摘要： A processor-implemented method with data loading includes: dividing a training data set into a plurality of subsets based on sizes of a plurality of data files included in the training data set; loading, from each of the plurality of subsets, a portion of data files in the subset to a plurality of processors based on a proportion of a number of data files of the plurality of subsets in the subset and a batch size of distributed training; and reallocating, based on sizes of data files loaded to processors in a same group among the plurality of processors, the loaded data files to the processors in the same group.

摘要： A processor-implemented method with data loading includes: based on sizes of a plurality of data files in a training dataset, dividing the training dataset into a plurality of sub-sets; loading some data files in each sub-set into a plurality of processors; determining a packing combination of one or more data files loaded to processors in a same group among the plurality of processors, based on a ratio of a number of data files between the plurality of sub-sets and a batch size of distributed training; determining packed data files by packing the one or more data files according to the packing combination; and reallocating the packed data files to the processors in the same group.

摘要： A neural network operation apparatus includes: a receiver configured to receive a first input feature map; a controller configured to control multiplier-accumulators (MACs) included in a first MAC array; and a first operation engine comprising the first MAC array and configured to process the first input feature map based on the MACs of which operation states are controlled.
