Obviously, holistic support for OpenMP is critical to the future of PETSc :-D On a more serious note, Matt and I have discussed the use of PETSc for sparse multidimensional array computations for dimensions greater than 2, also known as tensor computations. The associated paper describing previous

2016-07-01 Thread Barry Smith
The DOE SciDAC institutes have supported PETSc linear solver research/code development for the past fifteen years. This email is to solicit ideas for linear solver research/code development work for the next round of SciDAC institutes (which will be a 4 year period) in PETSc. Please se

No idea. You need to do what it says and run with valgrind or in a debugger. From the crash message it looks like it is crashing in your main program. Barry > On Jul 1, 2016, at 1:26 PM, 张江 wrote: > > Hi, > > I am trying to read a large data (11.7GB) with libmesh (integrated with > PET

Hi, I am trying to read a large data (11.7GB) with libmesh (integrated with PETSc) and use it for my application. The program runs well when using just one process. But in parallel (mpirun -n 4), some errors came out: [0]PETSC ERROR:
