18 Dec '17

Please, accept our apologies in case of multiple copies of this CFP. ******************************************************************* The 7th International Workshop on Parallel and Distributed Computing for Large Scale Machine Learning and Big Data Analytics May 21, 2018 Vancouver, British Columbia CANADA http://parlearning.ecs.fullerton.edu In Conjunction with 32nd IEEE International Parallel & Distributed Processing Symposium. Scaling up machine-learning (ML), data mining (DM) and reasoning algorithms from Artificial Intelligence (AI) for massive datasets is a major technical challenge in the time of "Big Data". The past ten years have seen the rise of multi-core and GPU based computing. In parallel and distributed computing, several frameworks such as OpenMP, OpenCL, and Spark continue to facilitate scaling up ML/DM/AI algorithms using higher levels of abstraction. We invite novel works that advance the trio-fields of ML/DM/AI through development of scalable algorithms or computing frameworks. Ideal submissions should describe methods for scaling up X using Y on Z, where potential choices for X, Y and Z are provided below. Scaling up • Recommender systems • Optimization algorithms (gradient descent, Newton methods) • Deep learning • Sampling/sketching techniques • Clustering (agglomerative techniques, graph clustering, clustering heterogeneous data) • Classification (SVM and other classifiers) • SVD and other matrix computations • Probabilistic inference (Bayesian networks) • Logical reasoning • Graph algorithms/graph mining and knowledge graphs • Semi-supervised learning • Online/streaming learning • Generative adversarial networks Using • Parallel architectures/frameworks (OpenMP, OpenCL, OpenACC, Intel TBB) • Distributed systems/frameworks (GraphLab, Hadoop, MPI, Spark) • Machine learning frameworks (TensorFlow, PyTorch, Theano, Caffe) On • Clusters of conventional CPUs • Many-core CPU (e.g. Xeon Phi) • FPGA • Specialized ML accelerators (e.g. GPU and TPU) IMPORTANT DATES • Paper submission: February 16, 2018 AoE • Notification: March 16, 2018 • Camera Ready: March 30, 2018 PAPER GUIDELINES Submitted manuscripts should be upto 10 single-spaced double-column pages using 10-point size font on 8.5x11 inch pages (IEEE conference style), including figures, tables, and references. Format requirements are posted on the IEEE IPDPS web page. All submissions must be uploaded electronically at TBA TRAVEL AWARDS Students with accepted papers can apply for a travel award.

Stoomboot and grid clusters unavailable on 10 and 11 October
by Ronald Starink 06 Oct '11

06 Oct '11

Because of maintenance on the power infrastructure, the Stoomboot cluster and Nikhef grid cluster will be unavailable between Monday October 10, 16:00, and Tuesday October 11, 17:00. Please note that the maintenance only affects the compute nodes. Other services (including grid storage) are not affected. To enable jobs to complete before shutting down the compute nodes, we will close the batch queues on Monday morning. Regards, Ronald

downtime Nikhef grid cluster and storage postponed to 8-Mar-2011
by Ronald Starink 09 Feb '11

09 Feb '11

Dear users, The downtime of the Nikhef grid cluster and storage systems that was originally scheduled for February 15 has been postponed. The replacement operation will take place at *Tuesday March 8* (10:00 - 17:00). During the operation, all grid compute and storage services will be unreachable. Until Thursday March 10 (17:00), the systems may (temporarily) be unavailable to test and fix any remaining problems. Please note that this intervention may affect users of the Stoomboot cluster who read data from grid storage element tbn18.nikhef.nl.

downtime Nikhef grid cluster and storage: 15-Feb-2011 (+ at risk until 17-Feb-2011)
by Ronald Starink 02 Feb '11

02 Feb '11

Dear users, On Tuesday February 15, 2011, the entire Nikhef grid facility will be unavailable to replace a central component in the network setup. Consequently, it will not be possible to use the compute service, the storage systems (connected via tbn18.nikhef.nl) and other grid services. The replacement is a complex operation. There is a small probability that certain services will not be functioning properly after the replacement. Therefore, we scheduled an "at risk" downtime until Thursday February 17. During this period, services may (temporarily) be unavailable and we will test and fix any remaining problems. We apologize for the inconvenience. Regards, Ronald

