Cray XMT - Matterhorn
This page describes Matterhorn in the following sections
Short Description of the System
Matterhorn belongs to the next generation Cray XMT supercomputing system: it is a massively multi-threaded platform, with shared memory architecture mainly for large-scale data analysis, data mining, and data structuring.
It features 2 TB of globally shared memory and 64 Cray Threadstorm processors which allow to run 8192 simultaneous hardware threads.
Details on How to Access Matterhorn
Users who wish to have access to Matterhorn need either to submit a Data Analytics Project or to contact Maria Grazia Giuffreda.
Matterhorn is accessible via SSH from the frontend ela.cscs.ch as matt.cscs.ch or matterhorn.cscs.ch.
Programming Environment and Supported Software
The software environment on Matterhorn is controlled using the modules framework which is an easy and flexible way to access all the available compilers, tools, and applications.
The compiler for Matterhorn is provided by Cray.
Interactive Jobs
Matterhorn uses a global memory model. Applications have access to memory on any compute processor on the machine.
Data Storage
/scratch
Matterhorn has a scratch partition (/scratch/matterhorn/user_name). Please be aware that /scratch is not backed up and is cleaned once a week. Do not use /scratch for long-term storage.
/project
Access to the shared storage (/project) is also available through the NFS mount point. However, the request for disk space needs to be done at the time of the proposal submission and needs to be well justified.
