<DIV></DIV>Hi Gus,<BR><BR>I thought to something similar, and modify/increase
the dimension of the buffer for mpi. But this didn't solve the problem.
Moreover, I had the same problem on my PC at home, and on a two CPU system at
the University, where there are 16GB of memory.<BR><BR>Moreover, in both the
configuration the simulation work once I have restarted mpd after the boot and
also using mpd not launched at boot time (with root privileges) but started by
the user before running the simulation.<BR>Note that also running mpd
after the bot with root privileges results in a correct behavior of the
code.<BR><BR>I really don't know: it seems something relevant to the boot-time
startup.<BR>For the moment, I use the solution of mpd launched by the user,
but the one with mpd started by the root at boot time is more 'elegant'.
