MPU Meeting Tuesday 7th October 2008
Buildtools Project
At Alastair's request Stephen has added a cmake function to install templates in a particular location.
Other than that, Stephen has altered and submitted more components.
Chris commented on
http://www.lcfg.org/doc/buildtools/reltool.html - he agreed with Stephen's comments on the
release command and suggested that Stephen should seize this opportunity to improve the terminology by renaming the command to
micro, perhaps adding a replacement
release command which spits out a message directing the user to the
micro command.
Power Management Project
The component now identifies the next due cron job and sets the machine's wake-up time to slightly before this job's date/time.
Chris has talked to Iain about Sleep/Condor integration and it seems that it'll be pretty simple - the machine will just have to
- stay up for a few minutes at a time before going back to sleep - as Condor clients check with the pool master every 2-3 minutes.
- wake up say every three hours, to give Condor the chance to grab any suitable waiting jobs.
- Check for the presence of a Condor job as one of the checks to be made when assessing whether sleep is currently a good idea.
Stephen and Alastair suggested broadening this latter check to provide some sort of general hook mechanism so that users at different sites could add their own tests for sleep.
LCFG Component Testing Project
The proposal is two thirds written and Stephen is waiting patiently for comments from MPU.
Project Prioritisation
We'll hold a special meeting to discuss this in Alastair's office at 10am on Thursday.
Operational
- DIY DICE Docs
- Alastair has created an entry for it in http://www.inf.ed.ac.uk/systems/ - this links to a wiki page which gathers together all of the documentation. The install guide is now up to date and the process is far simpler than it used to be. There's still more tidying up to do in the documentation.
- New Inventory
- the next stage, sometime this week, will be for Stephen to change all
inv
entries in LCFG source files to use mutation macros. At a later stage these settings will be eliminated altogether and the inventory data will come from the inventory database. This may happen in perhaps a couple of weeks. Eventually the only inventory item that the CSOs will need to set (in the database) will be the machine's allocation - everything else will be automatically derived. In particular the location data will come from network data. However this raises questions so Alastair will talk to Ken about:
- Making sure that everyone will know in good time how to use the inventory database
- The difference between where the machine is and where the machine should be, and the apparent worrying shift in meaning of our inventory location data from the latter to the former.
- qxpack
- Stephen has implemented Kenny's requested change (that
qxpack
should exit with a non-zero code when a match is not found for a package name).
- Mutation bug fix
- Stephen has fixed a bug in mEXTRA and mAPPEND which made them obliterate any previous values in mutated resources when those previous values evaluated to false. The fix will go in on Friday morning but will cause a big rebuild.
- Flickery screens
- After some discussion, Chris will try removing xfree's
vberestore
settings on his and Carol's machines gothenburg and ardoch to see if that solves the flickery screen problem (where an unusable white flickering sometimes appears instead of the GDM login screen - been happening for a couple of weeks now).
