Abstract: A device receives program code, and receives size/type information associated with inputs to the program code. The device determines, prior to execution of the program code and based on the input size/type information, a portion of the program code that is executable by a graphical processing unit (GPU), and determines, prior to execution of the program code and based on the input size/type information, a portion of the program code that is executable by a central processing unit (CPU). The device compiles the GPU-executable portion of the program code to create a compiled GPU-executable portion of the program code, and compiles the CPU-executable portion of the program code to create a compiled CPU-executable portion of the program code. The device provides, to the GPU for execution, the compiled GPU-executable portion of the program code, and provides, to the CPU for execution, the compiled CPU-executable portion of the program code.

Abstract: A device may include one or more processors. The device may receive program code that identifies operations to be performed with regard to a data set to determine an output value. The device may identify a plurality of read operations corresponding to the operations. The plurality of read operations may be performed to obtain respective inputs of the operations. The device may generate a first data structure that identifies the operations and the plurality of read operations. The device may identify two or more operations, of the operations, that receive a particular input. The device may generate a second data structure that includes a combined operation. The combined operation may be generated based on the two or more operations, and may be associated with fewer read operations than the two or more operations. The device may determine the output value based on the second data structure.

Abstract: A method and system is disclosed for providing a distributed technical computing environment for distributing technical computing tasks from a technical computing client to technical computing workers for execution of the tasks on one or more computers systems. Tasks can be defined on a technical computing client, and the tasks organized into jobs. The technical computing client can directly distribute tasks to one or more technical computing workers. Furthermore, the technical computing client can submit tasks, or jobs comprising tasks, to an automatic task distribution mechanism that distributes the tasks automatically to one or more technical computing workers providing technical computing services. The technical computing worker performs technical computing of tasks and the results of the execution of tasks may be provided to the technical computing client.

Abstract: A device initiates a technical computing environment (TCE), and receives, via the TCE, a program command that permits the TCE to access a graphical processing unit that is remote to the device, where the program command permits the TCE to seamlessly transfer data to the remote GPU. The device transforms, via the TCE, the program command into a program command that is executable by the remote GPU, and provides the transformed program command to the remote GPU for execution. The device also receives, from the remote GPU, one or more results associated with execution of the transformed program command by the remote GPU, and utilizes the one or more results via the TCE.
