[R-sig-ME] glmmTMB, OpenMP and Ubuntu

[meg@-x m@iii@g oii gmx@@et]

Dear all,



I am currently fitting a complex model with glmmTMB that involves random
effects and covariance structures (spatiotemporal autocorrelation). I would
like to try the experimental parallel optimization feature
<https://cran.r-project.org/web/packages/glmmTMB/vignettes/parallel.html>
to reduce computation time. To do this I've setup a virtual machine running
Ubuntu 20.04 on 16+ cores. However, I found no information in how to setup
OpenMP, R and glmmTMB. Is there a step by step guide that I can follow?



The Vignette states the following:

"If your OS supports OpenMP parallelization and R was installed using
OpenMP, glmmTMB will automatically pick up the OpenMP flags from R's
Makevars and compile the C++ model with OpenMP support."

I was not able to find any information on how to install R using OpenMP.



Best,



Xaver
