[OMPI users] CfP Workshop on XEN in HPC Cluster and Grid Computing Environments (XHPC)
=== CALL FOR PAPERS (XHPC'06) Workshop on XEN in High-Performance Cluster and Grid Computing Environments as part of: The Fourth International Symposium on Parallel and Distributed Processing and Applications (ISPA'2006). Sorrento, Italy === List-Post: users@lists.open-mpi.org Date: 1-4 December 2006 ISPA'2006: http://www.ispa-conference.org/2006/ Workshop URL: http://xhpc.ai.wu-wien.ac.at/ws/ (due date: August 4, 2006) Scope: The Xen virtual machine monitor is reaching wide-spread adoption in a variety of operating systems as well as scientific educational and operational usage areas. With its low overhead, Xen allows for concurrently running large numbers of virtual machines, providing each encapsulation, isolation and network-wide CPU migratability. Xen offers a network-wide abstraction layer of individual machine resources to OS environments, thereby opening whole new cluster-and grid high-performance computing (HPC) architectures and HPC services options. With Xen finding applications in HPC environments, this workshop aims to bring together researchers and practitioners active on Xen in high-performance cluster and grid computing environments. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections. Presentations may be accompanied with interactive demonstrations. The workshop will end with a 30 min panel discussion by presenters. TOPICS Topics include, but are not limited to, the following subject matters: - Xen in cluster and grid environments - Workload characterizations for Xen-based clusters - Xen cluster and grid architectures - Cluster reliability, fault-tolerance, and security - Compute job entry and scheduling - Compute workload load levelling - Cluster and grid filesystems for Xen - Research and education use cases - VM cluster distribution algorithms - MPI, PVM on virtual machines - System sizing - High-speed interconnects in Xen - Xen extensions and utilities for cluster and grid computing - Network architectures for Xen clusters - Xen on large SMP machines - Measuring performance - Performance tuning of Xen domains - Xen performance tuning on various load types - Xen cluster/grid tools - Management of Xen clusters PAPER SUBMISSION Papers submitted to each workshop will be reviewed by at least three members of the program committee and external reviewers. Submissions should include abstract, key words, the e-mail address of the corresponding author, and must not exceed 15 pages, including tables and figures, and preferably be in LaTeX or FrameMaker, although submissions in the LNCS Word format will be accepted as well. Electronic submission through the submission website is strongly encouraged. Hardcopies will be accepted only if electronic submission is not possible. Submission of a paper should be regarded as a commitment that, should the paper be accepted, at least one of the authors will register and attend the conference to present the work. An award for best student paper will be given. http://isda2006.ujn.edu.cn/isda/author/submit.php Format should be according to the Springer LNCS Style http://www.springer.de/comp/lncs/authors.html It is expected that the proceedings of the workshop programs will be published by Springer's LNCS series or IEEE CS. IMPORTANT DATES Paper submission due: August 4, 2006 Acceptance notification: September 1, 2006 Camera-ready due: September 20, 2006 Conference: December 1-4, 2006 CHAIR Michael Alexander (chair), WU Vienna, Austria Geyong Min (co-chair), University of Bradford, UK Gudula Ruenger (co-chair), Chemnitz University of Technology, Germany PROGRAM COMMITTEE Franck Cappello, CNRS-Université Paris-Sud, France Claudia Eckert, Fraunhofer-Institute, Germany Rob Gardner, HP Labs, USA Marcus Hardt, Forschungszentrum Karlsruhe, Germany Sverre Jarp, CERN, Switzerland Thomas Lange, University of Cologne, Germany Ronald Luijten, IBM Research Laboratory, Zurich, Switzerland Klaus Ita, WU Vienna, Austria Franco Travostino, Nortel CTO Office, USA Andreas Unterkircher, CERN, Switzerland GENERAL INFORMATION This workshop will be held as part of ISPA 2006 in Sorrento, Italy - http://www.sorrentoinfo.com/sorrento/sorrento_italy.asp.

Re: [OMPI users] F90 interfaces again
I think that we've fixed everything with respect to f90 except the "large" interface. Let us know if we either missed something or you find something new.

[OMPI users] Why does it suddenly not run?
This morning I was running mpirun -v --mca btl mvapi,self -np 12 --hostfile ompimachinefile oodles . les_test1100k -parallel >> ./les_test1100k/log12 & with openmpi-1.2a1r10111 and everything worked and still works as expected. Now I tried to start a second (very same) job with the following error message as a result: [stokes:29489] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_init_stage1.c at line 302 -- It looks like orte_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during orte_init; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): orte_session_dir failed --> Returned value -1 instead of ORTE_SUCCESS -- [stokes:29489] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_system_init.c at line 42 [stokes:29489] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_init.c at line 49 -- Open RTE was unable to initialize properly. The error occured while attempting to orte_init(). Returned value -1 instead of ORTE_SUCCESS. Has anybody an idea what the error might be or how to trag it down? Regards Jens
Re: [OMPI users] Why does openMPI abort processes?

Generally, this is because multiple processes in your job aborted (exited with a signal or before MPI_FINALIZE) and mpirun only prints the first abort message. You can modify how many abort status messages you want to receive with the -aborted X option to mpirun, where X is the number of process abort messages you want to see. The message generally includes some information on what happened to your process. Hope this helps, Brian
