James Amundson presented a talk entitled "Accelerator Beam Dynamics on Multicore and GPU (and MIC) Systems" at the 2014 SIAM Conference on Parallel Processing for Scientific Computing, February 2014. Th slides are available here.
Synergia is featured in today's SCD column in Fermilab Today.
The Synergia workflow system, Job_manager, now includes support for composite batch jobs. Batch jobs can now be created using multiple values for individual paramters. Job_manager now creates separate subjobs for each set of parameter values and combines them into a single master job. This development allows users to directly utilize leadership-class resources for parameter scans.
Synergia now reads accelerator lattices in MadX format
The ComPASS collaboration received funding under the DOE SciDAC-3 program to develop and apply state-of-the-art techniques in high performance computing and applied mathematics to problems in accelerator modeling and design.

Recent work on utilizing single- and multi-GPU resources for Synergia has resulted in a factor of 20x speedup.
Execution time for a standard synergia problem on multiple platforms
Recent optimization work for Synergia2 on multicore architectures has resulted in an improvement in strong scaling behavior by at least a factor of 8.

Please mark your calendars: the 2010 ComPASS all hands meeting will be in Menlo Park on December 7th and 8th, hosted by SLAC. The focus of the meeting will be on reviewing the current state of code development and application activities, enhancing collaborative work, and preparing for SciDAC3.
Greg Schussman, Lie-Quan Lee, Liling Xiao, Cho Ng and Kwok Ko of SLAC and Ken Moreland of Sandia National Laboratories won a 2010 SciDAC OASCR Award for Outstanding Achievement in Scientific Visualization at the SciDAC Conference held in Chattanooga, Tennessee, July 11-15, 2010 for the simulation of short bunch wakefields in an ERL vacuum chamber using parallel hp refinement with a moving window, performed on the world’s fastest supercomputer at Oak Ridge National Laboratory and visualized using ParaView.
Accelerator Code Workshop CW10 for the ACE3P (Advanced Computational Electromagnetics 3P) code suite will be held at SLAC, September 22-24, 2010. For details, see http://www-conf.slac.stanford.edu/CW10/.
The ComPASS code BeamBeam3d has been enhanced at Fermilab and used to improve Tevatron running.
For the International Linear Collider to run at maximum performance, each of its 27,000 cavities must be designed as precisely as possible. Read more
Fully 3D multi-beam-dynamics-process simulations of the Fermilab Tevatron have been used to support a change of chromaticity at the Tevatron, thus leading to reduced losses.
At Jefferson Lab, scientists use CEBAF (Continuous Electron Beam Accelerator Facility) and three experimental halls to study quarks, gluons, protons and neutrons inside the nucleus with CEBAF and its three experimental halls. Read more at http://www.scidac.gov.
Synergia was profiled running on BlueGene/P.

CW09 will be held at SLAC on September 4, 2009. See this link for details: http://www-conf.slac.stanford.edu/CW09.
The article "NEXT-GENERATION Visualization Technologies: Enabling Discoveries at EXTREME Scale" in SciDAC Review Magazine, Number 12, Spring 2009, highlights a collaboration between SciDAC Institute IUSV and ComPASS on visualization of accelerator cavity simulation using ParaView.
The article describes the work carried out by ComPASS researchers at SLAC in understanding wakefields in linear colliders through an INCITE award.
ComPASS & ITAPS collaborators won the best meshing technical poster award at the 17th International Meshing Roundtable conference.
J. R. Cary and T. Austin, supported in part by the COMPASS project, won one of the 10 "OASCR" visualization awards given out at the annual meeting of the U.S. Department of Energy’s Scientific Discovery through Advanced Computing (SciDAC) program held in Seattle July 13–17.
