Research Projects and Collaborations
The ATML collaborates in national (BMBF), European and EuroHPC JU scientific and HPC support projects.
The Algorithm, Tools and Methods Lab "Application Optimization and User Service Tools" is responsible for the optimization and scaling of applications in terms of performance, efficiency and parallel I/O. We provide users with the knowledge and proper tools sets for their project management and their work on the Jülich HPC systems. We strongly interact with the Simulation and Data Laboratories and the Cross-sectional teams "Methods and Algorithms" and "Performance Analysis" as well as the department "High-Performance Computing Systems".
We are experienced in parallelisation libraries like MPI and OpenMP. We know about specialities of the local HPC systems and this makes it possible for us to guide the users in optimization strategies on the Jülich systems, e.g. for compiler and memory usage, task mapping, and I/O.
We collaborate with users in the need of on-demand support, but we also offer close long-term collaborations with user projects to optimize their applications on the Jülich HPC systems, e.g. to implement parallel I/O or a hybrid parallelisation.
We focus on assisting users to choose optimal parameters for their simulations, this leads to our interest in benchmarking:
With this work we also assist the system administrators in evaluating the system behaviour.
We emphasize on equipping users with knowledge for their usage of HPC systems:
Our research interest is the optimization of parallel I/O, this has led to the library SIONlib, which implements efficient parallel I/O of task-local data from massively parallel applications.
In addition, we have a strong interest in tool development with focus on application monitoring, optimization and benchmarking. We are currently working on the following projects:
Due to our benchmarking activities we also develop system benchmarks:
We further put emphasize on convenient access to our systems and are developing software for managing projects and user accounts:
