APIs elapsed time comparison
This section reports the comparison of the ASALI APIs in term of computational time. These results are obtained with a AMD Athlon(tm) II P320 Dual-Core Processor with Ubuntu 22.04.3 LTS.
If you download ASALI, you can run the same test on your own computer using the following commands:
cd API/elapsedTimeComparison/
./run.sh -n 2000 -f test.md --compile
Assumptions and operating conditions
The gas mixture operating conditions are reported in the following table:
| Property | Value | Unit dimension |
|---|---|---|
| Temperature | 393.15 | K |
| Pressure | 4 | bar |
| H2 | 0.1 | Molar fraction |
| O2 | 0.1 | Molar fraction |
| C3H8 | 0.1 | Molar fraction |
| C2H6 | 0.1 | Molar fraction |
| CH4 | 0.1 | Molar fraction |
| CO2 | 0.1 | Molar fraction |
| HE | 0.1 | Molar fraction |
| N2 | 0.1 | Molar fraction |
| NH3 | 0.2 | Molar fraction |
The performance comparison has the following assumptions:
- Number of runs: 2000
- Elapsed time to initialize output variables is not considered
Results
The table reports the compatutational time required to estimate all thermodynamic and transport properties and the computational time required to initialize ASALI.
