Hi, Some volunteers are getting messages similar to these:
2010-08-02 10:04:11 a...@home Message from server: Result iq64CT6a_100720c_2_4_0 is no longer usable 2010-08-02 10:04:11 a...@home Message from server: Result iq64CT6a_100720c_2_21_0 is no longer usable 2010-08-02 10:04:12 a...@home Computation for task iq64CT6a_100720c_2_4_0 finished I checked and we don't seem to have canceled any work. On the sever we observe the following: mysql> select claimed_credit, userid, server_state from result where name regexp "iq64CT6a_100720c_2_4"; +----------------+--------+--------------+ | claimed_credit | userid | server_state | +----------------+--------+--------------+ | 15001 | 18471 | 5 | | 0 | 46129 | 4 | | 0 | 41045 | 4 | | 15001 | 46793 | 5 | | 0 | 0 | 2 | +----------------+--------+--------------+ 5 rows in set (0.30 sec) mysql> select granted_credit, userid, server_state from result where name regexp "iq64CT6a_100720c_2_4"; +----------------+--------+--------------+ | granted_credit | userid | server_state | +----------------+--------+--------------+ | 0 | 18471 | 5 | | 0 | 46129 | 4 | | 0 | 41045 | 4 | | 0 | 46793 | 5 | | 0 | 0 | 2 | +----------------+--------+--------------+ 5 rows in set (0.31 sec) What seems to be happening is that work is being sent to several computers and then the results are ignored, with no credit being assigned (granted_credit = 0). So right now two jobs' valid results are rejected and another two jobs are active somewhere else. What we would like to happen is to send a job to a single computer, wait for its completion (or failure, or expiry, etc.) and then generate another job if needed. We use the following parameters in the workunit: <target_nresults>1</target_nresults> <max_error_results>3</max_error_results> <max_success_results>1</max_success_results> <min_quorum>1</min_quorum> Any idea as to what has happened, and how we can get the desired behavior? Thanks. -Kamran _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address.
