Posted 30 Mar 2011 by Vadim Gusev 		I've solved problem, but i don't get one thing:
The solution for problem is to put libboinc.a after libsched.a in g++ command line, as it's done in boinc build system. But changing libs order doesn't change fact of having multiple definitions, it just change order, in which linker will meet them. Then how does library order solve the problem?

Posted 28 Mar 2011 by Vadim Gusev 		Hi, i'm trying to build sample_work_generator.cpp outside of boinc source code tree with my own Makefile.
Here is a list of my code tree:

apps  assimilator  libs  validator  workgen  Makefile  Makefile.incl


"libs" dir contains api, db, lib, sched and tools dirs from BOINC source code tree with compiled libraries.

Here is build log:

g++ sample_work_generator.cpp -pthread -Wall  -I ../libs/api-x86_64 -I ../libs/lib-x86_64  -I ../libs/db-x86_64

Obviously, neither string3.h:86 nor string3.h:107 contain that methods. I'm lost in finding reasons of such behavior. I've posted that problem in boinc_projects mailing list, but got no answers.

Thanks for help in advance.

Posted 6 Mar 2011 by Vadim Gusev 		Suddenly problem got fixed by itself, now i can download jobs, but after completing computation i get this errors:

file_upload_handler.log exists

After changing permissions to rw for all error got fixed, but now i cant download jobs:

Вс. 06 марта 2011 04:38:03	test	Started download of uc_1299268978_2
Вс. 06 марта 2011 04:38:04	test	Temporarily failed download of uc_1299268978_2: HTTP error


I can access job files trough browser, but boinc fails to download them.

Posted 5 Mar 2011 by Vadim Gusev 		Hi there, I'm trying to set up BOINC server. I've followed wiki guide and after compiling and setting up server I've made test job and tried to attach myself to project.

Here is log:

Сб. 05 марта 2011 12:56:27 Fetching configuration file from http://frosty.selfip.org/test/get_project_config.php
Сб. 05 марта 2011 12:56:40 test Master file download succeeded

Сб. 05 марта 2011 12:56:47 Internet access OK - project servers may be temporarily down.


I can navigate through web site and directly access files in /test/download/ directory.

All daemons seems to run fine:
BOINC is ENABLED

DAEMON  pid  status      lockfile disabled  commandline
   1   9006  running     locked   no        feeder -d 3
   2   9008  running     locked   no        transitioner -d 3

   4   9012  running     locked   no        sample_work_generator -d 3
   5   9014  running     locked   no        sample_bitwise_validator -d 3 -app uppercase

   7   9018  running     locked   no        single_job_assimilator -app single_job_i686-pc-linux-gnu
   8   9020  running     locked   no        sample_trivial_validator -app single_job_i686-pc-linux-gnu


frosty.selfip.org is DDNS name, which is resolved correctly (i can access web site, so it's obvious), however i've tried to re-create project with ip as master url instead of domain name - same result.
By default my master url was http://localhost6.localdomain6/test/ but i've grep'ed through all files in project directory and changed it and it's derivatives to correct - same result.

However i get Master file download succeeded message, so it seems like client can communicate with server and it's not a network related problem (i'm connecting to localhost basically, hard to imagine problems here).

Have I missed something while configuring some aspect of server or it's really network issue? Thanks in advance.
5) Message boards : Questions and problems : BOINC requests not needed CPU WUs
Message 36895
Posted 17 Feb 2011 by Vadim Gusev 		My system is:
CPU: Intel Core Quad Q9550
GPU: Nvidia GTX 460
OS: Ubuntu 10.10 x64
BOINC: 6.10.58

My problem is: I'm crunching for Einstein@home and each time BOINC reports completed GPU WU, it requests new WUs for both CPU and GPU.

Чт. 17 февр. 2011 13:37:19	Einstein@Home	Sending scheduler request: To fetch work.
Чт. 17 февр. 2011 13:37:19	Einstein@Home	Reporting 1 completed tasks, requesting new tasks for CPU and GPU
Чт. 17 февр. 2011 13:37:22	Einstein@Home	Scheduler request completed: got 2 new tasks


GPU's WU takes 1 hour to complete, CPU's ones are 4.5 or 15.5 hours, so each hour BOINC requests additional 10 hours of CPU work time in average, even on 4 cores it can't be completed in 1 hour, so in day or two i collect huge amount of CPU WUs, that would take about two weeks to complete.

So the only way to stop incoming WU flood is to suppress WU fetch and GPU computations for a couple of days and crunch only CPU WUs.