Nikhef grid computing facility closed
by Paco Bernabé 26 Oct '10

26 Oct '10

Dear users, In the course of last week, security experts identified 3 separate high risk vulnerabilities in the operating system used at our grid facility. We managed to neutralize the first two, but unfortunately, there is no known protection against the third one. We have therefore decided to close the Nikhef grid computing facility, to ensure our systems remain safe. As soon as a fix is available, we will apply it and enable access to the systems again. We'll inform you when that has happened. The storage systems remain available. We apologize for the inconvenience, Paco. ============================================ F.J.

Nikhef 'grid farm' login: password changed
by David Groep 13 Jan '10

13 Jan '10

Dear Nikhef local Grid users [de Nederlandse vertaling volgt op de Engelse tekst] [and my apologies to those on this list who are not local Nikhef users] Following the introduction of integrated identity management at Nikhef, the new email service, and the connection of the Nikhef accounts with the SURFfederation, the password you used to gain access to the 'grid farms' at Nikhef (the user interface 'bosui.nikhef.nl' and related machines) may have changed. Whatever it was before, it is now set to be THE SAME as your regular Nikhef unix password, i.e., the one used to login to your desktop, to 'login.nikhef.nl', and for email. If you had different passwords for 'bosui' and for the desktop systems, you should from now onwards ONLY use your 'desktop' password. We apologize for any inconvenience caused. For questions, you can contact Grid Support any time (via grid.support(a)nikhef.nl) Regards, David Groep. -------------------------------------------------------------------------- Beste Nikhef Grid gebruikers, Met het invoeren van gecoordineerd computeridentiteitsbeheer bij Nikhef, de nieuwe email dienst, en met het koppelen van Nikhef met de onderwijs en onderzoeksfederatie "SURFfederatie" is ook de toegang tot de 'grid' en 'farm' machines op Nikhef gelijkgetrokken. Dit betekent dat vanaf nu het wachtwoord voor aanloggen op de grid gebruikerskoppelingsmachine 'bosui.nikhef.nl' met HETZELFDE wachtwoord gebeurt als het aanloggen op de Unix bureausystemen, op de publieke aanlogdienst 'login.nikhef.nl', en op de email dienst. Wanneer je eerder verschillende wachtwoorden gebruikte voor 'bosui' en voor 'login', dan dien je vanaf nu nog uitsluitend je 'login' wachtwoord te gebruiken. Onze excuses voor eventueel ongemak. Bij vragen kun je altijd terecht bij Grid Support (grid.support(a)nikhef.nl) Met vriendelijke groeten, David Groep -- David Groep ** Nikhef, Dutch National Institute for Sub-atomic Physics,PDP/Grid group ** ** Room: H1.50 Phone: +31 20 5922179, PObox 41882, NL-1009DB Amsterdam NL **

changes in queue names and properties
by Ronald Starink 26 Nov '09

26 Nov '09

To improve the uniformity of the computing resources at the various BiG Grid sites towards the users, all sites will define a set of identical queues (concerning name and properties) on their computing systems. At grid site NIKHEF-ELPROD, we have created new queues that will replace some of the existing queues. The following queues will be removed from the systems per December 7th, 2009: * "test": replaced by queue "infra"; * "qshort": replaced by queue "short" with a maximum wall time of 4 hours; * "qlong": replaced by queue "medium" with a maximum wall time of 36 hours. Note: the replacing queues can already be used. How does this affect users of the computing infrastructure? * Users who do not explicitly submit jobs to a specific queue, do not have to take any action; * Users who put a statement in the .jdl file to select a specific queue may have to change the queue name in the .jdl file; * Users who directly submit jobs to a Computing Element and queue via the command glite-wms-job-submit using the option "--resource <CE>:2119/jobmanager-pbs-<QUEUE>" may have to change the name for <QUEUE>. Best regards, Ronald Starink
