Re: [vizstack-users] Configuring VizStack - vs-generate-node-config Problem

[Kumar, S. <shr...@hp...>]

Hi Cristi, 

I appreciate you trying VizStack.

xserver-xorg package is necessary to use VizStack. I believe it is installed already on your system.

The issue you see has been fixed, but is not yet part of a release.

http://sourceforge.net/apps/trac/vizstack/changeset/339

If you apply the above mentioned change on all your node(s), then the configuration must proceed normally.

Let me know if that does not fix it!

Cheers

Subject: Re: [vizstack-users] Configuring VizStack - vs-generate-node-config Problem

Hello again,

    Unfortunately it doesn't work like this - either with:

# /opt/vizstack/sbin/vs-configure-system -s slurm node[1-4]

or

# /opt/vizstack/sbin/vs-configure-standalone  - on the master node(with GPU)


I received the same result:

Do you have other solutions ? I am using vistack_1.1-3_ubuntu9.10.amb64.deb

Thank you in advance.

Hello,

    Can you try running the script excluding the Master Node without GPU. For example if node5 is the master node, can you try with

# /opt/vizstack/sbin/vs-configure-system -s slurm node[1-4]
