See http://wiki.mpich.org/mpich/index.php/Using_the_Hydra_Process_Manager for how to launch MPI across multiple machines. You do not need to use any special hardware adapter; any Ethernet card should provide sufficient TCP/IP support. Jeff On Tue, Oct 22, 2013 at 9:23 AM, Pavan Balaji <[email protected]> wrote:

Hello,

You'll need to either install mpich on a shared file system (such as NFS) or individually on each of the nodes. The README file in the mpich tarball should have most of this information.

Hi,

I did some experimentation with MPICH on windows, and recently came to know that there is no support for Windows now. I am now shifting to Ubuntu. I was successful in installing MPICH2 and running my first MPI program on a single machine.

Now I want to run my code on multiple PCs. How do I install MPI in a LAN ? What are the additional requirement if any? Do I need any specific hardware -network adapter My card details are as under:

root@ubuntu:/home# lspci -nnk | grep -i net -A2 01:07.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ [10ec:8139] (rev 10) Subsystem: Hewlett-Packard Company Device [103c:301d] Kernel driver in use: 8139too

Most of my machines are having this type of card and are connected in LAN. Really appreciate for any pointers to appropriate document or suggestions.

Thanks and regards,
