Current Holdings• Existing
– 733 SDMs• 6 Salamanders• 62 Birds• 7 Diatoms• 2 Fishes• 167 Invertebrates• 4 Mammals• 484 Plants• 1 Slime Mold
• Upcoming– 1,420 SDMs– 2 new
environmental variables • Temperature• Soil pH
– New taxa• Reptiles
1024 Cores, can run the MaxEnt Java program (Titan cannot)
Parallel Processing

Next Steps• Workflow– More automation
• Web services
– Engage “Non-traditional” HPC users
• Access– Advanced
• Raw data output
– Intermediate• Map interface• Synthesized data
products
– Casual• Exploratory use
