SciDB (http://www.scidb.org/) is a parallel database system we are evaluating as part of the Parallel Database Testbed project.

AQL% select * from list('arrays');
Please refer to the SciDB User Manual for usage of SciDB (Attached).
There is Global HOME/SCRATCH on the SciDB nodes. However the Global PROJECT is mounted. You can load data directly from your project directory. Fo temporary storage space, you can create a subdirectory in /global/project/projectdirs/paralleldb/users.
You can transfer your data from global file systems using rsync.
Sharing the System With Other Users
SciDB currently doesn't provide user level access control, this means you can accidentally delete other user's data.
Naming Your Arrays
To distinguish different users, please name your array with your user name as a prefix. For example, if your NIM username is testuser, and the desired array name is myarray, please name your array "testuser_myarray"
This is a testbed system, please backup your data and queries.
