Code: Pascal  [Select][+][-]
  1.   procedure AddArrays2(const arr0:aos;arr1:aos;arr2:aos;arr3:aos);
Is even faster.

Shorter, you mean? Here it is not faster.
Ah, on another PC it is indeed faster, but not on my laptop. Strange.

Hello BobDog.

Many thanks for your code.
But here, on Linux Debian 11 64 bit, with a intel i5 and 16 megas RAM, compiled with fpc 3.2.2,  t2:=gettickcount64-t; = always 0, for both methods.

So it is difficult to estimate if one is faster than the other.

It is strange because it I add a sleep(1);,  t2:=gettickcount64-t; = 1, as wanted.
Is a kind of "application.processmessages" needed to get the right gettickcount64 ? (or my machine is maybe too fast and the result is < than 1 tickcount).

Here my result:

Code: Bash  [Select][+][-]
  1. fred@fredvs ~> ./testarray
Quote
Please wait a second or so . . .
.
.. // 10 x the code that follow from 1 to 10

0
0 global 0 0 0 0 0
0 params 0 0   10 of 10

Totals
Time with globals 0
Time with params  0
Press return to end

Hello.

@ BobDog, bytebites, Thaddy: it seems that you have more luck than me with the BobDog-code.

I always get 0 as result.

But it could be interesting to see the result with a multiplication too, with something like this in code, and do the same for parameter method:
( I want to test it but on my machine tickcount duration is also = 0 )

Code: Pascal  [Select][+][-]
  1. var
  2. ratio : single = 0.123;
  3. ratio1 : single = 0.345;
  4. ratio2 : single = 0.567;
  5. ratio3 : single = 0.890;
  6.  
  7. procedure AddArrays() ; // and multiply
  8. var
  9.   i : integer;
  10.   begin
  11.   // all arrays have the same size
  12.     for i := 0 to length(arr0) -1 do
  13.     begin
  14.     arr0[i]:=0;
  15.     arr0[i] := ratio * ( (ratio1 * arr1[i]) + (ratio2 * arr2[i]) + (ratio3 * arr3[i]) ); // here ratio multiply
  16.     end;
  17.   end;

This to see if parameter method has impact too on multiply.

Hello.

OK, I found the problem.
Here on Linux it failed because in procedure AddArrays() , i must be int64 otherwise range check error

Code: Pascal  [Select][+][-]
  1. procedure AddArrays() ; // and multiply
  2. var
  3.   i : int64; // change this
  4.  
  5.   procedure AddArrays2(var arr0:aos;arr1:aos;arr2:aos;arr3:aos);
  6. var
  7.   i : int64; // change this

Now there is a tickcount duration.
Time to investigate, write you later.

With this code lightly changed from BobDog-code :

  112.      writeln('Press return to end');
  113.      readln;
  114.     end.    
  115.      

I get this as result on Linux 64 and fpc 3.2.2, i5, 16 G ram.
You may see that the difference is very light (here params const is faster).

It is to make work the machine.  ;)

In my previous post edited, added in code the method with parameters but without var/const.
And this one wins with -03 on my system.

Strange all that differences (but not very impressive).

By the way, your results are much faster than mine, my machine is a laptop Thinkpad X390.

I get this as result on Linux 64 and fpc 3.2.2, i5, 16 G ram.
You may see that the difference is very light (here params const is faster).

[EDITED]
Same test but compiled with -O3 optimization:  (here params nil is faster).

Hello.

About speed with float calculation.

It would be interesting to see also the result using fpc-LLVM.

There is the wiki https://wiki.lazarus.freepascal.org/LLVM that explains how to build the compiler.
But does it exist a fpc-LLVM release ( with binaries for Linux 64 bit for example ) ?
( I am terribly lazy and without free-time those days. )

Even more, if somebody has fpc-LLVM binary working, could he be so kind to test the demo program to see if there is a difference in result vs the "classical" fpc version ?

Many thanks.

@ Mischi: thanks for testing.

Did you use the "classical" fpc or the one compiled for LLVM ?
If it was with the "fpc-LLVM", can you compare your result with the "classical" fpc ?

Thanks.

Classic. I tried to build fpc-LLVM with 3.2.2, but i did not manage. So, giving up for the moment.
