Debian 7

libc

The Debian 7 libc is 2.13-38+deb7u11, built from eglibc-2.13. This version has a bug in malloc, corrupting memory in heavyly multi-threaded applications. A recompiled version of libc, modified with selected upstream patches, must be installed so the SlsDetector software can run properly:

cpufrequtils

The previous settings disable the ACPI CPU power management interface, so the loadcpufreq INIT service will not be able to load acpi-cpufreq kernel module. In case this is enabled in BIOS in the future, force the ‘performance’ governor in cpufrequtils INIT service:

# as root
lid10eiger1:~ # cat /etc/default/cpufrequtils
# valid values: userspace conservative powersave ondemand performance
# get them from cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
GOVERNOR="performance"

irqbalance

The irqbalance must be installed in order to distribute hardware IRQs to different CPU cores:

# as root
lid10eiger1:~ # apt-get install irqbalance
...

Disk configuration

Find the 4 TByte RAID-0 array in Debian (/dev/sda):

# as root
lid10eiger1:~ # for d in /sys/block/sd?; do \
    echo "$(basename ${d}): model=$(cat ${d}/device/model)" \
         "size=$(python -c "print \"%.1f MB\" % ($(cat ${d}/size) / (2*1024.0**2))")"; \
done
sda: model=LSI2208          size=3811.0 MB
sdb: model=SATADOM-SL 3ME   size=59.6 MB

Install parted and use it to create a GPT and a RAID partition on the entire disk:

Linux maxcpus option

The Supermicro BIOS does not always acknowledge the Disable Hyper-Threading option, so after some reboot conditions the Hyper-Threading is activated and Linux sees twice the number of CPUs. The only way to control this is to limit the number of CPUs used by Linux in the kernel command line.

Edit the /etc/default/grub file and add maxcpus=12 to the GRUB_CMDLINE_LINUX_DEFAULT variable and force the update GRUB configuration file:

# as root
lid10eiger1:~ # cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 quiet maxcpus=12"
GRUB_CMDLINE_LINUX=""
...

lid10eiger1:~ # update-grub
...

cmake

A recent version of cmake (> 3.0) is needed to compile Lima. Debian 7 package is cmake-2.8.9-1, so it must be compiled from the sources. First un-install the Debian package:

# as root
lid10eiger1:~ # p=$(dpkg --list cmake\* | grep '^ii' | awk '{print $2}'); \
    [ -n "${p}" ] && dpkg --purge ${p}
...

and then copy and compile the sources as opid00 and install as root:

# as opid00
lid10eiger1:~ % mkdir -p ~/Downloads/cmake && cd ~/Downloads/cmake
lid10eiger1:~/Downloads/cmake % scp lisgeiger1:Downloads/cmake/cmake-3.8.0.tar.gz .

Network configuration

Intel 10 Gigabit Converged Adapter

Interface association

Force eth2 and eth3 to be in PCI-Express slot #2 ports and eth4 and eth5 to be in slot #1.

First locate the Intel 10 Gigabit X520 Ethernet adapters (reported as Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection):

lid10eiger1:~ # lspci | grep Ethernet
02:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01)
02:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01)
05:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01)
05:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01)
07:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01)
07:00.1 Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01)

Then check the PCI tree:

lid10eiger1:~ # lspci -t
-+-[0000:ff]-+-08.0
...
 +-[0000:80]-+-01.0-[81]--
...
 +-[0000:7f]-+-08.0
...
 \-[0000:00]-+-00.0
...
             +-02.0-[02-03]--+-00.0
             |               \-00.1
             +-02.2-[04]--
             +-03.0-[05-06]--+-00.0
             |               \-00.1
             +-03.2-[07-08]--+-00.0
             |               \-00.1
...

From the tree we identify the parent root device of each Intel X520 Ethernet adapter:

Node Parent
0000:02:00.x 0000:00:02.0
0000:05:00.x 0000:00:03.0

Find the PCI-e slot from the parent root port in the CPU:

lid10eiger1:~ # lspci -s 0:02.0 -vvv | grep Slot
    Capabilities: [90] Express (v2) Root Port (Slot+), MSI 00
        LnkSta: Speed 5GT/s, Width x8, TrErr- Train- SlotClk+ DLActive+ BWMgmt+ ABWMgmt-
            Slot #2, PowerLimit 25.000W; Interlock- NoCompl-
lid10eiger1:~ # lspci -s 0:03.0 -vvv | grep Slot
    Capabilities: [90] Express (v2) Root Port (Slot+), MSI 00
        LnkSta: Speed 5GT/s, Width x8, TrErr- Train- SlotClk+ DLActive+ BWMgmt+ ABWMgmt-
            Slot #1, PowerLimit 25.000W; Interlock- NoCompl-

This means that:

Adapter Slot
0000:02:00.x 2
0000:05:00.x 1

So we must force the following association:

PCI-e Device Network Device
0000:02:00.0 eth2
0000:02:00.1 eth3
0000:05:00.0 eth4
0000:05:00.1 eth5

This is obtained by the following udev network rules configuration:

lid10eiger1:~ # cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.

