UNICORE (UNiform Interface to COmputing REsources) is a Grid middleware for accessing high-performance computing capabilities and storage resources in a secure and seamless fashion. In its current version (7.0), it offers web services using SOAP (Simple Object Access Protocol) in conjunction with a security stack based on the Security Assertions Ma...
In this paper we present grid services for the biomolecular community offered by the Polish National Grid (Polish NGI). This work is motivated by the fact that in many application areas including life sciences there is increasing demand for disk space and computer power to store and process data. Emerging technologies such as Next Generation Sequen...
ICM, one of the major Polish HPC resource providers, migrated to the Slurm batch system as the first site in the PL-Grid and WLCG grid infrastructures. This article describes the Slurm integration issues and the solutions developed. The integration was focused on several areas where grid middleware interacts with the batch scheduling system, additi...
This paper presents work done to prepare compute resource reservations in the PL-Grid Infrastructure. A compute resource reservation allows a user to allocate some fraction of resources for exclusive access, when reservation is prepared. That way the user is able to run his/her job without waiting for allocating resources in a batch system.
In the...
A dedicated web portal has been requested by user communities as an alternative interface
to UNICORE resources for a long time. Compared to the traditional end-user clients such
as the UNICORE Rich Client (URC) and UNICORE Command-line Client (UCC), a portal,
accessed by a standard web browser, promises several advantages which are to be discussed...
Remote visualization using mobile devices has been a challenge for distributed systems for a long time. Large datasets, usually distributed on different servers require high network bandwidth and significant computational power for effective, real time rendering. The problem is getting more complex when data are visualized in collaborative environm...
Continuous growth in data-oriented research activities makes an efficient handling of large amounts of data increasingly important. The scientific data are often distributed, heterogeneous and shared between various research communities. Thus not only an increase in data volumes but also in their complexity can be observed. All that together makes...
The aim of this paper is to present a system which was created to provide monitoring facilities for the UNICORE grid in the PL-Grid project. The monitoring system is based on the Nagios monitoring framework and consists of numerous plugins. To minimize overhead produced by the monitoring actions, detailed dependency graph was created. The system is...

... Together with automated and user-defined documentation in our e-labbook (based on Semantic Me-diaWiki [7]), the actual data from an experiment or a simulation (digital twin), is used for pre-and post-analysis workflows on a high performance computing (HPC) cluster. The access to our HPC cluster is provided by the Uniform Interface to Computing Resources (UNICORE) [8]. A combination of metadata-and data-repository is used for the publication of results and the registration in our publication database Rossendorf Bibliography System (Robis). ...

... These include federated computing [2], edge computing [3,4], quantum computing [5], quantum networking and the envisioned quantum internet [6][7][8], among others, all of which promise exciting new capabilities and broader access to number crunching, data processing, and data use. To generate computing results, federated computing [9] brings the computation to where the data resides, e.g., in a medical device memory for which patient privacy measures related to personally identifiable information (PII) and protected health information (PHI) may exclude the transfer of the data to computing resources [10]. Edge classical computing (ECC) brings processing power (e.g., in the form of an edge server) closer to where the data are generated, even possibly closely integrated with the very sensor acquiring the data. ...

... REST(Representational State Transfer) is emerging as an easier and more flexible alternative to SOAP and WSDL based Web Services [35]. RESTful web services make use of JavaScript Object Notation(JSON) [36] instead of XML for resource representations and exploit HTTP methods explicitly for the resource manipulation instead of defining their own [37]. The adoption of REST by mainstream Web 2.0 service providers, including Google,Yahoo and Facebook and large organizations like Wal-Mart, indicates its growing acceptance, but REST can not replace SOAP everywhere, it comes with its own set of issues. ...
... The UNICORE Portal [3] is a generic web interface to the UNICORE grid middleware [4], providing seamless and secure access to high-performance computing, file systems and other resources. User functions include job submission and management, storage access, data transfer and more. ...
