Hello.<br><br>We (the Illinois group) need an elliptic solver in Cactus. Thus far, we have found that with our version of Cactus+AEIThorns (latest publicly available CVS from cactuscode.org and cvs.aei.mpg.de) neither BAM_Elliptic nor EllPETSc will work properly. Ideally, we would like to use either.<br><br>I've detailed our problems with these two thorns in the below sections.<br><br>-= BAM_Elliptic Problems =-<br>BAM_Elliptic compiles just fine, but when I try to run it, it gives:<br>WARNING level 0 in thorn BAM_Elliptic processor 0<br> (line 294 of /.../Cactus/configs/.../build/BAM_Elliptic/Cactus4_utils.c): <br> -> BAM requires PUGH::processor_topology to be set to "manual" or "automatic_old"<br>When I do what the warning suggests, I get a segfault (when attempting to set the topology to manual) or "Range error setting parameter 'PUGH::processor_topology' to 'automatic_old'" (when attempting to set the topology to automatic_old). Looking
at the source code, I conclude that this problem appears to be caused by a bugfix inside BAM_Elliptic/src/Cactus4_utils.c. <br><br>Cry for help:<br>Does anyone have a version of BAM_Elliptic that does not have this issue with the latest PUGH?<br><br>-= EllPETSc Problems =-<br>Apparently the PETSc API has changed since the current CVS version of EllPETSc was written. With the latest version of PETSc (petsc-2.3.2-p8), EllPETSc will not even compile, giving the error:<br>/.../Cactus/configs/.../build/EllPETSc/petsc_confmetric_solver.c(1046): error #165: too few arguments in function call<br> ierr = SLESSolve(sles,b,soln,&its); CHKERRQ(ierr);<br><br>Cry for help:<br>Does anyone have a version of EllPETSc that works with the latest version of Cactus? At the very least, does anyone know what version of PETSc EllPETSc was designed to work with?<br><br>Thanks for your reply.<br><br>-Zach Etienne, on behalf of the Illinois
