And is edge weights being less than 10 still valid? Although I am not
getting any errors, when the elements in my matrix are larger than 10, even
ParMETIS doesn't give different results.

Hi all,
I am trying to partition a sparse matrix by using ParMETIS. I am converting
my matrix to adjacency type and then applying partitioning. Default, I
understood that partitioning doesn't use edge-weights. However, when I used
the following codes I saw from ex15 and used

> eigenvector vr (of size 2n) in paralle
Hello,
I am trying to permute a matrix A(of size 2n*2n) according to a sorted
eigenvector vr (of size 2n) in parallel using 2 processors (processor
number can change). However, I get an error in MatPermute line stating that
arguments are out of range and a new nonzero caused a malloc even if I
end in a small example that we can debug.

Hello,
I wrote a code computing element wise absolute value of a matrix. When I
run the code sequentially, it works. However, when I try to use it in
parallel with the same matrix, I get the following error:
[1]PETSC ERROR: Argument out of range
[1]PETSC ERROR: Only local rows
The absolute
Hello,
I am trying to compile a parallel program DENEME_TEMIZ_ENYENI_FINAL.c in
PETSc. I wrote the following makefile but it says that there is nothing to
do with the program:
export CLINKER = gcc
DENEME_TEMIZ_ENYENI_FINAL: DENEME_TEMIZ_ENYENI_FINAL.o chkopts
-${CLINKER} -o
Dear Professor Roman,
I decided to install petsc-3.10.3 with slepc since I did it once
succesfully. Thanks for your help.

This is slepc.log:

Hello,
I am trying to install PETSc with following configure options:
./configure --download-openmpi --download-openblas --download-slepc
--download-cmake --download-metis --download-parmetis
Compilation is done but after the following command, I got an error:

Hello,
I have a Laplacian matrix PL of matrix A and I try to partition A using
PARMETIS. Since PL is sequential and not adjacency matrix, I converted PL
to AL, then write the following code:
ierr = MatConvert(PL,MATMPIADJ,MAT_INITIAL_MATRIX,);CHKERRQ(ierr);
ierr =
in
/home/edaoktay/petsc-3.10.3/arch-linux2-c-debug/externalpackages/git.slepc/src/eps/interface/epssolve.c
I understood from this error that the matrix does not converge. However, I
tested in MATLAB and it converges. The matrix is true now, so this cannot
be from the matrix.
Thanks,

Dear Matt,
I printed in wrong state, ncols gives right solution.
But I still can't understand the first problem.

Hello,
I have a following part of a code which tries to change the nonzero values
of matrix L with -1. However in MatSetValues line, something happens and
some of the values in matrix turns into 1.99665e-314 instead of -1. Type of
arr is defined as PetscScalar and arr is produced correctly. What

Hello,
I have a code finding Laplacian of a matrix and then I need to find this
Laplacian's second smallest eigenpair. I used EPSGetEigenpair code but I
get the values like "0." or "4." (I could not get decimals) when I used
PetscPrintf(PETSC_COMM_WORLD," The second smallest eigenvalue: %g\n",kr)
; easy way is to read them into Matlab with mmread.m and write with PETSc's

Hello,
I am trying to use MatTranspose function as in below (last row) but I get
an error like this:
[0]PETSC ERROR: - Error Message
--
[0]PETSC ERROR: Object is in wrong state
[0]PETSC ERROR: Not for unassembled
ite? Does this for loop give me these 3 arrays (arrays consist
of row indices,column indices and values)?
