1) Message boards : News : Deprecation of Linux 32bit (Message 63941)
Posted 19 Sep 2015 by Alessandro Freda
May I suggest a -static executable for linux 32 ?
IMHO should be the most reliable solution for all linux executables, because of the babel of linux distributions.

Regards,
Ale

Solved! :)

I've deleted these files from BOINC data dir:

sched_reply_milkyway.cs.rpi.edu_milkyway.xml
sched_request_milkyway.cs.rpi.edu_milkyway.xml
statistics_milkyway.cs.rpi.edu_milkyway.xml


restart BOINC => 24 WU downloaded immediately.

Notice that before failed a project reset and even a detach-attach.

Since the server change when using the app_info.xml ATI 0.20b version you may need to set MilkyWay preferences "Use CPU (enforced by 6.10+ clients)" to yes and "Use ATI GPU if present (enforced by 6.10+ clients)" to no.


This do not seems works.
Logs before mod:
13/01/2010 16:05:35 Milkyway@home Sending scheduler request: To fetch work.

13/01/2010 16:05:40 Milkyway@home Message from server: No work sent

Log after the mod:

13/01/2010 16:05:55 Milkyway@home Scheduler request completed

Seems that the client stop to request work.
BTW dont like waste CPU time on this project that can use the (more powerful) GPUs.

8) Message boards : Number crunching : cache = 0 WU (Message 35570)
Posted 12 Jan 2010 by Alessandro Freda
Yesterday after weeks of normal behavior (cache = 24 WU) without any change my client side, the server start to send only 1 WU and with a waiting time of about 1 min. between result upload and WU download. This cause continue start and stop of the Collatz that cause also a slow down on its WU (double the GPU time per WU).

So I've reset the project leaving the optimized .20b 64bit intel application (running on a 4770), and try the standard application, but at this point no more WU.

I've detached the project waiting for a solution.
Any idea ?

Why detach?

I've attach again without behaviour change.

Have you set your preferences to use GPU?

Yes. There was no change in the preferences when the server start to send the message "No work sent". Now I've try some mods without success. Is it possible continue to use the app_info.xml to send cmdline to the old 0.20b release ?

Sorry, my complete log was:

This is the BOINC error log that hopefully can help troubleshooting.

This is Solaris 9 using the BOINC 5.10.17 client

1/27/2008 01:21:33|Milkyway@home|Starting gs_163_1201401068_278582_0

I've found the same problem downgrading a sunfirev240 from Solaris 10 to 9.
I've backuped in a tar file the working boinc (5.10.17) user, and as usual move to the new env.

Without the libm.so.2 present the task continue to restart:

Project Date Message
Milkyway@home 23/04/2008 23.20.39 Restarting task gs_571_1208988172_92822_0 using astronomy version 121

after coping the libm.so.2 from a Solaris 10 server, (ldd => ok) I see a WUs waste with continue computation error.

Have you found the solution ?

Regards,

Alessandro
