Comment (by hinder):

 If you increase the number of grid points, this increases the amount of
 memory needed for the run.  Is your run terminating because it runs out of
 memory?  If you can run "top" on the node, you should see if this is
 happening.  You can also activate the thorn SystemStatistics and add the
 following into your parameter file to get output of the memory usage
 ("maxrss"):

 {{{
 IOBasic::outInfo_reductions             = "maximum"
 IOBasic::outInfo_vars                   = "SystemStatistics::maxrss_mb
 SystemStatistics::swap_used_mb"
 }}}

 This will add two new columns to the info output: the memory used by the
 process, and the swap space allocated, in MB.  You can then compare this
 to the memory available on the node, and see if there is swapping.

 Can you provide the standard output and standard error files so we can see
 what is happening?
