Please let me know immediately if you have any problems logging in (using ssh, as usual) to any of these systems. See HERE for some additional information concerning these new machines.
IMPORTANT NOTE: At the current time, it seems that the "outside world" may not be properly aware of the symbolic names lnx1.physics.ubc.ca etc. If you have problems connecting to one of the lnx machines from outside the physics.ubc.ca domain, try connecting using the actual IP numbers of the machines:
Machine IP number
lnx1.physics.ubc.ca 142.103.235.134
lnx2.physics.ubc.ca 142.103.235.135
lnx3.physics.ubc.ca 142.103.235.136
Note that, within a shell, you can generally use an IP number anywhere
that you would use a hostname, e.g.
% ssh matt@142.103.235.134

Note that your home directories for the cluster are on the specific (front-end) machine

set path=($HOME/bin $HOMEMWC/scripts /usr/local/bin /usr/java/bin $path)Although the latter (and original default) setting still ensures that '.' (the current directory) is in your path, since the system start-up script includes '.' in the path, the former, "corrected" setting will ensure that the current directory is always searched first when a command is issued.

Tuesday 10:30-11:30 AM -- Hebb 13If at all possible, please attend at least one of these classes (and, if feasible, at least part of both), since the most important order of business will be to reschedule the meeting times, so that if possible, all who wish to take the course may do so without conflict. The instructor is aware that some students currently have conflicts and will do everything possible to resolve this matter.
Be sure to come to class with your current schedules so that we can do the re-scheduling as efficiently as possible
If you CANNOT attend EITHER of the above classes, please e-mail
your schedule to the instructor, Matt
