1. Garden of Architectures CSG Workshop May 2008 Jim Pepin CTO

2. Disruptive change Doubling (Moore’s Law or …) –Transistors Multi-core –Disk capacity –New mass storage (flash, etc) –Parallel apps –Storage mgmt –Optics based networking

3. Disruptive Change Federated identity –Large V/O –Shared research/clinical spaces Team science/academics –Paradigm shift CI as a tool for all scholarship

4. Disruptive Change Lack of diversity in computing architectures –X64 has ‘won’ Maybe IBM/Power exists at edges Maybe Sun/SPARC at edges –This creates mono-culture Dangerous –Innovation here in consumer space Game boxes/phones drive here

5. Network Futures Optical Bypasses –Very high speed Low friction Low jitter Facilities based –GLIF examples –RONs –Exchanges

6. Network Futures “Security” is driving researchers away from us Are we the problem? –Where does ‘security’ belong? How do we do VOs with two port internet? Will we see our networks become ‘campus phone switch’ of the 2010s

7. Data futures Massive storage (really really big) Object oriented (in some cases) Preservation Provenance Distributed Blur between data bases/file systems –Meta data

8. New Operating Environments Operating systems in network –Grids ID management –But done poorly from integration view How to build petascale single systems –Scaling applications is biggest problem Training “Cargo Cult” systems and applications

9. New Operating Environments 100s of TF at campus (but how to use it and build it on campus) –Tied into national petascale systems –All the problems on terragrid and VOs on steroids. Network security friction points Identity management Non-homogenous operating environments

10. Computation Massively parallel –Many cores (doubling every 2-3 yrs) Commodity parts –Massive collections of nodes with high speed interconnect Heat and power density Optical on chip technology –Legacy code scales performs poorly (or worse)

11. Viz/remote access SHDTV like quality (4k) –Enables true telemedicine and robotic surgery –Massive storage ties to this –Optiputer project is example (CALIT2) –Colab spaces with true haptic and visual presence. Social sites are simple prototypes Large screen applications and tele-presence

12. Versus Old Code –Much based on 360/VAX/Name it Gaussian poster child –Vector optimized Static IT models –Network defenders in IT hurt researchers –Researchers don’t play with others well –Condo model evolving

13. Versus Thinking this is just for science/engineer –Large data –Interactive applications Social Science apps –Education outcomes at Clemson Large data, statistics on huge scale –Shoah Foundation at USC Massive data, networks, VO

14. Vision/Sales Pitch Access to various kinds of resources –Parallel high performance Can be in condo (depends on politics) –Flexible node configurations –Large storage of various flavors –Viz –Leading edge networks

15. “Clusters” Large collection of multi-core –High performance interconnect What makes cluster not just a bunch of nodes –Access to large data storage at parallel speeds Lustre SAM/QFS PVFS –Ability to put in large memory nodes

16. “Clusters” –Magic chips GPUs, FPGAs etc Botique today but gains can be enormous –Relation to desktops/local systems –How to integrate into national systems Identity/security/networking –Viz clusters Render agents Large scale, friction free networking

17. Storage Farms Diverse data models –Large streams (easy to do) –Large number of small files (hard to do) –Integrate mandates (security, preservation) –Blur between institution data and personal/research –Storage spans external, campus, departmental,local –Speed of light matters

18. Meaning of Life Much closer relations needed to central IT –Networks/identity mgmt/security/policy –But not just ‘at scale’ How to use the disruptive technologies –Core,GPUs,Cell,FPGA,Flash,optical networks –Disruptive software/services as well

19. Meaning of Life Build ecosystem of services –Some central, some local, some external –Not just computing, networks and storage –Our community has “gone global” The campus is not a castle. Earlier example of 8 social science faculty We have thousands of communities Can’t be one size fits all
