Hi Yanfei,

I tested MPICH with two Raspberry Pis. Now, to crack down the problem faster, i set up Arch Linux on VirtualBox on my Home-PC (1 Node?). Here i tried to execute "mpiexec hostname" and "mpiexec -f machinefile -n 1 hostname", but i still have the problems described in my previous post.

I use/installed ArchLinux 4.10.13-1, base, openssh, nfs-utils, base-devel, sudo, gdb, gcc-6.3.1-2, gcc-fortran, mpich3.1 (On the Raspberry Pis i used 3.2).

I customized access rights, enabled ssh and set up the keys (since i have only one virtual machine i inserted the public key into authorizedkeys), changed locales to germany, enabled autologin by adjusting "/sbin/agetty" and installed MPICH3.1 in my home directory.

My enviroment variables:

LANG=de_DE.UTF-8
XDG_VTNR=1
XDG_SESSION_ID=c1
USER=alarm
PWD=/home/alarm
HOME=/home/alarm
MAIL=/var/spool/mail/alarm
TERM=linux
SHELL=/bin/bash
SHLVL=1
XDG_SEAT=seat0
LOGNAME=alarm
DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus
XDG_RUNTIME_DIR=/run/user/1000
PATH=/home/alarm/mpich-install/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl
_=/usr/bin/printenv

Do you need more information? I also included the output from my installation of MPICH: c2.txt,m.txt and mi.txt.

Hi Lucas,

I just did a quick try on my archlinux box and I could not reproduce the problem. Can you provide more detail about the setup such as the number of nodes in your test? How to environment and environment variable is setup?

Dear mpich,

I experimented with MPICH and followed your install-guide.
I use ArchLinux, SSH and NFS among other things.

After the installation of mpich3.2 i tried to execute the example from your guide: "mpiexec -f machinefile hostname".
The command is executed and the terminal prints the hostname.
But after the use of mpiexec several problems occur.
When I try to use nano, the text editor closes immediately. But beneath the options(Save,help,exit....) it prints "SIGHUB or SIGTERM recived".
When I try to use vi, the text editor prints repeatedly "AT E0F". Im also unable to install applications.
Only after a reboot or exit, and then re-login im able to use a text editor or install an application again.
When i tried the same thing with raspbian it seems to work.
So maybe it could be an ArchLinux specific problem? What could be the problem?

Thank you
Lucas
