I have no choice, there is only one version of BOINC for 64bit freebsd :(

Why can't you use the Boinc version in Ports?

Urs, sorry for not reporting back but since Jocelyn hasn't been online until now I haven't been able to verify the results. My RAC on that machine has increased during Jocelyn's downtime so some WUs must have been validated. I reported another WU now that got validated immediately and another one is waiting for validation. The FreeBSD version appears to work correctly. Many thanks again for your hard work.

Many thanks for providing the possibility of testing on this platform.
Your CPU is relatively "low end". Do you have any idea of how much speedup you see there ?

The biggest problem, non static fftw library, is currently worked on. Expect a (final) version in the next days. It will be a little bit faster.

I intentionally bought that system for my router/firewall so I went as cheap as possible and it's still overkill for its tasks. Just wanted a 64-bit platform to play with for FreeBSD. CPU was practically for free... :-)

I ran the FreeBSD version form dotsch.de for a while which according to that page is based on the stock code. Execution times were 120 hours then with two simultaneous tasks. As we discussed earlier, the small cache on this CPU hurts performance badly when running two tasks, practically doubling execution time. I therefor run one task at a time now and it takes 44 hours with the optimized app which should be compared to roughly 60 hours then with the stock 5.03 code. So I'd estimate about 30% increase in speed.

New builds are released now for 64bit FreeBSD.

However the Windows version seems to run much faster:

Core2 2.66 GHz faster than my
Xeon 2.83 GHz

Because it allways wants to install tons of X11 libraries and I don't want to use them, I am running FreeBSD as a server only without graphics support.

Astropulse has a binary checkpoint file (ap_state.dat*) which contains the fraction done in a double, so it's not convenient to check that way.

boinccmd --get_results will list all the tasks, including their fraction done.

Or for versions prior to the boinc_task_state.xml change you can open BOINC's client_state.xml file and check the <fraction_done> fields there.

Thanx Josef, that works.

Add WITHOUT_X11=yes to your /etc/make.conf if you want no X on that machine.

Thank you for this AP application:
http://setiathome.berkeley.edu/results.php?hostid=5106981
Result and wu lists are currently unavailable. Which version running on what host ? How much time did it take (compared to another version) ?

When the WU lists were available, from what I remember that was SSE3 64bit WIN APP Core2@2.66GHz vs SSE3 64bit FreeBSD APP Xeon 3360@2.83GHz. But we have to wait until the WU lists on seti HP are available again. That link pointed to both machines - the same workunit.

Was the used FreeBSD AP app r236 or r237 ?  :-\

Urs, I think that was still 236. After I installed 237, I could not compare since the seti was down again... I will letya know. Anyway, the 64bit SSE2 APP works perfectly as well. Let's wait until seti homepage wakes up again  ;)

The wu lists are visible again. r237 is doing nice on your Xeon. What do you think, zvonas, is speed better now ?  :D
