Brute force addition speed test - various models - results?
Message #1 Posted by Gene Wright on 28 May 2010, 10:26 a.m.

Xerxes has done a great job with the complex speed test N-queens problem for various calculators as detailed in his Benchmark article (and Hi Xerxes...I've found your posts on a Casio board as well).

I'd like to get a list of speeds for a much simpler program, that ONLY goes after one thing: addition.

LBL 01
+
GTO 01
where the stack contains 0 1 1 1 on 4 level machines. In other words, start with 0 and do repeated additions of 1 for 60 seconds. What is the result?

I know Xerxes' test checks many other things, but how do they stack up with this?

Please post:

The machine used
Your count after 60 seconds
Your program code.

I'll start:

Machine: HP 12c+
Count: 78640
Code: + GTO 01

Machine: HP 12c platinum
Count: 1386
Code: + GTO 001

Machine: HP 30b
Count: 72517
Code: LBL 00 + GOTO 00
(as first program in memory)

Machine: HP 67
Count: 226
Code: LBL 1 + GTO 1

Machine: HP 41c
Count: 1063
Code: LBL 01 + GTO 01

Anyone testing on a 48gII/49g+/50g, remember to be in approximate mode. Otherwise you may be doing exact symbolic adding.

I used the <<1 + A>> stored in A method to as closely as possible emulate Gene's RPN routine. It did not seem to make much difference in Exact or Approximate. I also stick to User RPL without speed enhancement as I think that's what most users use.

Edit: of course in hindsight the <<1 + A>> is not fair as it exits and re-enters the program continously, so a loop is indeed better.

Guilty as charged. Interesting that there was a little difference between adding 1 and 1. but both were still in exact mode (or just could have been my variation in pressing the cancel key...

Raymund, I imagine there is some overhead in setting (and especially checking) a timer. It would be interesting to not do the timer and just manually interrupt it at 60 seconds and see what the count is.

Hi Don,

about 10 times hand stopped: Average := 4295
about 10 times hand stopped: Average := 4303 (2 minutes / 2)
Program:
10 A=A+1 @ GOTO 10
A=0 [RUN]

Variant (all statements in direct mode):
about 10 times hand stopped: Average := 3136
about 10 times hand stopped: Average := 3131 (2 minutes / 2)
Immediate code:
A=0
FOR T=1 TO 999999 @ A=A+1 @ NEXT T

I think the timer is more accurate. According to the IDS, it generates an interrupt.
It is not a polling timer!

BR
Ray
PS, See also this approach to determine the best guess.
Could be changed for the basic variant of course ....

The first three used this program:

The thing I find interesting here is that the integer version of the code is substantially slower than the floating point equivalent. That really doesn't make a lot of sense but it does indicate how much effort was likely put into the floating point implementation.
