I got a problem with /ksp/ksp/example/tutorial. I was trying to execute this example with petsc-dev in a share memory dell workstation with 8 cores. The parameter for DMDACreate2d is 500, 500, which means it generates a 1997*1997 2d grid. It is fine to run it with single process with either "./ex29" or "mpiexec -np 1 ./exe29". However, it came across a error when I tempted to run it with more than 1 process. The error message is like this, when I was trying to execute it with 4 processes. I was thinking about if the 'stack size' is the problem, so I enlarge it to 1000000000 with 'ulimit' command. However, the same error message keeps showing up.</blockquote>
