Utilization-based mapping for three dimensional analog in-memory computing

A computer implemented method for balancing utilization of tiles in an analog in-memory computing system, comprising:

• identifying, by a computer processor, a plurality of tiles in the analog in-memory computing system;
• receiving, by the computer processor, a plurality of layers in a neural network being processed by the analog in-memory computing system;
• defining, by the computer processor, a number of operations for each layer in the plurality of layers;
• assigning a utilization rate to each layer;
• determining, by the computer processor, a target equalized utilization rate based on the identified plurality of tiles;
• and
• assigning the layers to the plurality of tiles, by the computer processor, wherein a first utilization rate of a first tile is balanced relative to a second utilization rate of a second tile in the analog in-memory computing system.
