It is strongly recommended if using Rucio to use a fresh / clean
shell that is different to the one you are using for Athena etc.
If you do need to set up Rucio in the same session, it should be
set up at the time you call
asetup can be done using:
lsetup 'rucio -w'
To load the environment on lxplus do:
lsetup rucio voms-proxy-init -voms atlas
and enter your grid password to the
voms command, answer yes to
any questions (if the client software requests it).
This will set up a proper Python environment to work with Athena, enable the grid environment, set up the Rucio clients and configure them.
Note that this will always set up the latest Rucio client version.
Don’t forget to create your ATLAS proxy if you didn’t do this in the first step:
voms-proxy-init -voms atlas
First lets ask a few simple questions about Rucio, and what Rucio knows about you.
Use the commands:
rucio ping rucio whoami
The first command will print the version of rucio that you have set up and the second will print the information about the Rucio account you are using.
Note that Rucio accounts can represent users (i.e. you), groups (e.g., Higgs) or activities (e.g., tier0), and your credential (c.f., grid certificate) can map to several of these accounts if required (e.g., for group production roles).
Just like namespaces in C++, Rucio has the concept of a Scope and can help to organise datasets etc. To see that there is already a scope for you, type:
rucio list-scopes | grep $USER
On lxplus, the environmental variable
USERis the same as the nickname associated with the rucio account. On other computers, use the variable
RUCIO_ACCOUNTto achieve the same effect.
To see all available scopes, just use the command
All items known to Rucio, e.g., Files, Datasets, Containers, are
created within a scope with a name (known as a Data Identifier or
DID), which is unique within the scope. Everything can then be
defined with a scope and a name:
<scope>:<name>. This is a new
feature for those familiar with
In the MC generation section, you were introduced to the concept of a
DSID, which is a number that shows up as a subset of the
