System, device and method for interprocessor communication in a computer system

A device comprising a message passing service for providing communication services between a client application and at least one target application, wherein the message passing service comprises:

• application blocking logic operably coupled to block and unblock the client application for supporting synchronous communication services for the client application;
• asynchronous signaling logic operably coupled to notify the client application of asynchronous events for supporting asynchronous communication services for the client application;
• session control logic operably coupled to open a message passing session over a conduit to allow communications with any of a plurality of target applications that have an open message passing session on the conduit and operably coupled to close the message passing service session;
• synchronous message passing logic operably coupled to provide synchronous communication services for the client application over the message passing service session using the application blocking logic;
• and
• asynchronous message passing logic operably coupled to provide asynchronous communication services for the client application over the message passing service session using the asynchronous signaling logic;
• wherein the asynchronous message passing logic comprises asynchronous message sending logic operably coupled to send an asynchronous message to one of the at least one target applications and notify the client application via the asynchronous signaling logic upon receiving a confirmation from the one of the at least one target applications over the message passing service session.

A program product comprising a computer readable medium having embodied therein a message passing service program for providing communication services between a client application and remote target applications, the message passing service program comprising:

• application blocking logic programmed to block and unblock the client application for supporting synchronous communication services for the client application;
• asynchronous signaling logic programmed to notify the client application of asynchronous events for supporting asynchronous communication services for the client application;
• session control logic operably coupled to open a message passing session over a conduit to allow communications with any of a plurality of target applications that have an open message passing session on the conduit and operably coupled to close the message passing service session;
• synchronous message passing logic programmed to provide synchronous communication services for the client application over the message passing service session using the application blocking logic, wherein the synchronous message passing logic comprises synchronous message sending logic programmed to block the client application using the application blocking logic upon sending a synchronous message to one of the target applications over the message passing service session and unblock the client application using the application blocking logic upon receiving a confirmation from the one of the target applications over the message passing service session;
• and
• asynchronous message passing logic programmed to provide asynchronous communication services for the client application over the message passing service session using the asynchronous signaling logic.
