---|
[1651] | 9 | From ANU: Stephen, Matt, Linda |
---|
| 10 | From GA: Ole, Andrew |

---|
| 13 | 1: Parallelisation of pyvolution |
---|
| 14 | |
---|
| 15 | The current contract is essentially completed. |
---|
| 16 | However, a few remaining loose ends will be given some further |
---|
| 17 | attention over the next months. They are |
---|
| 18 | |
---|
| 19 | - fluxes in ghostcells should not affect timestep computation. |
---|
| 20 | - a function for re-assembling model output should be made available |
---|
| 21 | |
---|
| 22 | |
---|
| 23 | Ideas for a second contract include: |
---|
| 24 | |
---|
| 25 | - scoping of methodologies for automatic domain decomposition |
---|
| 26 | - implementation of automatic domain decomposition |
---|
| 27 | (using C extensions for maximal sequential performance in order to minimise |
---|
| 28 | performance penalties due to Amdahl's law) |
---|
| 29 | - in depth testing and tuning of parallel performane. This may require |
---|
| 30 | adding wrappers for non-blocking MPI communication to pypar if needed. |
---|
| 31 | - ability to read in precomputed sub-domains. Perhaps using caching.py |
---|
| 32 | |
---|
[1651] | 33 | We will iterate on these ideas and arrive at a mutually beneficial |
---|
| 34 | contract to be carried out in early 2006 |
---|
[1649] | 35 | |
---|
| 36 | |
---|
| 37 | |
---|
| 38 | 2: Validation of pyvolution |
---|
| 39 | |
---|
[1650] | 40 | Laboratory Data: |
---|
[1651] | 41 | Benchmark data from wave tank experiments were deemed suitable for |
---|
| 42 | initial validation exercises and we should proceed with these |
---|
| 43 | immediately using the existing acquired datasets. In addition, data |
---|
| 44 | from vertical wall run-ups will be relevant. Andrew's letter to key |
---|
| 45 | players regarding other existing laboratory datasets is deemed |
---|
| 46 | extremely valuable and should go ahead. |
---|
[1649] | 47 | |
---|
| 48 | |
---|
| 49 | Historical Data: |
---|
[1651] | 50 | Andrew has contacted relevant organisations regarding sources and |
---|
| 51 | availability of existing post-tsunami field survey data. We agreed |
---|
| 52 | that a scenario from e.g. Banda Aceh or Thailand (Phuket) |
---|
| 53 | demonstrating the detailed effect of bathymetric variations would be |
---|
| 54 | an ideal study and could form the basis of a scientific paper. Matt is |
---|
| 55 | considering whether this would fit into his research priorities. |
---|
[1649] | 56 | |
---|
| 57 | |
---|
| 58 | Other: |
---|
| 59 | Validation against analytical solutions is well under way and |
---|
| 60 | is considered an integral component of the validation process. |
---|
| 61 | The same is true for the Lake Merimbula tidal validation project. |
---|
| 62 | Stephen and Chris are looking after these. |
---|
| 63 | |
---|
| 64 | |
---|
| 65 | Contacts: |
---|
| 66 | |
---|
[1651] | 67 | Ole will take contact with Lex Nielsen from SMEC in order to explore |
---|
| 68 | how they can get involved |
---|
[1649] | 69 | |
---|
| 70 | We will also establish a closer relationship with Lutz fram ACcESS |
---|
| 71 | |
---|
[1651] | 72 | Andrew to contact key researchers/organisation to enquire about and |
---|
| 73 | potentially acquire further laboratory and field survey datasets. |
---|
[1649] | 74 | |
---|
| 75 | |
---|
| 76 | |
---|
| 77 | |
---|
| 78 | 3: Other collaborations |
---|
| 79 | |
---|
| 80 | Ole to investigate if GA would fund a PhD student: Project could be |
---|
| 81 | "Algorithms for augmentation of unstructured grids" or "Algorithms for |
---|
| 82 | unification of geodesic systems in unstructured grids" the latter |
---|
| 83 | capturing the notion of being able to model the synoptic, deep water |
---|
| 84 | wave propagation in latitudes and longitudes with a seemless connection |
---|
| 85 | to detailed modelling using UTM projections. |
---|
[1650] | 86 | A PhD scholarship is worth about $20K per annum. |
---|
[1649] | 87 | |
---|
| 88 | |
---|
| 89 | |
---|
| 90 | 4 Long term aim |
---|
| 91 | |
---|
| 92 | We agreed that having a detailed, reproducible and validated |
---|
| 93 | inundation scenario from the Boxing Day Tsunami running in parallel |
---|
| 94 | (and being faster than the sequential code) would be a worthwhile goal. |
---|
