Disk Space and Data Storage
/home/dyb (home)
- Group Quota: 750 GB
- User Quota: 1 GB space
- Home directory for individual files, code development, and
small-scale, individual data analysis.
/dyb/dybdata1
- Group Quota: 400 GB space
/dyb/dybdata2
- Group Quota: 400 GB space
/dyb/dybd01, /dyb/dybd02,.../dyb/dybd05
- Each has 2 TB space, totally 10 TB.
Computing resources for job submission
- There are 15 computing nodes for Daya Bay Experiment: dyb001-dyb015, totally 30 due CPUs (Intel(R) Xeon(TM) CPU 3.00 GHz).
- Create a job script file to run G4dyb, which should be a shell executable. Here is an example JobCommandFile.
- To run N jobs in parallel, you will need to create and submit N such command files, which then contain calls to N mac files. I highly suggest you to do the following:
- create a work directory, e.g. $HOME/work/dyb
- Under your work directory, create directories macros/, commands/, and logs/.
- Put the macro that you would like to run under your work directory. If your ROOT files are bulky, please consider using /dyb/dybd01, /dyb/dybd02, ... /dyb/dybd05 (use "/files/output" command in the macro). Here is an ExampleMacro.
- Modify this PerlScript for your own needs, and put it also under your work directory.
