OK, thanks.
Hm, I'm not getting very far, see the following error output for an
empty mpi block, the error message says "invalid option '--np'":
<scriptoutput>
gretl-Version 1.10.0cvs
Aktuelle Sitzung: 2015-02-16 15:34
? bundle sb = $sysinfo
? scalar gmpi = sb.mpi
Erzeugte Skalar gmpi = 1
? print gmpi
gmpi = 1.0000000
? mpi
? end mpi --np=2
ungültige Option '--np'
Fehler bei Skriptausführung: Stopp
end mpi --np=2
</scriptoutput>
This is on 64bit Win7 with latest gretl snapshot, and I installed
Microsoft's MPI and entered the path in the gretl MPI settings. The
output from $sysinfo.mpi seems to indicate that gretl found the MPI
stuff ok.
And BTW, if I rerun the script after this error, then I get another error:
"? mpi
foreign: a block is already started"
which reminds me of earlier times when gretl wasn't always recovering
cleanly from execution interrupts.
thanks,