Reboot and verify that the association is OK:

IP assignments

Assign the following addresses to the Eiger interfaces:

Network Device Function IP Address
eth2 Top-Half Control 192.168.11.1
eth3 Top-Half Data 192.168.12.1
eth4 Bottom-Half Control 192.168.13.1
eth5 Bottom-Half Data 192.168.12.1

For the 10 Gigabit data interfaces, we force:

  • MTU 9000
  • Rx adaptive interrupt moderation cycle of 100 usecs: /sbin/ethtool -C ethX rx-usecs 100
  • Rx ring buffer size of 4096 entries: /sbin/ethtool -G ethX rx 4096

The resulting /etc/network/interfaces file is:

Modify nsswitch.conf to first look at /etc/hosts when resolving names:

lid10eiger1:~ # cat /etc/nsswitch.conf
# /etc/nsswitch.conf
...
hosts:          files dns [NOTFOUND=return] mdns4_minimal mdns4
...

DHCP configuration

Install DHCP server software:

# as root
lid10eiger1:~ # apt-get install isc-dhcp-server
...
[FAIL] Starting ISC DHCP server: dhcpd[....] check syslog for diagnostics. ... failed!
 failed!
invoke-rc.d: initscript isc-dhcp-server, action "start" failed.
ldegjfrau1:~ # apt-get install isc-dhcp-server

Define the dynamic addresses and Eiger MAC/name relations:

lid10eiger1:~ # cat /etc/dhcp/dhcpd.conf
...
option domain-name "esrf.fr";
option domain-name-servers dns1.esrf.fr, dns2.esrf.fr;
...
# This is a very basic subnet declaration.

Eiger calibration development: Seaborn and Spyder

The seaborn Python module and the spyder IDE for are used by Eiger calibration development (Erik Frojdh). First seaborn:

# as blissadm
lid10eiger1:~ % (. blissrc && pip install seaborn)
...

Then install spyder:

# as root
lid10eiger1:/users/blissadm # apt-get install spyder
...

Configure spyder to use the BLISS python:

# as opid00
lid10eiger1:~ % (. blissrc && spyder)

and go to ‘Tools -> Preferences -> Console -> Advanced Settings -> Python executable’ and set:

Path to Python interpreter executable binary /users/blissadm/lib/virtualenvs/bliss/bin/python

Detector software and development account: opid00

Define the Eiger software home

Add the eiger.sh entry in the system-wide Bash login setup scripts:

# as root
lid10eiger1:~ # cat /etc/profile.d/eiger.sh
EIGER_HOME=~opid00
export EIGER_HOME

Eiger environment setup

Create eiger_setup.sh, oriented to prepare the Eiger environment. In the beginning it just contains the BLISS environment:

# as opid00
lid10eiger1:~ % cat eiger_setup.sh
# Setup the Eiger data acquisition environment

# include the BLISS environment
. blissrc

and include it in the .bash_profile so it is executed at every login shell:

lid10eiger1:~ % tail -n 3 .bash_profile

# include the PSI/Eiger environment
. ${EIGER_HOME}/eiger_setup.sh

git-sig Bash helper

Add the git-sig Bash helper for authoring future commits:

lid10eiger1:~ % tail -n 22 .bashrc

# Signature: from dev-gitlab dot_bashrc

read_esrf_3612()
{
    echo $1 | nc 160.103.180.14 3612
}

git-sig()
{
    read_esrf=$(read_esrf_3612 $1)
    if [ "${read_esrf}" != "NO USER" ]; then
        GIT_AUTHOR_NAME=$(echo "${read_esrf}" | cut -d' ' -f4- | sed 's/"//g')
        GIT_AUTHOR_EMAIL="$1@esrf.fr"
    else
        GIT_AUTHOR_NAME="$1@esrf.fr"
        GIT_AUTHOR_EMAIL="$1@esrf.fr"
    fi

    export GIT_AUTHOR_NAME GIT_AUTHOR_EMAIL
    echo "Now git will use \"$GIT_AUTHOR_NAME\" to commits until SHELL ends"
}

Logout from opid00 and re-login so changes are taken into account for next steps.

