Table 2
Average execution time per call for the JFNK and the RH92 solvers.
| Setup | JFNK (ms/call) | JFNK (with preconditioner) (ms/call) | RH92 (ms/call) |
|---|---|---|---|
| Ca II (2 levels + continuum) | 55 | 121 | 65 |
| Ca II (5 levels + continuum) | 254 | 672 | 310 |
| H I (5 levels + continuum) | 510 | 1160 | 631 |
Notes. Each call consists of the operations required to update the population densities once (and optionally, of the preconditioner for the JFNK solvers). None of the codes was designed to be optimal. The JFNK solvers are slightly more efficient than the RH92 solver (without the preconditioner update). Runs were executed on a MacBook Pro provided with an Apple M1 Pro chip.
