| 20110169840 | COMPUTING SYSTEM EMPLOYING A MULTI-GPU GRAPHICS PROCESSING AND DISPLAY SUBSYSTEM SUPPORTING SINGLE-GPU NON-PARALLEL (MULTI-THREADING) AND MULTI-GPU APPLICATION-DIVISION PARALLEL MODES OF GRAPHICS PROCESSING OPERATION - A computing system employing a multi-GPU graphics processing and display subsystem supporting single-GPU non-parallel (i.e. multi-tasking) and multi-GPU parallel application-division modes of graphics processing operations, in order to execute graphic commands and process graphics data (GCAD) render pixel-composited images containing graphics for display on a display device during the run-time of the multiple graphics-based applications, while managing and conserving electrical power and graphics processing resources. An automatic mode control module (AMCM) analyzes the application profiles assigned to graphics applications running on the computing system, and automatically controls the mode of operation of the multi-GPU graphics processing and display subsystem during the run-time of the multiple graphics-based applications. | 07-14-2011 |
| 20090027402 | Method of controlling the mode of parallel operation of a multi-mode parallel graphics processing system (MMPGPS) embodied within a host comuting system - A method of controlling the mode of parallel operation of a multi-mode parallel graphics processing system (MMPGPS) embodied within a host computing system having (i) host memory space (HMS) for storing one or more graphics-based applications and a graphics library for generating graphics commands and data (GCAD) during the run-time (i.e. execution) of the graphics-based application, (ii) one or more CPUs for executing said graphics-based applications, (iii) a display device for displaying images containing graphics during the execution of said graphics-based applications, and (iv) a multi-mode parallel graphics rendering subsystem supporting multiple modes of parallel operation selected from the group consisting of object division, image division, and time division and having a plurality of graphic processing pipelines (GPPLs) supporting a parallel graphics rendering process that employs one of the object division, image division and/or time division modes of parallel operation. | 01-29-2009 |
| 20080316216 | Computing system capable of parallelizing the operation of multiple graphics processing pipelines (GPPLS) supported on a multi-core CPU chip, and employing a software-implemented multi-mode parallel graphics rendering subsystem - A computing system capable of parallelizing the operation of multiple graphics processing units (GPUs) supported on external graphics cards, employing a software-implemented multi-mode parallel graphics rendering subsystem. The computing system includes (i) CPU memory space for storing one or more graphics-based applications, (ii) a multi-core GPU chip including one or more CPU-cores, a memory controller for controlling the CPU memory space, and an interconnect network, and (iii) one or more external graphics cards supporting multiple GPUs and being connected to the multi-core CPU chip by way of a data communication interface. The computing system also includes (i) one or more graphics cards supporting multiple GPUs and being connected to the multi-core CPU chip by way of a data communication interface, (ii) the multi-mode parallel graphics rendering subsystem supporting multiple modes of parallel operation, (iii) a plurality of graphic processing pipelines (GPPLs) implemented using some of the CPU-cores, and (iv) an automatic mode control module. During the run-time of the graphics-based application, the automatic mode control module automatically controls the mode of parallel operation of the MMPGRS, so that the GPUs are driven in a parallelized manner. | 12-25-2008 |
| 20080246772 | Multi-mode parallel graphics rendering system (MMPGRS) employing multiple graphics processing pipelines (GPPLS) and real-time performance data collection and analysis during the automatic control of the mode of parallel operation of said GPPLS - A multi-mode parallel graphics rendering system (MMPGRS) employing multiple graphics processing pipelines (GPPLs) and real-time performance data collection and analysis during the automatic control of the mode of parallel operation of the GPPLs. The MMPGRS supports multiple modes of parallel operation selected from the group consisting of object division, image division, and time division. The GPPLs support a parallel graphics rendering process that employs one or more of the object division, image division and/or time division modes of parallel operation in order to execute graphic commands and process graphics data, and render pixel-composited images containing graphics for display on a display device during the run-time of the graphics-based application. An automatic mode control module automatically controls the mode of parallel operation of the MMPGRS during the run-time of the graphics-based application by (i) automatically collecting performance data from at least one of the MMPGRS and the host computing system during the run-time of the graphics-based application, and (ii) automatically profiling the graphics-based application using the performance data and the analysis thereof. | 10-09-2008 |
