AMR Interoperability Aplication Programming Interfaces

1.0

Data Aliasing:

See also:

AMRData.h

• Problem
  • The largest impediment to interoperability of various Structured AMR efforts within the DOE (and beyond) are related to data description.

• Goal
  • Provide a community-standard interface for describing Structured AMR data sets and associated data structures.
  • Enable different community members to focus efforts on component development without suffering from data-conversion losses (performance and memory).
  • examples: Chombo Elliptic Solver Component, AMR-HDF5 File IO Component.

• Approach
  • A API written in ANSI-C for client components to describe their AMR data sets to server components.

AMR-HDF5 Interface

See also:

AMR-HDF5.h

• HDF5
  • portable binary files.
  • supports additional meta data for specific application domains.
  • hyper-slab. (out-of-core tools). Ability to read in specific component of a specific box.
  • parallel I/O support on most platforms.

• readable/(writable) by ChomboVis
• File organization
  • component names
  • grid spacing
  • centerings
  • dimensions
  • data organized as levels of grids
  • parallel neutral (but contains processor assignments from when the file was written)
