First of all, thank you very much for the implementation of MPI support! I
am really forward-looking to use it in future for heavy computing tasks.
However, atm I am experiencing some an issue with the installation on a Win
7 machine. I have installed MS-MPI and set the directory to:
"C:\Program Files\Microsoft MPI\Bin\mpiexec.exe"
but "eval $havempi$" returns zero.
I use current cvs (32-bit) with no admin rights. Could this be a problem?
Best,
Artur

Thanks for testing. I think there may have been an error in the test for
mpiexec.exe on Windows, which could make $havempi fail: can you try with
today's snapshot? (I guess you didn't really type the extra '$' on the end
of $havempi, did you?)

I don't think so but we may have to explore the rights question if it
still doesn't work with the updated snapshot.

No, I didn't.
With current cvs $havempi returns "46" now. But, running the MLE-example of
your MPI-gretl-manual gives the error:
? mpibcast(¶m)
The MPI library is not loaded
Error executing script: halting
mpibcast(¶m)
Actually, example 1 (bootstrap) returns:
Error: while reading machinefile 'C:\Program Files\Microsoft
MPI\Bin\mpiexec.exe': expecting a positive number of cores following the
host name.

OK.
With current cvs $havempi returns "46" now.
46? Hmm, we need to fix that.
But, running the MLE-example of
your MPI-gretl-manual gives the error:
? mpibcast(¶m)
The MPI library is not loaded
That example is intended to be run using gretlcli-mpi. So you have to do
mpiexec /np <number of processes> gretlcli-mpi <script-name>
See section 4.2 of the "Gretl/MPI Q & A". If you don't want to do that,
wrap the whole script in "mpi ... end mpi <options>".
Actually, example 1 (bootstrap) returns:
Error: while reading machinefile 'C:\Program Files\Microsoft
MPI\Bin\mpiexec.exe': expecting a positive number of cores following the
host name.
It looks as if you have entered the path to mpiexec.exe as your MPI hosts
file (under Preferences/MPI). That's not right, please see section 4.1 of
the notes, "Establishing a hosts file". But if you're running on a single
machine you don't need (or want) a hosts file, just blank that out in the
GUI preferences.

I still have to try this. Starting "gretlcli-mpi.exe" demanded
admin-rights (firewall problem), which I don't have here atm.

Ok, I left the host-file path blank, and it works now! But, only the
admin-rights
gretl version correctly recognizes the MPI library. But this
may be due to the fact that I store the no-admin version in my personal
folder, but not in "C:\Program Files\gretl" directly. The error message
just states that the system cannot find the file (in GER: "Das System kann
die angegebene Datei nicht finden.")
