Supercomputing Terms

(alphabetical listing)

account application

The account application comprises the application form, the proposal text, the resume, the performance report, the publications list, and other materials that support a request for use of OSC resources.

Allocations Committee

A committee, comprising volunteers from the Statewide Users Group, that meets bimonthly to make decisions regarding allocations in general and account applications in particular.

authorized institutional official

The only hard copy item required for account applications is the signature page. The authorized institutional official can be an OSC site consultant, the chair of your department, the dean of your college, or a person who oversees accounts in your department or college.

authorized users

Authorized users include the principal investigator and secondary investigators who are part of the research team on a project. For classroom accounts, authorized users are the registered students and teaching assistants.

authorized users, adding new ones to existing project

To add a new authorized user to a project, the principal investigator should send the following information about the new user to account@osc.edu:

      Dr., Mr., Ms, Mrs., etc.
      first name
      middle name/initial
      last name
      position title
      institution
      mailing address
      work telephone number
      fax number
      home telephone number
      e-mail address
      project number
      machines on which user should have accounts
      your fax number, so we can fax you the login account letters

balance

To determine your project balance, please log on to any machine and use the following command: OSCusage To maintain a positive balance, please submit follow-up proposals (either standard or major) before your balance reaches a negative level.

classroom account

A project that allows students to learn high performance computing or to apply high performance computing to a particular subject. Each student receives a userid. The project is good for one school term. The instructor should submit by e-mail a brief final report about the class. The award is 5000 RUs. Classroom accounts need only administrative review.

major account

A account application for 30,000 resource units. Users request this level when their work is rather constant with a significant use of resources.

NSF Field of Science number

Refer to the list of National Science Foundation's Field of Science numbers. You may find that more than one applies to your work; put up to three numbers in the blanks.

performance report

A report generated by performance tools. Required for major account applications. Please see http://www.osc.edu/supercomputing/computing for machine-specific information.

principal investigator

  • A full-time, permanent researcher or faculty member of an Ohio college or university.
    • Responsibilities of a principal investigator
      • Central contact and administrator of the project
      • Responsible for keeping records of the resources consumed by authorized users and monitoring account balance
      • Notify account@osc.edu of changes/additions in authorized users
      • Forward to OSC, Allocations Committee, copies of papers, preprints, and technical reports written from results computed on OSC's resources
      • Ensure ethical use of OSC's resources by research team
      • Submitting new account applications in a timely manner

project

A project contains one or more proposals, which may or may not be related. Each project has a number consisting of a three- or four-letter prefix and four numbers. Principal investigators may have more than one project, but they should be aware that userids are not transferable from one project to another. Each project contains unique userids. All of the proposals under one project share a common pool of resource units.

proposal

The text of a account application that provides the information noted in the Account Application Process Overview.

publications

The publications section of the account application form should list publications and presentations that acknowledge OSC. New users will not have entries for this section.

resource unit

An RU is a resource unit and an mRU is a milli resource unit (i.e., 1 RU = 1000 mRUs). A resource unit is an aggregate measure of the use of CPU, memory, and file storage. For details on charging algorithms, see Charges for Academic Use. Maintaining a positive balance is the PI's responsibility. Use the OSCusage command to monitor your account balance on a daily basis. Principal investigators should submit follow-up account applications before their projects reach a negative balance.

review process

Standard and major accounts must undergo a review process. Principal investigators provide the names of recommended reviewers, and OSC administrators identify other potential reviewers. These reviewers review the account application and submit their recommendations to the Allocations Committee.

reviewers, recommended

Principal investigators who request standard or major allocations must supply the names of recommended reviewers.

secondary investigators

These are authorized users other than the principal investigator. The PI is responsible for keeping OSC updated on changes in authorized users.

sequence number

Each proposal under a project has a sequence number for use by OSC's database.

signature page

The signature page for first-time principal investigators should be printed, signed by the PI, signed by the authorized institutional official, and faxed to OSC at 614/292-7168..

special account

A special account is one that requires more than 30,000 resource units. Large computing runs and high-consumption software packages sometimes necessitate larger requests. For such a request, please send e-mail to account@osc.edu. Principal investigators who want to request more than 30,000 RUs may be asked to prepare a special petition to the Allocations Committee.

standard account

A standard account is a request for 10,000 resource units. It is a peer-reviewed proposal.

start-up account

New principal investigators who have never had accounts on OSC's high-performance computers may complete a brief on-line request form for a start-up account. This account receives a one-time 5000 allocation, installed automatically without review. PIs are to monitor their project balances and submit follow-up account applications before their account reaches a negative balance.

Statewide Users Group

The Statewide Users Group comprises representatives from Ohio's colleges and universities. The members meet every other month and serve as an advisory body to OSC.

support from other sources

If your research is supported by monetary accounts from funding agencies, the Center appreciates learning of this. Such data helps the Center determine its role in Ohio's research activities.

type of account

The Center categorizes accounts as classroom (5000 RUs), standard (10,000 RUs), major (30,000 RUs), and special (more than 30,000 RUs). Start-up accounts for first-time users of OSC receive an automatic, one-time 5000 RU allocation.

userid

Unique login name of a user on a particular project. If a user is on more than one project, that user will have more than one userid.

userid, changing owner

It is possible to change the owner of a userid. The request must come from the principal investigator. Send e-mail to account@osc.edu, giving the userid, the current owner, and the following information about the new owner:

Dr., Mr., Ms, Mrs., etc.
first name
middle name/initial
last name
position title
institution
mailing address
work telephone number
fax number
home telephone number
e-mail address
project number
machines on which user should have accounts
your fax number, so we can fax you the login account letters
