Architecture
PLEIADI is a project by USC VIII-Computing of INAF – National Institute for Astrophysics, offering high-performance computing (HPC) and high-throughput computing (HTC) resources.
Individual researchers and teams belonging to research projects, European projects, PRIN, INAF mainstream projects, scientific missions, etc. that require computing can apply requesting the resources.
The Pleiadi infrastructures is distributed on the following sites:
