A computer data signal embodied in a propagation medium is provided. The signal enables a variable number of data transfers and includes an initial connection source code segment and a data transfer source code segment. The initial connection source code segment establishes a connection between at least two devices via predetermined listening ports, with at least one predetermined listening port residing within each device. The initial connection source code segment also dynamically assigns a first data port within a first device, and transmits the address of the first data port to a remaining device via the predetermined listening ports. The data transfer source code segment is for each of the variable number of data transfer operations. The data transfer source code segment dynamically assigns a corresponding second data port within the remaining device and transfers data between the connected devices via the data ports so that the data is substantially simultaneously transferred between a variable number of devices via the data ports. Each pair of first and second data ports is established in response to each listening port connection.

An adaptive replacement cache policy dynamically maintains two lists of pages, a recency list and a frequency list, in addition to a cache directory. The policy keeps these two lists to roughly the same size, the cache size c. Together, the two lists remember twice the number of pages that would fit in the cache. At any time, the policy selects a variable number of the most recent pages to exclude from the two lists. The policy adaptively decides in response to an evolving workload how many top pages from each list to maintain in the cache at any given time. It achieves such online, on-the-fly adaptation by using a learning rule that allows the policy to track a workload quickly and effectively. This allows the policy to balance between recency and frequency in an online and self-tuning fashion, in response to evolving and possibly changing access patterns. The policy is also scan-resistant. It allows one-time-only sequential read requests to pass through the cache without flushing pages that have temporal locality. The policy is extremely simple to implement and requires only constant-time overhead per request. The policy has negligible space overhead.

The present invention is directed to a method, system and program for exporting-importing the content of input cells from a source scalable template instance in a source multi-dimensional spreadsheet to a destination scalable template instance in a destination multi-dimensional spreadsheet; a multi-dimensional spreadsheet comprising a plurality of cells identified by a cell address along each dimension; a scalable template instance comprising a variable number of contiguous elements of same size ordered and aligned along a given spreadsheet dimension and structured according to information defined in an associated scalable template; an element being defined as a range of cells; a range of cells comprising one or a plurality of cells; said scalable template comprising an element profile; an element profile defining a cell content and a cell destination for each cell within each element; said cell destination specifying whether the cell is an input cell for receiving an entry or an output cell for producing a result. The method comprises the steps of: detecting a command for exporting-importing input cells from a source scalable template instance in a source spreadsheet to a destination scalable template instance in a destination spreadsheet; identifying the source scalable template associated with the source scalable template instance; identifying cells, if there are any, defined as input cells in the element profile of the source scalable template; identifying the destination scalable template associated with the destination scalable template instance; Identifying cells, if there are any, defined as input cells in the element profile of the destination scalable template; copying cell per cell, the content of each input cell of the source scalable 36 template instance in each input cell of the destination scalable template instance.
