摘要： 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.

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.

摘要： 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.
摘要翻译：在计算系统中，可以通过使用分布式阵列来管理存储器，分布式阵列是局部存储器区域的全局集合。分布式阵列中的段被分配并绑定到物理内存区域。分段由分派的数据并行内核中的工作组使用，其中工作组包括一个或多个工作项。当分布式数组被声明时，可以定义分布式数组的参数。这些参数可以包括指示分布式阵列是否是持久性的（在一次并行调度期间写入分布式阵列的数据可由随后的调度中的工作项访问）或分布式阵列是否共享的指示（嵌套内核可以访问分布式阵列）。该段可能在使用后被释放。

摘要： 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.
摘要翻译：公开了一种介质，方法和装置，用于在向量处理环境中检测多余的功能调用。编译器接收包括功能的宽度偶然调用的程序代码。编译器通过确定目标计算机系统的向量宽度来创建程序代码的宽度特定可执行版本，并且如果向量宽度满足一个或多个标准，则从宽度特定的可执行文件中省略该函数。例如，如果向量宽度大于最小大小，编译器可以省略函数调用。

摘要： 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.
