摘要： A method and an apparatus for selecting a node where a shared memory is located in a multi-node computing system are provided, improving the total access performance of the multi-node computing system. The method comprises: acquiring parameters for determining a sum of memory affinity weight values between each of the CPUs and a memory on a random one of nodes; calculating the sum of the memory affinity weight values between each of the CPUs and the memory on the random one of the nodes according to the parameters; and selecting the node with the calculated minimal sum of the memory affinity weight values as the node where the shared memory for each of the CPUs is located.

摘要： A container, which is adapted to receive an elongated saw blade of a reciprocating saw, comprises a separate body with an engaging portion. The engaging portion can be engaged with a cover to form a chamber. Thus, the saw blade may be received in the chamber. The container may be fit in a storage case which has two engageable parts, at least one of which comprises a set of receiving slots for holding the containers.

摘要： A system and method for measuring and neutralizing the electrical charge at the interface of a magnetic head and a magnetic storage medium, such as a disk, is disclosed. A surface treatment material is applied to the magnetic head. The surface treatment material matches the medium surface material on the surface of the magnetic storage medium. The surface treatment material on the magnetic read/write head may be a fluorinated carbon, such as a Fomblin Z-derivative, perfluoro alkyl trichlorosilane, a FC-722, or a fluorinated polymer. The surface treatment material can be applied to the magnetic head by a vapor deposition process or by a liquid immersion process. The charge on the head-disk interface can be measured by applying varying external charges to the head while reading a signal previously written to the disk.
