Collective Operations in a File System Based Execution Model

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:

• create, using a master application in the computing device, a multi-pipe synthetic file in a plurality of multi-pipe synthetic files in the MULTI-PIPE synthetic file system, wherein the master application indicates a multi-pipe operation to be performed;
• write, using the master application, a header-control block to the multi-pipe synthetic file specifying at least one of a multi-pipe synthetic file system name, a message type, a message size, a specific destination, or a specification of the multi-pipe operation by writing to a specific offset;
• open, using at least one other application in the plurality of applications participating in the group communications, the multi-pipe synthetic file in the MULTI-PIPE synthetic file system;
• signal, using the MULTI-PIPE synthetic file system, a MULTI-PIPE file system module in an operating system of the multi-pipe operation;
• and
• implement, using the MULTI-PIPE file system module, the multi-pipe operation as identified by the master application, wherein the master application and the at least one other application in the group communication either read or write operation messages to the multi-pipe synthetic file, wherein the messages are signaled to the MULTI-PIPE files system module, and wherein the MULTI-PIPE synthetic file system module performs an appropriate action based on the mode identified by the master application.

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:
• create, using a master application in the apparatus, a multi-pipe synthetic file in a plurality of multi-pipe synthetic files in the MULTI-PIPE synthetic file system, wherein the master application indicates a multi-pipe operation to be performed;
• write, using the master application, a header-control block to the multi-pipe synthetic file specifying at least one of a multi-pipe synthetic file system name, a message type, a message size, a specific destination, or a specification of the multi-pipe operation by writing to a specific offset;
• open, using at least one other application in the plurality of applications participating in the group communications, the multi-pipe synthetic file in the MULTI-PIPE synthetic file system;
• signal, using the MULTI-PIPE synthetic file system, a MULTI-PIPE file system module in an operating system of the multi-pipe operation;
• and
• implement, using the MULTI-PIPE file system module, the multi-pipe operation as identified by the master application, wherein the master application and the at least one other application in the group communication either read or write operation messages to the multi-pipe synthetic file, wherein the messages are signaled to the MULTI-PIPE files system module, and wherein the MULTI-PIPE synthetic file system module performs an appropriate action based on the mode identified by the master application.
