Milestone | Task | Who | Effort (expected) | Effort (pessimistic) | Dependency | Target Date | Confidence Level (, , ) | Completed | Comments |
---|---|---|---|---|---|---|---|---|---|
M1 | Setup | ~1 day (M1.1 + 1.2 + 1.3) | ~1 week (M1.1 + 1.2 + 1.3) | When JEP is Funded | Funded: 2013/06/10 notification

M1.1 | Staging repository setup | Oracle | Few hours | 1 day | At request of Lead | When JEP is Funded | 2013/06/10 | ||
M1.2 | JIRA CPU and OS updates | Oracle | Few hours | 1 day | After M1.1 | July 2013 | 2013/07/12 | OS value "aix" added. New CPU field unnecessary. The following fields should be updated. OS would have a new field 'aix' with optionally adding version post fix such as 'aix_7.1' or 'aix_6'. The CPU would have a new field 'ppc64'. | |
M1.3 | Hudson instance on staging server | Oracle | Few hours | 1 day | After M1.1 | July 2013 | 2013/08/01 | ||
M2 | Review and approve initial set of changes | ~4 weeks | ~6 weeks | After M1 | 2013/11/28 | The work can happen mostly in parallel, with M2.1 and M2.2 taking roughly the same time to complete as M2.3. | |||
M2.1 | Review changes for a working linux_ppc64 hotspot port | Oracle, SAP, IBM | ~2 weeks | ~3 weeks | After M1.3 | Mid-Late August | 2013/08/20 | The initial 8 changes (1-8) that get a working linux_ppc64 port | |
M2.2 | Review changes for a working aix_ppc64 hotspot port | Oracle, SAP, IBM | ~2 weeks | ~3 weeks | After M1.3 | Mid-Late August | 2013/09/06 | The next set of patches (9-13) to get a working aix_ppc64 port | |
