ATCA

ATCA electronics for HPS run designed in SLAC.

• SLAC confluence instructions: [[1]]

• serial connection to atca1 crate:

root/HpsRoot
115200
Ifconfig eth0 down
Ifconfig eth0 up 129.57.86.147

• DTMs/DPMs nfs mount

Clonfarm1 machine is used as file server for DTMs/DPMs, because they are not supporting newer nfs versions required by modern file servers like clonfs1. Make sure nfs server is set and running on clonfarm1. File /etc/exports suppose to contain following lines:

/data/hps/slac_svt/daq 129.57.0.0/16(rw,sync,no_subtree_check,no_root_squash)
#/data/hps/slac_svt/cache 129.57.0.0/16(rw,sync,no_subtree_check,no_root_squash)
/data/hps/slac_svt/server 129.57.0.0/16(rw,sync,no_subtree_check,no_root_squash)
/data/hps/slac_svt/diskless 129.57.0.0/16(rw,insecure,async,no_subtree_check,no_root_squash)

Run following to make sure, restart if needed:

systemctl status rpcbind
systemctl status nfs-server

• DTMs/DPMs boot

They are dhcp-boot devices, all settings are done by jlab computer center (Carl Bolitho). After boot, check it by logging in, for example ssh root@dtm1 with pass root (be patient, may take some seconds to login).

• some useful scripts in $CLAS/slac_svt/svtdaq/daqV2/rceScripts/:

reboot_cobs.sh - crate power recycle
shutdown_cobs.sh - turn power off (can be turned back on by reboot_cobs.sh)
rem_udp_server.sh - ... (have to run it)
rem_control_server.sh - start GUI server
start_gui.sh - start gui

LOGIN and use of the test setup at SLAC

Tunneling to and starting VNC server at SLAC:

ssh -L 5905:localhost:1234 jlabl1
ssh -L 1234:localhost:5905 rdsrv117.slac.stanford.edu
vncserver :5 -geometry 1800x1000 -localhost -nolisten tcp
top

vncserver -kill :5

To have write access on develpc:

ssh clasrun@develpc
sudo tcsh

Running DAQ:

clasrun account can get root access with:
sudo bash

ssh clasrun@slac1
killall runcontrol rcServer rocs (cleanup just in case)
runcontrol -rocs -log
click on "rocs" tab on the right-top of the screen to observe built-in xterms
click "Configure", pick configuration "slac", processes have to be started in xterms
click "Download" and pick trigger file "slac1.trg"
click "Prestart"
click "Go"

• trigger file "slac1.trg" is located in default directory

$CLON_PARMS/trigger/. It contains electronics settings overloading defaults from $CLON_PARMS/ti, $CLON_PARMS/fadc250/ etc. In particular

  TI_RANDOM_TRIGGER 1 3

enables TI internal random pulser with prescale 2**3, with prescale 3 event rate will be about 50kHz.

Rogue GUI:

ssh clasrun@develpc
bash
cd /u1/hps/server/heavy-photon-daq/software
conda activate rogue-hps-dev-rth
python scripts/SvtCodaRun.py

Reboot RCE:

source /u1/hps/setup_env.sh
cob_rce_reset dev-crate1-sm/2

RCE boot status:

cob_dump -rce dev-crate1-sm
