World Community Grid - View Thread - An option to force a checkpoint would be invaluable

Okay so my server is an HP proliant DL385 and does not allow for suspend or hibernate. I'm running ubuntu on it.

So I went away and wrote a small bash script to run in the evening to wait for the ARP unit to go past the next checkpoint, then poweroff.

Here's my script if it helps anyone. Note that I currently only allow for 1 ARP unit at a time, so the script would need an update to cater for more than 1.

#!/bin/bash

# find the africa rainfall project. It checkpoints every 12.5%. Need to ensure we don't can it before it's checkpointed
a=`boinccmd --get_tasks | grep "name: ARP" -A15 | grep "active_task_state: EXECUTING" -A9 | grep "CPU time at last checkpoint: " | grep -Eo '[+-]?[0-9]+([.][0-9]+)?'`

if [ -z "$a"]
then
echo "No africa rainforest project running, powering off now"
/sbin/poweroff
exit 0
fi

echo "Original checkpoint time at $a seconds. Waiting for that to change indicating a new checkpoint"

b=`boinccmd --get_tasks | grep "name: ARP" -A15 | grep "active_task_state: EXECUTING" -A9 | grep "CPU time at last checkpoint: " | grep -Eo '[+-]?[0-9]+([.][0-9]+)?'`
until [ 0 -eq "$(echo "${b} == ${a}" | bc)" ]
do
sleep 120
b=`boinccmd --get_tasks | grep "name: ARP" -A15 | grep "active_task_state: EXECUTING" -A9 | grep "CPU time at last checkpoint: " | grep -Eo '[+-]?[0-9]+([.][0-9]+)?'`
done

echo "New checkpoint at $b seconds, all done :-)"
/sbin/poweroff
