3. Exec Comm 8/20/98Millennium3 Committments Intel provides 6 M$ in equipment Sun provides all Solaris x86 software Microsoft provides all NT software Campus provides staff to support the core infrastructure, networking CS will try to raise funds for the network and campus cluster infra. Departments provide 1/2 of system admin for own side and 20 K$ for group cluster –racks, network, software,...

4. Exec Comm 8/20/98Millennium4 Where are we? Hardware deployment Software availability Cluster Environment Grants Networking

5. Exec Comm 8/20/98Millennium5 Current Environment All projects have servers and several desktops –last few in current shipment millennium.berkeley.edu domain established solaris shared servers with 60GB disks –www.millennium.berkeley.edu, MM.millennium.berkeley.edu –imap,... solaris/x86 sww served from CS servers NT domain server with 60 GB disks –MMNT.millennium.berkeley.edu –exchange, file,... First cluster ready for use NSF SimMillennium grant to cover network Two of three Millennium staff hired

6. Exec Comm 8/20/98Millennium6 Hardware Deployment

7. Exec Comm 8/20/98Millennium7 Basic Software Tools Standard Unix Tools /usr/sww/bin –484 packages GNU Tools –gcc, g++ (version 2.8.1), gdb, g... Sun ProWorks –workshop “development environment” –C, C++, F77 –Debugger Sun Performance Library/usr/sww/lib Sun Math Library

8. Exec Comm 8/20/98Millennium8 Cluster Developments 4 x 4 PentiumPro Cluster ready Full NOW environment –Glunix, MPI, Active Messages, Split-C –titanium protoype Transfering to Cory to debug deployment CS / Civil Eng. Consortium has been shaking it out –petc graph partitioner, finite element classes, … –ScaLapack (???) Have parts for three 8x2 Pentium II clusters –AstroPhysics –Soda Solaris x86 to be shipped out –Soda NT cluster

9. Exec Comm 8/20/98Millennium9 Grants NSF CISE Research Infrastructure grant –cluster networking –inter-cluster networking (campus mgmt) –computational economy staff support –visualization –devoted to CS research with disciplinary applns Bay Networks 70% discount up to 5 M$ –gigabit networks IBM SUR disk towers IBM CS extension to PDA access NSF Science and Tech. Centers in process … any more???

10. Exec Comm 8/20/98Millennium10 Networking Campus using Millennium to drive planning CNS is working closely with us. Testing gigabit ethernet Campbell, Evans, Davis moving forward CS will be able to cover the intracluster network (Myrinet) and gigabit switch in the group clusters –frees up some of the committed resources

11. Exec Comm 8/20/98Millennium11 Going forward Roll out group clusters over next few quarters Roll out gigabit interconnect Build up the cluster programming tools Intel Merced pushed out –campus cluster delayed –utilize NOW as an alternative –combine with NPACI infrastructure Exploring cluster technology –VIA –Synfinity, ServerNet, Gigabit Ethernet Exploring NT
