LHC@home

Hi everyone,

i have a little problem, i didn't had before:
LHC@home - 2006-01-15 02:26:43 - Sending request to scheduler: http://lhcathome-sched1.cern.ch/scheduler/cgi
LHC@home - 2006-01-15 02:26:46 - Scheduler RPC to http://lhcathome-sched1.cern.ch/scheduler/cgi succeeded
LHC@home - 2006-01-15 02:26:46 - Message from server: No work sent (there was work but you don't have enough disk space allocated) Not enough disk space (only 22.7 MB free for BOINC). Review preferences for minimum disk free space allowed.
LHC@home - 2006-01-15 02:26:46 - No work from project
LHC@home - 2006-01-15 02:26:46 - Deferring communication with project for 1 days, 0 hours, 0 minutes, and 0 seconds
I run BOINC on a 160 MB Ramdisk on a notebook, because of overheating from normal disk. This has been functional since > a year... Now, after the XMas outage it suddenly complains about not enough disk space :? There are ~120 MB of Ramdisk free??? So what is the problem???

It could be because of your disk preferences, take a look at your "disk and memory usage" under your general preferences: http://lhcathome.cern.ch/prefs.php?subset=global.

BOINC.BE: The team for Belgians and their friends who love the smell of glowing red cpu's in the morning

Sorry, but at Einstein this also was the first (wrong) answer (Einstein corrected it at their end!!, not mine!):

My preferences are as follows since > 1 year !!!
Do work while computer is running on batteries?
(matters only for portable computers) no
Do work while computer is in use? yes
Do work only between the hours of (no restriction)
Leave applications in memory while preempted?
(suspended applications will consume swap space if 'yes') yes
Switch between applications every
(recommended: 60 minutes) 60 minutes
On multiprocessors, use at most 1 processors
Disk and memory usage
Use no more than 0.16 GB disk space
Leave at least 0.001 GB disk space free
Use no more than 99% of total disk space
Write to disk at most every 60 seconds
Use no more than 75% of total virtual memory
Network usage
Connect to network about every
(determines size of work cache; maximum 10 days) 1.5 days
Confirm before connecting to Internet?
(matters only if you use a modem) yes
Disconnect when done?
(matters only if you use a modem) no
Maximum download rate: no limit
Maximum upload rate: no limit
Use network only between the hours of
Enforced by versions 4.46 and greater (no restriction)
Skip image file verification?
Check this ONLY if your Internet provider modifies image files (UMTS does this, for example).
Skipping verification reduces the security of BOINC. no


So, what has changed and is the problem now? At Einstein it was their end, not mine!!

Just a bit low if you ask me.....

Use no more than 0.16 GB disk space

... it's a 160 MByte RAM-disk ;)

Does not matter. Once it is full, it is full and you won't get work. If it is BOINC only, set the parms to use it all ... leave any free to 0 ... but, if you are running Einstein@Home or CPDN that is way too small ...

For CPDN it's way too low but for Einstein, Seti and LHC it was always fine until now :/
And setting 'leave at least...' to 0 was absolutely false, cause it was interpreted as 100MB. So the guys at Einstein recommended setting it to 0.001 ;)

Guess i'll have to try with 224 MB, but i really don't like to do that...

[edit] It is far from full. There are ~120 MBytes free...

Walt G. made a long write up about that ... I added it to the disk space messages ... you might want to look up that discussion and see if anything there helps ...
