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?
