Y2K tested machines

This table is an attempt to summarize the results of the Y2K performance tests made on a range of computers owned by the NRAO. The AIPS version was 31DEC00 in all tests. The full details of the test including additional computer configurations and the disk optimization parameters are described elsewhere. The disk optimizations were used in all cases reported here, but the "/tmp" trick was not used on any of the systems. In most of these cases, the binaries were served from another computer via NFS-mounted disk partition.
