4. 4 For the first time in a long time… The most powerful supercomputers on the planet… Enables applications at over a sustained petaflops and… can also run your key ISV applications. ® ® ® ®

5. 5 Benefits of CLE3 and Cray’s Adaptive Supercomputing Vision Performance: Support ultimate scalability Scalability to run sustained petascale applications New storage and IO features with improved Lustre support Improved scheduler features and support Better high-multicore node support with “Core Specialization” Reliability: Industry-leading system availability Node health checking with “Advanced NodeKARE” Improved network resiliency Improved serviceability and node replacement Compatibility: Industry-standard OS base SUSE base linux Improved parallel IO support with “Data Virtualization Service (DVS)” Introducing CCM – Cluster Compatibility Mode Flexibility: OS adapts at job runtime Extreme Scalability Mode and Cluster Compatibility Mode Cray Inc

6. 6 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 Cray Inc

7. Many Applications running in Extreme Scalability Mode (ESM) Submit CCM application through Batch Scheduler, nodes reserved qsub -q ccm Qname AppScript Nodes assigned by batch SW and configured for CCM Executes the batch script and Application Other nodes scheduled for ESM or CCM applications as available After CCM job completes, CCM nodes cleared CCM nodes available for ESM or CCM mode Applications Slide 7 Cray XT6/Baker System Service Nodes Compute Nodes CCM Mode Running ESM Mode Running ESM Mode Idle Cray Inc

8. Install out of the box No changes to install procedure Install on shared storage Any globally shared storage available on the compute nodes Supports networked licenses 8 Cray Inc
