FAQ
From NETier2
- How can I get help if I have a problem?
The best place to go for ATLAS help is the CERN hypernews or BNL hypernews. For local issues, contact youssef@bu.edu or brunejo@bu.edu or shank@bu.edu. For sysadmin issues, help@atlas.bu.edu. Please keep in mind that we are a tiny outfit compared to a Tier 1 and we can't do much in the way of software support.
- What machine should I log onto?
atlas-login.bu.edu (we've disabled logins to atlas.bu.edu - this is our overloaded gatekeeper).
- How do I copy files from Castor?
- How do I copy files faster, using FDT?
see our FDT wiki page
- How can I change my default shell to zsh?
Put exec /bin/zsh at the end of your .login file in your home directory.
- What worker nodes are available?
atlas-a01.bu.edu,...atlas-a14.bu.edu,...,atlas-h01.bu.edu,...,atlas-h14.bu.edu.
- kinit is not working to CERN. What should I do?
Try /usr/kerberos/bin/kinit -4 yourname@cern.ch (thanks to Rob Harrington).
- How should I submit a batch job?
qsub -q analysis yourscript.sh. Use qstat to see how it's doing. There is a default maximum of 30 simultaneous running jobs per person. Contact S.Y. if you need to increase this.
- Can I run interactively?
Feel free to run interactively on atlas-login (a.k.a. egg.bu.edu). This is a fast 16 core machine with 64G of memory, 10Gbps internet access and fast access to the GPFS storage.
- What disk space can I use?
/data4s/bu and /data5s/bu (5 Terabytes each). Each node also has a /scratch area which you should also feel free to use.
