Abstract: Techniques are provided for small file aggregation in a parallel computing system. An exemplary method for storing a plurality of files generated by a plurality of processes in a parallel computing system comprises aggregating the plurality of files into a single aggregated file; and generating metadata for the single aggregated file. The metadata comprises an offset and a length of each of the plurality of files in the single aggregated file. The metadata can be used to unpack one or more of the files from the single aggregated file.

Abstract: Transceivers may be used in track circuits. A transceiver may comprise an H-bridge circuit comprising at least four switches. A control unit in communication with the H-bridge circuit may be constructed and arranged to selectively drive the at least four switches to selectively cause the H-bridge circuit to function as a transmitter or a receiver. A power supply terminal in communication with the H-bridge circuit may be constructed and arranged to connect to a power supply. A track interface terminal in communication with the H-bridge circuit may be constructed and arranged to connect to a track interface cable so that the H-bridge circuit is capable of transmitting signals to and/or receiving signals from the track interface cable.
