Dear ASC users, the AURELEO DCGP 2025 Call is open! Austria owns a small share of the LEONARDO DCGP (Data-Centric General-Purpose) partition at the LEONARDO supercomputer operated by CINECA in Bologna. The nodes of this partition are equipped with two Intel Sapphire Rapids CPUs, each with 56 cores, that are known for their extremely high memory bandwidth. In addition, the DCGP partition uses Mellanox HDR 200Gb/s InfiniBand connectivity, with smart in-network computing acceleration engines that enable extremely low latency and high data throughput to provide the highest HPC application performance and scalability. The DCGP is a CPU only partition. Test access to the LEONARDO DCGP partition is possible for active ASC users in non-commercial projects and because of the limited amount of resources it is suited for testing and/or benchmarking only (we can give up to 1 million core hours per project at maximum, but it depends on the number of incoming applications). Such a test access might be especially useful if you have a memory-bandwidth bound application and in general for everyone interested to test the Intel Sapphire Rapids CPUs. If after testing the DCGP partition appears to be useful to you, we can help you to apply for a larger allocation on this partition via a standard EuroHPC Access Call. Active ASC users in non-commercial projects can get test access to the LEONARDO DCGP partition by requesting a test user in the joint "DCGP Austria 2025" project that will run 01.09.2025 - 01.09.2026 at CINECA. In order to apply, send an email to leonardo@vsc.ac.at telling your VSC project and VSC username, when and how long you would like to get access, the amount of core hours you would like to get, and a short description of your project and why you think that your application can benefit from using the LEONARDO DCGP partition (max half a page). We will check if your application is suitable for the LEONARDO DCGP partition as well as eligibility and grant you short-term access on a first-come first-serve basis. For this we will also ask you to register in the CINECA User DB. Please note, that resources on LEONARDO are given on a monthly basis and follow a linearization policy. You should be able to start calculations at the beginning of your requested project start date (preferably on 01.09.2025). After your test access is over, we will ask you to provide a short feedback (max half a page) about your experience with running your application on the LEONARDO DCGP partition. There is no formal deadline, we accept rolling applications until the resources in the joint "DCGP Austria 2025" project are exhausted. The application process is just via email to leonardo@vsc.ac.at as outlined above. If you do have some urgent demand for CPU hours on LEONARDO DCGP you can still request some resources (a few 100 k core hours) in the running "DCGP Austria 2024" project that will expire on 01.10.2025.
