1.0 Introduction

IT for Science group provides resources and consulting services for the research community. This document provides an compendium of the free resources available for the research community. In short, we provide following services: 

  • Cubbli Linux distribution
  • GPU capacity, up to 20 GPU's available for interactive and batch use.
  • High Performance Computational capacity in three facilities for interactive and batch use.
  • Fast I/O
  • Consulting services and best practices.

1.1 Can I buy my own servers?

You may be considering procuring computational resources, wether they are GPU machines for Deep Learning, regular servers for computing, servers for heavy duty database use, or storage capacity and have checked that your requirement is something we do not yet offer. We have a good news. We can house servers that are used for computational tasks and incorporate them gladly to the existing pool of resources. These can be for example: 

    • Dedicated to you alone, or...
    • Your research group could ask for pre-emption capability, or...
    • A standard addition to common pool without special privileges besides of becoming an Investor User.

You can always opt to increase the common pool of resources at any time. Even ones that have been dedicated before.

1.1.1 We offer benefits

    • Standard, centrally managed Centos7 Linux environment.
    • All the software modules listed later in this document.
    •  Very high throughput/low latency I/O ($WRKDIR).
    • Automated data migration from $WRKDIR to CEPH data lake - Planned 2019Q2.
    • Other resources in a same high-bandwidth interconnect fabric.
    • Resource Usage statistics.
    • You can utilize our procurement process and therefore get better deals.

1.2 If you still think you must choose yourself, we have something to say...

In exchange for above benefits, we have a few requirements for servers that are not bought by us:

    • Rack mountable server, or chassis solution
    • Infiniband nic (depending on the bandwidth requirement, this can be FDR (56Gb/s) and EDR (100Gb/s))
    • Associated IB cable

1.3 Because

1.3.1 Why should I become Investor User?

    • You will be granted higher percentage of the shares of the computational resources.
    • Being investor user is especially beneficial when your jobs are resource intensive.
    • Having more shares means that job priorities decay slower.

1.3.2 Why not to use dedicated servers?

    • A history has shown that dedicated resources are often ill utilized. Utilization of less than 20% is very common.
    • Larger pool of common resources enables greater availability for everyone.
    • When resources are not dedicated, you can scale immediately upwards whenever you have temporary need.
    • Pooled resources are immediately available for use.
    • We are flexible, and if you know in advance, we can create resource reservations in advance.

If you would need to have dedicated pool of $WRKDIR I/O resources which is only accessible by named research group, we can do this as well. In this case you should contact us and we will discuss the details.

You can find additional details about access, restrictions etc and other topics in the User Guides. 

1.4 Other topics

A brief information about general University wide terms and conditions can be found through the links listed below.

For any concerns, questions or comments you can reach us in person at Kumpula campus, or through the university helpdesk at  helpdesk (at) helsinki (dot) fi . Resource requests, and bug reports should be addressed through  helpdesk (at) helsinki (dot) fi .

2.0 Cubbli Linux

Cubbli Linux distribution is fully supported by IT4SciFi. Please see the Cubbli Linux  for additional information about availability and release notes. Cubbli Linux is available for servers, workstations and laptops.

Cubbli documentation also here (in Finnish).

3.0 HPC Environment

If, and when the demand of computational resources exceed the capabilities of ordinary workstation, we invite you to utilize our HPC resources. We offer significant GPU, CPU and I/O resources, and fairly comprehensive - and constantly updated library of scientific software, compilers and programming environments. Should you have specific resource need  not listed here, you can contact us through helpdesk (at) helsinki (dot) fi. If you know that your workload scales beyond our resources, you can take a look at the national supercomputing resources available at CSC.

Below you can find a list of hardware resources available on the high performance computing platform. 'How to access example' refers to the use of batch scheduler flags. Notes include special details of the components included. 'HT' indicates that CPU Hyperthreading is used on the nodes to increase the core count. 

Note that sometimes Vendors have grants for certain resources as indicated on the list. Do check if you are eligible.

4.0 Storage and I/O

List of available I/O resources for the users. If a I/O resource is missing from the list, or there are bugs/problems or other concerns, please do contact us through university helpdesk at helpdesk (at) helsinki (dot) fi.  We are investing on high performance I/O, and additional computational resources at the moment, and expect a fresh capability to be in production 1Q2019.

6.0 Open Source Software & Libraries

This list includes most of the special scientific software packages, tools and specialized libraries made available by IT4SciFi. Items on this list have multiple versions available on the clusters and different versions cam be managed with Modules. If the utility, tool, library or program, or specific version is not present and you would like it to be included, please do not hesitate to contact us through university helpdesk at helpdesk (at) helsinki (dot) fi

You can also create modules for of your own software and then share it conveniently within the research group if you like. We have brief instructions here.

All system and development libraries are present on the computational environment by default, and therefore not included in the list - except where tools are installed as modules in the HPC environment. 

Aalto software modules

You are also eligible to use software module from Aalto univerisity. However these are not defaulted because the module list would be very long. To have Aalto modules included, please add modules:

module use /cvmfs/
module use /cvmfs/
