In terms I understand, what's a J90, and
what's it worth?
A used, operational J90 is worth anywhere from ~$8K-35K depending on
configuration.
Here's some quick info:
Type: PVP (parallel vector processor)
CPUs: 4 min, 32 max
CPU architecture: YMP family binary compatible
Memory: 4GB max
Disk: unbelievably huge quantities possible
Performance: 200MFLOPS sustained per CPU
Word width: 64 bits
FP capabilities: 64 bits single-precision, goes up from there
Vector element depth: 64 elements
Cooling: air
Power: 220V split-phase, about 3-4KW depending on config
OS: Unicos (SystemV variant)
Languages: C, C++, Fortran77, Fortran90, others
I have a relatively large J90 here. Pics of it can be seen at
http://www.neurotica.com/cray/mine. I absolutely love this machine.
It is, for lack of better descriptive terms, UNCOMFORTABLY fast when
crunching numbers.
