Bases: spinnman.processes.abstract_multi_connection_process.AbstractMultiConnectionProcess

How to send messages to set router timeouts. These messages need to be sent to cores running the extra monitor binary.

Note

SCAMP sets wait2 to zero by default!

Note

Timeouts are specified in a weird floating point format. See the SpiNNaker datasheet for details.

Parameters:
  • next_connection_selector (AbstractMultiConnectionProcessConnectionSelector) – How to choose the connection.
  • n_retries (int) – The number of retries of a message to use. Passed to SCPRequestPipeLine
  • timeout (float) – The timeout, in seconds. Passed to SCPRequestPipeLine
  • n_channels (int) – The maximum number of channels to use when talking to a particular SCAMP instance. Passed to SCPRequestPipeLine
  • intermediate_channel_waits (int) – The maximum number of outstanding message/reply pairs to have on a particular connection. Passed to SCPRequestPipeLine
set_wait1_timeout(mantissa, exponent, core_subsets)[source]

The wait1 timeout is the time from when a packet is received to when emergency routing becomes enabled.

Parameters:
  • mantissa (int) – Timeout mantissa (0 to 15)
  • exponent (int) – Timeout exponent (0 to 15)
  • core_subsets (CoreSubsets) – Where the extra monitors that manage the routers are located.
set_wait2_timeout(mantissa, exponent, core_subsets)[source]

The wait2 timeout is the time from when a packet has emergency routing enabled for it to when it is dropped.

Parameters:
  • mantissa (int) – Timeout mantissa (0 to 15)
  • exponent (int) – Timeout exponent (0 to 15)
  • core_subsets (CoreSubsets) – Where the extra monitors that manage the routers are located.
