Each system is characterized by the operating system type, the CPU type, the
mkin version, and, as in June 2022 the current R version lead to worse
performance, the R version. A compiler was available, so if no analytical
solution was available, compiled ODE models are used.
Every fit is only performed once, so the accuracy of the benchmarks is limited.
```{r include = FALSE}
cpu_model <- benchmarkme::get_cpu()$model_name
# Abbreviate CPU identifiers
cpu_model <- gsub("AMD ", "", cpu_model)
cpu_model <- gsub("Intel\\(R\\) Core\\(TM\\) ", "", cpu_model)
cpu_model <- gsub(" Eight-Core Processor", "", cpu_model)
cpu_model <- gsub(" CPU @ 2.50GHz", "", cpu_model)
operating_system <- Sys.info()[["sysname"]]
mkin_version <- as.character(packageVersion("mkin"))
R_version <- paste0(R.version$major, ".", R.version$minor)
system_string <- paste0(operating_system, ", ", cpu_model, ", mkin ", mkin_version, ", R ", R_version)
benchmark_path = normalizePath("~/git/mkin/vignettes/web_only/mkin_benchmarks.rda")
load(benchmark_path)
# Used for reformatting the data on 2022-06-30
# mkin_benchmarks[, "R"] <- NA
# mkin_benchmarks <- mkin_benchmarks[c(2, 1, 15, 3, 4:14)]

mkin_benchmarks[system_string, c("CPU", "OS", "mkin", "R")] <-
c(cpu_model, operating_system, mkin_version, R_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)
}
}
```
## Test cases
Parent only:
```{r parent_only, warning = FALSE}
FOCUS_C <- FOCUS_2006_C
FOCUS_D <- subset(FOCUS_2006_D, value != 0)
parent_datasets <- list(FOCUS_C, FOCUS_D)
t1 <- system.time(mmkin_bench(c("SFO", "FOMC", "DFOP", "HS"), parent_datasets))[["elapsed"]]
t2 <- system.time(mmkin_bench(c("SFO", "FOMC", "DFOP", "HS"), parent_datasets,
error_model = "tc"))[["elapsed"]]
```
One metabolite:
```{r one_metabolite, message = FALSE}
SFO_SFO <- mkinmod(
parent = mkinsub("SFO", "m1"),
m1 = mkinsub("SFO"))
FOMC_SFO <- mkinmod(
parent = mkinsub("FOMC", "m1"),
m1 = mkinsub("SFO"))
DFOP_SFO <- mkinmod(
parent = mkinsub("FOMC", "m1"),
m1 = mkinsub("SFO"))
t3 <- system.time(mmkin_bench(list(SFO_SFO, FOMC_SFO, DFOP_SFO), list(FOCUS_D)))[["elapsed"]]
t4 <- system.time(mmkin_bench(list(SFO_SFO, FOMC_SFO, DFOP_SFO), list(FOCUS_D),
error_model = "tc"))[["elapsed"]]
t5 <- system.time(mmkin_bench(list(SFO_SFO, FOMC_SFO, DFOP_SFO), list(FOCUS_D),
error_model = "obs"))[["elapsed"]]
```
Two metabolites, synthetic data:
```{r two_metabolites, message = FALSE}
m_synth_SFO_lin <- mkinmod(parent = mkinsub("SFO", "M1"),
M1 = mkinsub("SFO", "M2"),
M2 = mkinsub("SFO"),
use_of_ff = "max", quiet = TRUE)
m_synth_DFOP_par <- mkinmod(parent = mkinsub("DFOP", c("M1", "M2")),
M1 = mkinsub("SFO"),
M2 = mkinsub("SFO"),
use_of_ff = "max", quiet = TRUE)
SFO_lin_a <- synthetic_data_for_UBA_2014[[1]]$data
DFOP_par_c <- synthetic_data_for_UBA_2014[[12]]$data
t6 <- system.time(mmkin_bench(list(m_synth_SFO_lin), list(SFO_lin_a)))[["elapsed"]]
t7 <- system.time(mmkin_bench(list(m_synth_DFOP_par), list(DFOP_par_c)))[["elapsed"]]
t8 <- system.time(mmkin_bench(list(m_synth_SFO_lin), list(SFO_lin_a),
error_model = "tc"))[["elapsed"]]
t9 <- system.time(mmkin_bench(list(m_synth_DFOP_par), list(DFOP_par_c),
error_model = "tc"))[["elapsed"]]
t10 <- system.time(mmkin_bench(list(m_synth_SFO_lin), list(SFO_lin_a),
error_model = "obs"))[["elapsed"]]
t11 <- system.time(mmkin_bench(list(m_synth_DFOP_par), list(DFOP_par_c),
error_model = "obs"))[["elapsed"]]
```
```{r results}
mkin_benchmarks[system_string, paste0("t", 1:11)] <-
c(t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t11)
save(mkin_benchmarks, file = benchmark_path)
# Hide rownames from kable for results section
rownames(mkin_benchmarks) <- NULL
```
## Results
Benchmarks for all available error models are shown. They are intended for
improving mkin, not for comparing CPUs or operating systems. All trademarks
belong to their respective owners.
### Parent only
Constant variance (t1) and two-component error model (t2) for four models
fitted to two datasets, i.e. eight fits for each test.
```{r, echo = FALSE}
kable(mkin_benchmarks[, c(1:4, 5:6)])
```
### One metabolite
Constant variance (t3), two-component error model (t4), and variance by variable (t5)
for three models fitted to one dataset, i.e. three fits for each test.
```{r, echo = FALSE}
kable(mkin_benchmarks[, c(1:4, 7:9)])
```
### Two metabolites
Constant variance (t6 and t7), two-component error model (t8 and t9), and
variance by variable (t10 and t11) for one model fitted to one dataset, i.e.
one fit for each test.
```{r, echo = FALSE}
kable(mkin_benchmarks[, c(1:4, 10:15)])
```
