Operand data processing using instruction message queues

A processing device comprising:

• a message management facility configured to receive a plurality of instruction messages comprising new instruction messages that are received in a first message queue and rejected instruction messages that are received in a second message queue, each instruction message identifying a processing device element of a plurality of processing device elements of the processing device, an input port of the processing device element, and operand data for the input port of the processing device element;
• and
• a message processing facility comprising the plurality of processing device elements, the message processing facility being configured to receive a first instruction message of the plurality of instruction messages and a second instruction message of the plurality of instruction messages from the message management facility, reject and return the first instruction message to the message management facility to add the first instruction message to the second message queue in response to determining that the first instruction message cannot be accepted by the processing device element identified in the first instruction message, and retrieve the operand data for the input port of the processing device element identified in the second instruction message in response to determining that the second instruction message can be accepted by the processing device element identified in the second instruction message.

A processing system comprising a plurality of processing clusters, each processing cluster comprising:

• a message management facility configured to receive a plurality of instruction messages comprising new instruction messages that are received in a first message queue and rejected instruction messages that are received in a second message queue, each instruction message identifying a processing device element of a plurality of processing device elements of the processing cluster, an input port of the processing device element, and operand data for the input port of the processing device element;
• and
• a message processing facility comprising the plurality of processing device elements, the message processing facility being configured to receive a first instruction message of the plurality of instruction messages and a second instruction message of the plurality of instruction messages from the message management facility, reject and return the first instruction message to the message management facility to add the first instruction message to the second message queue in response to determining that the first instruction message cannot be accepted by the processing device element identified in the first instruction message, and retrieve the operand data for the input port of the processing device element identified in the second instruction message in response to determining that the second instruction message can be accepted by the processing device element identified in the second instruction message.
