Method and system for depth pre-processing and geometry sorting using binning hardware
Described herein are techniques for improving the effectiveness of depth culling. In a first technique, a binner is used to sort primitives into depth bins. Each depth bin covers a range of depths.

Processing the near bins first results in the depth buffer being updated, allowing fragments for the primitives in the farther bins to be culled more aggressively than if the depth binning did not occur. In a second technique, a buffer is used to initiate two-pass processing through the screen space pipeline. In the first pass, primitives are sent down to update the depth block and are then culled. The fragments are processed normally in the second pass, with the benefit of the updated depth values. |

Automatically introducing register dependencies to tests
Method, apparatus and product for automatically introducing register dependency into tests. A test template represents an abstract test scenario to be utilized for testing a target processor. The abstract test scenario requires that a value be assigned to a register. A test that implements the abstract test scenario is generated. The test is a set of instructions that are executable by the target processor. The generation of the test comprises: determining a memory address to retain the value in a memory that is accessible to the target processor; and adding to the test an instruction to load to the register the value from the memory address, whereby adding a register dependency to the test that is not required by the abstract test scenario. The test can be executed on the target processor or simulation thereof. |

Recording a trace of code execution using reserved cache lines in a cache
Recording a trace of code execution using reserved cache lines in a cache. A computing device comprises processing units and a cache. The cache includes a first plurality of cache lines that each comprise an address portion for storing a memory address within the memory device, and a value portion for storing a value associated with the memory address. The cache also includes a second plurality of reserved cache lines that store a plurality of sets of accounting bits. Each set of accounting bits comprises a plurality of accounting bits and is associated with a different cache line in the first cache lines. Each cache line in the second cache lines stores multiple of the sets of accounting bits. Stored control logic uses the plurality of sets of accounting bits in the second cache lines to track trace logging information for the first cache lines. |

Self-test during idle cycles for shader core of GPU
The disclosure describes techniques for a self-test of a graphics processing unit (GPU) independent of instructions from another processing device. The GPU may perform the self-test in response to a determination that the GPU enters an idle mode. The self-test may be based on information indicating a safety level, where the safety level indicates how many faults in circuits or memory blocks of the GPU need to be detected. |

Two node clusters recovery on a failure
Systems and methods for high availability computing systems. Systems and methods include disaster recovery of two-node computing clusters. A method embodiment commences upon identifying a computing cluster having two nodes, the two nodes corresponding to a first node and a second node that each send and receive heartbeat indications periodically while performing storage I/O operations. One or both of the two nodes detect a heartbeat failure between the two nodes, and in response to detecting the heartbeat failure, one or both of the nodes temporarily cease storage I/O operations. A witness node is accessed in an on-demand basis as a result of detecting the heartbeat failure. The witness performs a leadership election operation to provide a leadership lock to only one requestor. The leader then resumes storage I/O operations and performs one or more disaster remediation operations. After remediation, the computing cluster is restored to a configuration having two nodes. |
