HTCondor jobs require that the job description files (JDF) obey a certain syntax. Some examples of JDF's can be found here:
An example analysis job file would look like the following:
Printing at the SDCC
Print services at the SDCC is only provided on the main RHIC general interactive system, rcf3.rhic.bnl.gov. This system is a RHIC only system. No printing services are available on other systems at the SDCC.
Listing Available Printers
The command lpstat -t lists all print queues on rcf3.rhic.bnl.gov.
Setting a Default Print Queue
To set your default printer, define the PRINTER environment variable to the print queue of your choice.
Quick Start Changes
What do I need to do to run jobs as before? In general not much, however the following will be helpful:
It is rarely the case that a user submits just one job to the batch queue. Often a user will submit hundreds of jobs using custom scripts and tools to automate the process. HTCondor provides tools to make multiple job submission easier. There are two advantages to using these builtin features: first, job submission will be several times faster; second, HTCondor can provide more robust scheduling if sets of jobs are submitted using these tools.
To demonstrate how to submit multiple jobs using HTCondor we start with a vanilla job description file:
The CERN-VM FIle System service at BNL
The SDCC at BNL serves as a CVMFS Stratum One replica server for WLCG and OSG experiment repositories.
US cloud users should configure their clients to point to the RACF replica as their primary server source in their CVMFS_SERVER_URL value, and include other Stratum One servers in the list as fail-overs:
The RCF runs backups on selected NFS and AFS file systems on a nightly basis. These backups are for site disaster recovery only. Restoration of data is available for approved requests only. If you require a restoration, contact your Experiment Liaison to see if your request satisfies the requirements for a special restoration request.
Note: In general, files are retrievable with 30 days of loss.
Home directories -
Home directories are meant to store small files only. All home directories are restricted by user quotas and the quotas varies as per experiment.
You can use "quota -s" to check your quota.
All home directories have a daily backup and snapshot policy. Backups are kept for 30 days and snapshots for 7 days.
Snapshots can be accessed by navigating to the .snapshots directory.
