Inter-thread data communications in a computer processor

An apparatus for inter-thread data communications, the apparatus comprising:

• a computer processor comprising multiple hardware threads of execution;
• and
• an inter-thread communications controller operatively coupling the hardware threads for data communications and capable of:
• registering, controller responsive to one or more RECEIVE opcodes, one or more receiving threads executing the RECEIVE opcodes;
• receiving, from a SEND opcode of a sending thread by the inter-thread communications controller, specifications of a number of derived messages to be sent to receiving threads and a base value;
• generating, by the inter-thread communications controller, the derived messages, incrementing the base value once for each registered receiving thread so that each derived message comprises a single integer as a separate increment of the base value;
• sending, by the inter-thread communications controller to each registered receiving thread, a derived message;
• and
• returning, from the inter-thread communications controller to the sending thread, an actual number of derived messages received by receiving threads.

A computer program product for inter-thread data communications in a computer processor with multiple hardware threads of execution, each hardware thread operatively coupled for data communications through an inter-thread communications controller, the computer program product disposed upon a non-transitory computer readable storage medium, the computer program product comprising computer program instructions capable, when executed, of causing a computer to carry out the steps of:

• registering, by the inter-thread communications controller responsive to one or more RECEIVE opcodes, one or more receiving threads executing the RECEIVE opcodes;
• receiving, from a SEND opcode of a sending thread by the inter-thread communications controller, specifications of a number of derived messages to be sent to receiving threads and a base value;
• generating, by the inter-thread communications controller, the derived messages, incrementing the base value once for each registered receiving thread so that each derived message comprises a single integer as a separate increment of the base value;
• sending, by the inter-thread communications controller to each registered receiving thread, a derived message;
• and
• returning, from the inter-thread communications controller to the sending thread, an actual number of derived messages received by receiving threads.
