marmoset db on database.cs):

select sum(octet_length(archive))/(1024*1024) as total_size from projects AS A, submissions AS B, submission_archives AS C where A.course_pk=92 AND A.project_pk = B.project_pk AND B.archive_pk=C.archive_pk;
