Service Details
The Pay-Per-Use service is based on the private cloud model where HPC cluster resources can be subscribed and provisioned on-demand through a service portal. The Pay-Per-Use facility is designed to provision up to 16 cluster nodes (with 192 processor cores) within a day. Larger cluster can be provisioned within a longer time, where the turnaround time will depend on the size of the request. The basic cluster configuration available for subscription comes with Linux OS, 12-core node with 48GB memory, Infiniband interconnection, 500GB scratch storage space per user, compilers, math libraries and job scheduler.
Who can subscribe
The Pay-Per-Use service is open to researchers at NUS Schools/Faculties, RIs/RCs/RCEs, National RIs/RCs and CREATE.
Charging rate
The full charging rate is $0.045/core/hour; the subsidized rate is $0.015/core/hour.
The current subsidized charging rate does not include the utility (electrical) cost of the resources provided. Such cost may be added in the future due to change in utility charging arrangement.
Please contact the HPC team at to find out which rate is applicable to you.
How to subscribe
To subscribe, researchers will have to first register a charging account with the HPC staff. Billing information such as the billing contact (name, email, telephone and mailing address), WBS number and credit limit (the maximum amount researcher has budgeted for the subscription) will be needed to initiate the subscription. Researchers (through their department's billing contacts) will be billed monthly based on the amount of resources subscribed and the length of subscription. Please communicate with the HPC team at for this service and find out the charge rate that is applicable to you.
Minimum subscription
The minimum subscription for the Pay-Per-Use service is one compute node (12 CPU cores) for seven days.
Billing cycle and contact
The subscriber will be billed monthly. The invoice will be sent to the department's billing contact.
Subscription and administration guide
A service portal user guide is provided for the subscriber to perform the subscription and administration for the Pay-Per-Use service at HPC Cloud service portal.
A user guide is also provided for the users to understand on how to login and use the Pay-Per-Use service.
