    Abstract: A software development environment (SDE) and a method of compiling integrated source code. One embodiment of the SDE includes: (1) a parser configured to partition an integrated source code into a host code partition and a device code partition, the host code partition including a reference to a device variable, (2) a translator configured to: (2a) embed device machine code, compiled based on the device code partition, into a modified host code, (2b) define a pointer in the modified host code configured to be initialized, upon execution of the integrated source code, to a memory address allocated to the device variable, and (2c) replace the reference with a dereference to the pointer, and (3) a host compiler configured to employ a host library to compile the modified host code.

    Abstract: The present invention facilitates efficient and effective utilization of unified virtual addresses across multiple components. In one exemplary implementation, an address allocation process comprises: establishing space for managed pointers across a plurality of memories, including allocating one of the managed pointers with a first portion of memory associated with a first one of a plurality of processors; and performing a process of automatically managing accesses to the managed pointers across the plurality of processors and corresponding memories. The automated management can include ensuring consistent information associated with the managed pointers is copied from the first portion of memory to a second portion of memory associated with a second one of the plurality of processors based upon initiation of an accesses to the managed pointers from the second one of the plurality of processors.

    Abstract: Techniques are disclosed for reducing the latency between the completion of a producer task and the launch of a consumer task dependent on the producer task. Such latency exists when the information needed to launch the consumer task is unavailable when the producer task completes. Thus, various techniques are disclosed, where a task management unit initiates the retrieval of the information needed to launch the consumer task from memory in parallel with the producer task being launched. Because the retrieval of such information is initiated in parallel with the launch of the producer task, the information is often available when the producer task completes, thus allowing for the consumer task to be launched without delay. The disclosed techniques, therefore, enable the latency between completing the producer task and launching the consumer task to be reduced.
