Remarks:
We just mention the Orion 440 here for completeness' sake. Normally Unisys is not concerned with the HPC market but recently Unisys expressed interest in stepping in. As can be seen from the list of characteristics above, the systems are presently offered with a Windows OS, and Linux. The system has a flat crossbar which makes it very similar to those of Bull NovaScale and the NEC TX-7. No further information is available, including performance results.
