Hi,
I have installed a local copy of Intel Parallel Studio for a local machine easily using the install GUI (install_GUI.sh). It is working for that local machine properly.
Then I decided try to Install it with Cluster Option. I have two Ubuntu (14.04.1) Linux machine. I tried what is proposed in the Guide (https://software.intel.com/sites/default/files/managed/b6/26/Install_Gui...). But sshconnectivity script does not work.
machine.LINUX file contains:
#cluster nodes
#****************************
# master node
# cahitarf (argefiz04)
# hostIP: 10.7.3.174
Fizik-bilg04-Linux
#----------------------------
# computing nodes
# azizsancar (argefiz03)
# hostIP: 10.7.3.173
sancar-linux
The output of the script is below. (./sshconnectivity.exp machine.LINUX)
nubagamma@Fizik-bilg04-Linux:~/Desktop/intel_compilers/parallel_studio_xe_2016_update1$ ./sshconnectivity.exp ../machines.LINUX

Then I learned that Intel P. Studio only needs a passwordless ssh connectivity between cluster nodes. I did manually and test it manually everything is OK. But I get the following error from install_GUI.sh
Login failed
The following nodes are not accessible using the ssh command:
Fizik-bilg04-Linux sancar-linux
Installation will proceed with only the accessible nodes.Invalid cluster description file
File /home/nubagamma/Desktop/intel_compilers/machines.LINUX does not contain accessible nodes. Please check your cluster description file.
What I am doing wrong?
Any help, I will be very appreciated.
