Intranet of the Institute of Material Simulation
Courses Material
This is the workbench of the Institute for Material Simulation. It is intended to be a common source of information for the members of the Institute, Scientists, students and others.
This is a working site and will change and grow.

| sim08 | special | 8 cores, \~16 GB RAM | \~ | \~ | limited |
historic machines
For running old simulations we keep some old systems. They can be activated instead of the current simulation nodes.
| sim32 | cl1 | \~8 cores, \~4 GB RAM | Fedora 32 (2021) | \~ | maintenance |
|---|---|---|---|---|---|
| sim30 | cl1 | \~8 cores, \~4 GB RAM | Fedora 30 (2020) | \~ | on demand |
| sim29 | cl1 | \~6 cores, \~4 GB RAM | Fedora 29 (2019) | \~ | on demand |
| sim27 | cl1 | \~6 cores, \~4 GB RAM | Fedora 27 (2018) | \~ | on demand |
| sim25 | cl1 | \~6 cores, \~4 GB RAM | Fedora 25 (2017, lammps with atomistica) | \~ | on demand |
| sim23 | cl1 | \~4 cores, \~4 GB RAM | Fedora 23 (2016) | \~ | on demand |
| sim1204 | cl1 | \~4 cores, \~4 GB RAM | Ubuntu 12.04 (2014) | \~ | on demand |
If you have demand for some special configurations, more cores more memory on one of the simulation nodes, or you want to try some historic machines just ask the IT to reconfigure the systems
Intel ME Security Vulnerability (INTEL-SA-00086)
12.05.2017 - 16:00
The security vulnerability public since 1. Mai 2017 (INTEL-SA-00075, INTEL-SA-00086) has now been categories by Intel as severe.
Most PCs, Laptops and Servers based on Intel CPUs can be captured, crashed or damaged, remote or with an USB-stick, powered up or not.
Intel published a detection tool for testing the own system:
Downtime of HPC clusters LiMa, TinyFAT & parts of Woody on Mon, May 15.
12.05.2017 - 16:00
Do to urgent work on the power grid, the HPC clusters LiMa, TinyFAT & parts of Woody (w10xx = :sb) have to shut down on Monday, May 15th starting at 7 o'clock in the morning. As usual, jobs that would collide with the downtime will be postponed.
Check the MOTD when logging into the clusters for updates.
New Repositories: SVN ⟶ GIT
28.04.2017 - 14:00
Starting from today our old subversion repositories on ww8depot.ww.uni-erlangen.de/svn/ will be moved to our new
SimLab(git) repository management system, which is based on GIT.
In this process the repositories will be converted to GIT.
To access the repositories on SimLab you have to log in there once and ask an administrator (me) to give you rights for the repository. This has only to be done for the first repository, all other access rights will be added automatically by the system (hopefully).
If you can not access your repositories any more or have questions about the usage of GIT.
If the demand for counselling is big enough and questions arise about how to plan and handle a project with the new GIT-workflow we should hold a panel and discuss best practices.
