From gallen at cct.lsu.edu Sat Nov 10 16:48:43 2007 From: gallen at cct.lsu.edu (Allen Gabrielle) Date: Sat, 10 Nov 2007 16:48:43 -0600 Subject: [Users] Cactus News and Supercomputing 2007 Message-ID: <6DCCE233-776C-43A0-918C-CE7351DB50F8@cct.lsu.edu> Greetings to all Cactus users ! It has been quite some time since the last Cactus release (Cactus 4.0 Beta 15). Since then, besides bug fixing, user support and enjoying life, we have been working to nurture a broader range of application areas using Cactus, and secure funding for infrastructure and application development. This message is to update everyone on our recent progress, and starts a new phase of more regular newsletters. New Grants: o ALPACA: NSF award under the Software Development for Cyberinfrastructure (SDCI) program to develop tools in Cactus for application level performance and correctness analysis. Under this award we will provide: - new fault tolerant capabilities - new performance monitoring capabilities - new interactive debugging capabilities - new user friendly interfaces o XiRel: NSF award under the Physics at the Information Frontier (PIF) solitication for next generation infrastructure for numerial relativity. With our good colleagues at RIT and Penn State this award will - develop a highly scalable, efficient and accurate adaptive mesh refinement layer based on the existing Carpet driver, - provide improved community support and infrastructure - lead towards community toolkits and data services for numerical relativity o PARCA: NASA STTR award to provide a PARAMESH interface in Cactus. With our good colleagues at Decisive Analytics Corporation (DAC), UMD, and NASA Goddard this award will develop a highly scalable, efficient and accurate adaptive mesh refinement driver based on PARAMESH. o UCoMS: DOE award to develop grid community scenarios in petroleum engineering. Under this award we are developing a reservoir simulator in Cactus which will allow for high throughput flow simulations. We will also be developing tools for optimization and inverse modeling. o CyberTools: This large NSF award is to develop cyberinfrastructure across the state of Louisiana. Cactus is involved as an application framework for multiscale fluid dynamics and molecular dynamics, and with this award we will extend our Cactus CFD Toolkit. o CoMI: DOD award to develop a coastal modeling framework for studying the Louisiana coastal region, building on the CFD toolkit. o DynaCode: NSF award to develop dynamic data driven application systems based around real time coastal scenarios. This award is funding the development of Cactus Version 5 which will provide capabilities for more dynamic scheduling and adaption. o AstroGrid-D: A research project funded by the German Ministry for Education and Research to make astrophysical codes ready for the Grid. For Cactus, which is one of the application use cases in AstroGrid-D, grid-enabled simulation monitoring and steering methods and a Cactus user portal are being developed. New Application Areas: Through different grants and projects, we are now working with new applications in coastal modeling, computational fluid dynamics, reservoir simulations, and shrimp modeling. New People: o We have recently been joined by Jian Tao, a soon to be PhD in computational astrophysics from Washington University, who will be working primarily on adaptive mesh refinement in Cactus. o Maciej Brodowicz from CCT is strengthening our tools development and performance analysis. o LSU students Junaid Ahmed and Tyler Barker have joined the team to help with the development of Eclipse interfaces for Cactus. o Prof Mayank Tyagi (Petroleum Engineering), Prof Chris White (Petroleum Engineering) and Prof Jim Chen (Civil Engineering) from LSU are helping in developing new application areas using Cactus. Supercomputing 2007: A number of us will be in Reno next week for SC07. Cactus demos will be given at the LSU booth, please come and say hello: 1) Erik Schnetter will show tools for petascale computing and Cactus 1:30 PM, Tuesday, 13 November 2007 1:00 PM, Thursday, 15 November 2007 2) The Cactus "Black Oil" application will run as part of a distributed workflow showing the use of Ensemble Kalman Filters in the Petroleum Engineering demo 1:00 PM, Tuesday, 13 November 2007 11:00 AM, Wednesday, 14 November 2007 3) Mayank's CFD Toolkit demo will show basic functionality in the toolkit and its use for coastal and reservoir simulations 11:00 AM, Thursday, 15 November 2007 4) Ed Seidel will demonstrate the LONI environment, including showing Cactus scaling to over 4000 processors of the new 50TF Queen Bee machine 2:30 PM, Wednesday, 14 November 2007 5) Burkhard Zink will talk about his astrophysics work using Cactus 3:30 PM, Wednesday, 14 November 2007 Any suggestions and ideas with regard to the future development of Cactus would be appreciated. Thanks again for your support !

Our web page describes how to set up VisIt, and how to install a reader for Cactus/Carpet data. VisIt also supports remote visualisation. One needs to add a "host profile" for each remote host that should be accessed remotely. This is described in the VisIt manual; we have also added corresponding instructions to the VisIt web page above. Please help us keep these instructions useful by suggesting extensions or corrections if necessary. -erik -- Erik Schnetter My email is as private as my paper mail.
