Hello,
a long time ago somebody asked for TIME_TEST on an SGI Octane.
Our Octane:
1 175 MHZ IP30 Processor
CPU: MIPS R10000 Processor Chip Revision: 2.7
FPU: MIPS R10010 Floating Point Chip Revision: 0.0
Main memory size: 128 Mbytes
Graphics board: SI
Since yesterday IDL 5.0.3 is running on this machine. We get:
