Abstract
Subproject C1 investigates operating-system support for invasive applications. It provides methods, principles and abstractions for the application-aware extension, configuration and adaptation of invasive computing systems. These are technically integrated into the invasive Run-time Support System (iRTSS), a highly scalable native operating system in close contact and constant touch with a standard Unix-like host operating system. The project addresses special-purpose MPSoC-based as well as general-purpose multi/manycore machines.
In the first funding phase, the core areas of research were (1) new design approaches for low-latency operating systems, (2) new methods based on aspect-oriented programming (AOP) for their static and dynamic (re-)configuration and (3) agent-based strategies for the highly scalable management of their resources. Outcome was (1) OctoPOS, a hardware-centric and lock-free parallel operating system of event-based kernel architecture, (2) an aspect-oriented generator for hardware-tailored cross-tile RPCs and (3) a protocol machine for application-centric bargaining of resource allocations.
In the second funding phase, the core areas of research were (1) on-demand partial virtualisation of selected computing resources, namely address-space claims, and devirtualisation of those claims when the need for virtuality ceased to exist, (2) dynamic reconfiguration of iRTSS, and (3) agent-based strategic control according to self-adaptivity and decentralised resource management. Outcome was (1) an "elastic OctoPOS" that provides for the "invasion of its own dominion" in a controlled manner, (2) a system-software "variant generator" that produces non-functionally different incarnations of selected OctoPOS functions, (3) referring to this, a run-time executive to dynamically switch between the variants, and (4) an enhanced Agent System providing responsive and robust resource management that scales with the respective problem size.
In the third funding phase, the general focus will be on the enforcement of required quality criteria of mixed criticality as to timing and energy consumption by means of application-oriented resource allocation strategies as well as mechanisms at iRTSS level. This includes a worst-case execution time (WCET) analysis for the Agent System to identify the performance corridors of resource allocation for given use cases. Emphasis is also on the control of background noise (i.e., indirect overhead) of OctoPOS functions that provide transparent access (virtual shared memory, VSM) to the different main-memory subsystems of the PGAS (partitioned global address space) model as defined for invasive computing. Measured overheads as to timing and energy consumption are externalised as system parameters (i.e., non-functional properties) in order to be able to give a precise prognosis on the effectiveness of a particular i-let schedule. The investigations target small-, medium-, and large-scale multicore systems of different processor and memory architecture to obtain a broad parameter set for real machines suitable for the execution of invasive programs. In this regard, already existing and still proposed fundamental concepts, abstractions, and techniques of invasive computing will be brought to the domain of state-of-the-art manycore systems in order to prove general applicability and field performance of the solutions created. Our intention is to reap the achievements of invasive computing to the advantage of general-purpose systems.
Synopsis
Research focus of Subproject C1 in the third funding phase is the enforcement of quality criteria of mixed criticality as to timing and energy consumption by means of application-oriented resource allocation strategies as well as mechanisms at iRTSS level. Beyond that, already existing and still proposed fundamental concepts, abstractions, and techniques of invasive computing will be brought to the domain of state-of-the-art manycore systems in order to prove general applicability and field performance of the solutions created. The major work packages include (1) enforcement of Agent System (AS) properties (currently no guarantees may be given on execution time bounds for claim determination and quality of returned claims), (2) hardening the AS against malicious re-invaders, (3) energy-efficient process coordination and virtual shared memory, and (4) control of background noise as to OctoPOS functions that provide transparent access to the different main-memory subsystems of the PGAS model as defined for invasive computing. Measured overheads as to timing and energy consumption are externalised as system parameters (i.e., non-functional properties) in order to be able to give a precise prognosis on the effectiveness of a particular i-let schedule. The investigations target small-, medium-, and large-scale multicore systems of different processor and memory architecture to obtain a broad parameter set for real machines suitable for the execution of invasive programs.
Approach
The research question of the current application emanates from the achievements of the second funding phase and the existing knowledge on (a) predictable and robust resource-allocation measures, (b) energy-efficient computer operations, and (c) low-latency operating-system features for enforcement purposes as to the functional and non-functional properties stated by an invasive application. Our basic assumption is that "property enforcement" calls for a "cooperative operating system" in order to facilitate bidirectional smooth user-/system-level transitions in the course of processing work assignments. Based on this, the special implication that a highly interactive operating-system structure has on the (predicted) performance in terms of lead time and energy consumption of invasive-parallel processes is scrutinised. We also question the general implications that this approach has for the operation of commodity manycore multiprocessor systems.
Detailed Description: OctoPOS
The system software OctoPOS acts as a broker between the X10 runtime system
with its applications and the underlying hardware.
Interaction with the X10 runtime system
The OctoPOS provides an interface for mapping the different activities inside an X10 programm onto the different flavours of invasive hardware. Depending on the actual hardware configuration, this process can be partially supported dedicated hardware, for instance by the Dynamic Many-Core i-let Controller (CiC). Moreover the OctoPOS implements facilities for intra-tile, cross-tile and cross-application communication using shared memory, where available, or the invasive NoC (iNoC).
Interaction with the underlying hardware
Among the supported hardware platforms are SPARC Leon, i-Core and Intel x86. In addition, it is possible to run OctoPOS as a user process within a Linux system, enabling developers to test applications with the entire invasive software stack.
