I am getting an "INFOG(1) = -51 integer overflow" error from Mumps<br>
because the linear system I am solving is very big. I have tried to<br>
configure Mumps in a full 64-bit integer version using<br>
<br>
===============================================<br>
<br>
./configure --with-64-bit-indices --with-cc=gcc --with-cxx=g++<br>
--with-fc=gfortran --with-debugging=0 COPTFLAGS='-O3 -march=native<br>
-mtune=native' CXXOPTFLAGS='-O3 -march=native -mtune=native'<br>
FOPTFLAGS='-O3 -march=native -mtune=native' --download-fblaslapack<br>
--download-openmpi --download-scalapack --download-mumps<br>
--download-metis --download-suitesparse --download-parmetis<br>
<br>
===============================================<br>
<br>
but I obtain the following error:<br>
<br>
*******************************************************************************<br>
UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details):<br>
-------------------------------------------------------------------------------<br>
Cannot use MUMPS with 64 bit integers, it is not coded for this capability<br>
*******************************************************************************<br>
<br>
Is there a way to use Mumps with 64-bit integers through Petsc? or to<br>
use the "selective 64-bit integer feature"?<br>
<br>
Thank you ahead.<br>
