Fande,
Did you try set TMPDIR for valgrind?

Thank you!
It makes sense to use share/petsc/Makefile.user - I will try to understand it.
However, can you please tell me what is the meaning of "_SINGLE" in
"PETSC_COMPILE_SINGLE"? Does it mean compile only one source file?
Best regards,
Alex Koshkarov.

Thanks so much, Satish,

Hi All,
I have been using trivial makefile (see below) for the code which uses petsc.
The makefile relies on variable PETSC_COMPILE which disappeared in new petsc
version (absent in 3.14.2, but present in 3.13.4). What would be the right way
to fix the makefile? (should I use something like
Its internal organization of some old code.
Previously we had 2 things:
- PETSC_COMPILE (perhaps PETSC_COMPILE_MULTIPLE is a more appropriate name) did
something equivalent to 'gcc -c a.c b.c c.c' - i.e compile multiple files at
the same time.
- PETSC_COMPILE_SINGLE used was to compile one
For one - I think using '--log-file=valgrind-%q{HOSTNAME}-%p.log' might help
[to keep the logs from each process separate]
And I think the TMPDIR recommendation is to have a different value for each of
the nodes [where the "pid" clash comes from] and perhaps "TMPDIR=/tmp" might
work - as this
Hello everyone,
So far, I have the wrappers in the files attached to this e-mail. I still
do not know if they work properly - at least the code compiles and the
calls to the wrapped-subroutine do not fail - but I wanted to put this here
in case someone sees something really wrong with it already.
This is great. If you make a branch off of the PETSc git repository with
these additions and work on ex11 you can make a merge request and we can run
the code easily on all our test systems (for security reasons one of use needs
to launch the tests from your MR).
Alex,
Since you are explicitly defining your rules you might as well just do it
completely, so use something like
>> objects/%.o: src/%.c $(DEP)
>>${PCC} -c $< -o $@ ${PCC_FLAGS} ${PFLAGS} ${CCPPFLAGS}
The P indicates either C and C flags or C++ compiler and its flags if
Hello everyone,
Thank you Barry for the feedback.
OK, yes I'll work up an MR as soon as I have got something working. By the
way, does the fortran-version of the example have to be a single file ? If
my push contains a directory with several files (different modules and the
main), and the

I don't want it
Thibault,
A subdirectory for the example is fine; we have other examples that use
subdirectories and multiple files.
Note: even if you don't have something completely working you can still make
MR and list it as DRAFT request for comments, some other PETSc members who
understand the
No idea. Perhaps petscmpiexec could be modified so it only ran valgrind on
the first 10 ranks? Not clear how to do that. Or valgrind should get a MR that
removes this small arbitrary limitation on the number of processes. 576 is so
2000 :-)
