Anyone at Math who is a member of the math.instructors group may send an invite to a NetID to set up a Math account, by going to https://accounts.math.cornell.edu/ and clicking the 'invite user' link.
If you don't have a math account and you would like one, ask a math instructor, or email mathsystems@cornell.edu to request one.
Anyone with a NetID may have a math account, all we ask is that they're respectful of system resources (details below).
==== Resource Usage ====
Commercial software such as Matlab, Mathematica, and Maple have a limited number of licenses. This means there can only be a certain number of these programs running at any given time in the department (including Math machines running in the cloud). Please don't leave these programs running when they're not in use, since you'll be taking up a license. Priority for these programs is for Math faculty, grad students, and researchers. Right now there is no restriction on who can run these programs, but if people have trouble getting an available license, access may be restricted to certain groups.
Files in your home account, under /homes/{username} are backed up every 24 hours. Please be aware of how much space you are using. A few gigabytes is fine, but large data will fill up our backups. Use the /space volume for that. We don't strictly enforce file quotas, but if there is a problem with accounts filling up, we may have to.
The /space volume is large and fast. You may put large amounts of data into /space, all we ask is that you are a 'good neighbor' and don't abuse the privilege. Files in the /space volume can be read at 10GB/second by the calculation machines. /space is not officially backed up, but we usually make snapshots nightly, just in case. This backup is not guaranteed to happen the way it is for your home account. To use the /space volume, make a directory there whose name is the same as your username. Then you may put whatever you want inside that directory.
Each machine has a /local volume. Some are larger than others. They are all VERY fast because they're on the local machine. Remember, the contents of /local will be different on every machine. Just like on /space, you may create a directory with the same name as your username, then put whatever you want inside there. Please be careful not to fill up the volume, use the 'df' command to check the percentage of space used.
