Reserve workstation(s)
Once you have a credit account with compute units available, you can go to the
"Reservations"
page (submenu under the "User:" tab). Your
account will be charged by wall clock hours used (down to
appropriate fraction of an hour). Only actually used hours are
charged, if you cancel your reservation before it starts nothing is
charged, if you cancel before it ends only the actual hours between
start and cancel are charged. You can manage your reservations on the
"My Reservations" page. You can also create and manage
reservations on the command line with /programs/bin/labutils/biohpc_res
. (Try biohpc_res --help
for usage).
NOTE: "time used" is defined as the
wall clock time elapsed when your reservation is active - it has
nothing to do with how much you actually used the CPU/RAM etc during
this time. Amount of hours available on a credit account will depend
on the machine type, conversion rates are listed on
pricing page
and on My Credit Accounts, the latter also shows how many
hours you have available on each server type.
When you are done computing, you can cancel your reservation on the webpage, or with the command
biohpc_res cancel --current
executed on the reserved machine.
Cancelling the reservation ensures you are only charged for the time used.
