Yes, you are right. The error is this:
pp2@europa:~/LGRID-Machine/examples/matrixproduct/open2$ ./matrix_grid
+.pl
Can't open perl script "/tmp/gridmachine_driver_matrixZNJuj": No such
+file or directory

If I uncomment the sleep in
pp2@europa:~/LGRID-Machine/examples/matrixproduct/open2$ sed -ne '153,
+168p' matrix_grid.pl
foreach (@str_handles) {
my $pid = $pm->start and next;
$b = syswrite $_->{handle},
join(" ",
$_->{chunksize},
$_->{A_cols},
@A_lines[$_->{start}.. $_->{end}],
@B_lines,
"\cN"
);
# Wait until the writing has finished
# sleep(1);
$pm->finish;
}
It goes OK:
pp2@europa:~/LGRID-Machine/examples/matrixproduct/open2$ ./matrix_grid

Process 0: machine = bw received result
Process 1: machine = beowulf received result

I know is still very cryptic. Apologies.
