minimum quorum 2
initial replication 2

in case of an error, a new task is generated but is not sent to clients, it waits in the queue of the scheduler

repeat tasks need to be prioritized over new tasks

Ah yeah, I agree. Any idea how to implement this?

The transitioner should do this automatically and send it back to the feeder. You can probably play with the feeder's commands for this.

I guess this still needs to be addressed - there are still lots of "validation pending" units, where the validation unit has not been sent out.

Perhaps the issue is made worse by having 230,356 tasks already in the queue ready to send. With a pool that large, it may take many days for the resends to get issued.

Yeah, I'm still looking into this, I assume there's a solution without just reducing the pool size.

As always, you can email the BOINC developers email list or the BOINC Projects email list (or both). No need to reinvent BOINC or try to do everything alone.

We've taken a few manual steps to reprioritize jobs which were created as a result of a computation error. This will be running as a 3 hourly task:

while read line; do
    if [[ "$(echo "${line}" | awk '{print $2}')" -lt 2 ]]; then
        mysql -D minecrafthome -s -N -e " \
            UPDATE result \
            SET priority = 1 \
            WHERE id = $(echo ${line} | awk '{print $1}')"
    fi
done <<< $(mysql -D minecrafthome -s -N -e " \
    SELECT id, COUNT(workunitid) \
    FROM result \
    WHERE server_state = 2 AND priority = 0 AND workunitid in \
        (SELECT * FROM \
             (SELECT workunitid \
              FROM result \
              GROUP by workunitid \
              HAVING COUNT(workunitid) > 2) \
         AS a) \
    GROUP BY workunitid;")
