New Bench ? :-)



#9

5 RADIANS
10 A=1
20 FOR I=1 TO 2499
30 A=TAN(ATN(EXP(LOG(SQR(A*A)))))+1
40 NEXT I
50 PRINT A

Hi gileno,

have you missed this question ? ;-)

A good idea. After having a benchmark for a non numerical problem, I also thought about a simple but convincing numerical benchmark. I think the basic problem is to find an usable program for testing. Probably a mix of simple float calculations and some mathematical functions are not bad.

An example for a simple float test:

0->A
LBL0
A*A/A+A-A+1->A
GOTO0

This is a well-known benchmark usually known as the "Savage" benchmark. I have run it on several HP models in the past, and I will post results if I can find them in my old (deeply buried!) papers. I would definitely enjoy seeing results from other machines and look forward to many submissions!

Thanks,
John

Yes, this has been discussed here already:

The original benchmark program can be found here (Page 12, Column 1):

Well, 50G w/HPGCC @12MHz takes .52s and returns 2500

Not sure exactly how many digits are being used internally. Anyone know?

With the SDK compiler, the FX-9860GSD takes 0.42 seconds.

Why 12 MHz on the HP-50G? Is there another reason except for less power consumption?


#15

Its just the default speed when compiling. You have to add in a sys_slowOff(); at the beginning, or modify a loader file to not mess with system speed.

Keep in mind that there is always a .05-.06s penalty to START the program in saturn land. That is how long an empty program takes to run.

#16

A couple of timings:

HP-71B: 344.82s

HP-49g+: 63.48s (using BINTs for loop variables)

Both return 2499.99948647 like all Saturn-based HP's.
