Access
4 minute read
User account requests
- Email user account request to support@hpcc.ucr.edu. Please include full name, NetID and email address of both user and PI. Users need to be members of the PI’s group. Prefrentially, user account requests should come from the correspoding PI directly. If the request comes from a new user then the PI needs to be included in the email exchange (CC’ed).
- An FAU for the annual subscription fee (see below) is required if a PI’s lab is not registered yet.
After the access information for an account has been received via email, new users want to follow the login instructions here.
Recharging rates
HPCC’s recharging rate structure is outlined below. A more formal summary is available here.
Lab-based Registration Fee
An annual registration fee of $1,000 gives all members of a UCR lab access to our high-performance computing infrastructure.
The registration provides access to the following resources:
- Over 6,800 CPU cores (60% Intel and 40% AMD), ~60,000 cuda cores (Nvidia A100, P100 and K80 GPUs), ~2PB parallel GPFS-based disk space, 512GB-1TB of memory/node, etc. More details are available on the hardware page.
- Over 1000 software packages and community databases. Details are available on the software page.
- Free attendance of workshops offered by HPCC staff
- Free consultation services (up to 1 hour per month)
- Note: there is no extra charge for CPU usage but each user and lab have CPU quotas of 256 and 512 CPU cores, respectively. Computing jobs exceeding these quotas can be submitted but will stay in a queued state until resources within the quota limits become available.
Big data storage
Ownership models
Disk storage
- Lab purchases storage hardware (e.g. hard drives) according to the specifications of the facility. Owned hard drives will be added to the facility’s parallel GPFS storage system. The annual support fee for owned disk storage is $250 per 10TB of usable and backed-up storage space. The owned storage space is only available to the users of a PI or those a PI wishes to give access to.
- Owned storage can be attractive for labs with storage needs above 40 TBs.
Compute nodes
- Lab purchases compatible computer nodes (e.g. with supported network cards). Examples of popular high-density architecture are quad node systems shown here: HDX XT24-5260V4 and HDX XN24-52S1. A quad node system includes 4 nodes each configured with two 16 core Intel chips (total physical core count 128), 512GB of RAM, 1.2TB SSD and FDR-IB interconnect. Similar options exist for AMD EPYC and GPU nodes.
- Nodes are administered under a priority queueing system that gives users from an owner lab priority and also increases that lab’s overall CPU quota (see above) by the number of owned CPU cores.
- Owned computer nodes are an attractive solution for labs requiring 24/7 access to hundreds of CPU cores with no or only minor waiting times in queue.
Software install
- Registered users can email software install requests to HPCC’s issue tracking system @ support@hpcc.ucr.edu. Install requests are addressed in the order received. Simple installs are addressed within 1 to a few days. Complex installs may take longer.
Department cluster membership with owned computing nodes
This option addresses the need of department-level HPC access where the standard
PI-based membership is not practical, e.g. provide cluster access to large number of undergraduate
students in classes. Under this model a department purchases computer nodes
that will be administered similarly as described above under the Ownership
model. Due to the large number of expected users from departments, the
CPU quota per user is usually lower compared to the PI-based model.
Using HPCC cluster for classes
To use the HPCC cluster for teaching, please coordinate with the systems
administrators (support@hpcc.ucr.edu) at least 4 weeks prior to the start of a
class so that there is enough time for planning. Details that need be discussed
includes the number of user accounts required, special software requirements,
creation of a class-specific Slurm partition, data storage reservations, as well
as other needs that may vary for different classes.
External user accounts
Accounts for external customers can only be granted if a lab has a strong
affiliation with UC Riverside, such as a research collaboration with UCR
researchers. Both the corresponding UCR PI and external collaborator need to
maintain an HPCC subscription. External accounts are subject to an annual
review and approval process. To be approved, the external and internal PIs have
to complete this External Usage Justification.
