Cabinet Configuration YAML

A Cabinet Configuration YAML is used to test multiple station with one configuration file.

NOTE: Some tests fail when using this mode.

To setup a cabinet config file, you provide a list of individual station files and there names.

e.g.

stations:

  <station 1 name>: "<station 1 config file name e.g. station_1_config.yml>"
  <station 2 name>: "<station 2 config file name>"
  <station 3 name>: "<station 3 config file name>"
  <station 4 name>: "<station 4 config file name>"
  <station 5 name>: "<station 5 config file name>"
  <station 6 name>: "<station 6 config file name>"

NOTE: station names will overwrite the individual station name

Requirements

• Each station must have a different network interface, either physical or virtual.

• Each station must have no overlapping TPMs

• Each station tile_40g_subnet, must be separated by 2 * number of TPMs per station

• Each station must have a unique station id and network ports

• Stations should either use all subrack format for specifying TPMs or the tiles format not both

Virtual Network Interface

To setup a virtual network interface (macvlan) on linux, run the following commands:

sudo sysctl -w net.ipv4.conf.all.arp_ignore=1
sudo sysctl -w net.ipv4.conf.all.arp_announce=2

sudo ip link add <macvlan name> link <physical nic interface name> type macvlan
sudo ifconfig <macvlan name> <macvlan ip> netmask 255.255.255.0
sudo ip route add <macvlan ip>/32 dev <macvlan name>

Failing Tests

The following tests fail when using cabinet testing mode. Most are likely to do with issues with the DAQ.

Test Name	Error description
adc	Test fails occasionally
daq	see issue 3 in JANUS-119
channelizer	First station test passes and the rest fails
pfb	First station test passes and the rest fails
tile_beamformer	Has the error: cannot convert float Nan to integer
flagging	Has the error: segmentation fault
antenna_buffer	gets stuck and doesn’t receive any data
init_station	Expected data rate 1.34 GiB/s, received data rate 1.25 GiB/s, this is due to how python gets the data rate. Data rate captured by other means matches the 1.34 GiB/s. Happens when full 300 MHz bandwidth is tested.
channelizer_offline	TBC. New test, not yet tested in cabinet testing mode.
tile_beam_tracking	TBC. New test, not yet tested in cabinet testing mode.
independent_beams	TBC. New test, not yet tested in cabinet testing mode.
spead_tile_beam	TBC. New test, not yet tested in cabinet testing mode.
spead_station_beam	TBC. New test, not yet tested in cabinet testing mode.
spead_raw_adc	TBC. New test, not yet tested in cabinet testing mode.
spead_antenna_buffer	TBC. New test, not yet tested in cabinet testing mode.
spead_channelised	TBC. New test, not yet tested in cabinet testing mode.
