Would you mind providing the parfile bnstest.par that you are running,<br>
please? It does not seem to exist in the Einstein Toolkit repos and<br>
without it all we can do is guess what could be happening.<br>
<br>
The string "Read.*expected" also does not seem to show up anywhere in<br>
my Cactus tree (or any of my executables for that matter), so that I am<br>
not sure at all which thorn or module is even generating this error.<br>
<br>
The string does however show up in libgfortran.so so that I would guess<br>
that it is some Fortran code not checking if it could open a file<br>
correctly. <br>
<br>
You can try running what looks like an address: 83bdcfc58a2e through<br>
the addr2line command:<br>
<br>
addr2line -e /home/zhaozc/simulations/bnstest/SIMFACTORY/exe/cactus_sim<br>
0x83bdcfc58a2e<br>
<br>
or use gdb:<br>
<br>
gdb /home/zhaozc/simulations/bnstest/SIMFACTORY/exe/cactus_sim<br>
info line *0x83bdcfc58a2e<br>
<br>
to try and find out which thorn was responsible, though I cannot<br>
guarantee that this will work.<br>
<br>
A blind guess would be that some thorn fails to open a file, does not<br>
properly check for this and then find that it cannot read anything from<br>
that (not opened file) in which case eg the read() system call returns<br>
-1.<br>
<br>
Yours,<br>
Roland<br>
