Machines and computing environment for the L0Muon Trigger

The machines and directory available at the pit are the following.

User

The common user to work is piyvduval

Disks

All the L0MUON machines mount the same disk space.
The common home directory /home/piyvduval is shared by all our machines but is private to the L0MUON group.

The directory /group/trg is shared by all our machines and by the L0 trigger groups.
It contains the directories:

• /group/trg/L0TRIGGER_SHARED_DATA/BOARDS_ALL
  used to keep the million events used by the server HIGHSTAT test.

• /group/trg/L0TRIGGER_SHARED_DATA/CCPC_SLOTS_IDENTIFICATION/
  in which all the CCPC register their slots and hardware identifications.

Control room monitoring machines

The control room monitoring machine is a WINDOWS machine named LB015W.

To use X graphical interface from the other machines the X Exceed server should be started.
The remote machine the display has to declared:

export DISPLAY=LB015W:0.0 (the alias disp is available under the piyvduval logging)

Any machine can be used in the Control room.
The redirection command has to be modify accordingly: export DISPLAY=LB001W:0.0 for example.

Main ECS server

The name of the machine is tmudaq01

It is the work place from where all tests, supervision and control activities are done.

It contains the following local directories that can't be accessed from the others machines:

• PVSS projects are in /localdisk/pvss
• CCPC mounted disks is in /diskless/ccpc

CCPC Names and MAC addresses

• The names of the CCPC's for processor/controller boards are tmutbQXX
  where Q=[0 to 3] for Q1 to Q4 and XX=[0 to 11 for PB and 15 for CB]

• The name of the CCPC's for TELL1 boards are tmutellqXX
  where XX=[1, 2, 12, 3, 4, 34]

• The detailed association between CCPC name, MAC addresses and board identifier can be found here

• To obtain processing or controller boards names use remote command Read_BoardIdentification with the toolbox

Tell1

For the TELL1 configuration the following information are necessary:

• FORCE 10 switch target MAC address 00:01:e8:22:4b:bb

• TELL1 emitter IP addresses (for data) can be allocated in the range 192.169.4.0/24 (more details)

• TELL1 MAC addresses (for data) can be allocated in the range 00:CC:BB:04:00/24:00
  The last byte is set by the FPGA according to the sending port [0 to 3].

Dedicated nodes to read back events in the pit

The name of the machine is plus01

Dedicated nodes to run the "presenter" in the pit

The name of the machine is hlt01

Gateway to external word

The name of the machine ares gw01 or gw02 from inside LHCb or lbgw.cern.ch from outside LHCb

It is possible to log in console mode to all machines by:

1. logging in the gateway
2. ssh on any other insider machines.

It is possible to do directly a secure copy scp from CPPM to/from the gateway to import or export file to/from the shared disk space.

Miscellaneous machines

• lbpcxp02 is a PC used to program/debug boards with jtag (Administrator LHCb1234)

• tmujtag00 is the jtag switch server to switch jtag flows to the proper board.
