Lab Credit Accounts, Costs and Charging
Maintaining such a large pool of workstations along with the
software and access infrastructure takes a lot of time and effort.
Machines gradually age and need to be replaced. Therefore CBSU has
to recover its BioHPC Lab investment by charging users for access.
Every BioHPC Lab user must have access to (or be an owner of) an
Lab credit account with hours available to be used. Every user can set up a Lab credit
account (using "My Accounts" page), but
we strongly recommend that all users from the same research
group use one Lab credit account created and maintained by a designated
group member, the Lab credit account owner can add (and remove) other users as
needed. Each Lab credit account must be credited with hours, it can be done by
selecting "Add Hours" link on "My Lab Credit Accounts" page, the hours can be
purchased with a Cornell account or a credit card (processed by
Cornell Store, CBSU does not store nor processes credit card
information). Pricing depends on the workstation type, but since it
only covers our costs it is generally very low, even compared to
purchasing a new machine. Current pricing is listed on
In order to reserve workstation time user needs to have access to a
Lab credit account with sufficient amount of hours. A user may belong to more than
one Lab credit account, which can be selected on reservation page. Only actually used hours are charged, if
a user cancels or
shortens the reservation only the hours that have been used will be
subtracted from the Lab credit account. However, available hours are computed
with all the reserved time included to prevent overbooking. 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. "Time used" reflects
the span for which you had the workstation reserved.
There are different types of Lab machines and you need appropriate
Lab Credit Accounts for them - e.g. general workstations, medium
memory workstations, large
memory workstations. Cost of time for different workstation types is
different, and this is the reason you need different credit accounts.
It is possible to transfer hours from one credit account to another,
provided that you are an owner of the source account and you are allowed
to use the target account. If transfer occurs between different
account types the hours will be converted according to current
pricing. You can access transfer page from the bottom of "My Lab
Credit Accounts" page or directly
Each new research group may request an exploratory Lab credit account with free
100 hours, please contact us by e-mail at
firstname.lastname@example.org for more details.
This is one time credit for a new PI only, not for each new project.
In exceptional circumstances CBSU Advisory Board may grant free Lab
hours, application for free hours must include disclosure of the
group financial standing (including justification why the group
cannot afford Lab fees) as well as the research/educational project
description. The application should be send to
