2015-09-02 07:24:49 -0600 asked a question When i run a MPI program,it was right when i use fixed IP of VM,but when i run the program with floating IP,there is something wrong as follows.

Hi Community,

When i run a MPI program with my OpenStack cluster(install with official document), it was right when i use fixed IP of VM,but when i run the program with floating IP,there is something wrong as follows. Is here someone can help me.

When i run program with fixed IP of VM, it runs right,when i run with the floating IP of VM,there is something wrong as follows.

HYDU_sock_connect (./utils/sock/sock.c:203) : unable to connect to "hostname_1" to "hostname_2"(connection refused).

Main(.pm/pmiserv/pmip.c:209) unable to connect to server "hostname_2" at port 39490(check for firewalls!)

I am very confused that the program can run with fixed IP, but can't run with floating IP,is here somthing wrong with my security group rules or other things ? who can help me, thanks!!!

ps:my security group rules. my security group rules

More INFO : My MPI program is runing a Mandelbrot Algorithm, MPI environment is mpich2.

Before I run the program,I have done follows: 1. Define hostnames by editing the file: /etc/hosts 2. Configure ssh for connecting without a password.

my VM is booted from the some image,singal VM is all right(both use floating ip and fixed ip),when i run the program with two or more VM , use fixed IP of VM is all right, but when I use floating IP with VM,the program cause something exception like I described.

Sorry , I have seen your configure file,but I can't find something wrong!!

Could you paste you configure file about nova.conf and nova-compute.conf here on compute node?
2015-08-23 21:51:38 -0600 answered a question Unable to launch instances (Unexpected vif_type=binding failed)

Try to Edit /etc/nova/nova.conf on compute node,and add the follow configuration.

vif_plugging_is_fatal=false
vif_plugging_timeout= 0

Then restart nova-conpute service.

service nova-compute restart
