[petsc-users] out of date warning when petscmpiexec.

[Syvshc]

I still get this warning, I found that "make -q" command won't get any respond.


Here is the whole output:


❯ cd $PETSC_DIR
make -q -f gmakefile libs
echo $?
cd ~/git/p4pdes/c/ch1
make -q e
echo $?
petscmpiexec -n 1 ./e
make clean
make e
make -q e
echo $?
petscmpiexec -n 1 ./e

That's strange. Do you still get this warning from petscmpiexec?

Can you run these commands - and copy/paste the *complete* session from your terminal [for these commands and their output on terminal] ?

>>>>>>
cd $PETSC_DIR
make -q -f gmakefile libs
echo $?
cd bueler/p4pdes
make -q e
echo $?
petscmpiexec -n 1 ./e
make clean
make e
make -q e
echo $?
petscmpiexec -n 1 ./e
<<<<

Alternatively you can just use mpiexec [ i.e not use petscmpiexec - its just a convenience wrapper over using correct mpiexec/valgrind].
