Here are some basics on Grid things. First, I know that my certificate needs to be
in place. I took the .p12 file that I had created when I got my certificate, and
copied it over to gpn-husker. Then, I followed the instructions at
<http://www.doegrids.org/pages/cert-request.html#Globus>. I did have to create
that .globus directory first. I also had to set the permissions right on the
two files that are created:

chmod go-rw /home/bloom/.globus/userkey.pem
chmod 644 /home/bloom/.globus/usercert.pem

Then I was able to do grid-proxy-init and give my password. And that in turn
allowed me to do all the basics given at <http://t2.unl.edu/grid_user>, such
as globusrun and voms-proxy-init (except I used cms rather than gpn) and
globus-job-run. This will all be helpful, I'm sure.
