> Dear Nek users,
> Currently, I am working on a simulation with a decent size (11760 * 12 elements) employing ‘lpmin = 32’. When I compile, I received an error saying: “relocation overflows omitted from the output”.  I googled this
>  error and it turned out this error comes from the ‘COMMON’ block;  Static data, such as COMMON variables, and all of the code together is still limited to 2GB under any mcmodel.  The suggested solution is to  move
>  the data out of a COMMON block and into a module and make the data allocatable. 
> The most straightforward way to avoid this would be increase the ‘lpmin’ (for example if lpmin = 64, then it works), but this does not solve this issue, which is a
>  big constraint. I am wondering has anyone has run into this and got any experience in solving it?
> Thanks a lot in advance
