Servers C&CZ

linux login servers
C&CZ administrates the linux cluster nodes for the departments in the beta faculty

Linux cluster

C&CZ does the maintenance for the cluster.

See the Cluster page for detailed info about the Cluster.

Below we put some extra general notes and notes about policy and access.

The ClusterHelp page contains some practical slurm commands about using the cluster.
See the next section in this page to see which servers each department has.
C&CZ info about linux cluster "cn-cluster and other clusters"
primitive list of nodes within "cn-cluster" with owner specified
when logged into a specific clusternode the command "htop" is convenient to see the load on this specific node
running jobs:
- using Slurm clustersoftware you can run a job on the whole/partition of the cluster
- when logged in to a specific machine you can run jobs directly on that machine. However for nodes supporting Slurm this is disapproved.

Policy

Please create a directory with your username in the scratch directories, so it will not pollute the disk with single files and ownership is clear.
Please be considerate to other users: please keep the local directories cleaned up, and kill your processes you don't need anymore.
If large data storage needed:

 Every compute node/server has a local /scratch partition/volume.
 You can use that for storing big, temporary  data.

Access and Usage permission

For servers which are within the linux cluster managed my C&CZ you must first be granted access to one of the unix groups

clustercsedu (for education)
clusterdis(for DaS),
clusterdas(for DiS), or
mbsd(for SwS),
clustericisonly
csmpi
clustericis, which is a meta group consisting of groups: clusterdas, clusterdis, mbsd, csmpi, clustericisonly

To get access to a unix group contact the Support_Staff which can arrange this via DHZ.

Because access granted to the whole cluster (cn00-cn96.science.ru.nl) you can log in to each machine in the cluster. However, you should only run jobs directly on the machines you are granted usage to. So you should ask for usage from the owner of the machine before using it.

The cluster uses the Slurm software with which you can only run jobs on a partition of cluster machines when you are added to the unix groups which are allowed to use this partition. So with the Slurm software usage is controlled by granting access to these unix groups.

Note: it is possible to run on all cluster machines and run jobs there directly, but you SHOULD NOT DO THIS, you MUST use slurm.

Overview Servers

for education

contact Kasper Brink

For education the following cluster servers are available:

 cn47.science.ru.nl	OII node (Supermicro, 2 x Intel Xeon Silver 4214 2.2 GHz, 128 GB, 8x GPU)
 cn48.science.ru.nl	OII node (Supermicro, 2 x Intel Xeon Silver 4214 2.2 GHz, 128 GB, 8x GPU)

OII has one domain group cluster-csedu. Add students to this domain group for access to the cluster. Usage of the Slurm partition 'csedu' is only allowed by member of the 'csedu' unix group.

for all departments

All departments with iCIS have access to the following cluster machines bought by iCIS via the iCIS partition:

   icis partition on slurm22:
     cn114.science.ru.nl  cpu: 2 x AMD EPYC 7642 48-Core Processor , ram: 500GB
     cn115.science.ru.nl  cpu: 2 x AMD EPYC 7642 48-Core Processor , ram: 500GB

When added to the cluster unix group of your departement then you automatically get access to the iCIS cluster machines.

 Cluster: 
    
  We have limited access to the clusters 
    
    * slurm22 with login node cnlogin22.science.ru.nl
       
    For info about cluster and its slurm software to schedule jobs,
    see  https://cncz.science.ru.nl/en/howto/slurm/ which contains also a slurm starter tutorial.
   
 * nodes for research
    
    The  slurm22   cluster has an ICIS partition that contains machines that belong to ICIS and that we may use. 
    The ICIS partition on slurm22 is cn114.science.ru.nl and cn115.science.ru.nl .
     
      icis partition on slurm22:
        cn114.science.ru.nl  cpu: 2 x AMD EPYC 7642 48-Core Processor , ram: 500GB
        cn115.science.ru.nl  cpu: 2 x AMD EPYC 7642 48-Core Processor , ram: 500GB      
     
    For access you need to be member of the mbsd group then you will also automatically become member of 
    the clustericis group which gives you access to the Slurm Account icis on the slurm22 cluster. 
    Ask Harco Kuppens for access.
     
 * nodes for education: 
   
     These nodes are all in the slurm22 cluster and are bought for education purpose by Sven-Bodo Scholz 
     for use in his course, but maybe sometimes can be used for research.

 Alternate servers: 
    
   Several subgroups bought servers at alternate and are doing system administration themselves.
   The server is meant for that subgroup, but you can always try to ask for access.
