Our /work file system has had an error which renders the file system unusable for the time being.
/home is still working.

We are working to fix this, but there is no timeline for a fix


We apologize for the inconvenience.

Digital Lab Seminar will be held at room 265 Sentral bygg 1 on 6th of November 2019

Idun is currently undergoing maintenance and moving of he entire cluster. The cluster will be unavailable until Wednesday oct. 16 at aprox 15:00

Betzy is the name


https://www.sigma2.no/content/b1-becomes-betzy

The new supercomputer to run heavy duty workloads have benn named "Betzy"

The supercomputer is named after Mary Ann Elizabeth (Betzy) Stephansen, the first Norwegian woman with a Ph.D in mathematics. Read the interesting story of Betzy at NMBUs webpages (in Norwegian).


Introduction to parallel programming

Courses lectured over several afternoons will give an introduction to parallel programming.

All courses are free of charge.

All lectures are held in English.

All courses are held twice every year (February and September).


Registration: Send an e-mail to: adm@hpc.ntnu.no

(Please add your NTNU User Name in the Registration Email)  


Topics covered:

  • A walk through of cluster architectures. Amdahl's vs Gustafsons law. Simple MPI-calls, programs with MPI-collective
  • OpenMP Programming for CPU and GPU, and hybrid programming (MPI/OpenMP). (OpenMP for GPU is only in September)
  • MPI: Programming examples and Algorithms  .
  • (Only in February) Parallel Matlab programming and distributed Matlab using MPI.
  • Introduction to Jupyter Notebooks is a tutorial showing the basic use of Python in a Jupyter Notebook

Install a Matlab Client on your laptop. See http://www.ntnu.no/adm/it/orakel and Programvaredistribusjon

The MPI course consists of two parts: an introduction to MPI and a second part that covers a lot of the examples from the IBM's Redbook "Practical MPI programming", Practical MPI Programming - IBM Redbook

Remember to bring your own laptop.

(For Window users: Please install a ssh client, like X-Win32 (which you find in software.ntnu.no), or PuTTY with an X-server on your computer e.g. Xming 

Date and place. 

Date:  August 29,  September 3. to 12. - 2019

Location: Bygg-teknisk, L10 , Gløshaugen NTNU - Trondheim, Norway .

Problem with Idun

We are working solving this

The system will be down until further notice.

NTNU IT inviterer 28 februar til et historisk tilbakeblikk gjennom tungregnehistorien sett fra Trondheim.

Vi tar for oss de viktigste superdatamaskinene som har vært del av tungregnemiljøet ved NTNU, med spennende og informative innlegg fra de som var tett på maskinene, enten som brukere, driftere eller kunder.

I tillegg til å dekke historien fra 1986 (Cray X-MP) til 2018 (SGI ICE X) tar vi oss også tid til å se på historien før 1986 og vil også se litt på veien videre for HPC ved NTNU og nasjonalt.

Tid er 10:00-16:00 på onsdag 28 februar 2018. Sted er auditorium A3 i Rustbygget/Handelshøyskolen (ELG-A3), ved Hesthagen ved Gløshaugen, se kart i Mazemap: http://bit.ly/2sIJc8n

Det blir servert enkel lunsj.

Arrangementet er gratis.

Reserver plassen din hos Hoopla; det kan bli lenge til neste gang!

Introduction to parallel programming

A new version of the Boost library, http://www.boost.org is released. Now available on vilje as a module.

Maintenance work on Vilje has now been completed and the queuing system is available for jobs.
Due to a database crash, all queued or hold jobs have been lost. We
apologize for this.

Due to system upgrades being installed, Vilje will be unavailable every day from 8:00 to 15:00 from November 21 - 25, both days included. It is possible to run short jobs from 15:00, but these must be finished by 8:00 next day.

Edit: Unfortunately we did not mange to get the new software system finished, so we are now booting the old software "image" and will continue tomorrow. Vilje should be up and running soon.

/work is back

We now believe that the problem with /work has been found and solved. /work is therefore now available again. We apologize for the inconvenience.

We are currently experiencing problems with /work and we don't know when the problems will be solved.

 

Edit: Today Thursday morning the problem have still not been resolved and the vendor is working on resolving it.
