GetComponents can also be used to +update an existing checkout, but since some components might have changed +location or have been removed from the toolkit you should try a new checkout +whenever possible instead. + +See the <a href="http://einsteintoolkit.org/download/">Download</a> page on +the Einstein Toolkit website for download instructions. + +<h4>Remaining issues with this release</h4> + +<ul> + <li>Certain machines need to be configured specially in Simfactory because the remote directories cannot be determined automatically just from the username. See the Machine notes below.</li> + <li>CarpetIOHDF5: When the new parameter CarpetIOHDF5::output_symmetry_points is set to "yes", then symmetry points are not actually output if CarpetIOHDF5::output_buffer_points has been set to "no".</li> + <li>Recovering with Carpet: The maximum number of timelevels that can be recovered is Carpet::prolongation_order_time+1. This is usually the case, but it is possible to write parameter files e.g. with prolongation_order_time=1 that use 3 timelevels. This bug manifests in an assert() failure when recovering from checkpoints. The work-around is to either increase Carpet::prolongation_order_time or decrease the number of timelevels for the grid function in question accordingly.</li> +</ul> + +<h4>Machine notes</h4> +<ul> + <li>Kraken + defs.local.ini needs to have sourcebasedir = $HOME configured for this machine. You need to determine $HOME by logging in to the machine.</li> + <li>LoneStar and Ranger + defs.local.ini needs to have sourcebasedir = $WORK and basedir = $SCRATCH/simulations configured for this machine. You need to determine $WORK and $SCRATCH by logging in to the machine.</li> + <li>Pandora + The LSU system pandora has at the time of writing not only severe problems of compiling Cactus (can crash the filesystem), but in part due to this also outstanding are some failing testsuite results. Please contact Peter Diener at CCT (LSU) before trying to use this machine.</li> +</ul> + +All repositories participating in this release carry a branch +<tt>ET_2012_05</tt> marking this release. These release branches will +be updated if severe errors are found. + +This release has been tested on about twenty systems and +architectures, including the following: + +<ul> +<li>Workstations (AMD, Linux)</li> +<li>MacBook Pro notebook (Intel, Mac OS X)</li> +<li>Lenovo T61p notebook (Intel, Linux)</li> +<li><a href="http://supercomputers.aei.mpg.de/">Datura</a>, AEI (cluster, Linux)</li> +<li><a href="http://www.nics.tennessee.edu/computing-resources/kraken">Kraken</a>, NICS (Cray XT5, Linux)</li> +<li><a href="http://www.hpc.lsu.edu/systems/system.php?system=Philip">Philip</a>, LSU (Intel cluster, Linux)</li> +<li><a href="http://www.loni.org/systems/system.php?system=QueenBee">Queen Bee</a>, LONI (Intel cluster, Linux)</li> +<li><a href="http://services.tacc.utexas.edu/index.php/ranger-user-guide">Ranger</a>, TACC (AMD cluster, Linux)</li> +<li><a href="http://services.tacc.utexas.edu/index.php/lonestar-user-guide">Lonestar</a>, TACC (Intel cluster, Linux)</li> +<li><a href="http://www.sdsc.edu/us/resources/trestles/">Trestles</a>, SDSC (AMD cluster, Linux)</li> +<li><a href="http://www.nersc.gov/users/getting-started/">Hopper</a>, NERSC (Cray XE6, Linux)</li> +</ul> + +The <a href="http://www.simfactory.org/">Simulation +Factory</a> contains ready-to-use configuration details for more than +40 additional systems, including most HPC systems +at <a href="http://www.loni.org/">LONI</a>, +<a href="http://www.nersc.gov/">NERSC</a>, +<a href="http://www.rzg.mpg.de/">RZG</a>, +and <a href="https://www.xsede.org/">XSEDE (TeraGrid)</a>. + +The Einstein Toolkit web site contains online documentation for its +components, and pointers for using it to build your own code.
