cudaError_t cudaGetDeviceProperties	(	struct cudaDeviceProp *	prop,
		int	device
	)

Returns in *prop the properties of device dev. The cudaDeviceProp structure is defined as:

    struct cudaDeviceProp {
        char name[256];
        size_t totalGlobalMem;
        size_t sharedMemPerBlock;
        int regsPerBlock;
        int warpSize;
        size_t memPitch;
        int maxThreadsPerBlock;
        int maxThreadsDim[3];
        int maxGridSize[3];
        size_t totalConstMem;
        int major;
        int minor;
        int clockRate;
        size_t textureAlignment;
        int deviceOverlap;
        int multiProcessorCount;
        int kernelExecTimeoutEnabled;
        int integrated;
        int canMapHostMemory;
        int computeMode;
        int concurrentKernels;
        int ECCEnabled;
        int pciBusID;
        int pciDeviceID;
        int tccDriver;
    }

where:

name[256] is an ASCII string identifying the device;
totalGlobalMem is the total amount of global memory available on the device in bytes;
sharedMemPerBlock is the maximum amount of shared memory available to a thread block in bytes; this amount is shared by all thread blocks simultaneously resident on a multiprocessor;
regsPerBlock is the maximum number of 32-bit registers available to a thread block; this number is shared by all thread blocks simultaneously resident on a multiprocessor;
warpSize is the warp size in threads;
memPitch is the maximum pitch in bytes allowed by the memory copy functions that involve memory regions allocated through cudaMallocPitch();
maxThreadsPerBlock is the maximum number of threads per block;
maxThreadsDim[3] contains the maximum size of each dimension of a block;
maxGridSize[3] contains the maximum size of each dimension of a grid;
clockRate is the clock frequency in kilohertz;
totalConstMem is the total amount of constant memory available on the device in bytes;
major, minor are the major and minor revision numbers defining the device's compute capability;
textureAlignment is the alignment requirement; texture base addresses that are aligned to textureAlignment bytes do not need an offset applied to texture fetches;
deviceOverlap is 1 if the device can concurrently copy memory between host and device while executing a kernel, or 0 if not;
multiProcessorCount is the number of multiprocessors on the device;
kernelExecTimeoutEnabled is 1 if there is a run time limit for kernels executed on the device, or 0 if not.
integrated is 1 if the device is an integrated (motherboard) GPU and 0 if it is a discrete (card) component.
canMapHostMemory is 1 if the device can map host memory into the CUDA address space for use with cudaHostAlloc()/cudaHostGetDevicePointer(), or 0 if not;
computeMode is the compute mode that the device is currently in. Available modes are as follows:
- cudaComputeModeDefault: Default mode - Device is not restricted and multiple threads can use cudaSetDevice() with this device.
- cudaComputeModeExclusive: Compute-exclusive mode - Only one thread will be able to use cudaSetDevice() with this device.
- cudaComputeModeProhibited: Compute-prohibited mode - No threads can use cudaSetDevice() with this device. Any errors from calling cudaSetDevice() with an exclusive (and occupied) or prohibited device will only show up after a non-device management runtime function is called. At that time, cudaErrorNoDevice will be returned.
concurrentKernels is 1 if the device supports executing multiple kernels within the same context simultaneously, or 0 if not. It is not guaranteed that multiple kernels will be resident on the device concurrently so this feature should not be relied upon for correctness;
ECCEnabled is 1 if the device has ECC support turned on, or 0 if not.
pciBusID is the PCI bus identifier of the device.
pciDeviceID is the PCI device (sometimes called slot) identifier of the device.
tccDriver is 1 if the device is using a TCC driver or 0 if not.

Parameters:

	prop	- Properties for the specified device
	device	- Device number to get properties for

Returns:: cudaSuccess, cudaErrorInvalidDevice
