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)

Random number generators
rng_types arraytype - Names of random number generator types
available (read only)
rng_type stringtype - Name of random number generator type used by kernel
rng_seed integertype - Seed value used as basis of seeding of all random
number generators managed by the kernel
(\f$1 leq s \leq 2^{32}-1\f$).

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
