Can't form mpi ring -

I have a problem with configuring and running MPI on my system

Here I The one who tried it:

1) I did 'M.D. & amp; On one machine and then I run 'MPdtrue-L' on the same machine. I found this as an output: "my-lappy_53430 (127.0.1.1)"
2) On the second machine I got 'MPD-H-P53430 and' and got this error:

 akshey- Desktop_39993: conn error in connect_lhs: connection timed out akshey-desktop_39993 (connect_lhs 924): 10.2.28.137 52430 failed to connect to lhs akshey-desktop_39993 (enter_ring 879): Lhs connect failed akshey-desktop_39993 (267 runs) : Failed to enter the ring 

Can you please help with this problem? I tried to do Ping and SSH's first machine (which is running MPD) from another machine and it worked.

After this I performed the 'mpdheck' on the first machine, I got this output:

 * * * The first ipad (hosted through my lap) for this host is: 127.0 .1.1 

This is the content of / etc / hosts for the first machine:

<127x1.1 localhost 127.0.1.1 MyLappi # The following lines are desirable for IPv6 enabled hosts: : 1 localhost IP6-localhost IP6-loopback FAGX :: 0 IP6 -Nonnet FFX :: 0 IP6-MCCPriff IFF 02 :: 1 Ip6-allnodes ff02 :: 2 ip6-allrouters ff02 :: 3 ip6-allhosts

Then I ran 'mpdcheck -l' and got it as output:

 ***** ***** Fixes your ineligible hostname 127.0.0.1, which is the IP address reserved for localhost. This means that you have the same line in your / etc / hosts file: 127.0.0.1 $ uqhn This might be changed to the following: 127.0.0.1 localhost.localdomain localhost ********* * 

Even after changing the first line of / etc / hosts for "127.0.0.1 localhost.localdomain localhost" I still got the same output from 'mpdcheck -l'

please Note that I do not have access to the network's DNS server and these machines have no DNS entry in the DNS server Is. (I think that this should not be a problem because we can always use the IP address instead of hostname. Is not it?)

two points:

1. You probably do not want to wire an MPD ring by hand. Unless you are troubleshooting something with a raw mpd command, you probably want to use mpdboot is described in its use.
2. Since you are using MPD, you are using MPICH2 or MPICH2 derivative. Starting with MPIT 1.1, a new process manager is available, called "". I encourage you to update to the latest version of MPIT 2, which you can give and try to hydra. It is much stronger than MPD and has many features, including better performance.
