Dear Sir or Madam, (We apologize if you receive multiple copies of this message) ============================================================ Recent Advances in Message Passing Interface. 20th European MPI Users' Group Meeting (EuroMPI 2013) EuroMPI 2013 is being held in cooperation with SIGHPC Madrid, Spain, September 15-18, 2013 www.eurompi2013.org BACKGROUND AND TOPICS ------------------------------- EuroMPI is the preeminent meeting for users, developers and researchers to interact and discuss new developments and applications of message-passing parallel computing, in particular in and related to the Message Passing Interface (MPI). The annual meeting has a long, rich tradition, and the 20th European MPI Users' Group Meeting will again be a lively forum for discussion of everything related to usage and implementation of MPI and other parallel programming interfaces. Traditionally, the meeting has focused on the efficient implementation of aspects of MPI, typically on high-performance computing platforms, benchmarking and tools for MPI, short-comings and extensions of MPI, parallel I/O and fault tolerance, as well as parallel applications using MPI. The meeting is open towards other topics, in particular application experience and alternative interfaces for high-performance heterogeneous, hybrid, distributed memory systems. Topics of interest include, but are not limited to: - MPI implementation issues and improvements - Extensions to and shortcomings of MPI - Tools and environments for MPI - Hybrid and heterogeneous programming with MPI and other interfaces - Relation of MPI to alternative interfaces for hybrid/heterogeneous distributed memory systems - Interaction between message-passing software and hardware, in particular new high performance architectures - Fault tolerance in message-passing implementations and systems - Performance evaluation for MPI and MPI based applications- - Automatic performance tuning of MPI applications and implementations - Verification of message passing applications and protocols - Applications using message-passing, in particular in Computational Science and Scientific Computing - Non-standard message-passing applications - Parallel algorithms in the message-passing paradigm - Algorithms using the message-passing paradigm The meeting will feature contributed talks on the selected, peer-reviewed papers, invited expert talks covering upcoming and future issues, a vendor session where selected vendors will present their new developments in hybrid and heterogeneous cluster and high-performance architectures, a poster session, and a tutorial day. The scientific part of the conference is organized in cooperation with ACM SIGHPC. Conference proceedings will be published in the ACM Digital Library, which includes short and long papers, workshop papers, and posters. Selected high quality papers will be published in an international journals. There will also be a reward for the overall best paper from the academic conference. WORKSHOPS ------------------------------- IMUDI SPECIAL SESSION ON IMPROVING MPI USER AND DEVELOPER INTERACTION The IMUDI special session, to be held as a full-day meeting at the EuroMPI 2013 conference in Madrid, Spain, focuses on bringing together the MPI end-user and MPI implementor communities through discussions on MPI usage experiences, techniques, and optimizations. This meeting will focus on evaluating the MPI standard from the perspective of the MPI end-user (application and library developers) and address concerns and insights of MPI implementors and vendors. Unlike workshops associated with other conferences, the IMUDI session is still considered to be a part of the Euro MPI conference. Submissions will be reviewed separately to facilitate bringing together research publications falling into these "special focus" areas.

Energy-awareness is now a main topic for HPC systems. The goal of this workshop is to discuss latest researches on the impact and possibles leverages of communications for such systems. E2HPC2 solicits original and non-published or under-review articles on the field of energy-aware communication in HPC environment. This workshop is co-located with EuroMPI as MPI is the main communication interface in those environments. More info at: http://www.irit.fr/~Georges.Da-Costa/e2hpc2.html PBIO 2013: INTERNATIONAL WORKSHOP ON PARALLELISM IN BIOINFORMATICS In Bioinformatics, we can find a variety of problems which are affected by huge processing times and memory consumption, due to the large size of biological data sets and the inherent complexity of biological problems. In fact, Bioinformatics is one of the most exciting research areas in which Parallelism finds application. Successful examples are mpiBLAST or ClustalW-MPI, among many others. In conclusion, Bioinformatics allows and encourages the application of many different parallelism-based technologies. The focus of this workshop is on MPI-based approaches, but we welcome any technique based on: multicore and cluster computing, supercomputing, grid computing, cloud computing, hardware accelerators as GPUs, FPGAs, or Cell processors, etc. More info at: http://arco.unex.es/mavega/pbio2013/ SUBMISSION INFORMATION ------------------------------- Contributors are invited to submit a full paper as a PDF document not exceeding 6 pages in English. The title page should contain an abstract of at most 100 words and five specific, topical keywords. The paper must be formatted according to double-column ACM ICPS proceedings style. The usage of LaTeX for preparation of the contribution as well as the submission in camera ready format is strongly recommended. Style files can be found at http://www.acm.org/publications/icps-instructions/. New work that is not yet mature for a full paper, short observations, and similar brief announcements are invited for the poster session. Contributions to the poster session should be submitted in the form of a two page abstract. All contributions will be fully peer reviewed by the program committee.

