Abstract: A range finding apparatus uses a light-receiving device in which a first pixel having a first sensitivity and a second pixel having a second sensitivity that is lower than the first sensitivity are two-dimensionally arranged. The range finding apparatus measures time periods from a predetermined time until times when light is incident on each of the first pixel and the second pixel, and computes distance information for the first pixel and the second pixel based on the measured time periods. The measurement resolution used to measure the time period for the second pixel is lower than a measurement resolution used to measure the time period for the first pixel.

Abstract: This disclosure provides methods, devices, and systems for memory management. The present implementations more specifically relate to techniques for providing memory services over a CXL fabric. In some aspects, a memory management system may include an orchestration component, one or more host agents, and one or more endpoint controllers. Each host agent manages one or more memory services for a respective host computing device of a CXL system (or subsystem) and each endpoint controller manages one or more memory resources attached to a respective CXL device of the CXL system. The orchestration component coordinates with each host agent and endpoint controller to configure a CXL fabric to support the memory services provided to each host device. The memory management system receives updates associated with the memory services from each host device or CXL device and may dynamically reconfigure the CXL fabric based on the updates.

Abstract: The present invention relates to a process for preparing ethers, particularly unsymmetrical ethers, and preferably ethers suitable for use as base stocks for lubricant compositions. In particular, the process involves the reaction of a branched-chain aldehyde and a branched-chain alcohol to form an enol ether and conversion of the enol ether to a saturated ether by reduction.

Abstract: Techniques are disclosed for dynamic access and instrumentation of model specific registers (MSRs). A virtual machine monitor (VMM) can provide a kernel application program interface (API) that can be utilized to access and instrument an MSR. A method may include receiving, by the VMM, an MSR instrumentation command that identifies an MSR to instrument and causing instrumentation of the MSR identified in the MSR instrumentation command. Instrumentation of the identified MSR can be caused by configuring or manipulating a virtual machine control structure (VMCS) of a guest virtual machine (VM). The MSR instrumentation command may be an MSR instrumentation request command, an MSR remove request command, an MSR value set request command, or an MSR value fetch request command. In some cases, the VMM may be a Type-I hypervisor.

Abstract: Techniques are disclosed for interposing on nondeterministic events during multicore virtual machine (VM) execution to capture information that allows for deterministically recreating the nondeterministic events during execution replay of the VM. A method may include reading, by a virtual processor running within a multicore VM instance, an instruction to execute, and, responsive to a determination that the instruction is a nondeterministic instruction, interposing on the nondeterministic instruction execution so as to allow deterministic execution of the nondeterministic instruction during replay execution of the multicore VM instance. Interposing on the nondeterministic instruction execution may include recording a partial barrier event and/or a full barrier event. The nondeterministic instruction may be a read memory access instruction or a write memory access instruction.
