Add a server/host to Aster Study

francoisg

Hi all,

Following french ANSSI security recommendations, ssh localhost is disabled on our workstations. Only dedicated computation servers can be ssh'ed to. How do I add those servers/hosts to Aster Study GUI ? The combobox is limited to 'localhost'.

Thanks,

François.

I found the answer, so I'll reply to my post for the record.

Machines available in AsterStudy GUI are declared in Salome, in an XML file named CatalogResources.xml located in the Salome application folder, e.g.

salome-meca/appli_V2018/CatalogResources.xml

There is no CatalogResources.xml file after installation and creation of appli_V2018 folder (bug or feature ?). There is a minimal file located somewhere in the salome-meca distribution which contains the definition for localhost machine. You can copy and edit this file. It seems that there is a python script to build the CatalogResources.xml file but I could not execute it successfully. Anyway, the resources must be declared as follows :

...

hostname="remote_machine_hostname"

protocol="ssh"

appliPath="/path/to/salome-meca/appli_V2018"

canLaunchBatchJobs="true" />

One must be able to ssh to remote machine without prompt for password. The path to salome binary stated in the XML file must be the path on the remote machine.

Hello,

Note that you may also edit this in the GUI using the JobManager module of salome_meca.

Dear all,

I'm trying to add a remote server in Salome-meca, in order to select it for launching computation in AsterStudy.

Following this post, I used "Resource Catalog" panel in jobManager to add a server with the "Edit/Add a resource" popup. As we installed SalomeMeca also on the remote server, I set Applipath to $PATH_INSTALL/Salome_Meca/2019.0.3-1/appli_V2019.0.3_universal.

The new server is indeed available in the roll list of "Run servers" in Run parameters of AsterStudy but a popup indicates "No available versions found on .." and prevents to select it.

This operation also wrote a CatalogResource.xml file in SalomeMeca directory with an item corresponding to the server. I tried to rewrite this file to add the moduleName lines of the first message of this post but the server is no more recognized in the interface.

Is there any documentation somewhere on how to write this CatalogResource.xml file or add information in jobManager or elsewhere in order to make the link with the aster version installed on the remote server ? Do I need for instance to declare something in the "Component List" of the "Edit/Add a resource" popup ?

Regards

Did yo manage to solve your issue? I'm having the same issue

What does your CatalogResources.xml file look like? If you don't have any specifically setting location of this file it should be located in $KERNEL_ROOT_DIR/share/salome/resources/kernel.

I had same issue before and I finally managed to make it work. Based on my experience,

(1) I had to set up a password-less ssh connection

(2) I had to declare the remote server in local /etc/hosts file

(3) set up the appliPath of the resource correctly. That should be the directory which the salome launch executable is in. In my case it is something like $HOME/salome_meca/appli_V****

Good luck.

Hai all,

How to change the "localhost" in asterstudy version 9.7

The server resources are defined in the Job manager module of Salome Meca (blue globe icon). There is a simple GUI to define servers other than localhost ...
