GitLab upgrade completed. Current version is 17.10.3. We now benefit from the enhancements of 17.9 and 17.10 releases. Among other improvements, it is now possible to set the automatic deletion of continuous integration pipelines. You can help us reduce storage usage by setting an expiry date for your pipelines.

After several discussions inside the PS team, we have fixed some attributes but some still require a decision (those with a leading *). We cannot change the names of the fixed attributes for backward compatibility reasons, only their role if necessary. <u>'''Underlined attributes'''</u> would always have to be defined.
* <u>'''interface'''</u>: the type of network interface, ∈ {"Ethernet", "Myrinet", "InfiniBand"}
After several discussions inside the PS team, we have fixed some attributes. All of them are mandatory, but the ones between square brackets are only <font color="#FF0000">mandatory under conditions</font>. Those conditions follow the field name, in <font color="#FF0000">red</font>.
* '''interface''': the type of network interface, ∈ {"Ethernet", "Myrinet", "InfiniBand"}
:: NB: It is useless to define "Myrinet 10G" or "Myri-2000" values, because the '''rate''' will differentiate them.
* <u>'''rate'''</u>: speed of the interface in b/s
* * <u>'''mac'''</u>: the MAC address of this interface
:: Alternate propositions: '''mac_address'''
* '''rate''': speed of the interface in b/s
* '''mac''':
:if '''interface''' ∈ {"Ethernet", "Myrinet"}, the MAC address of this interface,
:if '''interface'''=="InfiniBand", its GUID.
* '''vendor''': the company which made the device
* '''version''': its version according to the company nomenclatura
* '''driver''': name of the driver for the device in the linux kernel
* <u>'''enabled'''</u>: <code>true</code> if there is any cable connected to this interface
* * <u>'''management'''</u>: <code>true</code> if this interface is on the administration network (IPMI,...)
* * <u>'''mountable'''</u>: <code>true</code> if it is usable by any user (even if it possibly requires a customized environment)
* * <u>'''device'''</u>: name of this interface in the production environment (would be <u>'''mandatory'''</u> if '''mounted'''==true)
* '''network_address''': the DNS entry of the machine by this interface (<u>'''mandatory'''</u> if '''mounted'''==true)
* '''ip''': the IP of this interface (<u>'''mandatory'''</u> if '''enabled'''==true)
* * '''ip6''': the IPv6 of this interface, for future use...
:: Alternate propositions: '''ipv6_address'''
There is also a proposition where '''mounted''' is renamed as '''enabled''', which preserves the backward compatibility on the attribute name, but the role of '''enabled''' would be given to an attribute '''connected''', or '''wired'''.
* '''enabled''': <code>true</code> if there is any cable connected to this interface
:* ['''management''']''<font color="#FF0000">(if '''enabled'''==true)</font>'': <code>true</code> if this interface is on the administration network (IPMI,...)
::* ['''network_address''']''<font color="#FF0000">(if '''mounted'''==true or '''management'''==true)</font>'': the DNS entry of the machine by this interface
:* ['''mountable''']''<font color="#FF0000">(if '''enabled'''==true)</font>'': <code>true</code> if it is usable by any user (even if it possibly requires a customized environment)
::* ['''driver''']''<font color="#FF0000">(if '''mountable'''==true)</font>'': name of the driver for the device in the linux kernel
::* ['''mounted''']''<font color="#FF0000">(if '''mountable'''==true)</font>'': <code>true</code> if the production environment mounts, configures this interface

:* ['''ip6''']: the IPv6 of this interface, for future use...
[ EDIT - 2010-09-13 ] No contestation, no more votes for the alternate propositions and no other entry proposed => the base version is validated.
