SLIDE 4
- Run control, general use
– np04-srv-009 and np04-srv-010
- Board readers (Rce, ssp, timing, trigger, …)
– np04-srv-011 to 018
- Felix - np04-srv-019
- NFS servers (no logins)
– np04-srv-007 (6T/10T) – home (3T) and software (3T) – np04-srv-008 (6T/10T) – scratch (3T) and backups (3T)
- Pddaq-gen01 to gen06 – used for test stand
– Convert to np04 when other computers in operation – For now still login as pduser

SLIDE 5
- Individual accounts are active
– List of accounts from np04-daq-dev egroup
- np04daq group account is active
– Login with your own kerberos principal – Everyone with an online account can login as np04daq
- All accounts are in the np-comp Unix group
– Unix groups are set through cern account management
- To install official software login as the np04daq user
– Eliminate software permission issues – Some discussion previously about a software installation account?
Accounts

SLIDE 6
- np04online git repository to store configurations
– Project in the protoDUNE SP DAQ gitLab workspace
- https://gitlab.cern.ch/protoDUNE-SP-DAQ
- SELinux is turned off
– Cause of delay for getting computers configured
- Installations done with pxe/kickstart
– Can reinstall base Operating System easily
- Configured with Ansible (instead of puppet)
– Credit to Karol for driving Ansible configurations – Simplifies adding the same configuration to all computers
Configurations/Installation
21/08/17 Geoff Savage | NP04 DAQ Computing 6
SLIDE 7
- Use lvm for configurations – size is adjustable
- NFS - Only allocated ~60% of disks so far
– np04-srv-007 – 10 TB total
- home – 3TB
- sw – 3TB
– np04-srv-008 – 10 TB total
- rscratch - 3 TB (remote scratch)
- Back – 3 TB
- Local scratch on each computer (~200 GB)
Disk Space

SLIDE 8
- Everyone should login as themselves and np04daq
– Report any issues to me – Check your group membership for your account
- Installing software (directory structure coming soon)
– I will install art daq in the central software area
- Need to get all the packages for building installed
- Then John Freeman will confirm that I installed things correctly
– Identify WIB, Timing, RCE, SSP, trigger, …, software areas in nfs space – Contact me if your favorite editor or other software is missing
- Develop a pddaq to np04 transition plan
– Searching back through old computing items – Run control – Log stash
Moving Forward
21/08/17 Geoff Savage | NP04 DAQ Computing 8
SLIDE 9
- Transition DAQ to NP04 computers
- Networking
– Add 2nd 10 Gbit network connections to Board Reader computers – Install firewall in network switch – Connect SSP, WIB, and timing to CERN network
- Currently on private network
- Access offsite repositories
– Intermediate repository
- Control room computing
Integration
