Intel Paralel Studio xe 2017 - Cluster Edition Installation problem

 

I got Intel Parallel Studio trial version to run on my linux nodes (I have two nodes currently). During the installation I am facing two issues.

1. It says "Login Failed - due to ssh issue"

I have ssh up and running and I have registered and copied the keys and using ssh "IP" I can easily login to the remote server. 

2. Invalid cluster description file

Though I have created "machines.LINUX" in the same directory where install.sh is located yet it shows the same error.

 

Is the invalid cluster file error caused due to the ssh issue or is it something else.

 

Any help in this regard will be appreciated.

 

Thanks

Hi Shoaib,

Please can you provide some more information:

Please let me know the command line you are using. Do you install as normal user or as root (e.g. via sudo)?

Do your nodes share a common file system?

I understand you have setup password-less ssh by using keys. Does the following work:
sh -c 'for host in $(cat machines.LINUX); do ssh $host hostname; done'

Best regards
Klaus-Dieter

Hi Klaus,

I generated ssh keys and copied them on the nodes using the following commands.

  • ssh-keygen -t rsa
  • ssh-copy-id IPAddress_of_the_node

After that I simply run the install.sh from the download directory. The machines.LINUX file resides in the same directory and has the following content ....

master

slave

where master is the hostname of node1 and slave for the node2. It reads the number of nodes correctly but later (after I enter the installation directory) it prompts with an error saying

I have tried doing it both as a root and a normal user. Moreover when I run the graphical installation (install_GUI.sh)

It says

 

1. Login failed (ssh command)

2. Invalid Cluster Description File

Please test the command:
sh -c 'for host in $(cat machines.LINUX); do ssh $host hostname; done'

It should work without providing a password, right?
