A method for executing a plurality of data-parallel threads of a processing logic on a processor core includes grouping the plurality of data-parallel threads into one or more workgroups, associating a first workgroup from the one or more workgroups with an operating system thread on the processor core, and configuring threads from the first workgroup as user-level threads within the operating system thread. In an example, a method enables the execution of GPU-kernels that has been previously configured for a GPU, to execute on a CPU such as a multi-core CPU. The mapping of the numerous data-parallel threads to the CPU is done in such a manner as to reduce the number of costly operating system threads instantiated on the CPU, and to enable efficient debugging.

A device receives input that includes definitions of components of a computational pipeline, where the components include one or more buffers, one or more kernels, and one or more stages within a control graph. The device generates, based on the input, kernel signatures for a graphics processor, where the kernel signatures compile into an executable streaming program for the computational pipeline. The device also generates, based on the input, host-side runtime code to execute the streaming program.

A medium and method is disclosed for compiling vector programs. A compiler receives program code that includes a function invocation. The compiler determines the vector width of a target computer system and creates a width-specific executable version of the program code by mapping the function invocation to a width-specific implementation of the function. The width-specific implementation corresponds to the vector width of the target computer system.

A medium, method, and apparatus are disclosed for eliding superfluous function invocations in a vector-processing environment. A compiler receives program code comprising a width-contingent invocation of a function. The compiler creates a width-specific executable version of the program code by determining a vector width of a target computer system and omitting the function from the width-specific executable if the vector width meets one or more criteria. For example, the compiler may omit the function call if the vector width is greater than a minimum size.

Method, system, and computer program product embodiments for synchronizing workitems on one or more processors are disclosed. The embodiments include executing a barrier skip instruction by a first workitem from the group, and responsive to the executed barrier skip instruction, reconfiguring a barrier to synchronize other workitems from the group in a plurality of points in a sequence without requiring the first workitem to reach the barrier in any of the plurality of points.

A computer system is provided for compiling program code and a method for compiling program code by a processor. The method, for example, includes, but is not limited to, receiving, by the processor, the program code and compiling, by the processor, the program code, wherein the processor, when compiling the program code, parses the program code and assigns a default address space qualifier to each member functions without a defined address space qualifier and, when the member function is used, infers an address space for each default address qualifier based upon how the respective member function is being used.

A system, method, and computer program product are provided for improving resource utilization of multithreaded applications. Rather than requiring threads to block while waiting for data from a channel or requiring context switching to minimize blocking, the techniques disclosed herein provide an event-driven approach to launch kernels only when needed to perform operations on channel data, and then terminate in order to free resources. These operations are handled efficiently in hardware, but are flexible enough to be implemented in all manner of programming models.

In a computing system, memory may be managed by using a distributed array, which is a global set of local memory regions. A segment in the distributed array is allocated and is bound to a physical memory region. The segment is used by a workgroup in a dispatched data parallel kernel, wherein a workgroup includes one or more work items. When the distributed array is declared, parameters of the distributed array may be defined. The parameters may include an indication whether the distributed array is persistent (data written to the distributed array during one parallel dispatch is accessible by work items in a subsequent dispatch) or an indication whether the distributed array is shared (nested kernels may access the distributed array). The segment may be deallocated after it has been used.
