Applications
• Text search (both exact and
approximate search)
• Encryption/decryption
• Structured record search
• Biosequence search
• Science data mining
• Signature hashing
Take Home Messages
• RASC incompatible with our
existing applications
− Initial focus of SGI was signal
processing apps.
− SGI currently altering RASC to
address our issues
• HW/SW interface is critical
− Port from Xeon to Opteron to
Itanium was straightforward
