Here is the CM-2 data for running the stream code. The following switches
were used with CM Fortran compiler:
%cmf stream_d.fcm -o stream
The global optimizer was disabled due to the way the code was written, the
global optimizer will remove all of this code out of the loop since it is
loop invarient and then the timings will be totally bogus.
The software used for this was the following:
1. CM Fortran Compiler Release 1.1
2. CMost Release 6.1 Beta II
The machine used was CM2 64K, CM2 32K and CM2 16K all running at 7Mhz.