...
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % git fetch --all
...

Eiger software: slsDetectorPackage

The slsDetectorPackage is in turn a submodule of the Lima/camera/slsdetector plugin:

# as opid00
(bliss) lid10eiger1:~ % cd ${LIMA_DIR}/camera/slsdetector
(bliss) lid10eiger1:Lima/camera/slsdetector % git submodule init
Submodule 'slsDetectorPackage' (git://github.com/esrf-bliss/slsDetectorPackage.git) registered for path 'slsDetectorPackage'
(bliss) lid10eiger1:Lima/camera/slsdetector % git submodule update
...
(bliss) lid10eiger1:Lima/camera/slsdetector % cd slsDetectorPackage
(bliss) lid10eiger1:camera/slsdetector/slsDetectorPackage % git remote rename origin github.bliss
(bliss) lid10eiger1:camera/slsdetector/slsDetectorPackage % git remote add github.slsdetectorgroup \
    git://github.com/slsdetectorgroup/slsDetectorPackage.git
(bliss) lid10eiger1:camera/slsdetector/slsDetectorPackage % git fetch --all
...

Lima compilation

Compile Lima, including slsDetectorPackage using CMake:

(bliss) lid10eiger1:~ % cd ${LIMA_DIR}
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % cp scripts/config.txt_default scripts/config.txt
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % echo "CMAKE_BUILD_TYPE=RelWithDebInfo" >> scripts/config.txt
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % mkdir -p ${LIMA_DIR}/install/python
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % ./install.sh \
    --install-prefix=${LIMA_DIR}/install \
    --install-python-prefix=${LIMA_DIR}/install/python \
    slsdetector sps-image gldisplay edfgz python pytango-server tests
...

Build the documentation:

(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % make -C docs html
...

Add Lima to the PATH, LD_LIBRARY_PATH and PYTHONPATH environment variables in eiger_setup.sh:

(bliss) lid10eiger1:~ % tail -n 6 eiger_setup.sh

LIMA_DIR=${SLS_DETECTORS}/Lima
PATH=${LIMA_DIR}/install/bin:${PATH}
LD_LIBRARY_PATH=${LIMA_DIR}/install/lib:${LD_LIBRARY_PATH}
PYTHONPATH=${LIMA_DIR}/install/python:${PYTHONPATH}
export LIMA_DIR PATH LD_LIBRARY_PATH PYTHONPATH

eigerDetectorServer and detector firmwares

If necessary, the eigerDetectorServer corresponding to the installed slsDetectorPackage version must be copied into the modules embedded Linux. Please refer to Installation of PSI/Eiger embedded server and firmwares

Test the slsDetectorSoftware and Lima

Logout and re-login as opid00, so the previous changes can be tested. First, test the ‘slsDetectorGui’:

(bliss) lid10eiger1:~ % start_eiger_gui
...

One xterm per Receiver (half-module) window should appear. Accept the message box acknowleging the detector configuration parameters, and the GUI will open. Wait for few seconds until a message box pops out asking to activate the high voltage; answer No. In the GUI, disable the File Name check box and press Start for a single acquisition. A frame should be taken.

Finally, test the Lima plugin without and with CtControl instantiation:

(bliss) lid10eiger1:~ % cd ${LIMA_DIR}
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % rm -f /tmp/eiger.edf && \
                                                build/camera/slsdetector/test/test_slsdetector -c ${EIGER_CONFIG}
...
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % mkdir -p /nobackup/lid10eiger12/data/eiger/lima
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % ln -s /nobackup/lid10eiger12/data/eiger/lima data
(bliss) lid10eiger1:~/esrf/sls_detectors/Lima % rm -f data/img*.edf && \
                                                python camera/slsdetector/test/test_slsdetector_control.py -c ${EIGER_CONFIG}
...

