1. 1. Emerging Paradigms in the Convergence of Cloud and High-Performance Computing

   Författare :Daniel Araújo De Medeiros; Ivy Bo Peng; Stefano Markidis; Pawel Herman; Valeria Cardellini; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High-performance computing; Kubernetes; airflow; elastic scaling; MPI; S3; Datalogi; Computer Science;

   Sammanfattning : Traditional HPC scientific workloads are tightly coupled, while emerging scientific workflows exhibit even more complex patterns, consisting of multiple characteristically different stages that may be IO-intensive, compute-intensive, or memory-intensive. New high-performance computer systems are evolving to adapt to these new requirements and are motivated by the need for performance and efficiency in resource usage. LÄS MER

3. 2. Multithreaded PDE Solvers on Non-Uniform Memory Architectures

   Författare :Markus Nordén; Michael Thuné; Sverker Holmgren; Xing Cai; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PDE solver; high-performance; NUMA; UMA; OpenMP; MPI; data migration; data replication; thread scheduling; data affinity; Beräkningsvetenskap; Scientific Computing;

   Sammanfattning : A trend in parallel computer architecture is that systems with a large shared memory are becoming more and more popular. A shared memory system can be either a uniform memory architecture (UMA) or a cache coherent non-uniform memory architecture (cc-NUMA). LÄS MER

4. 3. Large-scale I/O Models for Traditional and Emerging HPC Workloads on Next-Generation HPC Storage Systems

   Författare :Wei Der Chien; Stefano Markidis; Erwin Laure; Artur Podobas; Philip Carns; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HPC; I O; Parallel I O; MPI; object storage; TensorFlow; Data-Centric; Artificial Intelligence; Machine Learning; Computer Science; Datalogi;

   Sammanfattning : The ability to create value from large-scale data is now an essential part of research and driving technological development everywhere from everyday technology to life-saving medical applications. In almost all scientific fields that require handling large-scale data, such as weather forecast, physics simulation, and computational biology, supercomputers (HPC systems) have emerged as an essential tool for implementing and solving problems.

   Sammanfattning : Methods for performing large-scale parallel Molecular Dynamics(MD) simulations are investigated. A perspective on the field of parallel MD simulations is given. Hardware and software aspects are characterized and the interplay between the two is briefly discussed. LÄS MER

7. 5. Multiple Parton Interactions in Deep Inelastic ep-scattering at HERA

   Författare :Sakar Osman; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Jet Calibration; H1; Jets; Mini-jets; MPI; Low-x; Multiple; Dijets; Parton Dynamics; HERA; Fysicumarkivet A:2008:Osman;

   Sammanfattning : The production of jets with low transverse momenta (mini-jets) in deep inelastic electron-proton scattering is studied. The analyses uses data taken with the H1 detector at HERA during the years 1999 to 2000. LÄS MER
