Job class variants - They will help to keep the effort in configuring job classes small. The template job class - This job class might be used to enforce settings for all other job classes in a system.

Defining Job Classes as Templates for Jobs

Engineers improving Univa Grid Engine use an automated test environment during the development and during the test phase before a new version of Univa Grid Engine is released. This test suite automatically installs test clusters and runs several thousand test scenarios to see if functionality of Univa Grid Engine is broken.

For each bug that is fixed in the Univa Grid Engine code base a new test scenario is added to the test suite and also when new functionality is implemented then engineers have to create new tests to keep the test coverage high.

Today I have finished the 91st test scenario that tests job class functionality. Some of these new tests take care that the ownership of a job class is respected and some validate that the code is working correctly that should prevent users from deriving new jobs from job classes that do not allow this. Ownership and accessibility are two characteristics that have to be defined when new job classes are created in Univa Grid Engine 8.1.
