  - Supercomputing Frontiers and Innovations - Rok 2020

  Collaboration between multiple computing centres, referred as federated computing is becom- ing important pillar of High Performance Computing (HPC) and will be one of its key components in the future. To test technical possibilities of future collaboration using 100 Gb optic fiber link (Connection was 900 km in length with 9 ms RTT time) we prepared two scenarios of operation. In the first one, Interdisciplinary Centre for Mathematical...

  - Advances in Intelligent Systems and Computing - Rok 2020

  The paper presents an evaluation of all-reduce collective MPI algorithms for an environment based on a geographically-distributed compute cluster. The testbed was split into two sites: CI TASK in Gdansk University of Technology and ICM in University of Warsaw, located about 300 km from each other, both connected by a fast optical fiber Ethernet-based 100 Gbps network (900 km part of the PIONIER backbone). Each site hosted a set...

• Performance and Power-Aware Modeling of MPI Applications for Cluster Computing

  Publikacja

  • J. Proficz
  • P. Czarnul

  - Rok 2016

  The paper presents modeling of performance and power consumption when running parallel applications on modern cluster-based systems. The model includes basic so-called blocks representing either computations or communication. The latter includes both point-to-point and collective communication. Real measurements were performed using MPI applications and routines run on three different clusters with both Infiniband and Gigabit Ethernet...

• BC-MPI: running an mpi application on multiple clusters with beesycluster connectivity

  Publikacja

  • P. Czarnul

  - Rok 2007

  W artykule zaproponowano nowy pakiet BC-MPI, który umożliwiauruchomienie aplikacji MPI na wielu klastrach z różnymi implementacjami MPI. Wykorzystuje dedykowane implementacje MPIdo komunikacji wewnątrz klastrów oraz tryb MPI THREAD MULTIPLE dokomunikacji pomiędzy klastrami w dodatkowych wątkach aplikacji MPI. Ponadto, aplikacja BC-MPI może być automatycznie skompilowanai uruchomiona przez warstwę pośrednią BeesyCluster. BeesyClusterumożliwia...