Clean the shared memory segments used by the SlsDetector library, so thay can be re-created by opid10:

# as opid00
(bliss) lid10eiger1:~ % for m in $(ipcs -m | grep '^0x000016' | awk '{print $2}'); do \
                            ipcrm -m ${m}; \
                        done

Setup opid10 account

Include the Eiger environment at login:

# as opid10
lid10eiger1:~ % tail -n 3 .bash_profile

# include the PSI/Eiger environment
. ${EIGER_HOME}/eiger_setup.sh

Install Lima Python Tango software in blissadm

Install the following packages with Blissinstaller:

  • Control/Driver/bliss_drivers: needed for blisspipe
  • Control/Taco/bliss_dserver
  • Tango/Server/LimaCCDs-Simulator:
    • Python/Modules/PyLimaCore
    • Python/MOdules/PyLimaSimulator
    • Tango/Server/LimaCCDs-common
  • Control/Tango/Applications/Jive

Configure the driver infrastructure by calling bliss_drivers config:

# as blissadm
lid10eiger1:~ % bliss_drivers config
Root Password:
Copying /users/blissadm/applications/bliss_drivers/Esrfmap/60-esrf.rules to /etc/udev/rules.d/60-esrf.rules
Starting blisspipe ...

Apply all the suggestions and save before quiting.

Include the Lima libraries and modules in the BLISS_LIB_PATH and PYTHONPATH, respectively:

# as blissadm
lid10eiger1:~ % . ${EIGER_HOME}/eiger_setup.sh
(bliss) lid10eiger1:~ % blissrc -a BLISS_LIB_PATH ${LIMA_DIR}/install/lib
(bliss) lid10eiger1:~ % blissrc -a PYTHONPATH ${LIMA_DIR}/install/python

Rename the Lima installed directories so they are no longer visible, and create the necessary symbolic links:

# as blissadm
(bliss) lid10eiger1:~ % cd ~/python/bliss_modules
(bliss) lid10eiger1:~/python/bliss_modules % mv Lima Lima-pack
(bliss) lid10eiger1:~/python/bliss_modules % cd ~/applications
(bliss) lid10eiger1:~/applications % mv LimaCCDs LimaCCDs-pack
(bliss) lid10eiger1:~/python/bliss_modules % cd ~/server/src
(bliss) lid10eiger1:~/server/src % mv LimaCCDs LimaCCDs-pack
(bliss) lid10eiger1:~/server/src % ln -s ${LIMA_DIR}/install/bin/LimaCCDs

Lima Python Tango server configuration in blissadm

Use jive server wizard to add the Lima Python Tango device server to the Tango database:

(bliss) lid10eiger1:~ % jive > /dev/null 2>&1 &

Define the server LimaCCDs/eiger500k and include it in the dserver local database:

# as blissadm
lid10eiger1:~ % cat ~/local/daemon/config/device_servers
[LimaCCDs]
*eiger500k
# as opid10
(bliss) lid10eiger1:~ % bliss_dserver -fg start LimaCCDs
Starting: LimaCCDs/eiger500k

Add LimaCCDs and SlsDetector class devices.

LimaCCDs/eiger500k/DEVICE/LimaCCDs id10/limaccds/eiger500k
id10/limaccds/eiger500k->LimaCameraType SlsDetector

16,0xfff,0xfff,0xfff,0xfff,0xfff,0xfff
32,0xfff,0xfff,0xfff,0xfff,0xfff,0xfff

Note

in order to perform high frame rate acquisitions, the CPU affinity must be fixed for the following tasks:

  • Receiver listeners
  • Receiver writers
  • Lima processing threads
  • OS processes
  • Net-dev group #1 packet dispatching
  • Net-dev group #2 packet dispatching
  • ...

The previous example is based on a dual 6-core CPUs backend (12 cores). After the data acquisition finishes the Lima processing threads will run also on the CPUs assigned to listeners and writers (0xffe), that is 11 cores in total, which is used for setting the NbProcessingThreads. Please note that there are two network groups and four pixel_depth->cpu_affinity settings (4-, 8-, 16- and 32-bit), each one represented by a line in a multi-line string array.

Finally, configure opid10 as the default DSERVER_USER, which is used by the dserver_daemon

# as blissadm
lid10eiger1:~ % grep DSERVER_USER local/BLISS_ENV_VAR || \
                     echo 'DSERVER_USER=opid10 export DSERVER_USER' >> local/BLISS_ENV_VAR

and restart the blcontrol subsystem:

# as root
lid10eiger1:~ # service blcontrol stop
 BL control ...
...
lid10eiger1:~ # service blcontrol start
 BL control ...
...

Note

the latest version of the daemon_adm package allows the propagation of the real-time priority capabilities configured as resource limits, so it is safe to start the server through the dserver remote utility. If the command *bliss_dserver start* is used, start the server in background and avoid *-fg* option, so the LimaCCDs process is decoupled from the terminal, reducing the risks of CPU blocking.
