Disk quotas are enabled on project directories. ALCF's HPC systems use the swift-home file system located at /lus/swift/home where quotas are also enforced. Theta has three project file systems available to user. Details on the home file system are listed in file systems. Following are descriptions and examples for the home file system, as well as the theta-fs0, grand and eagle project filesystems.
Home Directory Quotas
By default, each home directory is assigned a default of 50GB. File ownership determines disk space usage.
To check the home directory usage, enter this command:
> myquota Name Type Filesystem Used Quota Grace ========================================================================================================= userX User /lus/swift 44.13G 50.00G none
Project Directory Quotas
The Grand, Eagle, and Lustre project file system (/lus/theta-fs0) support project quotas. The amount of data stored under /lus/
To check project quota usage on the file systems, enter this command:
> myprojectquotas Lustre : Current Project Quota information for projects you're a member of: Name Type Filesystem Used Quota Grace ============================================================================================================== projectX Project theta-fs0 354.4T 700T - projectY Project theta-fs0 916k 1T - projectZ Project grand 8k 1000T - projectX Project eagle 1.87T 1000T -
Requesting a New Eagle Allocation
For requesting a new project having an allocation on Eagle (with or without a compute allocation), please make a request by filling out the Director's Discretionary allocation form. Note that all new compute projects will have Grand as the default file system.
If you need a quota increase for Director's Discretionary allocations, please make a request by filling out the Director's Discretionary allocation form.
If you need a quota increase for your INCITE/ALCC/ALCC/ESP project directory, please send an email to email@example.com with the machine, project name, new quota amount and reason for the increase.
