Hi Shriram,

what happens if Nek is going to crash. Any chance to post a logfile?
What the static size of your Nek executable (e.g. size nek5000)?

For example, on certain machines, with Nele = 120,000, we couldn't go more than lx1 of 7 while on different architecture we could go up to lx1 = 12. Is this issue concerned with compilers or the architecture of the machine ?
