pulsarSimProcess

class pulsarSimProcess : public kotekan::Stage

pulsarSimProcess Simulates packets used for testing the transmission code

This is a Kotekan stage that simulated the VDIF headers for the pulsar transmission code. Presently this stage simulates just the headers and this is enough for current level of testing This stage is coded to simulate packets for all the 10 beams In oreder to map the packets conviently to the L0 nodes the frequency ids are derived from the hostname. The node IP address is derived by parsing the hostname.

Todo:

simulated random data, this will need more CPU resorces not requied for present testing

Buffers

• out_buf The kotkean buffer to hold the packets to be transmitted to pulsar nodes

  • Format: Array of unsigned char.

  • Metadata: none
