Hi John,
this is what I get on a SGI Challenge ( 1 cpu ).
zarah2:~/benchmarks-> uname -a 18:25
IRIX zarah2 5.1.1.1 10011612 IP19 mips
zarah2:~/benchmarks-> hinv 18:25
18 150 MHZ IP19 Processors
CPU: MIPS R4400 Processor Chip Revision: 5.0
FPU: MIPS R4010 Floating Point Chip Revision: 0.0
Data cache size: 16 Kbytes
Instruction cache size: 16 Kbytes
Secondary unified instruction/data cache size: 1 Mbyte
Main memory size: 512 Mbytes, 4-way interleaved
I/O board, Ebus slot 15: IO4 revision 1
Integral IO4 serial ports: 4
Integral Ethernet controller: et0, Ebus slot 15
Integral SCSI controller 1: Version WD33C95A
Disk drive: unit 8 on SCSI controller 1
Disk drive: unit 4 on SCSI controller 1
Disk drive: unit 3 on SCSI controller 1
Disk drive: unit 2 on SCSI controller 1
Disk drive: unit 1 on SCSI controller 1
Integral SCSI controller 0: Version WD33C95A

Compiler options:
f77 -ddopt -mips2 -O4 -non_shared -o stream stream.f
zarah2:~/benchmarks-> ./stream 18:27
--------------------------------------
Single precision appears to have 7 digits of accuracy
Assuming 4 bytes per default REAL word
--------------------------------------
Timing calibration ; time = 42.00000 hundredths of a second
Increase the size of the arrays if this is <30
and your clock precision is =<1/100 second
---------------------------------------------------
Function Rate (MB/s) RMS time Min time Max time
Assignment: 66.6667 0.1271 0.1200 0.1300
Scaling : 66.6667 0.1291 0.1200 0.1400
Summing : 66.6667 0.1921 0.1800 0.2000
SAXPYing : 63.1579 0.1941 0.1900 0.2000
And this is for cstream:
Compiler options:
cc -sopt -O4 -mips2 -non_shared -o cstream cstream.c -lfastm
zarah2:~/benchmarks-> ./cstream 18:31
Timing calibration ; time = 980.00 usec.
Increase the size of the arrays if this is < 300
and your clock precision is =< 1/100 second.
---------------------------------------------------
Function Rate (MB/s) RMS time Min time Max time
Assignment: 69.837 245.051 240.000 250.000
Scaling : 69.837 250.080 240.000 260.000
Summing : 69.837 368.076 360.000 380.000
SAXPYing : 71.832 361.040 350.000 370.000
Best regards,
