Abstract
Methods and systems for multiplying a matrix and a vector are described. In an example, the vector may be partitioned into a plurality of vector partitions. The matrix may be partitioned into a plurality of matrix partitions. A plurality of threads may be scheduled to multiply each matrix partition with corresponding vector partition to determine intermediate elements. Intermediate elements determined by each thread may be stored in a local buffer assigned to the corresponding thread. Intermediate elements may be copied from a particular buffer to a memory in response to the particular buffer being full. Upon completion of the plurality of threads, the intermediate elements copied to the memory may be aggregated to generate an output vector that may be a result of multiplication between the matrix and the vector.
