SGE backend: can not connect to the front-end node

[GoogleCodeExporter]

Hello,

I wanted to use GC3Pie to run an application on AWS cloud. The computing 
resources I want to used is a SGE cluster mounted on AWS-EC2 platform.

I managed to mount an SGE cluster on AWS (usin g an external tool). Using the 
GNU linux ssh-client, I can log-in to the front-end node:
ssh -i ~/.ssh/aws-cluster.rsa sgeadmin@ec2-23-23-33-153.compute-1.amazonaws.com

Unfortunately, when running my script, it says that it can not connect to the 
front-end node: TransportError: Failed while connecting to remote host 
'ec2-23-23-33-153.compute-1.amazonaws.com': 'int' object is not iterable. 
The detailed log file is attached.

My config file is :
[auth/sshgordias]
type=ssh
username=sgeadmin
keypair_name=aws-cluster.rsa

[resource/gordias]
enabled = true
type = sge
auth = sshgordias
transport = ssh
frontend = ec2-23-23-33-153.compute-1.amazonaws.com
architecture = x86_64
max_cores = 20
max_cores_per_job = 1
max_memory_per_core = 1
max_walltime = 8
qstat = /usr/local/bin/qstat
qacct = /usr/local/sbin/qacct.sh
qdel = /usr/local/bin/qdel
keypair_name=aws-cluster.rsa

Could you please help me to localize the issue?
Thanks in advance.

Mohamed

Dear Mohamed,

this bug has been fixed in SVN r3871.  The fix is, however, only in the "trunk"
development release.  I'm working towards making a 2.2.0 release from the code
currently in "trunk".

Thanks,
Riccardo

Dear Mohamed,

I have just released GC3Pie 2.2.0.  Could you
please test it and tell us if it works?

Thanks,
Riccardo

Dear Riccardo,

Perfect, It works :). I also used 'elasticluster'  which I find it a great
tool.
I used 'elasticluster' to mount a SLURM cluster (using ubuntu 12.04 LTS
ami) on AWS and  GC3Pie scaled well on it.

Many thanks for your help !

Mohamed
