Thank you Matt and Samar,
Seems the segfaults I see are related to icc, which is not being updated
anymore. The recommended intel C compiler is icx which is not released for
Macs. I compiled the lib with gcc 13 + openmpi from homebrew and the tests are
passing just fine in optimized mode. I
Hi Marcos,
Yes, I compiled with clang instead of icc (no particular reason for this; I
tend to use gcc/clang). I use mpich4.1.1, which I first built with clang and
ifort:
FC=ifort
./configure --prefix=/usr/local/mpich4 --enable-two-level-namespace

Hi Samar, what MPI library do you use? Did you compile it with clang instead of
icc?
Thanks,

Hi, for what it’s worth, clang + ifort from OneAPI 2023 update 1 works fine for
me on both Intel and M2 Macs. So it might just be a matter of upgrading.

Hi Satish, yes the -m64 flag tells the compilers the target cpu is intel 64.
The only reason I'm trying to get PETSc working with intel is that the bundles
for the software we release use Intel compilers for Linux, Mac and Windows
(OneAPI intelMPI for linux and Windows, OpenMPI compiled with

Hi Matt, I configured the lib like this:
$ ./configure --with-blaslapack-dir=/opt/intel/oneapi/mkl/2022.2.1
--with-debugging=0 --with-shared-libraries=0 --download-make
and compiled. I still get some check segfault error. See below:
$ make PETSC_DIR=/Users/mnv/Documents/Software/petsc-3.19.1
Ops - for some reason I assumed this build is on Mac M1. [likely due to the
usage of '-m64' - that was strange]..
But yeah - our general usage on Mac is with xcode/clang and brew gfortran (on
both Intel and ARM CPUs) - and unless you need Intel compilers for specific
needs - clang/gfortran
Hi Satish, well turns out this is not an M1 Mac, it is an older Intel Mac
(2019).
I'm trying to get a local computer to do development and tests, but I also have
access to linux clusters with GPU which we plan to go to next.
Thanks for the suggestion, I might also try compiling a gcc/gfortran
Thank you Matt I'll try this and let you know.

On Mon, May
I see Intel compilers here are building x86_64 binaries - that get run on the
Arm M1 CPU - perhaps there are issues here with this mode of usage..

Hello, I'm trying to compile the PETSc library version 3.19.1 with OpenMPI
4.1.4 and the OneAPI 2022 Update 2 Intel Compiler suite on a Mac with OSX
Ventura 13.3.1.
I can compile PETSc in debug mode with this configure and make lines. I can run
the PETSC tests, which seem fine.
When I compile
BDDC is a domain decomposition solver of the non-overlapping type and
cannot be used on assembled operators.
If you want to use it, you need to restructure your code a bit.
I presume from your message that your current approach is
1) generate_assembled_csr
2) decompose_csr? or decompose_mesh?
3)
Hello sir,
I am a PhD student and am trying to use the PCBDDC method in petsc to solve
the matrix, but the final result is wrong. So I would like to ask you a few
questions.
First I will describe the flow of my code, I first used the finite element
method to build the total matrix in CSR format
