## PSI HPC@CSCS
|
|
|
|
For offering high-end HPC sources to PSI users, PSI has a long standing collaboration with
|
|
the national supercomputing centre CSCS (since 2005). Some of the resources are procured by
|
|
central PSI funds while users have the optionsof an additional buy-in at the same rates.
|
|
|
|
### PSI resources at Piz Daint
|
|
|
|
The yearly computing resources at CSCS for the PSI projects are 627,000 NH (Node Hours).
|
|
The yearly storage resources for the PSI projects is a total of 80TB. These resources are
|
|
centrally financed, but in addition experiments can individually purchase more resources.
|
|
|
|
### How to request a PSI project
|
|
|
|
A survey is sent out in the third quarter of each year. This survey is used to request
|
|
CSCS resources for the upcoming year.
|
|
|
|
Users registered in the **PSI HPC@CSCS mailing list** <psi-hpc-at-cscs@lists.psi.ch> will
|
|
receive notification and details about the survey, in example:
|
|
* Link to the survey
|
|
* Update of resource changes
|
|
* Other details of the process
|
|
|
|
Generally users need to specify in the survey the total resources they intend to use
|
|
next year and also how they would like to split it over the 4 quarters (e.g. 25%, 25%,
|
|
25%, 25%). In general, we provide the possibility to adapt the distribution over the
|
|
course of next year if required. The minimum allocation over a year is 10,000 node hours.
|
|
|
|
By default allocated nodes are on the CPU partition of PizDaint (36 cores per node).
|
|
However, allocations to the GPU partition are also possible (1 x NVIDIA P100 and 12cores per
|
|
node), but needs to be splicitly stated in the survey.
|
|
|

|
#### 2023
|
|
|
|
The yearly computing resources at CSCS for the PSI projects in 2023 are 522,500 NH (Node Hours). The yearly storage resources for the PSI projects is a total of 80TB.
|
|
These resources are centrally financed, but in addition experiments can individually purchase more resources.
|
|
|
|
PizDaint resource distribution for the different PSI projects in 2023 is detailed in the following Excel file: [PSI_CSCSAllocations2023.xltx]({{ site.url }}/admindoc/downloads/CSCS/PSI_CSCSAllocations2023.xltx) directly.
