Typedef Documentation

typedef struct GroupNeuromodulatorInfo GroupNeuromodulatorInfo_t

The struct is used in test suite only. CARLsim API call provides a getter function CARLsim::getGroupNeuromodulatorInfo() for retrieving neuromodulator information of a group. A developer can write his/her test cases to test the neuromodulator parameters

See also: CARLsim::getGroupNeuromodulatorInfo()

typedef struct GroupSTDPInfo GroupSTDPInfo_t

The struct is used in test suite only. CARLsim API call provides a getter function CARLsim::getGroupSTDPInfo() for retrieving STDP related information of a group. A developer can write his/her test cases to test the STDP parameters

Enumeration Type Documentation

enum carlsimState_t

A CARLsim simulation goes through the following states: CONFIG_STATE configuration state, where the neural network is configured SETUP_STATE setup state, where the neural network is prepared for execution RUN_STATE run state, where the simulation is executed Certain methods can only be called in certain states. Check their documentation to see which method can be called in which state.

Certain methods perform state transitions. CARLsim::setupNetwork will change the state from CONFIG_STATE to SETUP_STATE. The first call to CARLsim::runNetwork will change the state from SETUP_STATE to RUN_STATE.

Enumerator
CONFIG_STATE	configuration state, where the neural network is configured
SETUP_STATE	setup state, where the neural network is prepared for execution and monitors are set
RUN_STATE	run state, where the model is stepped

Definition at line 242 of file carlsim_datastructures.h.

enum integrationMethod_t

CARLsim supports different integration methods. Currently available:

FORWARD_EULER: Forward-Euler (aka Euler method). Most basic explicit method for numerical integration of ODEs. Suggest time step of 0.5ms or lower for stability. RUNGE_KUTTA4: Fourth-order Runge-Kutta (aka classical Runge-Kutta, aka RK4). Suggest time step of 0.1ms or lower.

Enumerator
FORWARD_EULER
RUNGE_KUTTA4
UNKNOWN_INTEGRATION

Definition at line 127 of file carlsim_datastructures.h.

enum loggerMode_t

The logger mode defines where to print all status, error, and debug messages. Several predefined modes exist (USER, DEVELOPER, SHOWTIME, SILENT). However, the user can also set each file pointer to a location of their choice (CUSTOM mode). The following logger modes exist: USER User mode, for experiment-oriented simulations. Errors and warnings go to stderr, status information goes to stdout. Debug information can only be found in the log file. DEVELOPER Developer mode, for developing and debugging code. Same as user, but additionally, all debug information is printed to stdout. SHOWTIME Showtime mode, will only output warnings and errors. SILENT Silent mode, no output is generated. CUSTOM Custom mode, the user can set the location of all the file pointers.

The following file pointers exist: fpOut_ where CARLSIM_INFO messages go fpErr_ where CARLSIM_ERROR and CARLSIM_WARN messages go fpDeb_ where CARLSIM_DEBUG messages go fpLog_ typically a log file, where all of the above messages go

The file pointers are automatically set to different locations, depending on the loggerMode:

*          |    USER    | DEVELOPER  |  SHOWTIME  |   SILENT   |  CUSTOM
* ---------|------------|------------|------------|------------|---------
* fpOut_   |   stdout   |   stdout   | /dev/null  | /dev/null  |    ?
* fpErr_   |   stderr   |   stderr   |   stderr   | /dev/null  |    ?
* fpDeb_   | /dev/null  |   stdout   | /dev/null  | /dev/null  |    ?
* fpLog_   | debug.log  | debug.log  | debug.log  | /dev/null  |    ?
*

Location of the debug log file can be set in any mode using CARLsim::setLogDebugFp. In mode CUSTOM, the other file pointers can be set using CARLsim::setLogsFp.

Enumerator
USER	User mode, for experiment-oriented simulations.
DEVELOPER	Developer mode, for developing and debugging code.
SHOWTIME	Showtime mode, will only output warnings and errors.
SILENT	Silent mode, no output is generated.
CUSTOM	Custom mode, the user can set the location of all the file pointers.
UNKNOWN_LOGGER

enum neuromodulator_t

To monitor concentration of neuromodulator through GroupMonitor following flags can be used NM_DA Dopamine NM_5HT Serotonin NM_ACh Acetylcholine NM_NE Noradrenaline

Enumerator
NM_DA	dopamine
NM_5HT	serotonin
NM_ACh	acetylcholine
NM_NE	noradrenaline
NM_UNKNOWN	unknown type

Definition at line 201 of file carlsim_datastructures.h.

enum simMode_t

CARLsim supports execution either on standard x86 central processing units (CPUs) or off-the-shelf NVIDIA GPUs.

When creating a new CARLsim object, you can choose from the following: CPU_MODE: run on a single CPU core GPU_MODE: run on a single GPU card

When running GPU mode on a multi-GPU system, you can specify on which CUDA device to establish a context (ithGPU, 0-indexed) when you create a new CpuSNN object. The simulation mode will be fixed throughout the lifetime of a CpuSNN object.

Enumerator
CPU_MODE	model is run on a single CPU core
GPU_MODE	model is run on a single GPU card
UNKNOWN_SIM

Definition at line 108 of file carlsim_datastructures.h.

enum spikeMonMode_t

SpikeMonitors can be run in different modes: COUNT: Will collect only spike count information (such as number of spikes per neuron), not the explicit spike times. COUNT mode cannot retrieve exact spike times per neuron, and is thus not capable of computing spike train correlation etc. AER: Will collect spike information in AER format (will collect both neuron IDs and spike times).

Enumerator
COUNT	mode in which only spike count information is collected
AER	mode in which spike information is collected in AER format

Definition at line 183 of file carlsim_datastructures.h.

enum stdpCurve_t

CARLsim supports different STDP curves

Enumerator
EXP_CURVE	standard exponential curve
PULSE_CURVE	symmetric pulse curve
TIMING_BASED_CURVE	timing-based curve
UNKNOWN_CURVE	unknown curve type

Definition at line 160 of file carlsim_datastructures.h.

enum stdpType_t

CARLsim supports two different flavors of STDP. STANDARD: The standard model of Bi & Poo (2001), nearest-neighbor. DA_MOD: Dopamine-modulated STDP, nearest-neighbor.

Enumerator
STANDARD	standard STDP of Bi & Poo (2001), nearest-neighbor
DA_MOD	dopamine-modulated STDP, nearest-neighbor
UNKNOWN_STDP

Definition at line 144 of file carlsim_datastructures.h.

enum updateInterval_t

CARLsim supports different update frequency for weight update and weightChange update INTERVAL_10MS: the update interval will be 10 ms, which is 100Hz update frequency INTERVAL_100MS: the update interval will be 100 ms, which is 10Hz update frequency INTERVAL_1000MS: the update interval will be 1000 ms, which is 1Hz update frequency

Enumerator
INTERVAL_10MS	the update interval will be 10 ms, which is 100Hz update frequency
INTERVAL_100MS	the update interval will be 100 ms, which is 10Hz update frequency
INTERVAL_1000MS	the update interval will be 1000 ms, which is 1Hz update frequency
