Flexible and secure access to computing clusters
(Wydawnictwa AGH, 2010) Meizner, Jan; Malawski, Maciej; Bubak, Marian
The investigation presented in this paper was prompted by the need to provide a manageable solution for secure access to computing clusters with a federated authentication framework. This requirement is especially important for scientists who need direct access to computing nodes in order to run their applications (e.g. chemical or medical simulations) with proprietary, open-source or custom-developed software packages. Our existing software, which enables non-Web clients to use Shibboleth-secured services, has been extended to provide direct SSH access to cluster nodes using the Linux Pluggable Authentication Modules mechanism. This allows Shibboleth users to run the required software on clusters. Validation and performance comparison with existing SSH authentication mechanisms confirm that the presented tools satisfy the stated requirements.

Propozycja usługi autobilansowania (UAB)
(Wydawnictwa AGH, 2021) Cetnarski, Ryszard; Penskyy, Serhiy; Wawrzyniak, Karol
Distributed energy is developing at a high pace and needs new legislative solutions that will support it, while at the same time not place a big financial burden on the rest of society. This article presents and describes a potential solution that aims to address these goals. Autobalancing service rewards and incentivizes certain behavior of participants that is desirable from the point of view of the network. The types of actions that are incentivized by auto- balancing service are described in detail in this article and are based on simultaneous occurrence of electricity demand and generation in a well defined area of distribution grid. Two independent types of elements of the autobalancing service are postulated: (i) balanc- ing of energy, and (ii) balancing of power. These two elements are responsible for different system functions. Autobalancing service is incentivizing service providers to invest in flexible energy resourc- es as well as operating them in such a manner that is most useful from the point of view of electrical grid. Simulations that took into account technical and economical aspects of operation of energy clusters were conducted. Results indicate that introduction of the autobalancing service would be a sufficient incentive for clusters to invest in energy storage and provide flexibility resources to the grid operator.

The conception of cluster support policy in the realities of the Polish economy
(2012) Kaźmierski, Jan
Over the years clusters have become a phenomenon of every economy. They should be treated as a vital mechanism that activates region development. Therefore, cluster-based policy gains an exceptional meaning. Selecting that model of policy, the problem of public aid and support instruments' appliance are crucial issues. Beside the aspects that were mentioned above, the author also discusses barriers and limitations which are connected with cluster-based policy. He also indicates the ways to overcome them. The conclusions and implications that are presented are for the most part the aftermath of the author's own empirical research on cluster development issues.
