The main purpose of the COMCHA network is to boost the collaboration related to modern data reconstruction, low power and sustainable hardware architectures, artificial intelligence and new technologies across several physics groups and experiments, including collider, cosmology, astroparticle, nuclear, medical and applied physics. It will help scientific groups to face the present technological challenges, in particular in the area of object reconstruction, identification and selection, machine learning, heterogeneous platforms and new computing paradigms, such as Big Data. COMCHA also gives the Spanish scientific community the opportunity to optimize the resources and infrastructures present in several nodes of the network. COMCHA promotes the training of young researchers, the outreach and the collaboration between groups across several experiments and among different areas of physics research. It also fosters the technology transfer and the collaboration with the industry.
