1. HDF5 for Real-Time and/or Embedded Test Data

2. Flight tests have multiple data sources
Communications aircraft
Aircraft
Non-time based data
Can have many data sources for a single event.
Need different data rates, content, views of data.
Calibration
Satellite/GPS
Documents
Video
Automobile testing
Voice communications
HDF5 lets us manage those sources,
mixing all types of information
In a single file
HDF5 supports different views, access patterns, fast I/O all in one package.
Ground tracking

Current testing applications use different formats, develop codes independently.
HDF5 lets us share tools and analysis codes, saving effort and cost.

4. Task 1: Fixed & variable length record storage, access
Data
Variable-length data records
Time . .
Data
Fixed-length data records
Time
Need simple, efficient API for a range of applications and environments.
HDF5-based storage and API will yield cost savings, ultimately leading to standardized formats, software, tools.
Records can be fixed or variable in length. Variable-length records can vary in size & content per time step.

5. Tasks
Make the HDF5 Table API efficiently support fixed and variable length time-sequenced test data in a way that works across a range of applications and environments.
Support horizontal view during collection, and vertical views during analysis
Handle high I/O data rates, and high volume
Accommodate multiple streams
Deal with dropouts
