Abstract: In an embodiment, a method includes sharing, via a publication-subscription (pub-sub) bus, an unaddressed message between a plurality of agents. The unaddressed message includes a program counter pointing to a first instruction of a program written in a programming language. The method also includes determining, by each respective agent of the plurality of agents, whether the respective agent can perform the instruction and, in response to a first agent of the plurality of agents determining that the first agent can perform the instruction, consuming, by the first agent, the unaddressed message. The method further includes removing, by the first agent, the unaddressed message from the bus, performing, by the first agent, the instruction, adding, by the first agent, one to the program counter, and posting, by the first agent, a response to the pub-sub bus for further processing of the program.
