| After obtaining my Ph.D. degree in 1998, and with over six years of experience as an Instructor and Assistant Professor in Argentina, Gabriel A. Wainer joined Carleton University in July of 2000 as Assistant Professor. He got Tenured in July 2004, and promoted to the rank of Associate Professor in July 2005 and Full Professor in July 2012. | After obtaining his Ph.D. degree in 1998, and with over six years of experience as an Instructor and Assistant Professor in Argentina, Gabriel A.

| | Prof. Wainer started his research career in the field of Real-Time (RT) Operating Systems (OS) and RT scheduling in 1993 at the University of Buenos Aires, Argentina. With limited resources and self-supervised, his research focused on scheduling algorithms and services implemented in the first open-source version of an RTOS (called RT-Minix). These results were published in 16 research papers and a book. Shortly after, these ideas were followed by other researchers, leading to the development of the initial versions of RT-Linux (the first RTOS kernels used and cited our work, which was unique in 1993 when Linux and open-source software were still in their infancy). RT Linux kernels evolved, and work derived from his original research were included in Wind River Systems RTOS. His approach continues to be used and cited, and there have been Real-Time Minix projects based on the concepts Prof. Wainer invented in the '90s until 2020 (e.g. [Mancina, A., Tanenbaum, A.S. et al (2009). Real-Time Systems, 43, 177-210] [L. Kumar K.J, (2019). doi.org:10.47164/ijngc.v10i3.163]). |

| His research at Carleton focuses on techniques for transforming simulation models into real-time systems. The long-term goal is to reduce to a minimum the manual development of real-time software (a time consuming, error prone and expensive task), and the interfacing of these models with simulation software. These efforts have received support in approximately 1.5M$ from different funding agencies (NSERC, Precarn, CFI, OIT, CANARIE) and companies (IBM, HP, CMC, MDA, Intel). As a Co-PI Prof. Wainer participated in numerous research projects (with funding totaling over 30M$, from which approximately $1.1M have been directly spent for his research). His students have always been successful in applying to numerous scholarships and awards, and they have obtained funding for their research in excess of 500K$. | Since 1996, he contributed to the field of Modeling and Simulation (M&S), introducing Cell-DEVS, a formalism that reduces the complexity of the development of models of physical systems while increasing the speed of their simulations. Prof. Wainer also defined new high-level languages and their mapping into DEVS (a formal Discrete-Event Specification formalism) and Cell-DEVS. This includes the ATLAS traffic language, Petri Nets (timed, colored), Layered Queuing Networks, Timed Automata, Finite State Machines, Bond Graphs; and even a generic environment based on Modelica. This approach allows defining formal models that are discrete-event, spatial, continuous or hybrid, and can be easily combined and reused. Cell-DEVS has been included in different tools. We defined and implemented our own open-source tool, CD++/Cadmium. Cell-DEVS was extended by his students to define other spatial including Centroidal Particle Dynamics and the Tethered Particle System, which allow to define complex particle-based spatial models. CD++/Cadmium has been used to develop models in different domains: epidemiology, ecosystems, 5G wireless networks, resiliency, social interaction, pedestrian flow, architectural design, etc. The software has been used in universities for teaching and research, and in research projects with industry and government agencies (NRC, NRCan, Autodesk, Ericsson, Bentall Kennedy, and others). |
| |
| The results of his research are reflected in numerous publications: | Prof. Wainer and his team defined varied algorithms to run these DEVS and Cell-DEVS models in multiprocessor and distributed architectures using varied middleware). The simulation engines now provide the means to run distributed simulations using Web-Services, Cloud and Fog middleware as well as parallel algorithms with high performance. Users can develop and test models in local workstations, submit them to a remote parallel simulator, receive, visualize, and analyze the results locally (using advanced visualization tools). Using distributed coordination algorithms, a model can be split and be simulated remotely in distributed fashion. We defined and built RISE, the first distributed simulation middleware built on RESTful Web Services. |

| In most of these papers, he has been the main author (or a co-author with his students, who co-authored many of these articles). He has published a number of papers in the Simulation, Practice and Experience (Elsevier), and in the Transactions of the Society for Modelling and Simulation (SCS). As Modeling and Simulation is a multidisciplinary field, he has published also in other areas: Transactions of Computational Systems Biology, Molecular Simulation, Mobile Networks and Applications; Software, Practice and Experience; Parallel Processing Letters, and Automation in Construction. His research contributions have received numerous citations (over 1,000, a large number in this research domain; he as been cited as Top-3 ranked Author in the field of Simulation -Last 10 years- by the Microsoft Academic Research site; February 1, 2011). | He introduced the DEVStone synthetic benchmark and related tools, which became a de-facto standard to evaluate DEVS simulators and compare their performance from 2005 to this day. DEVStone provides a non-arbitrary method to evaluate the performance of discrete-event simulators by providing model sets with different characteristics, enabling the analysis of specific issues of simulation engines. DEVStone provides a synthetic mechanism for specifying objective ratings for DEVS-based simulators. DEVStone has been implemented in different DEVS tools by software designers to compare the quality of their simulation engines. |

