The stagnation of traditional transistor scaling has driven researchers to rethink fundamental computer architecture design principles, fueling the rise of heterogeneous architectures. These systems integrate diverse processors and evolving memory hierarchies to meet the performance demands of modern applications while balancing energy efficiency and cost-effectiveness. Fully unlocking the potential of heterogeneity in computing requires a cross-layer approach, spanning hardware, runtimes, compilers, and applications, to advance next-generation computing systems.
This special issue serves as a platform for researchers to share theoretical insights, practical advancements, novel methodologies, and future directions in heterogeneous computing. Topics of interest include performance optimization, energy efficiency, programmability, and hardware-software co-design across heterogeneous platforms, ranging from High-Performance Computing (HPC) to real-time embedded systems.
While this special issue builds upon discussions from the Thirty-Fourth Heterogeneity in Computing Workshop, we welcome contributions from all researchers working on relevant topics and encourage participation from the broader community.
