System Software Environments Breakout Report June 27, 2002

What is the scope of existing efforts? 1.Scalable Systems Software Center 2.FAST-OS “lightweight kernel” effort 3.Science Appliance effort 4.Systems Management research 5.Blue Gene

Anemic Areas of Existing Research What are the under funded critical research issues? 1.Security – protecting systems from compromise 2.Fault tolerance – being able to run through failure. Three steps: detection, notification, system recovery Linkage between projects and groups for FT chain. 3.Validation of result – how know that app got right ans. Given system runs through failure.

Potential Gaps in Research What are the gaps in MICS research portfolio related to peta-scale computing? 1.What happens after Linux? 2.OS that supports the programming model – if it is going to change from dist. mem. Message passing then… 3.Alternate to microkernel approach “Concrete” holds everything together but is really heavy. 4.Local address space vs more expansive address support 5.Experimental architecture research testbed Arose during PIM discussion Platforms for software development Not just the commodity clusters we work with today ES40 and PIM not addressed

Getting Help From Others What is needed most from the other four groups? 1.Runtime & Programming models – feedback to OS so it can reconfigure to optimize needs, PIM is entangled across Programming and OS. 2.Data & vizualization - Scalable I/O – leverage SDM ISIC and Program models Checkpoint/restart 100K nodes 3.Portability & Interoperability - ??? Discussion but no clear things we need to leverage 4.Performance – feedback to OS so it can correct bottlenecks while apps run.
