COMPSAC is the IEEE Computer Society Signature Conference on Computers, Software, and Applications. For almost 50 years, COMPSAC has been a central international forum for academia, industry, and government to present and discuss research results and advancements, emerging challenges, and future trends in computer hardware, software technologies, systems, and applications. The theme of COMPSAC 2023 is “Resilient Computing and Computing for Resilience in a Sustainable Cyber-Physical World.” The last few renditions of COMPSAC, which have been online because of COVID-19, have had profound consequences on our academic and industrial R&D communities. Yet these communities have shown resilience in the face of this adversity. Accordingly, we are introducing a new vision for both the theoretical and practical aspects of the fields of interest of our participating communities: resilient computing and computing for resilience. During the pandemic-induced chaos of the last few years, the world has mainly managed to resist chaos and maintain a sense of order and stability. This resistance has brought a new focus and meaning to our technology research direction, i.e., resiliency, availability, and sustainability. As we go forward, we have learned that we must carefully prepare a variety of alternatives, keep them in operation, and continue to adapt them and us to changing circumstances. For instance, the notion of security can be interpreted as the maintenance of high availability. It can also be said that resilience is the ability to keep the lights burning, even if the quality of stability is significantly reduced. Authors are invited to submit original, unpublished research work and industrial practice reports. Simultaneous submission to other publication venues is not permitted except as highlighted in the COMPSAC 2023 JC & CJ program. All submissions must adhere to IEEE Conference Publishing Policies and will be vetted through the IEEE CrossCheck portal.
