SUMMARY:CHESS Seminar: Time-Portable Programming the JAviator in Tipto
	e OS
DESCRIPTION: Seminar | January 13 | 4-5 p.m. | 540 Cory HallSpeaker/Pe
	rformer: Christoph Kirsch\, University of SalzburgSponsor: CHESSThe JA
	viator (Java Aviator) is a high-performance quadrotor model helicopter
	 that is built around a high-integrity frame\, which is horizontally a
	nd vertically symmetric\, and supports high payloads through light-wei
	ght materials and advanced brushless motors. The JAviator is 1.3m in d
	iameter\, weighs 2.2kg in total\, and generates a maximum lift of 5.4k
	g\, which translates into a theoretical maximum payload of 3.2kg. With
	out payload the maximum &64258\;ight time is around 40min. We have des
	igned and built the JAviator completely from scratch and use it as tes
	t platform for software projects such as Exotasks\, which we developed
	 in collaboration with IBM Research\, and Tiptoe\, which is our own pr
	ototypical real-time operating system. Exotasks are an alternative to 
	Java threads\, and enable time-portable programming of hard real-time 
	applications in Java\, hence the name JAviator. Time-portable programs
	 do not change their relevant real-time behavior across different hard
	ware platforms and software workloads. Tiptoe supports even stronger f
	orms of time portability than Exotasks\, in particular\, the execution
	 of software processes whose real-time behavior\, even including syste
	m-level aspects such as their I/O communication and memory management\
	, can be predicted and maintained per process\, independently of any o
	ther processes. The talk will give an overview of the JAviator&39\;s h
	ardware and flight performance\, and then focus on the latest developm
	ents in the Tiptoe kernel\, in particular\, its time-portable process 
	model\, scheduler design\, and memory management. This is joint work w
	ith S.S. Craciunas\, H. Payer\, H. Roeck\, A. Sokolova\, H. Stadler\, 
	and R. Trummer.Event Contact: 510-xxx-xxxx\n
