Frank,

thanks for the correction.  I have applied your patch.

The fact that this code did not compile before indicates that the C  
version of the macros has not yet been thoroughly tested.  You should  
be very careful if you want to use it.  Historically, only the  
Fortran version has of ADMMacros been used.

The code in ADMMacros is hand-written and therefore tends to contain  
errors.  These days, many people autogenerate code using a variety of  
systems based on Maple or Mathematica; I'm sure you know Kranc  
<http://numrel.aei.mpg.de/Research/Kranc/>, and there are other,  
similar systems.  We (the LSU group) recently implemented our  
harmonic formulation of the Einstein equations using Maple directly.

Generating code automatically also has certain other advantages.  For  
example, one can perform high-level optimisations of the code  
depending on the machine for which one generates code.  This may  
become important in the future as machines have more processors  
(cores) and/or less memory per node.  With hand-written code these  
optimisations need to be applied manually, while a code-generation  
system can generate the corresponding optimisations automatically.

If one wanted e.g. to use or to experiment with multi-threading or  
OpenMP, which can potentially save a significant amount of memory,  
one would have to change only a few lines of Kranc to generate the  
corresponding directives.  This will allow much faster experiments  
than manually annotating all existing loops in a production code,  
probably protected by #ifdef statements to be able to switch forth  
and back.

There are a couple of places where the C versions of the macros are
simply wrong. I have the impression that at some point in the very
early history of the code, when they were experimenting with things
like how to finite difference the advection terms and how the
constraints are added into the BSSN, they stopped maintaining both
versions of the macros simultaneously.

If you really need C macros, I agree with Erik that it's probably
easier to start from scratch than to go through each macro and
check that the C and Fortran versions are compatible.

Denis.

I know that those errors mean that nobody used them at all yet. I would
only use them to debug some things, but maybe I am really better off by
using Fortran code for that.
On the other hand, _some_ of the macros are used, also by C code.

What can we do to improve the situation? We could
a) remove the code, which is wrong
b) correct the wrong code
c) rething the whole Macros

c) might be the best for the long term, but for a) and b) we have to
identify the wrong code first. Can you point at some places?

Where is that?  That is, which C thorn uses these macros?

Indeed; this calculates the Ricci tensor using the C version of the  
macros.

I seem to remember that the worst offenders had to do with
advective terms and whether they were applied consistently and
correctly, and mostly in the evolution equations.
I think the standard things, like K_ij or the inverse of the
metric, are likely okay. So if the thorns are just doing
analysis, they might get away with it. Worth a check, though.
Once you start using the source equations, eg. to calculate
'd/dt K_ij' or anything to do with Gamma~, then I'd be more
worried.

Hi, Erik. 

I have good news. When I sent that message, the executable file wasn't been
generated. That situation hadn't solution with my old linux distribution and its
problems !! ... So, I've decided to install Fedora Core 6 in my machine, and I
did it. By now, my system works very well. I can compile Cactus making:

 claudiob> gmake Bench_BSSN_PUGH_single  F90=gfotran

The Result is the executable is generated and works correctly.

Thank you for your suport.
My best regards,

Claudio.

From schnetter at cct.lsu.edu  Fri Jul  6 07:57:24 2007

Subject: [Developers] Infrastructure for initial data setup
Message-ID: <106FBFC4-A024-40F5-8BF8-C0B70083FCD3@cct.lsu.edu>

There is currently no infrastructure in Cactus which helps decide how  
to set up initial data.  With mesh refinement, there are several  
incompatible ways in which initial data thorns can set up initial  
data.  Depending on this, evolution thorns may have to adapt, or mesh  
refinement drivers may schedule evolution differently.

This lack of infrastructure leads to problems, since initial data  
thorns, evolution methods, and the Carpet mesh refinement driver are  
not well coordinated.  The user who writes parameter files has to  
know the behaviour of each of these, and then choose parameters so  
that these pieces work together correctly.  There is no entity in  
Cactus which knows how initial data should be set up, and which could  
provide error checking.  This leads to inconsistencies which are  
difficult to detect.

I suggest to create a new thorn CactusBase/InitBase.  It would  
contain the following README:

----------------------------------------
Specify how initial data are to be set up.  There are three
possibilities:

1. The initial data thorn sets up data on one time level, while other
    time levels are scratch space.  The time evolution method must
    start up from a single time level.  (This is the default.)

2. The initial data thorn sets up data on exactly one time level, and
    is called once for each active time level.  (This means that the
    initial data thorn can only access the current time level.)

