摘要： To achieve optimal thermal contact between opposing surfaces, it is necessary to align such surfaces so that maximum contact is achieved. In a semiconductor package, it is necessary to align the surface of a semiconductor integrated circuit (IC) and a heat sink surface, where the heat sink contains a nano-composite wire structure. By using a self-aligned structure that forces the alignment of the IC surface and the heat sink, maximum thermal contact between the two surfaces is achieved. The self-alignment of a pressure measurement device for same is also disclosed.

摘要： An online tree quota check tool computes quota usage of files in a directory tree while the structure of the directory tree keeps changing due to concurrent write access by other applications and clients. The quota check tool computes the quota usage without interfering with the ongoing file access operations that change the directory content and quota usage. A quota check database keeps track of which files have been checked and which have not, so that each file is checked and its quota usage is accumulated once and only once while directories are moved and directory scans are restarted as a result of the changing directory content. File system operations are modified to synchronize with the online tree quota check. The quota check tool can be single threaded or multi-threaded. A multi-threaded tool dispatches idle directory iteration threads to scan subdirectories in the directory tree.

摘要： A technique performs a write operation. The technique involves receiving, after a snapshot of a file system is taken, a write instruction to write new data to a particular portion of the file system. The technique further involves includes reading, in response to the write instruction, metadata to determine whether the new data is a first update of the particular portion since the snapshot was taken. The metadata identifies portions of the file system which have changed since the snapshot was taken. The technique further involves, when the new data is a first update of the particular portion since the snapshot was taken, copying the original data from cache memory (i.e., from the file system buffer cache) to snapshot storage (i.e., to a dedicated save area) and, after the original data is copied, updating the original data in the cache memory with the new data.
