Remarks:
We just mention the Aries 420 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.
