# ELPA Library
|
|
|
|
For static calculations, it is recommended to use [ELPA](https://elpa.mpcdf.mpg.de/) Library, which has better performance than ScaLapack. In particular, ELPA allows for the utilization of GPUs which provide a significant boost for calculations. In order to activate ELPA lib in [predefines.h](https://gitlab.fizyka.pw.edu.pl/gabrielw/wslda/-/tree/public/st-myproject-template/predefines.h) set:

## Plots

|
|
These scalings are derived empirically: points correspond to **real** measurement on target system, while line shows a fit of ideal scaling for level-3 rutines ($`\sim N^3`$)

The scaling was derived within ALCC grant [Quantum Turbulence in Fermi Superfluids](https://www.olcf.ornl.gov/web-project/quantum-turbulence-in-fermi-superfluids/).
