#1674: Switch to OpenBLAS -------------------------+-------------------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Other | Version: development version Keywords: | -------------------------+-------------------------------------------------- OpenBLAS is a BLAS and LAPACK library that is significantly more efficient that the standard ("reference") BLAS. I suggest we switch the ET thorn list to ExternalLibraries/OpenBLAS instead of ExternalLibraries/BLAS and ExternalLibraris/LAPACK. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1674> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1390: parameter file parser aborts when findeing first error --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- The attached parfile contains multiple errors (one per line). However the parameter file parser only reports the first one, then stops. This makes verifying parfiles for correctness hard. It might be good to defer aborting until the end of the file or until a larger number of parsing errors were encountered. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1390> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1276: Intel 2013.1.117 mis-compiles NewRad

#1276: Intel 2013.1.117 mis-compiles NewRad -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: NewRad | -----------------------------------+---------------------------------------- Intels compiler fails (with -O2) to push values for bmin onto the stack in lines 316 of newrad.cc and line 126 of extrap.cc. Adding printf's for bmin perturbs the bug out of existence, but adding a printf of the address of bmax and reveals that at the time extrap_kernel is call the integer just before this address is still the initialization value of bmin[2] and not the correct value. The attached patch disables optimization for the two driver functions affected (but not the actual kernel). The patch is specific (via an #if) for this particular compiler and version. What is the best way of handling this? Target any intel version starting from the known failing one until we know of known good one? Or starting from an older known good one (that would be intel 11 in my case). Hopefully no similar bug is triggered by Carpet's use of the same idiom. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1276> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1439: SSL certificate check failing

#1439: SSL certificate check failing --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Other | Version: development version Keywords: | --------------------+------------------------------------------------------- The check for SSL certificates in line 535: {{{#perl # check for svn SSL problems if ( $rec{"TYPE"} eq "svn" && defined $rec{"AUTH_URL"} ) { my $base = $rec{"AUTH_URL"}; $base =~ s/(https\:\/\/[\w\.]+)\/(.*)$/$1/i; unless ( defined $svn_servers{$base} ) { my $ret = `$svn --non-interactive info $rec{AUTH_URL} 2>&1`; if ( $ret =~ /Server certificate verification failed/ ) { $svn_servers{$base} = 0; } else { $svn_servers{$base} = 1; } } } }}} is incorrect since eg for the ET manifest where {{{ AUTH_URL=https://svn.einsteintoolkit.org/$1/trunk }}} the executed svn command is: {{{ svn --non-interactive info https://svn.einsteintoolkit.org/$1/trunk 2>&1 }}} which actually returns and error: {{{ svn: E175002: Unable to connect to a repository at URL 'https://svn.einsteintoolkit.org/trunk' svn: E175002: The OPTIONS request returned invalid XML in the response: XML parse error at line 1: Extra content at the end of the document (https://svn.einsteintoolkit.org/trunk) }}} but the code does not test for svn failures at all at this point. The simplest fix would be to move the check further down where {{{$1}}} has been replaced by an actual value, eg into the loop: {{{ # we are splitting each group of components into individuals # to check for existence. they will now be passed individually to # the checkout/update subroutines. this will take up more memory, # but it should make it easier if the user decides to add another # component from the same repository later my @checkouts = split( /\s+/m, $rec{"CHECKOUT"} ); foreach my $checkout (@checkouts) { }}} in line 565 which however causes the test to run for every single CHECKOUT item. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1439> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #394: Testsuite log file should contain more information

#394: Testsuite log file should contain more information -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: testsuites | -------------------------+-------------------------------------------------- It is useful to look at the testsuite log file for information about how the tests were run. For example, which compiler was used, and with what compiler options. We need to balance this against providing information which will always change, making diffs hard to read. The most extreme case would be to output all make variables. Maybe better would be to output CC, CFLAGS, CXX, etc. Another option would be to parse these and say "intel compiler", "gcc", "pgi" etc. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/394> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1717: hwloc: lnuma & lltdl *really* required? -----------------------------------+---------------------------------------- Reporter: zachetie@… | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- I downloaded the ET devel version (ca. Nov 26) on my (ubuntu) laptop and compiled it, using gcc. I compiled to the linker stage, and the linker complained: ld: cannot find -lnuma ld: cannot find -lltdl I found references to these libraries in: configs/[buildname]/bindings/Configuration/Capabilities/make.HWLOC.defn After removing these references, the code compiled and seemed (on the surface) to run okay. Are these libraries really necessary? I ask because every time I need to install ET on a new machine, it would be more convenient if the step "apt-get install libnuma-dev libltdl-dev" were left out, particularly since reliable Internet access may not exist at that time. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1717> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1656: CarpetInterp and MoL do not work properly together

#1656: CarpetInterp and MoL do not work properly together --------------------+------------------------------------------------------- Reporter: hinder | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: Carpet | Version: development version Keywords: | --------------------+------------------------------------------------------- I am trying to integrate interpolated quantities using MoL. I call the interpolator in MoL_CalcRHS, and want it to perform only a spatial interpolation of the current content of timelevel 0. This current content is what has been set by MoL; it is not the final value that will be at t_{n+1} or was at t_N, but is the intermediate value that should be used when computing the RHS at a given MoL substep. Since MoL does not set the Carpet time hierarchy values, CarpetInterp seems to get confused about how to do the interpolation. I need to tell CarpetInterp not to interpolate in time at all, but to use timelevel 0 only. Unfortunately, setting the interpolator option to use only one timelevel does not work. There is commented-out code to "use cctk_time to decide whether to interpolate", which essentially guarantees that no time interpolation will happen (since the interpolation is requested for cctk_time, and the current time is cctk_time, so they are always equal). Re-enabling this code allowed me to achieve 4th order convergence for integrated interpolated quantities, though I am not sure I understand everything that is going on in CarpetInterp. I have added a parameter which controls this, and with this parameter set to the default, nothing changes (i.e. it is not going to change anyone's results unless they set the parameter). I would like to commit this, so that collaborators can work off the same version. Since the patch is very small, I hope this will not add too much unneeded complexity. Is it OK to commit? Patch is attached. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1656> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
