We offer a high performance computing cluster, Sol and a Ceph based storage cluster for the Lehigh Research Community.
The computing and data storage resources are available for use in the classroom for registrar scheduled courses. See Teaching Uses below.
All users of Lehigh's research computing systems must obtain an account for their exclusive use with their standard Lehigh University userid.
An HPC account provides access to Sol, a 85-node condo cluster for research. A faculty member may obtain access to Sol by purchasing a minimum allocation of 50,000 core-hours or service units (SU) for $500. Additional allocations can be purchased in increments of 10,000 SUs for $100 each. An allocation cycle begins on Oct. 1 and ends on Sep. 30 of the next year and will not roll over to the next allocation cycle. At launch, there are 1,400,000 SUs available per allocation cycle. Faculty members who require more computing time or want a gauranteed share of total available computing time annually should consider a Condo Investment.
The faculty member or PI can request additional accounts sharing the same allocation for an annual charge of $50 (each). Each service level 2 user has a home directory quota of 150GB.
Account Request: To obtain a HPC account or allocation or both on Sol, the Faculty sponsoring the user account should contact Manager of Research Computing for more information.
In Fall 2018, Research Computing will deploy a refreshed 600TB Ceph Storage solution. Faculty, Departments, Centers and Colleges can purchase a Ceph project in units of 1TB.
Research groups can opt for backup of data to a secondary Ceph cluster in which case
HPC Research groups and Ceph
Research groups that purchase a minimum of 1TB Ceph project for a 5 year duration have the option of using their Ceph projects space as their home directory on Sol. If PIs opt for Ceph projects as home directory forgoing the 150GB home storage quota provided by the $50/user account fee will have their annual user fees waived for the life of the Ceph project. Such PIs can add users to their Sol allocation at no charge during the 5 year life of the Ceph project.
Account Request: To obtain a Ceph project, please contact Manager of Research Computing for more information.
Faculty, Departments, Centers and Colleges can invest in Sol by purchasing additional compute nodes to support their research thereby increasing the overall capacity of Sol. Such investors, Condo Investors, will be provided with an annual allocation proportional to their investment that can be shared with their collaborators. Condo Investors who need more computing time than their investment can purchase allocation, if available, in blocks of 10,000 SUs for $100. These increments must be expended during the allocation cycle that they were purchased and cannot be rolled over to the next cycle.
A Condo Investor can request additional accounts sharing their allocation for an annual charge of $50 (each).
Prospective Investors should review the Condo Program before contacting HPC for investing in Sol.
Additional Storage: Additional storage (Level 1 & 2) is available by purchasing a Ceph project volume @ $200/TB/year. To request additional home directory storage, please submit request to http://www.lehigh.edu/go/rchelp.
Definition of One Core-hour/Service Unit/SU: 1 hour of computing on 1 core. The base compute node on Sol with 20 cores will consume 20 SUs per hour of computing.
More Information: The Research Computing wiki contains details on using the HPC resources, and can be accessed from on-campus locations or via VPN). Polaris and Service Level 2 resources are accessible via ssh. SSH clients are available on all Linux distributions and on MacOS (via Terminal.app). Windows SSH/SFTP clients are available from software.lehigh.edu.
Faculty members considering use of research computing facilities for teaching purposes should submit a request at http://www.lehigh.edu/go/rchelp at least eight weeks prior to the class start date with an anticipated enrollment count, a proposed syllabus, and details of their proposed use of HPC systems.
These accounts are typically associated with a rostered course, and last for the duration of that course (up to one semester). The course instructor can request these accounts for his/her students, and the department offering the course is responsible for paying the associated fees.
A course allocation provides 1TB Ceph space and an allocation based on number of students in the course. The fee is broken down as follows
1 TB Ceph space.: $200
Charge per student: $15
Provides 500 SU/student.
A course with 10 students will thus have a total allocation of 5000 SU that is shared among all students in the course.
Additional allocations in units of
1000 SUs can be purchased for $10 up to 10K SUs and
10K SU units for $100 for allocation sizes > 10K
Instructors requiring assistance with estimating total or per student SU requirements for the course should contact Research Computing Staff at least 4 weeks prior to beginning of the semester.
Usage Policy: Student accounts cannot be shared and will be active until two weeks past the end of the semester. All compute intensive tasks must be submitted via the batch scheduler. On request, LTS Research Computing staff will guest lecture on how to use the resource, write and submit job scripts and monitor jobs. Compute intensive task is defined as any operation on the HPC resource other than editing, copying, moving or deleting files, submitting and monitoring jobs and issuing simple commands such as ls, cp, mv, mkdir, rm, tail, tar, gzip/gunzip, more, cat and less. All student data not saved in the Ceph project space will be purged when accounts are deactivated.
Faculty can request a Ceph project to provide storage resources for coursework independent of accounts on Research Computing clusters. The cost of a Ceph allocation is $200/TB/year and must be paid by the department offering the course. Any request for a Ceph volume for course work will need to be accompanied by
