BioExcel workshop

BioExcel workshop on GROMACS and HADDOCK

  • Date: October 18 – 19, 2023
  • Venue: Faculty of Natural Sciences, Ilkovičova 6, Bratislava
  • Format: hybrid, but in-person attendance is recommended for better learning experience
  • Hands-on workshop
  • Participation free of charge

National Competence Centres for HPC in Slovakia, Austria, Czechia and Hungary, together with BioExcel – Centre of Excellence in HPC are organizing a 1,5-day workshop focused on GROMACS software package. Focus will be on basic usage and deployment on GPU-accelerated HPC systems, the agenda will also cover more of the core modules for GROMACS developed by BioExcel (Haddock or PMX).

The workshop will take place in Bratislava, which can be reached conveniently from all involved countries: Slovakia, Czechia, Austria and Hungary. Participants from the rest of the EuroCC network are welcome, too! The event is organized in hybrid format, however, in-person participation is strongly encouraged. Attending in-person will allow you to get the most of the workshop, to interact closely with the lecturers during the lectures and practical exercises – simply to learn more!

BioExcel is the leading European Centre of Excellence for Computational Biomolecular Research. It is a major research and innovation hub for scientific computing, developing some of the most popular applications for modelling and simulations of biomolecular systems. BioExcel was established in 2015 and is now supported by the Horizon Europe programme.

Its mission is to accelerate the development and usability of the most widely used European open-source software for computational biomolecular research: GROMACS for molecular dynamics simulations; HADDOCK for integrative docking; PMX for free energy calculation preparation, and ensure that this continues to achieve significant impact in the international HPC landscape. These applications can be used with a range of pre-/post-processing tools within user-friendly workflows and container solutions. The software stack comes with great performance and scalability capabilities for extreme-scale utilization of the worlds largest high-performance computing (HPC) and high-throughput computing (HTC) compute resources.

BioExcel collaborates closely with the European High Performance Computing Joint Undertaking (EuroHPC JU) and participating member states – and the network of the National Competence Centres for HPC.


GROMACS is one of the major software packages for the simulation of biological macromolecules. It is aimed at performing the simulation of large, biologically relevant systems, with a focus on both being efficient and flexible to allow the research of a number of different systems.

It is also one of the most widely used scientific software packages in the world, it is the largest free software and open source application in biomolecular research, and the only one of the major molecular dynamics simulation packages where development is led in Europe. GROMACS can use thousands of cores and hundreds of accelerators efficiently in parallel, enabling researchers to study large and complex biomolecular systems using supercomputing infrastructures.

HADDOCK is a versatile information-driven flexible docking approach for the modelling of biomolecular complexes. HADDOCK distinguishes itself from ab-initio docking methods in the fact that it can integrate information derived from biochemical, biophysical or bioinformatics methods to enhance sampling, scoring, or both. HADDOCK supports the incorporation of data from NMR and other biophysical methods, e.g. MS cross-linking and mutagenesis data, to drive the modelling process and the use of SAXS and IM-MS data to filter docking solutions.

How to get to Bratislava

BY PLANE: Bratislava Airport (BTS)

There are direct flights to a number of destinations in Europe and a number of airlines operate their direct routes to Bratislava. Bratislava airport can be reached from the city centre in 15–20 minutes. To get to the city center you can take a taxi – do not forget to ask about the price in advance or use HOPIN mobile app. If you travel on the budget,  take the bus no. 61 to the main train station. From here, you can walk to the city centre in 15 minutes or take bus no 93 (exit Hodžovo námestie) or tram no 1 (exit Námestie SNP). Bus tickets are available from ticket machines at bus stops or in kiosks. The tickets which cost around EUR 1 must be validated in the buses.

BY PLANE: Vienna – Schwechat Airport (VIE)

The airport at Vienna-Schwechat is only 40 kilometres west of Bratislava and it is one of the main gateways to Slovakia. Buses to Bratislava depart at 30 to 60-minute intervals. Tickets can be bought on the bus; chceck the following companies,,

BY TRAIN: ZSSK – Slovak National Carrier

Bratislava connects to the main lines from Prague, Budapest, Vienna and various regions in Slovakia. The Bratislava Main Station is well connected to the rest of the city via trams, buses or trolleybuses and you can get to the Old Town on foot in only 15 minutes. From the train station in Petržalka, the no. 80, 91, 93 buses take you to the city centre.

BY TRAIN: RegioJet

Bratislava is also conveniently connected with many European cities via a network of bus lines. It has frequent service to the surrounding areas and also to other regions in Slovakia. Buses arrive and depart from Mlynské Nivy bus station. Coaches between Bratislava and Vienna run at one-hour intervals.

Useful links:



Bratislava is situated at the intersection of several important motorways. The distance to Prague is 330 km, Budapest 200 km and Vienna 65 km. If you are bringing your own car, you need to have a valid electronic vignette to use the specified sections of motorways and expressways. The vignette is related to a specific time period regardless of the distance driven or the number of journeys. The minimum validity period is ten days (costs around EUR 10). HERE.
