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:

lid10eiger1:~ # scp lid01eiger1:/usr/bin/getconf .


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 <<'EOF'
# valid values: userspace conservative powersave ondemand performance
# get them from cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors


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

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

Network performance

Add opid00 user:

# as root
lid10eiger1:~ # mkuser opid00

Create netperf group and add affected users to it:

lid10eiger1:~ # groupadd netperf

lid10eiger1:~ # for u in ahoms opid00 opid10; do \
    usermod -a -G netperf ${u}; \

Allow netperf users to set real-time (SCHED_RR) scheduling policy with the highest priority:

lid10eiger1:~ # cat > /etc/security/limits.d/net-performance.conf <<'EOF'
@netperf         -       rtprio 99

Compile the netdev_set_queue_cpu_affinity util, used by the SlsDetector plugin to change the network packet dispatching tasks’ CPU affinity, and install it in /usr/local/bin:

        return 0;

    gcc -Wall -o ${prog_name} ${prog_name}.c
    rm -f ${prog_name}.c

Allow netperf users to execute sudo in order to change other tasks’ CPU affinity (taskset and netdev_set_queue_cpu_affinity), to configure the network devices (ethtool and ifconfig) and start/stop system services like irqbalance (service):

lid10eiger1:~ # cat > /etc/sudoers.d/netperf <<'EOF'

cmake & libnuma-dev

Conda includes cmake, needed to compile Lima. De-install the Debian 7 package, if present, or the manually installed cmake-3.8.0:

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

lid10eiger1:~ # \

    if [ -n "${curr_cmake}" ] && [ $(dirname ${curr_cmake}) == "/usr/local/bin" ]; then
        cmake_src=$(find ~ ~opid00 -type d -name cmake-3.8.0)
        [ -n "${cmake_src}" ] && cd ${cmake_src} && su -c "make uninstall"

The same applies to libnuma-dev:

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


Xsession executes ssh-agent, which has the setgid bit set. This forces Linux to clear its LD_LIBRARY_PATH, and hence that of its descendant processes - the full X11 session. The following patch propagates the LD_LIBRARY_PATH configured at login (.bash_profile) to the X11 session:

# as root
lid10eiger1:~ # (
    [ -f ${Xsession_patch} ] || cat > ${Xsession_patch} <<'EOF'
# This file is sourced by Xsession(5), not executed.

# ensure LD_LIBRARY_PATH is propagated after ssh-agent is executed

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
             |               \-00.1
             |               \-00.1
             |               \-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
eth3 Top-Half Data
eth4 Bottom-Half Control
eth5 Bottom-Half Data

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:

lid10eiger1:~ # cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp
#   up sleep 5; /sbin/ethtool -s eth0 autoneg off speed 100 duplex full
    up sleep 5; /sbin/ethtool -s eth0 autoneg on speed 1000 duplex full

# The secondary network interface
auto eth1
allow-hotplug eth1
iface eth1 inet static

# The 10 Gbps FO network interfaces - Top half
auto eth2
allow-hotplug eth2

auto eth3

        mtu 9000
        up while /sbin/ethtool eth3 | grep 'Link detected' | grep -q no; do sleep 1; done; /sbin/ethtool -C eth3 rx-usecs 100; /sbin/ethtool -G eth3 rx 4096

# The 10 Gbps FO network interfaces - Bottom half
auto eth4
allow-hotplug eth4

auto eth5

        mtu 9000
        up while /sbin/ethtool eth5 | grep 'Link detected' | grep -q no; do sleep 1; done; /sbin/ethtool -C eth5 rx-usecs 100; /sbin/ethtool -G eth5 rx 4096

PSI/Eiger modules

Define the PSI/Eiger module IPs (data interfaces are not actually needed):

lid10eiger1:~ # cat /etc/hosts
#============= OS ====================   localhost lid10eiger1

#============= Eiger ====================
# Direct Connection - Top half  beb021
#     beb02110ge1

# Direct Connection - Bottom half  beb020
#     beb02010ge1

#============= OS ====================
# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

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!
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 "";
option domain-name-servers,;
# This is a very basic subnet declaration.

subnet netmask {

subnet netmask {

subnet netmask {

subnet netmask {

subnet netmask {

# PSI Eiger 500k detectors

host beb021 {
  hardware ethernet 00:50:c2:46:d9:2a;

host beb020 {
  hardware ethernet 00:50:c2:46:d9:28;

