Abstract: A method improves an execution speed of a host multi-core simulator simulating a target multi-core processor that has a hierarchical architecture including multiple corelets per core that, in turn include multiple functional units. The host multi-core simulator is implemented using multiple OS threads. The method selects layers in the hierarchical architecture to simulate on one of the OS threads, based on a shortest estimated layer execution time determined by (1.0+t/c*s)/min(c, t), wherein c is a number of cores in the simulator, t is a number of OS threads, and s is a threading overhead coefficient. The method respectively executes, from among the selected layers, a parallel simulation of the units therein that frequently communicate with each other on one of the multiple OS threads based on a communication frequency threshold, by assigning and using a respective user-level thread for each of the units from among a plurality of user-level threads.

Abstract: A method is provided for identifying a data transfer mismatch between a sender and a receiver from among units of a software simulator of a hardware processor. The simulator runs the plurality of the units which communicate with each other via First-In First-Outs (FIFOs). The method counts amounts of data the sender writes to the FIFOs and the receiver reads from the FIFOs for a given data transfer. The method avoids blocking during FIFO reading and writing operations by (i) reading dummy data by the receiver, even if the FIFOs are empty, when the receiver tries reading from the FIFOs, and (ii) discarding written data if the FIFOs are full, when the sender tries writing to the FIFOs. The method identifies mismatches in the amount of data the sender writes to the FIFOs versus the amount of data the receiver reads from the FIFOs for the given data transfer.

Abstract: A computer-implemented method, a computer program product, and a computer system for multi-sample dropout in deep neural network training. A computer creates multiple dropout samples in a minibatch, starting from a dropout layer and ending at a loss function layer in a deep neural network. At the dropout layer in the deep neural network, the computer applies multiple random masks for respective ones of the multiple dropout samples. At a fully connected layer in the deep neural network, the computer applies a shared parameter for all of the multiple dropout samples. After the loss function layer in the deep neural network, the computer calculates a final loss value, by averaging loss values of the respective ones of the multiple dropout samples.
