Abstract: A call with respect to data for a file from an application program running on a computing device to a block-oriented file access function of an operating system running on the computing device is intercepted. A DAX file access is responsively performed with respect to a memory region of a persistent memory storing the file and an application buffer for the application program within an application memory space to which the memory region has been mapped.

Abstract: In an example, an air filter system includes an air filter and a thermally conductive particulate sensor (TCPS). The TCPS includes a temperature sensor to measure a first temperature of the TCPS at a first time, measure a second temperature of the TCPS at a second time, and provide the measured first temperature and the measured second temperature to a controller. The controller to determine an actual rate of temperature change based on the measured first temperature and the measured second temperature, compare the actual rate of temperature change to a target rate of temperature change, and provide a notification when a difference between the actual rate of temperature change and the target rate of temperature change is greater than an accumulation threshold indicative of a threshold amount of particulate accumulation on the TCPS.

Abstract: A computing system for collecting hardware performance data includes a number of programmable counters associated with a number of units of a computing device. The computing system further includes an assignment module executed by a processor to assign a plurality of interleaving groups of counters based on a user-defined priority list of parameters.

Abstract: In example implementations, a computing system is provided. The computing system includes at least one electronic component, a fan and a filter. The electronic component generates heat that is cooled by an air flow within the computing system that is generated by the fan. The filter is located in a path of the air flow. The filter includes a filter mesh with a strain gauge that is encapsulated and incorporated into the filter mesh to measure an amount that the filter mesh is clogged.

Abstract: An apparatus includes a memory card that includes at least one memory module and an expansion connector to connect with at least one expansion memory card. A lane distributor on the memory card interfaces with a set of bidirectional lanes and provides a base lane set and an expanded lane set of bidirectional lanes to support communications with the memory module and the expansion memory card via the expansion connector.

Abstract: An apparatus includes a pass-through module that includes connector pins to connect with at least one active portion of a motherboard connector and to separately connect with at least one inactive portion of the motherboard connector. A routing function on the pass-through module redirects a set of bidirectional lanes from the connector pins connected to the active portion of the motherboard connector to the connector pins connected to the inactive portion of the motherboard connector to enable a connection of the set of bidirectional lanes to at least one other motherboard resource connected to the inactive portion of the motherboard connector.
