Benchmark End (Memory Monitoring) (3 ports)

LoopEnd

This node provides the end of a timing block for monitoring performance of a node or nodes. It needs to be paired with a corresponding Performance Monitoring Timing Start (Memory monitoring) node. The node passes through the last iteration's occurrence of the input tables. An additional flow variable port with the following variable is added:

  • Overall Start Time
  • Overall End Time
  • Number of executions
  • Best execution time
  • Worst execution time
  • Total execution time
  • Mean execution time
Execution can be halted either by the number of executions in the loop start node being passed, or the optional timeout time (again from the loop start node) being passed.

NB The timeout will not halt intermediate node execution, only prevent a new iteration starting.

During loop execution, memory usage is monitored, and made available at an output port
