OpenMosix Debian mini HOWTO

  version 0.2
  Malix Ren

    I have a box of MMX166 and a thinkpad T22(PIII 900), both with Debian Woody installed.Here is a short description for playing with openmosix.

1. install mosix package, because I need the /etc/mosix.map and /etc/init.d/mosix and etc.(now there is yet no corresponding deb files for openmosix );
2. patch and recompile the kernel with your willing.
   I have used make-kpkg(in packages "kernel-packages") to make new kernel-image package, thus can i install it to every machine;
3. /etc/hosts:
   192.168.100.101 mosix_1
   192.168.100.102 mosix_2
4. /etc/mosix.map
   1 mosix_1 1
   2 mosix_2 2
5. in mosix_1 :
   ifconfig eth:0 192.168.100.101 netmask 255.255.255.0
   Actually I have 2 3COM 905B net card in MMX166 installed, as it serves as my Web Server and NAT Gateway for T22. So I configured it in my /etc/network/interfaces like this: 
            auto eth1 iface eth1 inet static
            address 192.168.100.101
            netmask 255.255.255.0
            network 192.168.100.0
            broadcast 192.168.200.255
           
          in mosix_2 :
                ifconfig eth:0 192.168.100.102 netmask 255.255.255.0
          in /etc/network/interfaces :
            auto eth0
            iface eth0 inet static
            address 192.168.100.102
            netmask 255.255.255.0
            network 192.168.100.0
            broadcast 192.168.100.255
            gateway 192.168.100.101


6. both box must have the /etc/hosts and /etc/mosix.map
7. Since I used the eth1 for mosix_1, so it is not the default net enviroment for mosix. It is needed to:
   #cat 1 > /etc/mosix/mospe
   
this is needed for "setpe -p" option, and the detail information is in "man setpe".

8. test:
    #awk 'BEGIN {for(i=0;i<10000;i++)for(j=0;j<10000;j++);}
    this will migrate.
    #awk 'BEGIN {for(i=0;i<10000;i++)for(j=0;j<10000;j++)print i,j;}
    this will not migrate,bcause of stdout used.
    #awk 'BEGIN {for(i=0;i<10000;i++)for(j=0;j<10000;j++)c=i+j;  print c;}
    calculation will migrate, and the result will back to the original box.

hope it will help.
