A relatively new switch fraction_done_exact, has been implemented in BOINC effective on versions starting (and including) 7.3.13 Don't waste your time trying this with earlier versions of BOINC, you must be running 7.3.13 inclusive or above. (if you ever needed a "push" to update your BOINC Client, this is definitely it rofl :) )

This switch eliminates a long standing BOINC frustration whereby the "time remaining" part of the calculation metric on WUs was always way,way out when starting a "new" class of WUs. The latter problem has arguably caused the most amount of angst, hassle and comment on any aspect of the stats side in the History of BOINC. This, at last, plugs that long standing grief.

The switch will ensure the second part of the classic time statements showing in BOINC Manager state's reality, and at last gets round the horrible second timing that has caused so much confusion over the years (time remaining to completion)

To implement the switch, place it inside the app_config of each machine running. A simplistic representation of an app_config is shown below, with the place to insert the switch. Once you have done so, click "BOINC Manager - Advanced - Read Config files" to get it going for the running files, it will in any case auto-start on the startup of the next WU to be crunched.

<app_config>

<app>
<name>solo_collatz</name>
<max_concurrent>2</max_concurrent>
<fraction_done_exact/>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>0.5</cpu_usage>
</gpu_versions>
</app>

</app_config>

Tonight, burn some incense in honour of BOINC for - at last - plugging this long standing irritation, and stops BOINC "lying" ......

Progress indeed ...... :)

I added it to the server so anyone running 7.3.13 or later should not need an app_config.xml in order for it to work. That's the theory anyway.
