An insulated concrete wall structure having a concrete wall with opposing wall surfaces. A combination of the invention comprises a surface, which comprises a plurality of test regions, at least two of which, and in a preferred embodiment, at least twenty of which, are substantially identical, wherein each of the test regions comprises an array of generic anchor molecules. In response to receiving an indication that said plurality of instances of data is being accessed as a row of data, a first address translation table is accessed which describes the same row address in each of said plurality of memory modules wherein an instance of data is stored. The initiate flow control mechanism manages these shared buffers to reserve bandwidth for complete transactions when extensive global initiate traffic to one or more nodes of the system may create a bottleneck in the switch fabric. The length dimension L is preferably aligned within 30\xb0 parallel to the grain, and more preferably within 10\xb0 parallel to the grain.
