-There should be an //Asterix// shortcut on the left side of your desktop. Double-click on it in order to open a window (e.g. with graohics) environment on one of the asterix servers. Each terminal you will open in this environment will run on the same asterix server.

 ===== Which Linux servers should you use? =====
-There are lots of things you can do directly on your local Win7 or Linux desktop (displaying pdf, images, using a text editor, ...), rather than directly on the servers. Never forget that **your local desktop has access to the remote disks on the Linux servers**.
+==== Working directly on your desktop ====
+Always remember that **your local LSCE desktop can [[#accessing_remote_disks|access remote disks on the LSCE servers]]**.
+There are lots of things you can do directly on your **local** Windows 10 or Linux desktop (displaying pdf, images, using a text editor, ...), rather than on the remote servers. For example, if a script running on the servers generates a pdf file, it is more efficient to open this pdf file using ''Acrobat''/''evince'' on your desktop, than by using ''evince'' on the server.
+==== Available servers ====
-Otherwise, use the appropriate Linux servers. The load balancing system will send you to the server that has currently the smallest load
+  * **The LSCE interactive servers**: ''obelix//NN//''. Use ''ssh obelix'' to access these servers, and the //load balancing// system will send you to the server that has currently the smallest load.\\ Never forget that you are sharing these servers with other users! Do not use too much CPU and/or memory for a long time. Heavy computation should be done on the obelix cluster
+    * <code>$ ssh obelix
+Last login: Mon Jun  3 08:49:53 2019 from somewhere
+# You can use one of the following commands if you want to know on which obelix you are
+$ echo $HOST
+obelix5
+$ hostname
+obelix5</code>
-  * asterixN (''ssh asterix'', or ''ssh asterix.lscelb''): use these servers for the usual day-to-day work (things that use less than 1 Gb, don't use 100% CPU for a long time)
+  * **[[https://intranet.lsce.ipsl.fr/informatique/en/calcul/batch.php|The LSCE cluster]]** (aka the //batch system//). Use this for really heavy duty programs
-  * obelixN (''ssh obelix'', or ''ssh obelix.lscelb''): use these servers for interactive processes that will need //more// ram and/or CPU during a //longer// time
+  * **[[http://mesocentre.ipsl.fr/|The ciclad and climserv servers]]**. In some cases, you may need an account to use the [[http://mesocentre.ipsl.fr/|IPSL/ESPRI clusters]], especially if you need to use data files that are already available/mirrored there (e.g. **''CMIPn'' data**), rather than copying the data to LSCE

 ===== Accessing the LSCE servers from outside the LSCE =====
-The only way to access the LSCE servers from outside LSCE is to connect first to the **idefix1.extra.cea.fr** gateway server. Unless you are on a machine that is outside LSCE, but still on the CEA network (e.g. one of the machines of the CEA computing center)
+The only way to access the LSCE servers from outside LSCE is to connect first to the **ssh1.lsce.ipsl.fr** gateway server.
+==== Interactive access ====
-  - Send a mail to [[help-lsce@lsce.ipsl.fr]], and request an access to the idefix1 server
+  - Send a mail to //help-lsce//, and request an access to the //ssh1// server
-  - Use ssh to connect to idefix1
+  - Use ''ssh'' to **connect** to //ssh1//
-    * From a Linux/mac desktop: ''ssh -A -X your_lsce_login@idefix1.extra.cea.fr''
+    * From a terminal on a Linux/Windows10/Mac computer: ''ssh -A -X your_lsce_login@ssh1.lsce.ipsl.fr''
-    * From a Windows desktop:
+    * From a Windows computer:
-      * Text only: use [[other:win7apps#putty|Putty]]
+      * Text only: use [[other:win10apps#putty_pageant|Putty]]. Putty allows you to open text terminals on remote computers
-      * Text & graphics. This is more complex to set up, and you need to use one of the options below:
+      * Text **and graphics**: you need to [[https://wiki.lsce.ipsl.fr/pmip3/doku.php/other:win10wsl#using_an_x_server|install an X server]] on your computer in order to display the graphics
-        * use [[other:win7apps#putty|Putty]] **and** [[other:win7apps#cygwin-x|cygwin/X]]
+  - You can access all LSCE disks from //ssh1//, but there is only a limited number of programs that you can run, so you have to go from //ssh1// to //obelix// or //irene// with one of the ''ssh'' commands below:
-        * use [[other:index#virtualbox_notes|VirtualBox]]
+    * ''ssh obelix''
-  - There is only a limited number of programs that you can run on idefix1, so you have to go from idefix1 to asterix, obelix or curie with on of the //ssh// commands below:
-    * ''ssh asterix.lscelb''
-    * ''ssh obelix.lscelb''
     * ''ssh your_tgcc_login@curie-ccrt.ccc.cea.fr''

   - You can define an alias in order to connect more easily to the machines:
-    * //tcsh// users: add the following line to your ''~/.cshrc'' configuration file\\ ''alias iasterix 'ssh -A -X your_lsce_login@idefix1.extra.cea.fr -t ssh -A asterix.lscelb'''
