Please predict whether this patent is acceptable.PATENT ABSTRACT: The parallel information processing apparatus includes a plurality of nodes each including a first processor and a second processor. The first processor is configured to execute a computation process using a coefficient for a target data, computing a coefficient variation based on a result of the computation process, transferring the computed coefficient variation to the second processor and requesting the second processor to execute a transfer/receipt process. The second processor is configured to transmit the coefficient variation transferred from the first processor to another node and receive the coefficient variation computed by another node and integrate the coefficient variation transferred from the first processor and the coefficient variation computed by another node. At least one of the first processor and the second processor updates the coefficient to be used for the computation process from next time onward based on the integrated coefficient variation.
