This wiki is the main documentation source for information about the Academic Leiden Interdisciplinary Cluster Environment (ALICE) cluster. ALICE is the research computing facility of the partnership Leiden University and Leiden University Medical Center. It is available to any researcher from both partners. In this wiki, we will introduce the ALICE cluster in detail. We assume you know your way around in a terminal session and that you will responsibly use the cluster and respect the available resources. Remember that a cluster runs many different processes submitted by many different users. If you are not sure what you are doing, ask your administrator before submitting very intensive jobs.

Why ALICE

High-Performance Computing (HPC) previously the domain of theoretical scientists and computer and software developers is becoming ever more important as a research tool in many research areas. An HPC facility, providing serious computational capabilities, combined with easy and flexible local access, is a strong advantage for these research areas. ALICE is the HPC facility that answers those needs for Leiden University (LU) and Leiden University Medical Center (LUMC). It is available to all researchers and students from both LU and LUMC.

The ALICE facility currently implemented is a first phase edition of what will be a larger Hybrid HPC facility for research, exceeding the capabilities of what individual institutes can build and will provide a stepping stone to the larger national facilities. Although the current implementation is located at two data centres (LU and LUMC) it is one.

The facility aims to be an easily accessible, easily usable system with extensive local support at all levels of expertise. Given the expected diverse use, diversity is implemented in all aspects of computing, namely: the number of CPU's, GPU's and the ratio of these two numbers; the size of the core memory to the CPU's; the data storage size and location; and the speed of the network.

ALICE provides not only a sophisticated production machine but is also a tool for educating all aspects of HPC and a learning machine for young researchers to prepare themselves for national and international HPC.

Future plans

ALICE will be expanded over the coming years. Apart from our own expansion plans, we are always open to collaborate with other groups/institutes on expanding and improving ALICE.

The expansion that are currently being discussed include:

  • Expansion of temporary storage (late 2020)
  • Additional login node(s) with GPUs (late 2020)
  • Additional GPU nodes (estimated early 2021)
  • Additional CPU nodes (estimated Q2 2022)

Off to research computing Wonderland

ALICE (Academic Leiden Interdisciplinary Cluster Environment) is the high-performance computing (HPC) facility of the partnership between Leiden University and Leiden University Medical Center (LUMC). It is available to any researcher from both partners. Leiden University and LUMC aim to help deliver cutting edge research using innovative technology within the broad area of data-centric HPC. Both partners are responsible for the hosting, system support, scientific support and service delivery of several large super-computing and research data storage resources for the Leiden research community.

This wiki is the main source of documentation about the ALICE cluster.

Costs overview

Currently, access to the ALICE cluster and related services is provided free of charge to all researchers and students at LU and LUMC.
