Dockimbel 22-Feb-2012 [5288] | Possible. |
Kaj 22-Feb-2012 [5289x7] | Performancewise, 100 or 1000 seem most likely |
1000 or 10'000 really | |
It's 1000: | |

But stupid Windows measures wall-clock time instead of processor time | |
That explains why your measurement is pretty much the same as on my old CPU | |
I'm working on new benchmarks that you'll like :-) | |
PeterWood 22-Feb-2012 [5296] | Kaj - you should also be aware of this note iin the Libc docs: — Macro: int CLOCKS_PER_SEC The value of this macro is the number of clock ticks per second measured by the clock function. POSIX requires that this value be one million independent of the actual resolution. |
Kaj 22-Feb-2012 [5297x2] | Yes, that's already in the notes in my binding. See above (XSI-conformant systems) |
I've just fixed the clocks-per-second value on Windows | |
Dockimbel 22-Feb-2012 [5299] | New branch started: `libc-init` First commit contains proper init code for libc on Linux. It works ok, but additional testing needs to be done. Also support for other platforms needs to be added. https://github.com/dockimbel/Red/tree/libc-init |
Pekr 22-Feb-2012 [5300] | Any few words about what libc-init branch is about? |
Dockimbel 22-Feb-2012 [5301x2] | Trust me, you don't want to know. ;-) |
The main point is being able to properly call this "beast" from Red/System: http://www.msbit.com:82/LSB/booksets/LSB-Core-generic/LSB-Core-generic/baselib---libc-start-main-.html | |
Kaj 23-Feb-2012 [5303x2] | My Fibonacci benchmark results have scrolled way out of sight in the Other Languages group, so I'll repeat them here: |
Syllable Server, AMD Athlon XP 1800+ (256 KB L2 cache) CPU Time Relative C (GCC -O3) .14 1 C (GCC 4.4.3 i686) .24 2 Red/System .26 2 Ruby 1.8.7.248 (i486) 29 200 Boron (i486) 31 200 REBOL 3 2.100.111.4.4 41 300 ORCA (i486) 50 350 REBOL 2 2.7.7 55 400 World 10:27:00 * > 260,000 *: Aborted after this time. | |
Pekr 23-Feb-2012 [5305] | How is that R/S jumped so high? A different test this time? |
Kaj 23-Feb-2012 [5306x2] | Yes, that's what we discussed there. This one doesn't test floating point, but integer performance and function calling |
As Doc explained, floating point performance is currently a bit hampered | |
Dockimbel 23-Feb-2012 [5308] | Nice! :) |
Pekr 23-Feb-2012 [5309] | Raspberry Pi got Fedora Remix yesterday. Can't wait for the release, and getting Red running there :-) |
Gerard 24-Mar-2012 [5310] | Hi Doc, I know you'Re working on the lexer and I asked myself if you would use some toolset like the Coco/R compiler generator to help you for the next phase (parsing)? It seems it has already been converted for many other languages. Here are the links for the user manual and the other resources for using it if necessary ... http://www.ssw.uni-linz.ac.at/Coco/Doc/UserManual.pdf http://www.scifac.ru.ac.za/coco/ |
Gregg 24-Mar-2012 [5311] | You may want to post on the REBOL4 world. Most conversation has moved there at this point. |
Henrik 25-Mar-2012 [5312:last] | Yes, you should be invited. |
