- Our paper Efficient Multi-Processor Scheduling in Increasingly Realistic Models has been accepted into SPAA 2024. It studies the problem of scheduling arbitrary (Hyper-)DAGs under parallel computer models that account for data movement costs over hierarchical memory architectures, considering both non-uniform memory access latencies as well as non-uniform memory throughputs. Our scheduling framework combines NUMA-aware heuristics with ILP formulations and ILP solvers, and finds schedules that achieve up to 2.5x lower cost compared to baselines. Even when limited to uniform memory latency and throughput, our framework achieves 24 to 44 percent smaller cost on average compared to baselines. This work will also be presented at IPDPS 2024 as a poster.
- The seminar Recent Trends in Graph Decomposition which took place at Dagstuhl (picture:), has published its report. It contains a summary of talks given during the seminar as well as several open problems, including considerations on (Hyper-)DAG scheduling (see also papers here or here) and Algebraic Programming-- as well as, of course, many other topics. A grand thank-you to the editors and organizers, George Karypis, Christian Schulz, and Darren Strash, for bringing together such an excellent seminar and to Dagstuhl for hosting us!
- Our work on spectral clustering using ALP/GraphBLAS received an IEEE HPEC '23 outstanding short paper award.
- Our paper on expanding Algebraic Programming with views, structures, and dense matrices was presented at ARRAY 2023 and published with the ACM. See algebraic-programming.github.io for the overarching vision behind ALP and for extensive user manuals, soon including the newly presented ALP/Dense.
