The joint IEEE/ACM HPCA/CGO/PPoPP/CC 2026 conference took place in Sydney, Australia, from Saturday, 31 January to Wednesday, 4 February 2026, bringing together researchers from architecture, compilers, and parallel programming. Our Chair was represented by Prof. Anderson Faustino da Silva, Asif Ali Khan, and João Paulo C. de Lima, who contributed across several co-located venues. At CGO 2026, Anderson Faustino da Silva presented two papers in collaboration with Prof. Fernando Pereira: On the Precision of Dynamic Program Fingerprints Based on Performance Counters and Binary Diffing via Library Signatures. At HPCA 2026, João presented Count2Multiply: Reliable In-Memory High-Radix Counting, the result of a long-standing collaboration with Prof. Alex K. Jones. In addition, João gave an invited talk titled “Fault Injection Framework for Processing-using-Memory Architectures” at MCCSys 2026, the Workshop on Memory-Centric Computing Systems, and Asif presented “Compilation for Heterogeneous Near-Memory and In-Memory Computing Architectures” at LATHC 2026, the Workshop on Languages, Tools, and Compilers for Heterogeneous Computing.
