| Num | Label | Milestone | Expected | Certified |
|---|---|---|---|---|
| 1. | A | Software engineering plan completed. Deliver software engineering plan, including software development plan, configuration management plan, and quality assurance plan. Appoint Review Board consisting of at least one NASA representative. |
06/02 | 07/02 |
| 2. | E | Global LDAS Code baseline completed. Baseline NOAH and CLM codes within the Global LDAS at 1/4 degree resolution on CT Testbed for near-term retrospective period. Initial version of documented source code made publicly available via the Web. Deliver initial versions of requirements document and software design documents via the Web. |
07/02 | 08/02 |
| 3. | B | First Annual Report delivered. Submit FY02 Annual Report to CT via Web. |
08/02 | 09/02 |
| 4. | O1 | Linux cluster installed. Install a Linux cluster at NASA/GSFC, consisting of two "queen" nodes and at least 192 "compute" nodes connected by at least Fast Ethernet. The queen nodes will support control and I/O functions and consist of dual 1.5 GHz processors, 4 GB RAM, and 2 TB storage or better. The compute nodes will support computations and consist of single 1.2 GHz processors, 512 MB RAM, and 80 GB storage or better. We anticipate gigabit connections between the compute node switches and the queen nodes as well as between the queen nodes and the GSFC network. |
08/02 | 09/02 |
| 5. | H | Design policy for interoperability and community delivery agreed on. Define and deliver documents defining interoperability and community requirements. Updated requirements document and design documents delivered via Web. Initial version of test plan delivered via Web. All documents submitted to Review Board. |
02/03 | 04/03 |
| 6. | F | First code improvement completed. Improve NOAH and CLM codes within the Global LDAS to operate at a 5 km horizontal spatial resolution with a throughput of approximately 1 ms per grid cell per day of execution on CT Testbed for near-term retrospective period. Provide code scaling curves via the Web. Documented source code made publicly available via the Web. |
03/03 | 04/03 |
| 7. | I | Interoperability prototype from Milestone H tested with improved codes. Demonstrate improved NOAH and CLM codes on the LIS Cluster installed in F. Demonstrate VIC code on CT Testbed and LIS cluster implemented according to H. Update Requirements, Design, and Test documents and deliver via Web. Submit initial Test Report for interoperability test. Submit initial User's Guide. All documents submitted to Review Board. |
07/03 | 10/03 |
| 8. | C | Second Annual Report delivered. Submit FY03 Annual Report to CT via Web. |
08/03 | 10/03 |
| 9. | G | Second code improvement completed. Implement the Land Information System (LIS) to integrate database and visualization functions with Global LDAS. Improve NOAH, VIC, and CLM codes within the Global LIS to operate at a 1 km horizontal spatial resolution with a throughput of approximately 0.4 ms per grid cell per day of execution (approximately a factor of 2.5 speedup) LIS cluster for near-term retrospective period. Provide code scaling curves via the Web. Documented source code made publicly available via the Web. |
02/04 | 07/04 |
| 10. | J | Full interoperability demonstrated using improved codes. Given that a prototype ESMF-compliant version of CLM is received by June 2003, implement the prototype ESMF-compliant version of CLM in the Global LIS and evaluate performance relative to milestones E, F, and G. Deliver documented source code via the Web, and submit updated documents to Review Board. |
07/04 | 10/04 |
| 11. | K | Customer delivery accomplished. Demonstrate LIS/ESMF functionality using ESMF-compliant version of CLM from milestone J as well as existing versions of CLM, NOAH, and VIC. Analyze predictive capability of the LIS using GrADS/DODS and Web interfaces, with users at NCEP, COLA, and universities. Submit updated Test Plans reflecting portability test, updated User's Guide, Maintenance Manual, and Requirements and Design documents. Present results to Review Board. Documented source code made publicly available via the Web. |
08/04 | 03/05 |
| 12 | D | Final Report delivered. Submit Final Report to CT via the Web. |
