[Nek5000-users] Scalability

Hi,

When I am trying to run a big simulation (Nele > 120,000) , on certain
clusters / supercomputers, Nek5000 crashes even though the physical memory
used is very less. 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 ?

Thanks
