Usage Charges


Charges for usage will be based on:

High Priority Queues:

These queues have higher priority than the regular queues. The details of the queues are given in the High Priority Queues page.

The charges for using these high-priority queues are as follows:
  • Charges for CPU usage: Rs. 1.50 per CPU core hour.
  • Charges for GPU usage: Rs. 100 per GPU hour.

Note: These queues will be allowed access to the users only on advance payment.

To obtain access to these high-priority queues, users should submit a request on the NIS Portal -> Resorces
Regular Queues :

Regular queues are provided by default to users who have access to the Cray system.

Charges for usage will be based on annual usage according to various slabs as follows.The slabs correspond to usage by a faculty’s group / lab in a year:

CPU-based Supercomputer Systems including the current (SahasraT Cray XC40 CPU, Roddam Narasimha CPU) systems and future systems

Free usage:

  • Usage of up to 2000 core hours in a year will be provided for free.
  •  In addition, new users will be provided 1000 core hours free to get acclimatized with the system and for debugging purposes. These free hours will have to be used within the first month of usage.
  • The above slabs are applicable for the CPU usage in the current SahasraT Cray XC40 system as well as the future systems, e.g., NSM system. 

 

Modes of payment

Faculty can either make payments against usage or can make advance payments for future usage. For both kinds of payments, the payment form given in the link at the top of this page can be used.
