For the last few years, Aleksandar Ilic focused his research on the field of computer architectures, namely modern multi-core embedded/general-purpose processors (CPUs) and programmable accelerators, such as graphics processing units (GPUs). He is an Associate Professor with the Department of Electrical and Computer Engineering (DEEC) of Instituto Superior Técnico (IST), Universidade de Lisboa and he is currently developing his research work at INESC-ID Lisboa (Instituto de Engenharia de Sistemas e Computadores Investigação e Desenvolvimento em Lisboa), Portugal. During the PhD, his research activities were mainly focused on investigating efficient strategies for task scheduling, dynamic load balancing, and runtime performance modeling in heterogeneous computing systems. This work considers not only single-node systems that combine devices of different architectures, but also multi-node clusters equipped with multi-core CPUs and several GPUs. For this, several applications from different scientific domains were considered, such as bioinformatics, video encoding, digital signal processing, linear algebra, and database applications. Aleksandar Ilic's research is also dedicated to designing and modeling of modern CPU architectures. More specifically, his research interests are focused on insightful modeling of modern multi-core architectures with complex memory hierarchies for performance, power consumption and energy-efficiency. As evidence of the impact of Aleksandar's research, in 2017, Intel Corporation fully integrated one of his research contributions (namely, the Cache-Aware Roofline Model) into their proprietary Intel Advisor tool, which is aimed at helping the end-costumers when analyzing and optimizing the execution of their applications. For this achievement, he received the HiPEAC Tech Transfer award in 2017. Furthermore, different approaches for the optimization and characterization of real-world applications are investigated, as well as novel scheduling strategies for efficient utilization of system and device resources. Based on these efforts, after finishing the PhD, Aleksandar Ilic has extended his main research lines to also include energy-aware task scheduling for modern heterogeneous embedded systems, tools for accurate application characterization and amending scheduling decisions at the operating system (OS) level, as well as automatic tuning of multiple data-parallel kernels for performance and energy-efficiency. In addition to the collaborative research with different INESC-ID scientific groups and action lines, Aleksandar is also involved in several international research and industry collaborations, such as with Intel Corporation (France and USA), AMD (US), Imagination Technologies/MIPS (UK), INRIA Bordeaux Sud-Ouest (France), Technische Universitat Berlin (Germany), University of Extremadura (Spain) etc. His research interests include high performance, power- and energy-efficient computing and micro-architectures for general purpose, embedded and specialized processors. In detail, his current research interests are aimed at developing efficient task scheduling and load balancing techniques for highly heterogeneous computing systems that combine different multi-core CPUs, GPUs and FPGA devices. Moreover, he is currently investigating efficient modeling, scheduling and monitoring approaches based on hardware monitoring events for different device architectures. -Program committee member several international conferences and workshops (including Cluster, Euro-Par, PPAM, HPCS, HeteroPar, SBAC-PAD,...); -Reviewer for research projects (Netherlands and Austrian Science Fund - FWF) and international conferences and journals (including IEEE TPDS, IEEE TComp, PARCO, PACT, ICS, IPDPS...); - Participation in the organization of EuroPar21, Cryptacus¿18 and ISPDC¿09 and several COST meetings and actions (IC0804/05); - Affiliate member of HiPEAC European Network of Excellence