Specify the interfaces DHCP server will listen on:

lid10eiger1:~ # cat /etc/default/isc-dhcp-server
INTERFACES="eth2 eth4"

Reboot the computer for the changes to be applied. Verify that the dhcp server is running on the given interfaces:

lid10eiger1:~ # ps -ef | grep dhcpd | grep -v grep
root      3923     1  0 21:48 ?        00:00:00 /usr/sbin/dhcpd -q -cf /etc/dhcp/dhcpd.conf -pf /var/run/ eth2 eth4

Restart the detector, wait for 20 sec and check that the links are OK:

lid10eiger1:~ # for i in $(seq 2 5); do n="eth${i}"; ifconfig ${n} | grep UP; done

lid10eiger1:~ # ping -c 1 beb021; ping -c 1 beb020

(slsdetector) lid10eiger1:~ % \
    cd ${LIMA_DIR}/camera/slsdetector
    git submodule init
    git submodule update
    cd slsDetectorPackage
    git remote rename origin github.bliss
    git remote add github.slsdetectorgroup \
    git fetch --all

Lima compilation

Compile Lima, including slsDetectorPackage using CMake:

(slsdetector) lid10eiger1:~ % \
    cd ${LIMA_DIR}
    cp scripts/config.txt_default scripts/config.txt
    mkdir -p ${LIMA_DIR}/install/python
(slsdetector) lid10eiger1:~/esrf/sls_detectors/Lima % ./ \
    --install-prefix=${LIMA_DIR}/install \
    --install-python-prefix=${LIMA_DIR}/install/python \
    slsdetector hdf5 hdf5-bs edfgz edflz4 python pytango-server tests 2>&1

Build the documentation:

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

Add Lima to the PATH, LD_LIBRARY_PATH and PYTHONPATH environment variables in

(slsdetector) lid10eiger1:~ % cat >> <<'EOF'


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 slsdetector Lima plugin

Logout and re-login as opid00, so the previous changes can be tested. Test the Lima plugin without and with CtControl instantiation:

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

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

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

Setup opid10 account

Include the Eiger environment at login:

# as opid10
lid10eiger1:~ % cat >> .bash_profile <<'EOF'

# include the PSI/Eiger environment

    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:

(slsdetector) 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
# as opid10
(slsdetector) lid10eiger1:~ % bliss_dserver -fg start LimaCCDs
Starting: LimaCCDs/eiger500k

Add LimaCCDs and SlsDetector class devices.

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 #0 packet dispatching
  • Net-dev group #1 packet dispatching

The previous example is based on a dual 6-core CPUs backend with Hyper-Threading Technology (12 cores, 24 threads). After the data acquisition finishes the Lima processing threads will run also on the CPUs assigned to listeners and writers (0xfffffe), that is 23 cores in total, which is used for setting the NbProcessingThreads. Please note that there are three 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.


The Intel 10 Gigabit Ethernet Server Adapter has multiple hardware FIFOs per port, called queues in the OS terminology. The hardware uses a hash algorithm to dispatch packets into the active queues, which includes the source IP address. Each FIFO has an associated IRQ, so the irqbalance service activates the Receive-Side Scaling (RSS) mechanism by distributing the queues IRQ Service Routine (ISR) CPU affinity on different cores.

The destination FIFO in the Intel adapter depends on the Eiger 10 Gigabit Ethernet data interface IP, and thus the CPU where the corresponding ISR will run. ISRs have higher priority than packet dispatch tasks. If the queue IRQs are serviced by the same CPU that does the packet dispatching, the latter is affected when the frame rate is important. Care must be taken to avoid this kind of CPU conflict by having a deterministic CPU task distribution. With this aim, the Lima plugin sets not only the (network stack dispatching) Receive Packet Steering (RPS) CPU Affinity for both data interfaces eth3/eth5 but also their effective hardware FIFO ISR CPU Affinity (netdev_group CPU affinity).

Lima uses the ethtool -S command, which shows the statistics of a network device, including the bytes/packets received per FIFO, in order to determine the active FIFOs. Then it uses the files:

  • /proc/interrupts
  • /sys/class/net/<netdev>/device/msi_irqs/<irq>
  • /proc/irq/<irq>/smp_affinity_list

to find out the active device IRQs and to set their corresponding CPU affinities. If running, the irqbalance service is stopped before setting the IRQ affinity and restored during application cleanup.

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 ...


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.
