Linux Cluster Mechthild
The Linux-Cluster Mechthild is the central computational resource at the MPI Magdeburg. Researchers of all groups can use it for simulations, large and especially distributed computations. The CSC group uses Mechthild especially for the development of scientific software and for computations related to our further research activities. The system is the successor of the old Linux Cluster otto.
Hardware
Mechthild is a heterogeneous cluster with four different kinds of compute nodes.

|---|---|---|---|---|---|
| CPU: | 2x Intel Xeon Silver 4110 | 2x Intel Xeon Gold 6130 | 2x AMD Epyc 7452 | 2x Intel Xeon Platinium 8562Y+ | 2x Intel Xeon Skylake Silver 4210R |
| Cores per CPU: | 8 | 16 | 32 | 32 | 10 |
| Clockrate: | 2.1 GHz | 2.1 GHz | 2.35 GHz | 2.8 GHz | 2.40 GHz |
| RAM: | 192 GB DDR4 ECC/384 GB DDR4 ECC | 192 GB DDR4 ECC | 512 GB DDR4 ECC | 1536/512 GB DDR5 ECC | 768 GB DDR4 ECC |
| Network: | Intel OmniPATH 25 GBits/s | ||||
| Accelerator: | - | 2x NVidia Tesla P100 | 4x / 2x Nvidia Tesla A100 | 4x / 2x Nvidia Tesla H100 | - |
| Harddisk: | - | - | - | 8/1 TB NVMe SSD | 2 TB NVMe SSD |
| Number of nodes: | 46/10 | 5 | 1/4 | 2/10 | 4 |
Other hardware components are:
- 1 login node using two INTEL(R) XEON(R) GOLD 6526Y
- 1 service node using two INTEL(R) XEON(R) GOLD 6526Y
- 128 TB BeeGFS network storage
- OmniPath network
Software
The users of Mechthild have various software packages for mathematical and software-engineering purposes installed. Some highlights are:
- GNU Compiler Collection
- Intel C/C++/Fortran Compiler
- MATLAB®
- Gromacs
- SLURM
- several mathematical libraries (BLAS, Lapack, Deal.II, Fenics)
The installed software is configured and selected using the Modules-system. This gives an easy means to setup a designated working environment, or switch, e.g., to a different compiler suite. Additional software is installed upon request to optimally fulfill the needs of all researchers.
Users
In order to use Mechthild researchers have to sign a separate policy. More details can be found in the internal wiki of our institute.
