Not entirely sure what's the root of this, but when using image transfers the availability window doesn't seem to get properly cached. This fix seems to shave ~30% off the time it takes to run the simulations that involve image transfers.
Preparation scheduling for AR leases was broken. THere were cases when it would schedule an image transfer that was actually infeasible.
Since preparation scheduling can result in an infeasible lease, preemptions should be done after the preparation has been scheduled.
Fixed wrong handling of attributes in multiconfig files
haizea-convert-data now supports data files with different sets of attributes/metrics (files without a given attribute/metric just report it as an empty string)
- Modified LWF generator so it won't have an empty ramp-up period.- Minor fixes here and there.
Fixed bug when determining the "first start" of a VMRR. Shouldn't include the migration RRs.
Fix bug in availability window optimization
Fixed some bugs in optimization. Added a flag to turn it off (albeit in a kludgy way), because otherwise the slottable unit tests get confused.
More optimizations
A few optimizations (still need to be polished a bit)
Fixed uninitialized variable
Added option to interrupt simulation after a given amount of (simulated) time has passed.
Bug: lease/lease.id confusion
Another error-propagation bug in estimating times.
- In some cases an error was carried over in the estimated migration times that would result in the sanity check failing.- Migration bandwidth was hardcoded; now taken from configuration file.
Minor fixes
Several bug fixes in unit tests. Some of the deadline tests are currently still failing.
- Changed unit tests to use test_* functions instead of Test* classes. Newer py.test is apparently not too happy about test classes having a constructor.- Minor changes.
More small bug fixes
