    摘要： An apparatus for data transfer includes a first node connected to a bus to communicate bidirectionally, and second nodes connected in series to the bus. Each second node lacks an internal clock and has fixed pads including a power, a ground, and signal pads to transfer a data frame, return data pads for a return signal, select pads for a selection signal and clock pads for a clock signal. Each second node is indexed by a hop count in the frame that is incremented each time the frame is transferred in topological order. Each second node is selectable using a mode defined by a combination of the hop count, a mask field and an address field in the frame. The signal pads are used for frame transfer in a selected mode controlled by a combination of the selection, clock and return signals.

    摘要： A method for managing main memory including DRAM and NVRAM in a computer depending on the operation state of the computer is provided. The method includes: (a) upon start of the computer, loading a program and the like into the DRAM, and loading predetermined read-only data and the like into the NVRAM; (b) in a state transition from a normal operation to a suspend state, moving data in the DRAM to the NVRAM; (c) in a state transition from the suspend state to the normal operation, reading data from the NVRAM for program execution; (d) in the case where a data write to the NVRAM occurs, stopping the data write, and moving data in a data area of the NVRAM subjected to the data write, to the DRAM; and (e) performing the data write to the DRAM to which the data has been moved.

    摘要： An improved method for identifying trace data relating to a particular virtual machine from trace data acquired by a tracer node. The method is executed in a computing environment including at least one processing node and a tracer node for acquiring a trace of access to a memory apparatus thereof. The method includes the steps of: starting recording of trace data containing information of the trace of the access to the memory apparatus of the tracer node; storing, in response to migration of the particular virtual machine from a given processing node to the tracer node, information identifying a physical address of the memory apparatus of the tracer node, the physical address being assigned to the particular virtual machine; and identifying the trace data relating to the particular virtual machine from the trace data, using the assigned physical address of the memory apparatus of the tracer node.
