Often users want to submit a large amount of jobs all at once with each using different parameters for each job. These parameters could be anything including the path of a data file to different input values for a program. This how-to will show you how you can do this using a simple python script, a CSV file, and a template script. You will need to adapt this advice for your own situation.
PnetCDF is a library providing high-performance parallel I/O while still maintaining file-format compatibility with Unidata's NetCDF, specifically the formats of CDF-1 and CDF-2. Although NetCDF supports parallel I/O starting from version 4, the files must be in HDF5 format. PnetCDF is currently the only choice for carrying out parallel I/O on files that are in classic formats (CDF-1 and 2). In addition, PnetCDF supports the CDF-5 file format, an extension of CDF-2, that supports more data types and allows users to define large dimensions, attributes, and variables (>2B elements).
OSC has operated a number of supercomputer systems over the years. Here is a list of previous machines and their specifications.

Batch requests are handled by the TORQUE resource manager and Moab Scheduler as on the Oakley and Glenn systems. Use the
qsub command to submit a batch request,
qstat to view the status of your requests, and
qdel to delete unwanted requests. For more information, see the manual pages for each command.
There are some changes for Ruby, they are listed here:
C, C++ and Fortran are supported on the Ruby cluster. Intel, PGI and GNU compiler suites are available. The Intel development tool chain is loaded by default. Compiler commands and recommended options for serial programs are listed in the table below. See also our compilation guide.
The following are technical specifications for Ruby. We hope these may be of use to the advanced user.
