Benchmark cells

class arbor.benchmark_cell

A benchmarking cell, used by Arbor developers to test communication performance.

benchmark_cell(source, target, schedule, realtime_ratio)

Construct a benchmark cell with a single built-in source with label source; and a single built-in target with label target. The labels can be used for forming connections from/to the cell in the arbor.recipe by creating a arbor.connection.

A benchmark cell generates spikes at a user-defined sequence of time points:

• at regular intervals (using an arbor.regular_schedule)

• at a sequence of user-defined times (using an arbor.explicit_schedule)

• at times defined by a Poisson sequence (using an arbor.poisson_schedule)

and the time taken to integrate a cell can be tuned by setting the parameter realtime_ratio.

Parameters

• source – label of the source on the cell.

• target – label of the target on the cell.

• schedule – User-defined sequence of time points (choose from arbor.regular_schedule, arbor.explicit_schedule, or arbor.poisson_schedule).

• realtime_ratio – Time taken to integrate a cell, for example if realtime_ratio = 2, a cell will take 2 seconds of CPU time to simulate 1 second.
