Data Challenges
At the SLAC meeting it was agreed to separate "experiment definitions" (bands, resolutions, sensitivity level) from "sky models" (LCDM+dust+sync+). Each of these will be designated by a number. The combination of a given experiment definition XX acting on a given sky model YY will be designated XX.YY.
Experiment models, sky models and the datasets obtained by applying for former to the latter will be stored at NERSC at
/project/projectdirs/cmbs4/{expt_xx, sky_yy, data_xx.yy}

Sim Data Sets
Many of the possible xx.yy combinations have been generated and are available on NERSC.
Most of 02.00 through 02.09 exist - these are the "Science Book config".
Most of 04.00 through 04.06 exist - these are the "CDT report config".
NERSC Info
Shared space is available on NERSC, where everyone is welcome to sign-up for an account under the "Data Analysis for Post-Planck CMB Experiments" allocation (PI Borrill). The files are located in the shared CMB-S4 file space (/project/projectdirs/cmbs4). In order to manage this space, all files stored there should be owned by the cmbs4 project account but accessible to the cmbs4 group. To do this:
- log in to the cmbs4 project account following the instructions [here]
- sync the files to an appropriate subdirectory in the project space
- ensure that the permissions are set appropriately (g+rX,o-rwx)
Remember to include a README and to post the details on this wiki page.
For any NERSC issues, including access to the filegroup and/or project account, please contact Julian Borrill.
