We will be using a large cluster of computers at Indiana University you can access with ssh as follows:

ssh quarry.uits.indiana.edu

You will be assigned one of 30 training accounts.  The account names all have the base name "hpstrn" with a number. 
i.e. account names are:  hpstrn01, hpstrn02, ..., hpstrn30

All accounts have the same password:  "hpc at it rocks", where the quotes, of course, are not actually typed.

Once you have an account you can use a simplified form of ssh like this (for hpstrn10):
ssh hpstrn10@quarry.uits.indiana.edu
