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

LIME Packaging

• MIME gtgt DIME gtgt LIME
• Very simple. Allows 264 bytes
• File consists of messages
• Message consists of records
• Record consists of a header and data
• Header includes a content type label
