Memory-mapped interface to message-passing computing systems

A method comprising:

• receiving a message at an interface via a network from a source neural network processing core of a neural network processor system,
• the message comprising message data and at least one address,
• the interface comprising a memory map
• the memory map comprising a first region corresponding to inputs to the neural network processor system and a second region corresponding to outputs from the neural network processor system,
• the interface comprising a buffer;
• and
• storing the message data in the buffer of the interface at a location,
• the at least one address corresponding to the location in the buffer.

A computer program product for interfacing a memory mapped system with a message passing system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• receiving a message at an interface via a network from a source neural network processing core of a neural network processor system,
• the message comprising message data and at least one address,
• the interface comprising a memory map
• the memory map comprising a first region corresponding to inputs to the neural network processor system and a second region corresponding to outputs from the neural network processor system,
• the interface comprising a buffer;
• and
• storing the message data in the buffer of the interface at a location,
• the at least one address corresponding to the location in the buffer.
