A computing method includes: generating first partitioned matrices by partitioning the first matrix by a least common multiple of the M and the N in the row direction and by the N in the column direction; generating second partitioned matrices by partitioning the second matrix by the M in the row direction and by the least common multiple in the column direction; adding a first product of the first partitioned matrices and the second partitioned matrices to a first result matrix; transmitting the first partitioned matrices to computing elements directly connected to that computing element out of other computing elements connected to each other in a torus-like manner in the row direction; transmitting the second partitioned matrices to computing elements directly connected to that computing element out of other computing elements connected to each other in a torus-like manner in the column direction.
