UNICOS Support ModesUNICOS 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

UNICOS 10.0.0.7UNICOS 10.0.0.7ReminderReminder
• Dynamic MSP– Configured maximum for system– Created and dissolved by the kernel based
on demand– Users can gang-schedule autotasked
codesvia /etc/cpu command
CUG Cray SV1 Workshop
UNICOS 10.0.0.8 UNICOS 10.0.0.8 Planned Release 12/2000Planned 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

UNICOS 10.0.0.9UNICOS 10.0.0.9Planned Release 2Q2001Planned 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-likeCapability (SuperRing)
• General Kernel Performance

UNICOS Tape SupportUNICOS 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
CUG Cray SV1 Workshop
Cray DMFCray DMF
• Cray has the rights to support/enhanceDMF 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
CUG Cray SV1 Workshop
Secure Shell (SSH)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 willdepend on release vehicle
CUG Cray SV1 Workshop
Gigabit EthernetGigabit Ethernet
• Working with Essential Communicationsto 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
