Dear all I have a large matrix in a text file which I am trying to convert and save in PETSc binary format. However I run into some strange MPI errors when I try to save the matrix.
I have created a minimal example file to reproduce my problem. I ran it with #PBS -l pmem=16GB #PBS -l select=8:mpiprocs=1:ncpus=1 #PBS -l place=excl:scatter and it crashed when writing the file to disk. Note that if I use smaller values of m in the code then it works reliably. My PETSc installation is compiled with --with-64-bit-indices and I took care to ensure that all arguments to PETSc functions are PetscInt wherever appropriate. Please find code, output, and configure.log attached. Any pointers on what is going wrong are deeply appreciated. thanks vishy -------------- next part -------------- A non-text attachment was scrubbed...
