[Users] changing CarpetRegrid2 parameters for ETK Maxwell + mercurial Carpet?

[Bernard Kelly]

Hi all (again).

I mailed the ETK list back in November (!) because of a problem with our 
BHB evolutions using ETK "Maxwell"; said evolutions crashed after only a 
few M of evolution. Erik made some suggestions, I supplied more 
diagnostic information (output_bboxes=yes), Erik looked it over again, 
and suggested a further diagnostic message to nail down what the problem 
was.

I thought I was doing this, when the problem magically disappeared, so I
didn't get back to the list.

Unfortunately, it turned out that what had happened was I accidentally
went back to ETK "Curie" (and hence my older, non-crashing problem).
["Accidentally" here means I was led astray by some symbolic links I
created to point to our own Hahndol thorns within the Cactus 
arrangements directory.] Now that I've discovered my own stupidity, I 
still need ysome help. I've implemented Erik's suggested diagnostic 
message in CarpetLib. Here's my new code, inserted at
line 948 of the repository CarpetLib/src/dh.cc:

--------------------------------------------------------------
948,954d947
<          /* [2011-11-21] diagnostic code suggested by Erik */
<          if (not(needrecv.empty())) {
<            cout << "rl=" << rl << " c=" << c << " needrecv=" << needrecv
<< endl;
<            CCTK_VWarn (1, __LINE__, __FILE__, CCTK_THORNSTRING, "rl=%d,
c=%d, needrecv=%d\n",rl,c,needrecv);
<          }
<          /* end of diagnostic code */
--------------------------------------------------------------


I've run both with and without ouput_bboxes, in a relatively 
low-resolution run. I've again put the screen output files on webdrive 
again, along with the source parameter file. Here's the URL to access it:

https://webdrive.gsfc.nasa.gov/longauth/600/bernard.j.kelly/QSDKYC3

As before, you'll need the temporary username (beanykelly) and password 
(helpmercurial).

Thanks in advance -- again -- for your help,

Bernard
