Functions
Algorithm Interface
CUDPP_DLL CUDPPResult	cudppScan (const CUDPPHandle planHandle, void *d_out, const void *d_in, size_t numElements)
	Performs a scan operation of numElements on its input in GPU memory (d_in) and places the output in GPU memory (d_out), with the scan parameters specified in the plan pointed to by planHandle. More...
CUDPP_DLL CUDPPResult	cudppSegmentedScan (const CUDPPHandle planHandle, void *d_out, const void *d_idata, const unsigned int *d_iflags, size_t numElements)
	Performs a segmented scan operation of numElements on its input in GPU memory (d_idata) and places the output in GPU memory (d_out), with the scan parameters specified in the plan pointed to by planHandle. More...
CUDPP_DLL CUDPPResult	cudppMultiScan (const CUDPPHandle planHandle, void *d_out, const void *d_in, size_t numElements, size_t numRows)
	Performs numRows parallel scan operations of numElements each on its input (d_in) and places the output in d_out, with the scan parameters set by config. Exactly like cudppScan except that it runs on multiple rows in parallel. More...
CUDPP_DLL CUDPPResult	cudppCompact (const CUDPPHandle planHandle, void *d_out, size_t *d_numValidElements, const void *d_in, const unsigned int *d_isValid, size_t numElements)
	Given an array d_in and an array of 1/0 flags in deviceValid, returns a compacted array in d_out of corresponding only the "valid" values from d_in. More...
CUDPP_DLL CUDPPResult	cudppReduce (const CUDPPHandle planHandle, void *d_out, const void *d_in, size_t numElements)
	Reduces an array to a single element using a binary associative operator. More...
CUDPP_DLL CUDPPResult	cudppRadixSort (const CUDPPHandle planHandle, void *d_keys, void *d_values, size_t numElements)
	Sorts key-value pairs or keys only. More...
CUDPP_DLL CUDPPResult	cudppMergeSort (const CUDPPHandle planHandle, void *d_keys, void *d_values, size_t numElements)
	Sorts key-value pairs or keys only. More...
CUDPP_DLL CUDPPResult	cudppStringSort (const CUDPPHandle planHandle, unsigned int *d_keys, unsigned int *d_values, unsigned int *stringVals, size_t numElements, size_t stringArrayLength)
	Sorts strings. Keys are the first four characters of the string, and values are the addresses where the strings reside in memory (stringVals) More...
CUDPP_DLL CUDPPResult	cudppStringSort (const CUDPPHandle planHandle, unsigned char *d_stringVals, unsigned int *d_address, unsigned char termC, size_t numElements, size_t stringArrayLength)
	Sorts strings. Keys are the first four characters of the string, and values are the addresses where the strings reside in memory (stringVals) More...
CUDPP_DLL CUDPPResult	cudppSparseMatrixVectorMultiply (const CUDPPHandle sparseMatrixHandle, void *d_y, const void *d_x)
	Perform matrix-vector multiply y = A*x for arbitrary sparse matrix A and vector x. More...

Detailed Description

Main library source file. Implements wrappers for public interface.

cudpp.cpp

Main library source file. Implements wrappers for public interface. These wrappers call application-level operators. As this grows we may decide to partition into multiple source files.
