Question about SummationByParts
by Heeil Kim 28 Feb '12

28 Feb '12

Hi all, I'd like to know the effect of SummationByParts when it is activated. If it's activated, does it touch by default some finite-differencing scheme? For example, In qc0-mclachlan.par, SummationByParts is activated with 4th order, does it mean all 1st derivatives are replaced with SBP? Or in SBP in qc0 does nothing because it's never been inherited by other thorns? Cheers, Hee Il

Present were: Peter, Frank, Christian, Tanja, Roland, Josh, Ian, Bruno * no new about elliptic solver, Erik might now details Spring Workshop in Atlanta: * Tanja put a direct link to book a room in the reserved block onto the wiki http://hamptoninn.hilton.com/en/hp/groups/personalized/A/ATLGTHX-ETW-201204… * will reserve second block at Hotel Midtown (~80 plus taxes) which is less convenient (about 15min walk to student center, MARTA to APS conference) * Dennis will prepare updated Cactus virtual machine images. Please try them out and report if anything is missing. * please attach your name to sessions within the schedule https://docs.einsteintoolkit.org/et-docs/Schedule_Proposal by Wednesday * Workshop Flyer updated version will be ready today or tomorrow * invited speakers (tentative, incomplete): Matt Duez, John Wise * Bruno will provide list of NR topics and add a link to the wiki, can then discuss what to cover ET paper: * have received feedback from referee Yours, Roland

Meudon_Bin_NS initial Data
by Petr Tsatsin 27 Feb '12

27 Feb '12

Hello, I'm trying to use initial data from Meudon for a binary neutron stars. How do I actually set file names of the files to read from? I was wondering if you could provide some examples of a par files? -- Petr Tsatsin Graduate Student - Department of Physics Charles E.

OpenMP "for collapse" directives
by Erik Schnetter 26 Feb '12

26 Feb '12

The OpenMP standard 3.0 (released almost four years ago, already superseded by 3.1) introduced the concept of "collapsed for loop parallelisation". This looks as follows: #pragma omp parallel for collapse(3) for (int k=0; ...) for (int j=0; ...) for (int i=0; ...) { ... loop body... Without the "collapse" directive, only the outermost loop is parallelised. The "collapse" directive specifies that all three loops can be parallelised. This can improve performance, in particular if there are many threads, if the k loop is small, or if the looping region is a very deformed rectangle. -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.perimeterinstitute.ca/personal/eschnetter/

MoL Arrays
by Christian Reisswig 24 Feb '12

24 Feb '12

Dear all, I am wondering why MoL does not have support for arrays anymore (the provided functions are all commented out). I guess there is a particular reason for this? Thanks for any hints! Christian

Hi, I tried to install ETK in Hopper. Get a simple error after 'simfactory/bin/sim build': Using configuration: sim Building sim /bin/bash: module: command not found Also tried in bash modus but did not help Have a question.

Dear ADMBase, it would be highly appreciated if you could stop syncing yourself all the time for no good reason. My Uschi evolution code is syncing you already. Please calm down and have a beer. Yours, Uschi Gamma

ETK in Carver

Dear Colleagues, I am trying to install ETK in Carver at NERSC. By chance I found this link http://mail.cct.lsu.edu/pipermail/simfactory/2010-September/000306.html I want to be sure it is the same machine. I am updating ./Getcomponents -a ... right now Do somebody have experience with this machine? I found a carver.ini in simfactory/mbd/machines How can I use this .ini while doing simfactory/bin.sim build to create the .exe ? Thanks, Jose

Re: [Users] ETK webpage tutorial not working
by Jose Fiestas Iquira 22 Feb '12

22 Feb '12

Hello, Now the page works. Do you mean that installing Cactus in my laptop should be easier than doing it in a CPU cluster? The first problem I got in the CPU cluster is that hg was not found, and soft add +python, etc can not be done because not installed. Can't I somehow avoid this step?
