1. ILDG Implementation Status
Carleton DeTar
University of Utah
ILDG-5

2. SciDAC File Format Supports metadata and binary data
Supports lattice fields and “global” data
Tries to anticipate ILDG needs
Open software QIO/LIME
In production use by LHPC

3. LIME Packaging MIME >> DIME >> LIME
Very simple. Allows 2^64 bytes
File consists of messages
Message consists of records
Record consists of a header and data
Header includes a content type label

4. SciDAC Gauge Configuration File
Private file header
User file XML (not standardized, yet)
Private record header
User record XML (not standardized)
Binary data in NERSC 3x3 format
SciDAC Checksum

5. ILDG Compatibility Propose LIME packaging
Could add ILDG format metadata
Could add QCDML
Could add BinX record
Can do propagators or other fields
