ADTS
IPoIB
• Application performance for FTP
get
operation for disk based transfers
• Community Climate System Model
(CCSM)
• Part of Earth System Grid Project
• Transfers 160 TB of total data in
chunks of 256 MB
• Network latency - 30 ms
• Ultra-Scale Visualization (Ultra-Viz)
• Transfers files of size 2.6 GB
• Network latency - 80 ms
The ADTS driver out performs the UDT driver using IPoIB by more than
100%
