Power Developer :: libfreevec 1.0.3 & benchsuite 1.0.2 released!

After long hours of testing and debugging, CODEX releases libfreevec 1.0.3, get it here!

For benchmarks, check http://www.freevec.org/functions

Though developed for libfreevec, benchsuite is easily adapted to work with any function.
(perhaps I will include a small howto if there is demand).

Anyway, enjoy!

Hi. Unfortunately I can't download this package :(Web-site www.codex.gr can not be found from my computer (but Google has cached pages from it) and also I can't find download section on freevec.org ...

Please advice where can I get these sources? Thank you!

P.S. It looks like codex.gr was expired yesterday:

Hi,

Yes there was a problem with my registrar, though I had paid for the domain's renewal, they didn't actually do it, so the domain expired. It should be working ok now, so please try again in the same URL :)

Thanks! Link is working now :)

Cool, I would really really appreciate any feedback on the library :)

Another question: Should random.dat consist of random data? On my system I have random.dat with zeros after running prepare_data.sh...

LOL,

I should have used /dev/random instead of /dev/zero in prepare_data.sh!!

Sorry about that, fixed in svn :)

Could you please tell me SVN path to checkout this source code?
On svn://svn.codex.gr/trunk/benchsuite it's still /dev/zero

P.S. With random data (that was generated by simple C-program) test-strncpy is failed...

Same repo, could you try again now? I removed the shell script (was taking ages to populate ~6MB of random data) and replaced it with a C file that is producing real random data that includes NO zero bytes (which were causing the test-strncpy test program to fail for obvious reasons, it was mistakingly copying data up to the wrong position). Now it reports success.

Also, I've added some -work in progress- test programs for some altivec math replacement functions that I'm working on (sinf, cosf, etc, replacements). These are still not committed in the libfreevec repo so the test will fail :-/

Thanks for the feedback, it's really appreciated :)

Also I noticed that sometimes you use random() that is not ANSI standard instead of rand() and INT_MAX and CHAR_MAX instead of RAND_MAX.

And why in strcmp reported alighnments are -1 and 0?

And here is the software that I used to create all the benchmarks. http://www.codex.gr/article/benchsuite_102_released Every function has its own testing/benchmarking software and you can configure the number of threads (yes, you can actually run the same test in parallel and measure the actual overhead), the number of loops, min/max sizes, test aligned/unaligned access, same/random data (random data access is much more realistic than an artificial benchmark clearing the cache each time) and other features. The benchmark data are written on a SQLite database, so you can work on them afterwards any way you like! Though developed for libfreevec, benchsuite is easily adapted to work with any function. (perhaps I will include a small howto if there is demand). Anyway, enjoy!
