HARPA-Harnessing Performance Variability

HARPA-Harnessing Performance Variability

Duration: 39 months (2013 - 2016)

Start:1/9/2013

Project Website:http://www.harpa-project.eu/

Principal Investigator: Γιαννάκης Σαζεϊδης

Main Funding Source: EU-FP7 COOPERATION

Total Cost: 506 488

The overall goal of our project is to provide architectures (both Embedded Systems (ES) and High Performance Computing (HPC)-oriented) with efficient mechanisms to offer performance dependability guarantees in the presence of unreliable time-dependent variations and aging throughout the lifetime of the system. This will be done by utilizing both proactive (in the absence of hard failures) and reactive (in the presence of hard failures) techniques.

The term "performance dependability guarantee" refers to time-criticality in ES (i.e., meeting deadlines), and a predefined bound on the performance deviation from the nominal specifications in the case of HPC. The promise is to achieve this reliability guarantee in both domains with a reasonable energy overhead (e.g. less than 10% average). A significant improvement is hence achieved compared to the SotA, which now provides guarantees at the payoff of at least 50% overhead. In addition, we will provide a better flexibility in the platform design while still achieving power savings of at least 20%. To the best of our knowledge, this is the first project to attempt a holistic approach of providing dependable performance guarantees on both ES and HPC systems. This is done while taking into account various non-functional factors, such as timing, reliability, power, and ageing effects.

The HARPA project aims to address several scientific challenges in this direction:

1.Shaving margins. Similar to the circuit technique Razor, but with different techniques at the microarchitecture and middleware, our aim is to introduce margin shaving concepts into aspects of a system that are typically over-provisioned for the worst case.

2.A more predictable system with real-time guarantees, where needed.The different monitors, knobs, and the HARPA engine will make the target system more predictable and proactively act on performance variability prior to hard failures.

3.Implementation of effective platform monitors and knobs. HARPA will select the appropriate monitors and knobs and their correct implementation to reduce efficiency and performance overheads.

Welcome

Welcome to the website of the Department of Computer Science at the University of Cyprus. The Department has experienced significant growth over the last few years with strong groups in artificial intelligence, computer architecture, computer networks, data management, graphics and virtual reality, internet computing, software engineering and theoretical computer science. The Department offers a Bachelor degree in Computer Science with 7 different specializations as well as a number of Master degrees and a Ph.D. degree in Computer Science.

The Department has a strong research infrastructure comprising high-performance clusters and storage area networks, cloud computing facilities, smart-phones and sensing devices and virtual reality equipment. Since 2005, our Department has been involved in more than 160 research projects funded from both the European Union and the Cyprus Research Promotion Foundation with total funding of over 21.5 million euros.
