Global_Prefs_Override.xml will do preferences higher than 100%

[Ageless]

Something that came up through the Seti forums. An interesting bug, which seems to apply to all BOINC 6 versions.

When setting the preferences through the Local Advanced Preferences menu and setting the amount of CPUs to use to something higher than 100%, this setting is saved in the global_prefs_override.xml file. This bug works on all preferences where percentages are used.

Here's the excerpt of the global_prefs_override.xml file for the defect:

<global_preferences>
   <max_ncpus_pct>7542.000000</max_ncpus_pct>
   <ram_max_used_busy_pct>7523.000000</ram_max_used_busy_pct>
   <ram_max_used_idle_pct>9532.000000</ram_max_used_idle_pct>
   <vm_max_used_pct>546332.000000</vm_max_used_pct>
   <cpu_usage_limit>9832.000000</cpu_usage_limit>
</global_preferences>

Check the memory percentages I set. This translates in BOINC to:

08-Dec-08 02:29:34||Preferences limit memory usage when active to 154013.15MB
08-Dec-08 02:29:34||Preferences limit memory usage when idle to 195142.01MB

Cool... I only have 2GB and a 32bit OS... :-)

When I go back into the preferences menu, the percentages for the CPUs and throttle have reset, but for the memory and virtual memory settings the percentages stay at those high numbers.

I am not sure if it affects BOINC badly in any way, but a check is in order that resets the percentage written to the file to 100 if the number is over 100.

Hmm, best set CC to me and assign to David. :-)

typo.

(In [16645]) - manager: clamp percentages at [0,100] in prefs dialog

fixes #794

• wrapper: if app checkpoints, write CPU time to checkpoint file

fixes #792 (I hope)
