CUBLAS Library

CHAPTER 1The CUBLAS Librarycopies a tile of rows×cols elements from a matrix A in CPU memoryspace to a matrix B in GPU memory space. Each element requiresstorage of elemSize bytes. Both matrices are assumed to be stored incolumn‐major format, with the leading dimension (that is, the numberof rows) of source matrix A provided in lda, and the leadingdimension of destination matrix B provided in ldb. B is a devicepointer that points to an object, or part of an object, that was allocatedin GPU memory space via cublasAlloc().Return ValuesCUBLAS_STATUS_NOT_INITIALIZED if CUBLAS library was not initializedCUBLAS_STATUS_INVALID_VALUE if rows or cols < 0; or elemSize,lda, or ldb
