Billing

See the Billing unit and price calculator at research.csc.fi.

Puhti

Compute billing

Puhti is a heterogeneous system with CPU, GPU and IO nodes and nodes with varying amounts of memory. Moreover, it is possible to use only a fraction of a node and its various resources. The billing scheme charges billing units (BU) in a fair way based on the reserved amount of node resources.

In the billing scheme, the BU consumption rate of a compute job depends linearly on the number of requested cores, the number of requested GPUs and the amount of requested memory. More precisely:

  • Each reserved core consumes 1 BU per hour.
  • Each GiB of reserved memory consumes 0,1 BU per hour.
  • Each reserved GiB of NVMe disk (if available) consumes 0,006 BU per hour.
  • Each reserved GPU consumes 60 BU per hour.

The total BU consumption per hour is the sum of the above terms:

Total BU = ( NCores * 1 + MemGiBs * 0,1 + NVMeGiBs * 0,006 + NGPUs * 60 ) * Walltime hours

Scratch disk billing

The default 1 TiB scratch disk quota is free. Increased quota is charged:

  • 1 TiB consumes 50 000 BU per year.

ProjAppl disk billing

The default 50 GiB projappl disk quota is free. Increased quota is charged:

  • 1 TiB consumes 50 000 BU per year.

Mahti

Compute billing

In contrast to Puhti, in Mahti resources are used and billed per node in all normal partitions. In the interactive partition, which can be used for interactive work, as well as for small scale pre- and postprocessing, the usage is billed per CPU core. Memory is not billed separately.

  • Each reserved node consumes 100 BU per hour.
  • In interactive partition each core consumes 1 BU per hour.

Scratch disk billing

The default 1 TiB scratch disk quota is free. Increased quota is charged:

  • 1 TiB consumes 50 000 BU per year.

ProjAppl disk billing

The default 50 GiB projappl disk quota is free. Increased quota is charged:

  • 1 TiB consumes 50 000 BU per year.

Allas

The Allas object storage is charged:

  • 1 TiB consumes 1 BU per hour.

Monitoring billing unit consumption

In the My Projects page in MyCSC you can study the billing unit consumption and apply for more billing units. There you can easily check who consumed the billing units, when they were consumed and in which service. Note that storage-related billing unit consumption (in Scratch and Allas) is not linked to a specific user account and is reported as "other".
