POSITION DESCRIPTION -Research Project / Research Group Description:

The computer architecture research group at INESC-ID has a long term research experience in high-performance computing (HPC) and computer architectures/systems, including the investigation of: novel microprocessor architectures; application-specific hardware modules (e.g., data management, application-specific co-processors, cryptographic functions); modeling embedded and high-performance computing devices (e.g., CPUs/GPUs); trusted computing solutions; parallel computing and load balancing; or exploitation of homogeneous and heterogeneous computing systems for application acceleration.

The research group is led by Leonel Sousa, a Full Professor at Instituto Superior Técnico (IST). Presently, he is also the head of both INESC-ID and the Department of Electrical and Computer Engineering of IST and a distinguished scientist of ACM. Leonel Sousa published around 300 articles in international journals and conferences and collaborated in the organization of multiple scientific venues. The research group features other researchers with significant contributions in computer architectures, such as Aleksandar Ilic, Nuno Roma, Pedro Tomás and Ricardo Chaves, professors at IST and researchers at INESC-ID, which have a combined track record of over 200 papers in journals and conferences, including in top-tier venues (e.g., HPCA, Micro, CHES, PACT, ISPASS, IEEE TPDS, IEEE TC, etc.).

The group has established important collaborations with industrial partners over the years (e.g., Intel, AMD, ARM, NVIDIA, Maxeller) and has contributed to many important research projects. Currently, these researchers collaborate in the European Processor Initiative (EPI), a European funded framework for the development of a new generation of low-power and extreme-scale computing devices, and lead or are partners in different research projects related to the development of post-quantum trusted platforms and of HPC systems for deep learning and bioinformatics applications.

-Job position description:

The research group is looking for a highly motivated PhD student with an excellent academic track record and good English skills to work in computer architectures and HPC systems. The PhD student will be enrolled in the Electrical and Computer Engineering PhD program at IST, and integrated into the current research activities and projects at INESC-ID, particularly in the investigation of new architectures and systems for HPC, bioinformatics and deep learning applications.

The rise of data collection and storage facilities have led to an explosion of the data that current systems must process. Because of this, application performance is often limited by the bandwidth and latency of the memory subsystem, constraining both processing throughput and energy-efficiency. Additionally, nowadays security requirements, force the development of trustworthy systems. The researchers of the computer architecture group are investigating solutions for these problems, at the following levels:

- Memory subsystem: New methodologies to overcome the memory bandwidth/latency limitations, including through non-conventional computing;

- Computer architecture: New techniques to improve the energy-efficiency of modern computing systems, e.g., through new micro-architectural approaches or power-saving techniques;

- Performance modeling: New approaches for performance, power, and energy-efficiency modeling of modern architectures (e.g., CPU/GPU), and its applications (e.g., DVFS);

- Applications: New parallel and HPC techniques for efficient execution and distribution of workloads across computing devices;

- Trust and Security: Novel computing structures and architectural solutions to provide trust and security in modern and/or non-conventional architectures.
