“…Similar to Unicore service orchestrator [40], Stroll carries out task submission from the server, the case in which the load on the server is directly proportional to the number and size of submissions. We submitted 10 matrix-multiplication batch tasks from the LAN through the shared Stroll network drive.…”

Abstract. Developing applications for solving compute intensive problems is not trivial. Despite availability of a range of Grid computing platforms, domain specialists and scientists only rarely take advantage of these computing facilities. One reason for this is the complexity of Grid computing, and the need to learn a new programming environment to interact with the Grid. Typically, only a few programming languages are supported, and often scientists use special-purpose languages that are not supported by most Grid platforms. Moreover, users cannot easily deploy their compute tasks to multiple Grid platforms without rewriting their program to use different task submission interfaces.In this paper we present Stroll, a universal filesystem-based interface for seamless task submission to one or more Grid facilities. Users interact with the Grid through simple read and write filesystem commands. Stroll allows all categories of users to submit and manage compute tasks both manually, and from within their programs, which may be written in any language. Stroll has been implemented on Windows and Linux, and we demonstrate that we can submit the same compute tasks to both Condor and Unicore clusters. Our evaluation shows the overhead of Stroll to negligible. Comparing the code complexity of a Stroll compute task with command-line clients and Grid APIs show that Stroll can eliminated up to 95% of the complexity.

“…The two layered design with a separation of the workflow engine and the service orchestrator was primarily done for better scalability, but also offers the possibility to plug-in domain-specific workflow languages and workflow engines. The workflow engine originates from the EU-project Chemomentum [5]. Besides simple job-chains, while-and for-loops, workflow variables and conditional execution are supported.…”

SUMMARYThe loss of inter-neuron communication is related to many neuronal diseases such as Alzheimer's dementia. The nicotinic acetylcholine receptor (nAChR) plays a crucial role in this process and is severely affected upon disease progression. Successful therapy approaches rely on modulation of response signals, initiated by the flux of ions through the receptor integrated ion channel at the post-synaptic membrane. We present here the comparison of two methods for calculating the energy barrier of nAChR mediated ion permeation, in terms of accuracy and performance. Detailed descriptions of archetypical Gromacs characteristics are given offering better insight into computational service providers to meet the needs of scientists.