| He has published and presented papers at some of the most prestigious conferences in Simulation worldwide. These include PADS, IEEE DS-RT, Winter Simulation Conference, the Annual Simulation Symposium and SPECTS. He has various publications in the Symposium on Theory of Modeling and Simulation (TMS/DEVS) and various conferences sponsored by SCS. He has published in other areas, including IEEE Real-Time and Embedded Technology and Applications Symposium (Real-Time Systems); Simulation for Architecture and Urban Design, Intl. Conference on short and medium bridges (building simulation); High Performance Computing and Simulation, IEEE EMBS, CMBE (biomedical); AHDS (Analysis and Design of Hybrid Systems), International Conference of Web Services; Environmental Modeling and Software; International Conference in Compu-tational Science; Cellular Automata for Research and Industry (ACRI), and many others. | Prof. Wainer defined new methods based on modeling and simulation techniques to build RT model prototypes embedded in different platforms. The team defined and implemented a runtime executive integrating models with hardware surrogates (using Intel, ARM, Raspberry Pi and FPGA platforms). We also developed different versions running in multicore hardware, including prototype versions on Intel boards [J30]. We used these prototypes to define a bare hardware version of RT-DEVS models, which allows complete control of the models’ execution without interference of OS or middleware. |

| I discovered a strong vocation for teaching in the early years of my career. In 1989, being a Teaching Assistant at the Universidad de Buenos Aires (UBA) in Argentina, I started lecturing part-time in different institutions, where I had the chance to organize four different courses. Being a Head Teaching Assistant at the UBA, I organized an Operating Systems Laboratory course devoted to teach design and implementation of Operating Systems. The results of this course (including modifications and improvements to the kernel of an open-source operating system) were unique in Latin America (and one of the few worldwide, winning an international award in 1992). Later, as Instructor at the UBA, I organized new courses on Real-Time Systems, Discrete-Event Simulation and Real-Time Systems Implementation (students in these courses won awards in different contests). As Assistant Professor at the UBA, I completely reorganized the Computer Organization course with excellent results (student projects in this course were published in international conferences and in the ACM Journal of Educational Resources in Computing). | |
| |
| At Carleton, I have taught very challenging undergraduate courses with a very large enrollment (since my hiring in July 2000, a total of 1834 students in my courses). I usually have very high teaching evaluations (an average of 4.21 for my Undergraduate courses, and an average of 4.66/5 for my Graduate courses). I have a particular teaching philosophy, which focuses on extensive class discussion, thinking, analysis and interaction, which provides a better mechanism for understanding and concept retention. | He discovered a strong vocation for teaching in the early years of his career.

| I also had the opportunity to develop a completely new graduate course, which had not been offered before my appointment (SYSC-5104, Methodologies for Discrete-Event Modeling and Simulation). I was able to introduce my own fully developed material, and the students use in-house developed tools to study advanced Modeling and Simulation problems. The best projects in the course are usually improved after the end of the course, and many of them have been accepted for publication in international conferences. Eleven papers have been already published. Two of them obtained awards. | At Carleton, he taught very challenging undergraduate courses with a very large enrollment (since his hiring in July 2000, a total of 1834 students in his courses).

| I have always encouraged my students to go beyond standard expectations, and I try to persuade them to showcase their work. For instance, twelve of my undergraduate projects (4th year, coop) resulted in papers accepted for publication. Many of them participated in conferences presenting the results of their course work. A team participated in the IEEE Computer Society International Design Competition, and new teams will participate in Microsoft's ImagineCup 2012.

| Over my years spent at Carleton University, I have been called on to participate in many activities and have been assigned various administrative duties. I am currently the SCE Departmental Web Editor, and the Director of the Research Centre on Technology Innovation (RCTI). I have partici-pated in numerous committees, including Tenure and Promotion, Scientific Advisory (V-Sim), University Supervisory Approvals Committee, Carleton University IEEE Computer Society Student Branch counselor, and the SCS Student Chapter coordinator. I was also the Department representative on the board of the School of Computer Science, and a member of the Departmental reviewing committee for Endowment, NSERC and OGS Scholarships. | ====== Service ====== |
| In addition to the above mentioned duties, I have contributed in many other ways. For example, I have been part of the evaluation committees for numerous Engineering projects, Theses, and Ph.D. Comprehensive Examinations. I initiated the Embedded Systems Group and organized around 50 seminars since I arrived in 2000. | |

| Externally, I am servicing the academic community in different international initiatives. I am cur-rently the VP Publications of SCS (in charge of two journals, a newsletter and a magazine). I am the Special Issues Editor of the Transactions of the SCS (appointment renewed for two years), and a member of the Editorial Board of various journals. I have been a reviewer for various journals, and the organizer of numerous international conferences and workshops. In particular, I have been the chair of SummerSim twice (increasing the number of submissions in 100% in one year, and highly improving the quality of those submissions, reflected in an increase of the rejection rate in over 200% in one year). I was also a co-founder of new successful conferences: SimAUD (Simulation in Architecture and Urban Design), SimuTools, and the new Symposium of Theory of Modeling and Simulation (thes last two became some of the most successful events in the world; one devoted to simulation theory and the other to simulation tools. Both symposia receive around 100 papers every year, and after a thorough evaluation process only 30% of those get accepted for publication). | Over his years spent at Carleton University, he has been called on to participate in many activities and have been assigned various administrative duties.
