## Systems

Each system is characterized by its CPU type, the operating system type and the
mkin version.

```{r}
cpu_model <- benchmarkme::get_cpu()$model_name
operating_system <- Sys.info()[["sysname"]]
mkin_version <- as.character(packageVersion("mkin"))
system_string <- paste0(operating_system, ", ", cpu_model, ", mkin version ", mkin_version)
load("~/git/mkin/vignettes/web_only/mkin_benchmarks.rda")
mkin_benchmarks[system_string, c("CPU", "OS", "mkin")] <- c(cpu_model, operating_system, mkin_version)

if (mkin_version > "0.9.48.1") {
  mmkin_bench <- function(models, datasets, error_model = "const") mmkin(models, datasets, error_model = error_model, cores = 1, quiet = TRUE)
} else {
  mmkin_bench <- function(models, datasets, error_model = NULL) mmkin(models, datasets, reweight.method = error_model, cores = 1, quiet = TRUE)
}
