kernel


Name:
kernel - Global properties of the simulation kernel.
Description:
 
Global properties of the simulation kernel.

Parameters:
 
The following parameters are available in the kernel status dictionary.

Time and resolution
resolution doubletype - The resolution of the simulation (in ms)
time doubletype - The current simulation time
to_do integertype - The number of steps yet to be simulated (read only)
max_delay doubletype - The maximum delay in the network
min_delay doubletype - The minimum delay in the network
ms_per_tic doubletype - The number of milliseconds per tic
tics_per_ms doubletype - The number of tics per millisecond
tics_per_step integertype - The number of tics per simulation time step
T_max doubletype - The largest representable time value (read only)
T_min doubletype - The smallest representable time value (read only)

Parallel processing
total_num_virtual_procs integertype - The total number of virtual processes
local_num_threads integertype - The local number of threads
num_processes integertype - The number of MPI processes (read only)
off_grid_spiking booltype - Whether to transmit precise spike times in MPI
communication (read only)

Connector configuration
initial_connector_capacity integertype - When a connector is first created, it starts with this
capacity (if >= connector_cutoff)
large_connector_limit integertype - Capacity doubling is used up to this limit
large_connector_growth_factor doubletype - Capacity growth factor to use beyond the limit

Random number generators
grng_seed integertype - Seed for global random number generator used
synchronously by all virtual processes to
create, e.g., fixed fan-out connections
(write only).
rng_seeds arraytype - Seeds for the per-virtual-process random
number generators used for most purposes.
Array with one integer per virtual process,
all must be unique and differ from
grng_seed (write only).

Output
data_path stringtype - A path, where all data is written to
(default is the current directory)
data_prefix stringtype - A common prefix for all data files
overwrite_files booltype - Whether to overwrite existing data files
print_time booltype - Whether to print progress information during the simulation

Network information
network_size integertype - The number of nodes in the network (read only)
num_connections integertype - The number of connections in the network
(read only, local only)

Waveform relaxation method (wfr)
use_wfr booltype - Whether to use waveform relaxation method
wfr_comm_interval doubletype - Desired waveform relaxation communication interval
wfr_tol doubletype - Convergence tolerance of waveform relaxation method
wfr_max_iterations integertype - Maximal number of iterations used for waveform relaxation
wfr_interpolation_order integertype - Interpolation order of polynomial used in wfr iterations

Miscellaneous
dict_miss_is_error booltype - Whether missed dictionary entries are treated as errors
