• No compromise scalability• Low-Noise Kernel for scalability• Native Comm. & Optimized MPI• Application-specific performance
tuning and scaling
ESM – Extreme Scalability Mode
• No compromise compatibility• Fully standard x86/Linux• Standardized Communication Layer• Out-of-the-box ISV Installation• ISV applications simply install and run
CCM –Cluster Compatibility Mode
CLE3 run mode is set by the user on a job-by-job basis to provide full flexibility
