Star Cloud Data Service Platform
The Star Cloud Data Service Platform integrates data, computing power, and algorithm tools into a new generation of artificial intelligence research platform by constructing high-quality subject datasets and multidisciplinary knowledge bases. It promotes interdisciplinary collaboration, drives the evolution of data-intensive computing, and aims to empower scientific research with computing capabilities. Through co-construction, sharing, and co-governance, the platform builds community services, provides multimodal data services, and interdisciplinary AI innovation services. The three basic services enable cross-domain full-process scientific research collaboration. The platform first supports major national scientific programs and projects and, in the face of complex scientific problems concerning the common destiny of mankind, develops the Chinese solution and contributes to Chinese wisdom.
Differentiable Cosmological Simulation
We present a new approach of differentiable cosmological simulation using the adjoint method and reverse time integration, and we implement it in a particle-mesh N-body library pmwd (particle-mesh with derivatives).
