Red Hat Bugzilla – Bug 451799
upfront construction of ec2 KeyPairs is time consuming
Last modified: 2008-10-07 14:42:25 EDT
The gridmanager will construct KeyPairs for all outstanding EC2 jobs upfront.
This can lead to a delay in starting jobs when there are many (10K for instance)
EC2 jobs queued.
This is fixed in the V7_1 branch. The construction of keypairs is now restricted by the gridmanager's submission throttles.
This is tested by submitting a set of 100 jobs (any number greater than GRIDMANAGER_MAX_SUBMITTED_JOBS_PER_RESOURCE will work), and after some begin to run check the set of created keypairs with ec2-describe-keypairs. If there are more keypairs than running jobs this issue still exists.
