3. CUG Cray SV1 Workshop Discussion Topics Operating System Support Plans UNICOS 10.0.0.7 Reminder UNICOS Plans (10.0.0.8 and 10.0.0.9) Tapes DMF Secure Shell (SSH) Gigabit Ethernet

4. CUG Cray SV1 Workshop Operating System Support Plans 200020012002200320042005 UNICOS 10.0 C90, J90 VME 1999 UNICOS 10.0 SV1 VME UNICOS 10.0 T90 (Model E) UNICOS For GigaRing Systems UNICOS/mk For T3E Systems Active Maintenance Mode Retired

5. CUG Cray SV1 Workshop UNICOS Support Modes Active Support –Software Releases with committed features –Publications (manuals, man pages, etc.) –Fixes for all severity levels Maintenance Mode –Software Updates; some features –Fixes focus on Critical and Urgent Retired –Critical-only help via support contract

6. CUG Cray SV1 Workshop UNICOS 10.0.0.7 Reminder Dynamic MSP –Configured maximum for system –Created and dissolved by the kernel based on demand –Users can gang-schedule autotasked codes via /etc/cpu command

7. CUG Cray SV1 Workshop UNICOS 10.0.0.8 Planned Release 12/2000 SV1e CPU Support (pre-hardware) I/O Module Support (P-SV1-IO-MODULE) Networking Threads Interrupt Processor Selection Resiliency Changes Faster downing of failing CPUs Reclamation of process memory assigned to down CPU Conditional freeing of process locks

8. CUG Cray SV1 Workshop UNICOS 10.0.0.9 Planned Release 2Q2001 SV1ex Extended Memory Support –Transparent SSD Support (Model E “model”) SSD Resident NC1 Filesystems Ldcache Fast Swap Secondary Data Segments (SDS) –I/O Changes for Optimum Backdoor-like Capability (SuperRing) General Kernel Performance

9. CUG Cray SV1 Workshop UNICOS Tape Support Tested/Supported with UNICOS 10.0.0.8 –STK 9840 SCSI and Escon –IBM 3590E SCSI and Escon (A60) –Quantum DLT8000 Planning Support of: –STK 9940 Escon (3590 Emulation) –STK L700 Library Fibre Channel Research

10. CUG Cray SV1 Workshop Cray DMF Cray has the rights to support/enhance DMF 2.5 on Cray platforms Cray will actively support DMF 2.5 for as long as we support UNICOS Cray does not have the rights to the SGI-development version DMF (3.0) Future: –Investigate possible DMF 3.0. Client –Look for winning standard for HSM support

11. CUG Cray SV1 Workshop Secure Shell (SSH) Resource hired to port and support SSH on UNICOS OpenSSH is the likely candidate No decision yet on method for release (encryption algorithms), license or support fees Planned availability is 2Q2001 but will depend on release vehicle

12. CUG Cray SV1 Workshop Gigabit Ethernet Working with Essential Communications to provide a Layer 7 Router (L7R) solution for UNICOS Connection requires HIPPI Early Beta-test performance seen on an SV1 for TCP: –~250 Mb/s at 1500 Byte MTUs –~350 Mb/s at 9K Byte MTUs Planned availability 1Q2001
