Linux Cluster Mechthild
Mechthild is a heterogeneous cluster with four different kinds of compute nodes.
|Standard Node||BigMem Node||GPU Node Type 1||GPU Node Type 2|
|CPU:||2x Intel Xeon Skylake Silver 4110||2x Intel Xeon Skylake Silver 4110||2x Intel Xeon Skylake Silver 4110||2x Intel Xeon Skylake Gold 6130|
|Cores per CPU:||8||8||8||16|
|Clockrate:||2.1 GHz||2.1 GHz||2.1 GHz||2.1 GHz|
|RAM:||192 GB DDR4 ECC||384 GB DDR4 ECC||192 GB DDR4 ECC||192 GB DDR4 ECC|
|Network:||Intel OmniPATH 25 GBits/s|
|Theoretical peak performance per node:||537 GFlop/s||537 GFlop/s||537 GFlop/s||1075 GFlop/s|
|Accelerator:||-||-||1x NVidia Tesla P100||1x NVidia Tesla P100|
|Number of nodes:||112||10||5||5|
|Linpack peak performance of all nodes:||60 TFlops/s|
Other hardware components are:
- 1 login node using two Intel Xeon Silver 4110
- 1 service node using two Intel Xeon Silver 4110
- 64 TB BeeGFS network storage
- OmniPath network wirth 1:2 blocking
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
- 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.
The total investment for the system was about 900 000€. The larger part of 750 000€ was funded by the Max Planck society, the remainder was taken from the individual department budgets.
In order to use Mechthild researchers have to sign a separate policy. More details can be found in the internal wiki of our institute.
