Techniques are provided for journal replay optimization. A distributed storage architecture can implement a journal within memory for logging write operations into log records.

The time to complete the replay of the write operations is significantly reduced by caching metadata (e.g., indirect blocks, checksums, buftree identifiers, file block numbers, and consistency point counts) directly into log records. Replay can quickly access this metadata for replaying the write operations because the metadata does not need to be retrieved from the higher latency disk storage into memory. |

Generational physical address proxies
Each PIPT L2 cache entry is uniquely identified by a set index and a way and holds a generational identifier (GENID). The L2 detects a miss of a physical memory line address (PMLA). An L2 set index is obtained from the PMLA. The L2 picks a way for replacement, increments the GENID held in the entry in the picked way of the selected set, and forms a physical address proxy (PAP) for the PMLA with the obtained set index and the picked way. The PAP uniquely identifies the picked L2 entry. The L2 forms a generational PAP (GPAP) for the PMLA with the PAP and the incremented GENID. A load/store unit makes available the GPAP as a proxy of the PMLA for comparisons with GPAPs of other PMLAs, rather than making comparisons of the PMLA itself with the other PMLAs, to determine whether the PMLA matches the other PMLAs. |

Register reading method and apparatus, device, and medium
A register reading method and apparatus, a device and a medium. After a server is crashed, a CPU-register collecting request is triggered. Different types of CPUs correspond to different types and quantities of registers that require data collection. Therefore, by firstly determining the register required to be read corresponding to the CPU type, and determining the reading mode of the register, the disadvantage that the reading mode that may merely use a single instruction may not satisfy the demand on field crashing analysis is prevented. Subsequently, by using a PECI bus, the register data of a plurality of registers are read. By collecting the registers of the CPU directly by using the PECI bus, the problem that the performance excessively relies on the stability of the ME due to the intermediate transfer via the ME is prevented, which greatly increases the reading success rate of the registers. |

Optimized sampling of resource content data for session recording under communication constraints by independently capturing agents
A technology for the optimized capturing of resource file content for resources referred in recorded user interaction sequences is disclosed.

Methods for ultraviolet excitation microscopy of biological surfaces
Microscopy with Ultraviolet Surface Excitation (MUSE) for use in the classroom to enhance life sciences education and curricula, or for other applications, including without limtiation the operating room, other medical environments, research environments, and low resource environments.

System and method for aligning HVAC consumption with renewable power production with the aid of a digital computer
HVAC load can be shifted to change indoor temperature. A time series change in HVAC load data is used as input modified scenario values that represent an HVAC load shape. The HVAC load shape is selected to meet desired energy savings goals, such as reducing or flattening peak energy consumption load to reduce demand charges, moving HVAC consumption to take advantage of lower utility rates, or moving HVAC consumption to match PV production. Time series change in indoor temperature data can be calculated using only inputs of time series change in the time series HVAC load data combined with thermal mass, thermal conductivity, and HVAC efficiency. The approach is applicable for both winter and summer and can be applied when the building has an on-site renewable power system. |
