Graphics
DIANA makes use of OpenGL for displaying graphical content. Workstation class graphics boards like the NVIDIA RTX professional products are designed for OpenGL applications like DianaIE. Therefore they are highly recommended for visualization at the client side.
Recommended: the graphics card must be compatible with OpenGL 3.2.
Memory
DIANA runs optimal if both executable memory and filos file can be kept in system memory. If you want to run multiple jobs at the same time you need to have system memory available for each job. In case of shortage of memory, it is better to run the jobs one at a time.
Persistent Memory Modules
DIANA does not benefit from using NVDIMM persistent memory modules.
CPU
DIANA makes use of parallel and sequential processing. For improving performance we recommend to choose for (single) core performance instead of multiple cores. For example consider using the 18-core 3.20 GHz Intel® Xeon® W5-2565X instead of the 144-core 2.20 GHz Intel® Xeon® 6 6780E 144‑core.
If you plan to run multiple DIANA jobs simultaneously, we recommend a system with multiple cores and a high core performance. Multiple jobs need additional DIANA licenses.
ACCELERATION BOARDS
DIANA is not utilizing the GPU for calculations.
DISK DRIVES
DIANA calculations create very large files. Filos files (.ff) are used continuously during the whole calculation. SSD’s are highly recommended to improve performance. To run intensive DIANA calculations we advise to select at least one SSD for “Write Intensive” use.
