[Gretl-devel] Re: feval and MPI

Hi,
another MPI question or issue: Is the relatively new 'feval' meta-style
function supported inside MPI? (Of course using the --send-functions
option.)
OK, I have established that it does work when a native (gretl builtin)
function is called. However, with a user-defined function it seems to
fail, as in this example:
<hansl>
nproc = 1
function scalar mpifevaltest(void)
return $pi
end function
mpi --send-functions
scalar x = feval("mpifevaltest")
mpireduce(&x, "sum")
if $mpirank==0
print x
endif
end mpi --np=nproc
</hansl>
This is on 2019d on Windows.
thanks
