Returns:

A dictionary containing the following information --

casa_dir: Root directory of the monolithic CASA distribution
omp_num_threads: Number of OpenMP threads in the current parallel region
data_path: CASA data paths currently in use
numa_mem: Memory properties from the NUMA software perspective
numa_cpu: CPU properties from the NUMA software perspective

Note: The CPU/memory properties reported here reflect the NUMA software view, which may differ from hardware specifications obtained through standard Python functions (e.g., os.cpu_count()) or pipeline.environment.
