  • ITAPS telecon: Thursday 12pm-1pm
  • iMeshP compliance test verification with FMDB pended due to incomplete implementation such as ghosting & multiple part per process
  • entity group migration with "splitted" entity data stream won't be considered to put into the repository
    Instead, better algorithm for migration procedure will be investigated.

FMDB Weekly #45 (Nov 8 - Nov 12)

Added by E. Seegyoung Seol almost 7 years ago

[ Week 45 Activities ]

FMDB v1.1
  • (on-going) ghosting improvement:
    - implemented 1-layer ghosting with mixed topologies
    - 1-layer unit test and debugging
  • (on-going) reducing memory cost of mesh entity
  • (on-going) code clean-up and restructuring
    - test folder: FMDB.h testing, migration/loadbalance testing, imesh/imeshp compliance testing
ITAPS
  • (on-going) iRel spec proposal for better classification support
  • (on-going) iMesh_FMDB improvement
Mesh Converter
  • NONE

[ Planned Week 46 Activities ]

FMDB v1.1
  • ghosting improvement
    - n-layer ghosting
    - time & memory cost comparison
  • improving mesh entity memory cost
  • efficiency improvement and debugging
    - 1st/2nd order adjacency
ITAPS
  • iRel spec proposal for better classification support
  • iMesh: improving iMesh-FMDB implementation
iMeshIO/Mesh Converter

[ Pended Issues ]

  • FMDB
    - regression testing suite incorporated with Automake and Nightly Build
    - local partitioning (requestor: Min)
    - FMDB.h consolidation
    - automatic attached data migration
    - merging entity group with entity set
    - improved algorithm for migration procedure
    - Exodus II mesh format (requestor: Sandia)
  • FMDB/iMesh(P)
    - iMesh entity handle validity check
    - iMesh entity set file I/O
    - iMeshP implmentation: linking with iZoltan
    - iMeshP compliance test: standardized autotool options
    - distributed vtk file I/O with partition info
  • GMI/iGeom
    - incorporating with SCOREC entity set and iterator
    - implementing GMI.h
    - removing FMDB dependency
  • GUM/iBase
    - source reorganization to take out of FMDB project
    - implementing GUM.h
    - removing FMDB dependency
  • GRM/iRel
    - NONE
  • MeshAdapt
    - incorporating decision procedure to compute partition objects to migrate before calling FMDB::M_migrate
  • Miscellaneous
    - SCOREC S/W web page update
    - Doxygen
