Other Stuff to consider
atlas library
module load ATLAS/3.9.39 --with-blas="-L/sw/ATLAS/3.9.39/lib -lf77blas -latlas" For systems with multiple processors it is possible to use a multi-threaded version of ATLAS, by specifying --with-blas="-L/sw/ATLAS/3.9.39/lib -lptf77blas -lpthread -latlas"
mkl library
module load intel-cmkl-11/11.2.137 module load intel-cc-11/11.1.072 R can be linked to a sequential version of MKL by MKL_LIB_PATH=/sw/sdev/intel/ComposerXE/composerxe-2011.2.137/mkl/lib/intel64/ export LD_LIBRARY_PATH=$MKL_LIB_PATH MKL="-L${MKL_LIB_PATH} -lmkl_gf_lp64 -lmkl_sequential -lmkl_lapack -lmkl_core" ./configure --with-blas="$MKL" --with-lapack Threaded MKL may be used by replacing the line defining the variable MKL with MKL="-L${MKL_LIB_PATH} -lmkl_gf_lp64 -lmkl_gnu_thread \ -lmkl_lapack -lmkl_core -liomp5 -lpthread" The default number of threads will be chosen by the OpenMP* software, but can be controlled by setting OMP_NUM_THREADS or MKL_NUM_THREADS. Static MKL may be used with MKL=" -L${MKL_LIB_PATH} \ -Wl,--start-group \ ${MKL_LIB_PATH}/libmkl_gf_lp64.a \ ${MKL_LIB_PATH}/libmkl_gnu_thread.a \ ${MKL_LIB_PATH}/libmkl_core.a \ -Wl,--end-group \ -lgomp -lpthread" The default linking model, which is also used by version 9 of MKL, can be used by --with-blas="-lmkl -lguide -lpthread" This is multi-threaded, but in version 9 the number of threads defaults to 1. It can be increased by setting OMP_NUM_THREADS. (Thanks to Andy Liaw for the information.)
Configuration options
configure has many options: running ./configure --help ‘--with-x’ use the X Window System [yes] ‘--x-includes=DIR’ X include files are in DIR ‘--x-libraries=DIR’ X library files are in DIR ‘--with-readline’ use readline library (if available) [yes] ‘--enable-R-profiling’ attempt to compile support for Rprof() [yes] ‘--enable-memory-profiling’ attempt to compile support for Rprofmem() and tracemem() [no] ‘--enable-R-shlib’ build R as a shared/dynamic library [no] ‘--enable-BLAS-shlib’ build the BLAS as a shared/dynamic library [yes, except on AIX] You can use ‘--without-foo’ or ‘--disable-foo’ for the negatives. You will want to use ‘--disable-R-profiling’ if you are building a profiled executable of R (e.g. with ‘-pg)’. Flag ‘--enable-R-shlib’ causes the make process to build R as a dynamic (shared) library, typically called ‘libR.so’, and link the main R executable ‘R.bin’ against that library. This can only be done if all the code (including system libraries) can be compiled into a dynamic library, and there may be a performance1 penalty. If you need to re-configure R with different options you may need to run make clean or even make distclean before doing so.
config.site
The default optimization settings chosen for CFLAGS etc are conservative. It is likely that using ‘-mtune’ will result in significant performance improvements on recent CPUs (especially for ‘ix86’): one possibility is to add ‘-mtune=native’ for the best possible performance on the machine on which R is being installed: if the compilation is for a site-wide installation, it may still be desirable to use something like ‘-mtume=core2’. It is also possible to increase the optimization levels to ‘-O3’: however for many versions of the compilers this has caused problems in at least one CRAN package. For platforms with both 64- and 32-bit support, it is likely that LDFLAGS="-L/usr/local/lib64 -L/usr/local/lib" is appropriate since most (but not all) software installs its 64-bit libraries in ‘/usr/local/lib64’. To build a 32-bit version of R on ‘x86_64’ with Fedora 14 we used CC="gcc -m32" CXX="g++ -m32" F77="gfortran -m32" FC=${F77} OBJC=${CC} LDFLAGS="-L/usr/local/lib" LIBnn=lib 64-bit versions of Linux are built with support for files > 2Gb, and 32-bit versions will be if possible unless ‘--disable-largefile’ is specified.

R And cuda:
R gputools is not currently installed as it needs EMI Photonics' CULA libraries.
http://brainarray.mbni.med.umich.edu/Brainarray/rgpgpu/ http://cran.r-project.org/web/packages/gputools/index.html
If the gputools package is installed, it will provide R interfaces to a handful of common statistical algorithms. These algorithms are implemented in parallel using a mixture of Nvidia's CUDA langauge, Nvidia's CUBLAS library, and EMI Photonics' CULA libraries. On a computer equiped with an Nvidia GPU some of these functions may be substantially more efficient than native R routines.

How to run R code in parallel : Parallelisation using dplyr and doParallel
Parallelisation using plyr and doParallel
We have plyr and DoParallel in R/4.0.3
Threads vs. cores
There is often a lot of confusion between CPU threads and cores. A CPU core is the actual computation unit. Threads are a way of multi-tasking, and allow multiple simultaneous tasks to share the same CPU core. Multiple threads do not substitute for multiple cores. Because of this, compute-intensive workloads (like R) are typically only focused on the number of CPU cores available, not threads. (Ref: https://jstaf.github.io/hpc-r/parallel/)
Example: module load R/4.0.3 > library(plyr) > library(doParallel) Loading required package: foreach Loading required package: iterators Loading required package: parallel >cores <- detectCores() >cores [1] 72 > registerDoParallel(cores=12) fake_func <- function(x) { Sys.sleep(0.1) return(x) } library(microbenchmark) microbenchmark( serial = llply(1:24, fake_func), parallel = llply(1:24, fake_func, .parallel = TRUE), times = 1 ) Unit: milliseconds expr min lq mean median uq max neval serial 2424.3580 2424.3580 2424.3580 2424.3580 2424.3580 2424.3580 1 parallel 226.2199 226.2199 226.2199 226.2199 226.2199 226.2199 1 >

Create R conda environment (Recommended way on the new cluster) to run R on the new cluster
Another easy way to install R and R packages is to use conda . Here are the steps
source /usr/local/bin/s3proxy.sh module load anaconda3/2024.06 conda create --name myRenv R=4.3.1 source activate myRenv To install packes like "tidyverse","lubridate","ggplot2", "tmap", "ggmap", "sf", "ggsci", "remotes", "raster", "readxl", "terra" Simply google with the package name and conda as search strings e.g. tidyverse conda You will see instructions to install these packages: conda install r::r-lubridate conda install r::r-tidyverse conda install conda-forge::r-ggplot2 conda install conda-forge::r-tmap conda install conda-forge::r-ggmap conda install conda-forge::r-sf conda install conda-forge::r-ggsci conda install conda-forge::r-remotes conda install conda-forge::r-raster conda install conda-forge::r-readxl conda install conda-forge::r-terra Or simply: conda create --name myRenv r=4.3.1 r-tidyverse r-ggplot2 r-tmap r-ggmap r-sf r-ggsci r-remotes r-raster r-readxl r-terra -c conda-forge Here is a sample pbs script: #!/bin/bash #PBS -m abe #PBS -M XXXX@griffithuni.edu.au #PBS -N MyTest #PBS -q workq #PBS -l select=1:ncpus=1:mem=4gb,walltime=01:00:00 module load anaconda3/2024.06 source activate myRenv module list cd $PBS_O_WORKDIR R '--save' <MAIN_CODEmodel1.R ##sleep 22 echo "Done with job"
