Abstract: Methods and apparatuses are provided for avoiding cold translation lookaside buffer (TLB) misses in a computer system. A typical system is configured as a heterogeneous computing system having at least one central processing unit (CPU) and one or more graphic processing units (GPUs) that share a common memory address space. Each processing unit (CPU and GPU) has an independent TLB. When offloading a task from a particular CPU to a particular GPU, translation information is sent along with the task assignment. The translation information allows the GPU to load the address translation data into the TLB associated with the one or more GPUs prior to executing the task. Preloading the TLB of the GPUs reduces or avoids cold TLB misses that could otherwise occur without the benefits offered by the present disclosure.

Abstract translation: 提供了用于避免计算机系统中的冷翻译后备缓冲器（TLB）未命中的方法和装置。 典型的系统被配置为具有至少一个中央处理单元（CPU）和共享公共存储器地址空间的一个或多个图形处理单元（GPU）的异构计算系统。 每个处理单元（CPU和GPU）都有独立的TLB。 当将任务从特定CPU卸载到特定GPU时，将随任务分配一起发送翻译信息。 翻译信息允许GPU在执行任务之前将地址转换数据加载到与一个或多个GPU相关联的TLB中。 GPU的预加载减少或避免了在没有本公开提供的优点的情况下可能发生的冷TLB未命中。

Abstract: A computing device is disclosed. The computing device includes an Accelerated Processing Unit (APU) including at least a first Heterogeneous System Architecture (HSA) computing device and at least a second HSA computing device, the second computing device being a different type than the first computing device, and an HSA Memory Management Unit (HMMU) allowing the APU to communicate with at least one memory. The computing task is enqueued on an HSA-managed queue that is set to run on the at least first HSA computing device or the at least second HSA computing device. The computing task is re-enqueued on the HSA-managed queue based on a repetition flag that triggers the number of times the computing task is re-enqueued. The repetition field is decremented each time the computing task is re-enqueued. The repetition field may include a special value (e.g., -1) to allow re-enqueuing of the computing task indefinitely.

Abstract: Methods, devices, and systems for transmitting data over a computer communications network are disclosed. A queue of communications commands can be pre-generated using a central processing unit (CPU) and stored in a device memory of a network interface controller (NIC). Thereafter, if a graphics processing unit (GPU) has data to communicate to a remote GPU, it can store the data in a send buffer, where the location in the buffer is pointed to by a pre-generated command. The GPU can then signal to the interface device that the data is ready, triggering execution of the pre-generated command to send the data.
