Run an analysis using CRAB
You can use the xrootd service with
CRAB by applying
this patch. Here are the steps:
- You must set
[CMSSW].global_data_service = 1
in your CRAB config.
- CRAB will perform a check to make sure that the dataset you are trying to run on is at Nebraska, Caltech, or UCSD. It will fail if this is not true.
- If the data is at one of the participating sites, then CRAB will allow you to run jobs at any US T2 site, plus T3_US_Omaha. CRAB still obeys your white/black lists, if you'd like to restrict the possible sites further.
So, once you set the
global_data_service
flag in
CRAB, you can basically continue your "normal workflow" with
CRAB.
