摘要： A deque of a local process in a memory work-stealing implementation may use one or more data structures to perform work. If the local process attempts to add a new value to its deque's circular array when the data structure is full (i.e., an overflow condition occurs), the contents of the data structure are copied to a larger allocated circular array (e.g., a circular array of greater size than the original circular array). The entries in the original, smaller-sized circular array are copied to positions in the now-active, larger-sized circular array, and the system is configured to work with the newly activated circular array. By this technique, the local process is thus provided with space to add the new value.

摘要： The programming method includes the following steps: sequentially receiving a plurality of data words; temporarily storing each data word after its reception; and simultaneously writing in parallel the plurality of stored data words in a memory array. After reception and temporary storage of each data word, the memory increments an address counter and sends a “ready” signal. Upon reception of each new data word, the memory verifies whether the address associated thereto is in the same sector as the initial data word and whether n data words have already been stored. If the sector is different, blind-programming step is terminated and the verifying is carried out; if the sector is the same but n data words have already been stored temporarily, the memory writes the temporarily stored words in the memory array, updates the address counter, and then sends the “ready” signal.

摘要： A software refreshed memory device comprises a plurality of memory cells that must be periodically refreshed to avoid losing data. Preferably, the memory cells can avoid losing data even though the time interval between successive memory refresh operations is relatively long, as compared to the time interval between successive memory refresh operations in a conventional volatile memory device, such as a DRAM. A processor can perform periodic memory refresh operations by executing a set of memory refresh instructions implemented in software, rather than in hardware. Accordingly, the memory device can advantageously be simplified, because the need for memory refresh circuitry and for a unique refresh control signal are advantageously eliminated. Moreover, the processor executing the memory refresh instructions can typically perform more sophisticated algorithms, as compared to memory refresh circuitry implemented in hardware, for determining when to perform a memory refresh operation. For example, the processor can determine whether each individual memory cell needs to be refreshed, thereby advantageously avoiding performing unnecessary refresh operations on memory cells that do not need to be refreshed.

摘要： Information regarding volume mount points hosted by a logical volume are stored on the physical device underlying the logical volume so that the relationships between the host logical volume and target logical volumes mounted on the volume mount points can be reconstituted when the system containing the logical volumes is rebooted, when the underlying physical devices are moved with the system, and when the logical volumes are transported to a different system. A data structure stored on the physical device contains the directory name of the volume mount point and the unique identifier and a globally unique mount name of the target logical volume mounted at the volume mount point. When the target logical volume is present in the system, symbolic links are created to relate the volume mount point name to a device name for the target logical volume so that pathnames containing the directory junction name are resolved correctly. If the target volume is not present in the system, the corresponding symbolic link does not exist, so an incorrect logical volume cannot be mounted onto a volume mount point. Furthermore, because the logical volumes contain the directory junction information, the namespace representing the logical volumes is self-describing so that neither user knowledge nor intervention is required to reconstitute the namespace.
摘要翻译：有关由逻辑卷托管的卷安装点的信息存储在逻辑卷底层的物理设备上，以便在包含逻辑卷的系统为包含逻辑卷的系统时，主机逻辑卷与安装在卷安装点上的目标逻辑卷之间的关系可以重新构建当底层物理设备与系统一起移动时，以及何时将逻辑卷传输到其他系统时重新启动。存储在物理设备上的数据结构包含卷安装点的目录名称和唯一标识符以及安装在卷安装点的目标逻辑卷的全局唯一安装名称。当系统中存在目标逻辑卷时，会创建符号链接，以将卷安装点名称与目标逻辑卷的设备名称相关联，以便正确解析包含目录结名的路径名。如果系统中不存在目标卷，则相应的符号链接不存在，因此不正确的逻辑卷无法挂载到卷安装点上。此外，由于逻辑卷包含目录结点信息，表示逻辑卷的命名空间是自描述的，因此不需要用户知识和干预来重构命名空间。
