Intelligent Input/Output Operation Completion Modes in a High-Speed Network

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• receive, by an application thread executing on a central processing unit in the data processing system, a first indication to enter a mode of operation;
• enter, by the application thread, the mode of operation;
• arm, by the application thread, an arm file descriptor;
• process, by the application thread, further completions that enter the completion queue until a second indication is received indicating that the mode is to be exited;
• responsive to receiving the second indication to exit the mode, exit, by the application thread, the mode of operation;
• and
• disarm, by the application thread, the arm file descriptor.

An apparatus comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• receive, by an application thread executing on a central processing unit in the data processing system, a first indication to enter a mode of operation;
• enter, by the application thread, the mode of operation;
• arm, by the application thread, an arm file descriptor;
• process, by the application thread, further completions that enter the completion queue until a second indication is received indicating that the mode is to be exited;
• responsive to receiving the second indication to exit the mode, exit, by the application thread, the mode of operation;
• and
• disarm, by the interconnect device, the arm file descriptor.
