Hello LAM,

I have just tried LAM 5.6.9 patched with `the' path
which fixes a bug in `tkill.c' encountred on dikless computer
( http://www.lam-mpi.org/MailArchives/lam/msg05820.php )
with a hello-like program `phello' (see attachement).

the following procedure works fine:
1] lamboot ; lamhalt ;

This one
2] lamboot ; mpirun -n 10 phello; lamhalt;
works when the number of processor is greater than one,
oterwise I get the message:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
lam_deregister_object (name):
Warning: No such file or directory: deleting shared memory id's from
registry
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

but if I launch phello twice, LAM stucks the second time:
lamboot ; mpirun -n 10 phello; mpirun -n 10 phello; .......

If I do `lamclean' between the `mpirun' calls,
evrything works (when the number of processor is greater than one,
I get the same error message as before).

I hope that helps,
Jerome
