Poznan, Poland. May 31, 2017. ADVA Optical Networking today announced that the Poznan Supercomputing and Networking Center (PSNC) has deployed its FSP 3000 CloudConnect(TM) with QuadFlex(TM) 400Gbit/s technology in PSNC's PIONIER network. The data center interconnect (DCI) solution with its unique openness and scale is now transmitting enormous data loads using the 16QAM modulation format. The 96-channel network, which connects supercomputing centers in Poznan and Warsaw, removes data restrictions and enables researchers to share huge data sets. It will empower Poland's research and education community to collaborate, distribute findings and access data-intensive applications on an unprecedented scale. The network was installed and will be maintained by the Polish systems integrator and ADVA Optical Networking partner, Alma SA. "This new solution is our response to soaring demand from Poland's research and education community. Access to high-capacity applications and ultra-fast data transport has become essential for universities and research institutes. The ADVA FSP 3000 CloudConnect(TM) enables us to answer that fierce demand. It delivers the enormous capacity that the scientific community increasingly relies on while optimizing space and power consumption," said Maciej Stroinski, technical director, PSNC. "The giant leap in capacity opens up so many more possibilities. We can now provide almost unlimited access to our world-class IT resources, facilitating computational-based research into everything from climate modeling to space exploration. What's more, we now have the power to seamlessly scale our network to accommodate the needs of tomorrow." Built on the ADVA FSP 3000 CloudConnect(TM), the new infrastructure utilizes the company's QuadFlex(TM) technology to transport 400Gbit/s over 385km without the need for signal regeneration. To achieve this channel capacity, it is configured with two 200Gbit/s wavelengths operating at 16QAM within an optical super-channel. Designed for scalability and bandwidth optimization, the ADVA FSP 3000 CloudConnect(TM) platform offers unrivalled efficiency. It delivers huge energy savings and, with its incredibly small footprint, consumes less rack space than competing technology. The ultra-high-capacity link is a key section of the PIONIER network, which is operated domestically by PSNC. PIONIER is a consortium of Polish research and education organizations, including universities, scientific institutions and super-computing centers. "Our FSP 3000 CloudConnect(TM) solution is ideal for delivering 400Gbit/s bandwidth in research and education networks.

We investigate streaming instability using two-fluid approximation (neutral gas and dust) in a quasi-global, unstratified protoplanetary disc, with the help of PIERNIK code. We compare amplification rate of the eigenmode in numerical simulations, with the corresponding growth resulting from the linear stability analysis of full system of Euler's equation including aerodynamic drag. Following Youdin & Goodman (2005), we show that (1) rapid dust clumping occurs due to the difference in azimuthal velocities of gas and dust, coupled by the drag force, (2) initial density perturbations are amplified by several orders of magnitude. We demonstrate that the multifluid extension of the simple and efficient Relaxing TVD scheme, implemented in PIERNIK, leads to results, which are compatible with those obtained with other methods. ©2013 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.

Journal of Scheduling | Year: 2010

In this paper, we propose a new method for multiuser, multicriteria job scheduling in Grid environments with QoS guarantees concerning time and cost. The main goal of our method is to find a fair schedule of jobs that were submitted by multiple users. To obtain a schedule which is satisfactory for each user we aim at finding a set of advance reservations (ARs) for multiple users at once. This goal is achieved by adequate use of the Ordered Weighted Averaging (OWA) operator and Multiobjective Evolutionary Algorithm (MOEA) with carefully designed problem representation and operators. We also propose a data structure and algorithm used to manage and search for resource availability time slots. Efficiency and usefulness of our approach was demonstrated by computational experiments conducted within a simulation environment. © Springer Science+Business Media, LLC 2010.

We propose a quantum solution to the classical private information retrieval (PIR) problem, which allows one to query a database in a private manner. The protocol offers privacy thresholds and allows the user to obtain information from a database in a way that offers the potential adversary, in this model the database owner, no possibility of deterministically establishing the query contents. This protocol may also be viewed as a solution to the symmetrically private information retrieval problem in that it can offer database security (inability for a querying user to steal its contents). Compared to classical solutions, the protocol offers substantial improvement in terms of communication complexity. In comparison with the recent quantum private queries protocol, it is more efficient in terms of communication complexity and the number of rounds, while offering a clear privacy parameter. We discuss the security of the protocol and analyze its strengths and conclude that using this technique makes it challenging to obtain the unconditional (in the information-theoretic sense) privacy degree; nevertheless, in addition to being simple, the protocol still offers a privacy level. The oracle used in the protocol is inspired both by the classical computational PIR solutions as well as the Deutsch-Jozsa oracle. © 2011 American Physical Society.

The keynote will address various ICT aspects related to future platforms, applications and services that may impact and hopefully improve the way various business and enterprise processes will be organized in the future. New development tools, easy-to-program powerful mobile devices, interactive panels, etc. enable users to prototype new IT systems with much better interfaces, to quickly setup collaborative environments and easily deploy online applications. However, many people have not realized how quickly data, computational and networking requirements of these new information systems have increased and what constraints are behind existing underlying e-Infrastructures. Therefore, the main aim of this keynote will be to share with the audience example scenarios and lessons learned. Additionally, various challenges encountered in practice for future information systems and software development methods will be briefly discussed. The keynote will be summarized by an updated report on existing research e-Infrastructures in Poland and worldwide. © 2012 Springer-Verlag Berlin Heidelberg.

The focus of this paper is a Data Center Workload and Resource Management Simulator (DCworms) which enables modeling and simulation of data centers to estimate their performance, energy consumption, and energy-efficiency metrics for diverse workloads and management policies. We present its functionality in terms of energy-efficiency modeling and methods of power usage estimations available in the simulator. Moreover, we show an application of DCworms within the CoolEmAll project that addresses the important problem of data center energy efficiency. © 2013 Springer-Verlag.

We present simulations of the magnetized interstellar medium (ISM) in models of massive star-forming (40 M⊙ yr-1) disk galaxies with high gas surface densities (Σgas ∼ 100 M ⊙ pc-2) similar to observed star-forming high-redshift disks. We assume that type II supernovae deposit 10% of their energy into the ISM as cosmic rays (CRs) and neglect the additional deposition of thermal energy or momentum. With a typical Galactic diffusion coefficient for CRs (3 × 1028 cm2 s-1), we demonstrate that this process alone can trigger the local formation of a strong low-density galactic wind maintaining vertically open field lines. Driven by the additional pressure gradient of the relativistic fluid, the wind speed can exceed 10 3 km s-1, much higher than the escape velocity of the galaxy. The global mass loading, i.e., the ratio of the gas mass leaving the galactic disk in a wind to the star formation rate, becomes of order unity once the system has settled into an equilibrium. We conclude that relativistic particles accelerated in supernova remnants alone provide a natural and efficient mechanism to trigger winds similar to observed mass-loaded galactic winds in high-redshift galaxies. These winds also help in explaining the low efficiencies for the conversion of gas into stars in galaxies, as well as the early enrichment of the intergalactic medium with metals. This mechanism may be at least of similar importance to the traditionally considered momentum feedback from massive stars and thermal and kinetic feedback from supernova explosions. © 2013.