3. The initial data thorn sets up data on all active time levels.
    (This makes it necessary that the initial data thorn checks the
    number of active time levels.)
----------------------------------------

Apart from this README, thorn InitBase would contain one restricted  
parameter "initial_data_setup_method" which allows users to choose  
the desired behaviour in the parameter file.  All initial data  
thorns, evolution methods, and drivers then have to check the value  
of this parameter, and either adapt their behaviour or signal an error.

Hi,

your proposal seems a good idea to me.

Subject: [Developers] portland compiler and ADMConstraints runtime error
Message-ID: <793f07c70707120239h3fbee7d9wd444d3fabce2fd21@mail.gmail.com>

dear all

I'm trying to compile a standard cactus-carpet-whisky (dev) configuration
cheked out recently,
with these options:

F77=pgf77
F90=pgf90
F90FLAGS=-Mx,125,0x200 -Mextend
F77FLAGS=-Mx,125,0x200 -Mextend

it compiles but I obtain this runtime error:

Subject: [Developers] Steerable parameter of AHFinder (Erik)
Message-ID: <3242467.1184920263823.SLOX.WebMail.wwwrun@mailserv.aei.mpg.de>

Hi,

I have steered the parameters AHFinderDirect::find_after_individual[n]
at recovery (to an earlier time, so that at the recovery time it should
havfe already searched for the horizon) and this caused a crash in
AHFinder. Does anyone have experience with this?

The stderr/out says:

INFO (AHFinderDirect): proc 0: searching for horizon 1/3
cactus_belladonna_NoDebug_allThorns:

`jtutil::fuzzy<fp>::NE(r, 0.0)'
failed.

Hi,

  I see this behavior with the 'Erik' tagged version of AHFinderDirect. 
Apparently,
at least for some architectures, if horizon n was never found, then on 
recovery,
the grid function ah_radius[n] will be filled with zeros. It is these 
zeros that trigger
the abort (although I don't understand why they are ever used ... ).
 As a workaround what I do is modify the function
void BH_diagnostics::load(CCTK_ARGUMENTS,  const int horizon_number) in
AHFinderDirect/src/driver/BH_diagnostics.cc
so that it changes a radius of zero to a non-zero value.

Hi Luca,

I think that this problem has been corrected in the latest version in  
CVS.  Do you have version 1.43.2.3 of the file coords.cc?

This version does not have an assert statement in line 313; it is  
commented out.  Did you rebuild the executable?  You can use  
Formaline to check the source which you compiled.

Subject: [Developers] problems compiling cactus on mac osx with ifort
Message-ID: <Pine.LNX.4.64.0707231014260.11125@duo01.aei.mpg.de>

Hi,
 	I have some problems compiling Cactus with the Intel 
fortran compiler on a MacBookPro with Mac OS X version 10.4.9.

I'm using the Intel fortran compiler version 10.0, gcc 4.0.1 and mpich2 
version 1.0.5

 	First of all I had a problem during the configuration since mpich2 
doesn't install tarch. So I have applied a patch that Steve sent one year 
ago to the cactus user ml (I have attached it) and it worked.

But I have still problem. At the end I get the following error:

Creating cactus_Whisky_carpet in /Users/bgiacoma/Cactus/exe from [...]

i686-apple-darwin8-g++-4.0.1: /opt/intel/fc/10.0.016/lib/icrt.link: No 
such file or directory
i686-apple-darwin8-g++-4.0.1: unrecognized option '-Qy'
make[1]: *** [/Users/bgiacoma/Cactus/exe/cactus_Whisky_carpet] Error 1
make: *** [Whisky_carpet] Error 2

Googling for it I found that somebody else had the same problem but I was 
not able to get the solution for it. Any suggestion? I'm using the 
development version of Cactus. The config file I have used is attached.

Thank you,
Bruno

 	I will try your configuration. I'm using Intel since gfortran 
cannot compile some other fortran90 codes I have.

Hi Erik,

I have checked with formaline that I really have the version 1.43.2.3 
and its line 313 reads:

assert( jtutil::fuzzy<fp>::NE(r, 0.0) );


So the problem is still there.

Luca.

I have checked again, and you are right.  This file has several such  
assert statements, and the one I was looking at was in line 399.   
Sorry for the confusion.

I have committed the commenting-out of the other assert statements as  
well.

Yes, this is correct.  The corresponding change to correct this  
(faulty) behaviour requires storing a flag describing whether a  
horizon has been found at some previous time.  This information is  
also interesting for users of the horizon finder, and therefore  
SphericalSurface should also be updated.  We plan to do that in the  
near future, after some careful testing.

In the mean time I have disable the assert statements, so that this  
error should not lead to an abort any more.
