Patent application number | Description | Published |
20090119676 | Virtual heterogeneous channel for message passing - A technique includes using a virtual channel between a first process and a second process to communicate messages between the processes. Each message contains protocol data and user data. All of the protocol data is communicated over a first channel associated with the virtual channel, and the user data is selectively communicated over at least one other channel associated with the virtual channel. | 05-07-2009 |
20090129277 | Automatic tuning of communication protocol performance - A method or device may optimize applications on a parallel computing system using protocols such as Message Passing Interface (MPI). Environment variables data may be used as well as a test kernel of an application to optimize communication protocol performance according to a set of predefined tuning rules. The tuning rules may specify the output parameters to be optimized, and may include a ranking or hierarchy of such output parameters. Optimization may be achieved through use of a tuning unit, which may execute the test kernel on the parallel computing system, and may monitor the output parameters for a series of input parameters. The input parameters may be varied over a range of values and combinations. Input parameters corresponding to optimized output parameters may stored for future use. This information may be used to adjust the application's communication protocol performance “on the fly” by changing the input parameters for a given usage scenario. | 05-21-2009 |
20090254920 | Extended dynamic optimization of connection establishment and message progress processing in a multi-fabric message passing interface implementation - In one embodiment, the present invention includes a system that can optimize message passing by, at least in part, automatically determining a minimum number of fabrics and virtual channels to be activated to handle pending connection requests and data transfer requests, and preventing processing of new connection requests and data transfer requests outside of a predetermined communication pattern.
