Seventh Workshop on Models, Algorithms and Methodologies

for Hybrid Parallelism in new HPC Systems (MAMHYP-24)

Ostrava, Czech Republic, September 8-11, 2024

jointly with the

15th International Conference on Parallel Processing

and Applied Mathematics PPAM 2022

(https://ppam.edu.pl/)

Background

MAMHYP-24 is the seventh workshop following those held in Torun, Warsaw, Krakow, Lublin, Bialystok and Gdansk in 2011, 2013, 2015, 2017, 2019 and 2022, respectively, in conjunction with the PPAM conferences. Despite the progress made in the field, developing efficient algorithms for HPC systems with multiple forms of parallelism remains a challenging problem.

More precisely, from an architectural perspective, a High-Performance Computing (HPC) system can be characterized by a hybrid multi-level structure: at the highest level, several systems are interconnected by geographic networks (System level); an intermediate level consists of nodes within a single system communicating through dedicated fast networks or high-performance switches (Node level); finally, at the lowest level, there are multiple computing elements, including computing cores and graphic accelerators, sharing resources within a single CPU (Core level).

These architectural levels exhibit distinct features, necessitating different algorithmic development methodologies. Consequently, the development of algorithms and scientific software for these systems requires a judicious combination of methodologies to address the diverse forms of parallelism corresponding to each architectural level. The overarching objective is to develop hybrid and hierarchical algorithms capable of leveraging the underlying platform. Key challenges in this domain include managing extensive degrees of parallelism stemming from numerous computing units, addressing the heterogeneity of these devices, and integrating various forms of parallelism into a single algorithm. These issues are primarily investigated to achieve exascale performance and, on another front, to confront new forms of distributed computing such as cloud computing, edge computing, and their intersection with HPC.

This workshop specifically targets Models, Methodologies, Algorithms, and Environments for harnessing all forms of parallelism and their amalgamation at all levels within emerging HPC systems, aiming to consolidate the current state of knowledge in the field.

The topics include, but are not limited, to:

Hybrid and hierarchical based parallel algorithms
Multi-core and many-core parallel computing, GPU computing
Architecture-aware parallelization on HPC platforms
Auto tuning techniques for heterogeneous and parallel environments
Performance analysis
Techniques for multi-/many-core platforms, NUMA architectures, or accelerator components
Task scheduling and load balancing among computing elements
Synchronization and access to shared resources
Multilevel cache management
Computational kernels for scientific computing and applications
Performance and scalability models
Tools and programming environments supporting efficient usage of multilevel parallelism.
Resources virtualization
High Performance cloud/edge/fog computing
Intra/Infra Virtual machines high performance communications algorithms
Fault tolerant implementation