And there's the point that makes fixing this stuff such a bitch: you almost never have a relationship with anyone except the carrier you connect through (and sometimes not even them :-). This is, incidentally, why my professional recommendation to people setting up "nailed up" links over the Internet is to move heaven and earth to get every point on the same carrier, or to make sure, at the very least that there is only one exchange point in the middle, and you're a customer of the carrier on both sides of it. Having to escalate through 3 or 4 carriers to get something fixed isn't just time consuming, it's often impossible. Social engineering NOC hotlines (as much as I hate to advocate it) is often the only solution; bring your Geek License. :-) Cheers, -- jra -- Jay R.

Network Configuration Management
by Chip Marshall 13 Mar '13

13 Mar '13

Just curious what people are using for network configuration manangement systems. I'm guessing most places have something built in-house, but before starting down that road I figured it would be a good idea to see if people have any off-the-shelf systems they like. Some features I'd like to have: * Interface configs * Firewall filter configs * BGP session configs * User management * Support for multiple router and switch vendors (at least Juniper and Cisco) -- Chip Marshall <chip(a)2bithacker.net> http://2bithacker.net/

This is a very nice piece of software for building automated maps of your network. You can do it online or feed it all your saved config files from a directory and it will auto-build OSPF and BGP or EIGRP maps of your network. It helped me spot one place where we forgot to turn on PIM. The map is dynamic and you can move your routers around and the links move with the shift on the map. It also flags routers that are missing a connection from the other end. -Hank >-Garrett

traffic accounting
by Joe Abley 12 Mar '13

12 Mar '13

Hi all, Imagine you have a number of GE and 10GE interfaces spread across multiple MX-class Juniper routers, and for each interface you want to maintain an accurate count of bytes sent, categorised by destination address. There is no layer-2 aggregation going on beyond the router, so no opportunity to create span ports on which to measure over on the side. Using optical splitters on each and every router interface and listening on the side using dedicated sniffers is an option, although it means tangles of fibre and potentially lots of sniffer boxes with lots of interfaces. I don't necessarily need a free or tremendously cheap solution, although it's always nice not to have to spend money. What are better approaches? Off-list would be fine if people have experience of this kind of thing; I can summarise if there is interest. Joe

Re: What Should an Engineer Address when 'Selling' IPv6 to Executives?

I would be concerned in strongly spruiking advantages of IPv6 to executives if an IPv6 dual stack solution is actually being deployed.

Easier to identify source/target of attacks > II. Simplified troubleshooting > A. No more need to include state table dumps in troubleshooting > B. tcpdump inside and tcpdump outside contain the same packets. > There are two well documented advantages to IPv6 dual stack: - responding to customers requesting IPv6 dual stack connectivity - excellent access to the IPv4 network IPv6 is a *different* network to IPv4 even if both networks happen to be carried on the same platforms (thank you Cisco, F5, Juniper etc - without this, our execs would be seriously baulking at having to replace fairly modern hardware). I have also noticed examples given of historic protocol changes. Not all of these are relevant as some of them only involved "middle" OSI layers, so do not apply very well to the IPv6->IPv6 transition. Greets Engineer Karl Pospisek (alias kpospisek(a)telstra.com)
