Pipeline

Repository that contain End-2-End pipeline to perform QUBIC frequency map-making, power spectrum estimation and cosmological analysis.

Description

First step is compute frequency observations based on 3 way to do it :

• Usual map-making by deconvolving multiple peaks (large memory requirement)
• Fake frequency map-making using PySM python package using instrumental noise description
• Spectrum-based map-making assuming perfect or gaussian foregrounds (idealistic model)

Run

To use the code, you must clone the repository with :

https://github.com/mathias77515/Pipeline

Be careful that every qubicsoft dependencies are correctly installed. The code can be run locally but more efficient in Computing Cluster using SLURM system. To send jobs on computing clusters with SLURM system, use the command :

sbatch main.sh

To modify memory requirements, please modify main.sh file, especially lines :

• #SBATCH --partition=your_partition to run on different sub-systems.
• #SBATCH --nodes=number_of_nodes to split data on different nodes.
• #SBATCH --ntasks-per-node=Number_of_taks to run several MPI tasks.
• #SBATCH --cpus-per-task=number_of_CPU to ask for several CPU for OpenMP system.
• #SBATCH --mem=number_of_Giga to ask for memory (in GB, let the letter G at the end i.e 5G)
• #SBATCH --time=day-hours:minutes:seconds to ask for more execution time.
