PLGrid infrastructure offers Users the possibility of scientific computing based on the resources such as::

• Computing (CPU, GPU – computing resources, processor time in hours),
• Storage (data repository),
• Cloud (running virtual machines).

Basic information

...

• PLGrid grant allows access to PLGrid resources. 
• Grant is a contractual agreement between the User and PLGrid Infrastructure. This agreement determines amount and parameters of resources available to

• User/

...

• workgroup and time when the resources can be used to achieve scientific goals
• Grants are always associated with a workgroup. Workgroup consists of one or more users and is an entity which negotiates, agrees to, uses and later reports the usage of a grant.

There are two types of resource grant:

• trial grant - for testing purposes in situations when user wants to test what amount of resources or what services they need in order to conduct actual research. Such grant allows for use of 1000 CPU hours and 10 GB of storage in every supercomputer center.
• proper grant - allows for larger allocation than trial grants. It has to be applied for and accepted by a resource administrator. It is strongly advised that actual scientific work is conducted within proper grants.
  

• Pilot grant – a small grant that the User obtains on request. It does not require negotiation of resources with the Centers and includes 1,000 computing hours and 10 GB of disk space at each PLGrid Center except the Athena cluster, to be used during a year. Resources under the Pilot Grant are available up to one hour after requesting them.
• Proper grant – provides opportunity to obtain a larger amount of computing resources and requires the settlement - reporting the results of research being conducted using PLGrid Infrastruture resources. Resources negotiated under this type of grant can be shared by a larger number of Users (members of a given workgroup).
  

Using PLGrid resources

Check if the software You want to use is available on the clusters. 

Search for the software You need:

1. 1. in the Catalog: https://aplikacje.plgrid.pl/, lub:
   2. on the clusters UI - using the command: module avail |& grep -i software_name

Find out what resources the cluster has.
