[Nek5000-users] Compilation error

[nek5000-users at lists.mcs.anl.gov]

Dear Jean-Christophe,

etime is a fairly std. timer function, but obviously not
supported with your compiler.

When using mpi, it uses instead the mpi timer, so there is no
issue.

The quick fix here would be to edit mpi_dummy.f and change
the etime() reference therein to the ibm timer function.

You might also try setting it zero - but I'm not 100% certain
that there are no divisions involving time in the denominator...
It's worth a try, however.

Paul
