IRIS Linux DAQ cluster

IRIS is composed of 5 machines

• IRIS00 - Main NFS server and DAQ (experimental floor)
• IRIS01 - Auxiliary analysis computers (ISAC-II north counting room)
• IRIS02 - Auxiliary analysis computers (ISAC-II north counting room)
• lxiris01 - VME processor for ADCs Mesytec MADC32s (experimental floor)
• lxiris02 - VME processor for TDCs CAEN V1190s (experimental floor)

and 2 VME crates:

• irisvme1
• irisvme2

Home directories: on iris00 2x240GB SSD (ZFS mirror) /home1

Data storage: on iris00 2x20TB HDD (ZFS mirror) /zdata/iris, NFS mounted as /iris/data0/iris

Dcache

• apt install dcap dcap-dev
• add to rc.local

mkdir -p /daq/pnfs
mount trdata00:/pnfs /daq/pnfs -w -o noac,vers=3 &

How to rebuild IRIS DAQ

• build EPICS see https://epics.anl.gov/

cd $HOME/packages
git clone https://github.com/epics-base/epics-base
cd epics-base
git checkout R7.0.8
make -j
ls -l bin/linux-x86_64/

• build MIDAS with EPICS:
  • set MIDASSYS to $HOME/packages/midas
  • set EPICSSYS to $HOME/packages/epics-base
  • cd $MIDASSYS
  • make cmake
  • check that build/examples/eventbuilder/mevb and build/examples/epics/fe_epics were built

• build ROOTANA
  • make sure ROOTSYS is set and points to a working version of ROOT
  • cd $HOME/packages/rootana
  • make clean; make
  • there should be no errors

• build iris-daqtools
  • cd $HOME/packages/iris-daqtools
  • rm -rf build; mkdir build; cd build; cmake ..; make
  • there should be no errors

• build VME frontends and event builder
  • cd online/src
  • make
  • feairis.exe, fetiris.exe and eb_iris.exe should be built
  • event builder should be run: eb_iris.exe -b BUF

• build DT5740 frontend
  • install CAEN drivers and libraries
  • cd online/dt5740
  • make
  • fedt5740.exe should be built

• build analyzer
  • cd $HOME/current/anaIris
  • make
  • there should be no errors, bin/anaIris should be built.

Install CAEN DT5740 driver

• ssh root@iris00
• download and untar CAENUSBdrvB-1.5.5
• apt install linux-headers-generic
• apt install gcc-12 ### only if "make" complains about it!
• cd CAENUSBdrvB-1.5.5
• make
• make install
• modprobe CAENUSBdrvB
• in dmesg and in /var/log/syslog

now go back to iris@iris00, cd online/dt5740, ./fedt5740.exe should print this:
