Installing_job_control

The NLME Job Control System is officially supported on CentOS8/RHEL8.

For using multicore parallelization locally or for parallel processing on a remote host, the following must be installed:

R 4.0 (or later) can be obtained from http://cran.r-project.org.

Note that it should be the same along the nodes used if GRID is used and for additional nodes, it should be available from the path (should override default R).

To facilitate job submission from Windows to RHEL 8 or Ubuntu 22, NLME in Phoenix (on Windows) contains an SSH library. SSH library needs to be installed on all remote hosts that will be used.

On RHEL 8 or Ubuntu 22, use the following (note that this is executed as a root):

     sudo yum install epel-release
     sudo yum install libssh-devel

If the xml2 package is not already installed on your RHEL 8 or Ubuntu 22 distribution, first execute the following command from the terminal in order to install the additional RHEL 8 or Ubuntu 22 system library libxml2-devel (note that this is executed as a root):

     sudo yum install libxml2-devel

Certara.NLME8 within dependencies should be installed on the submission host (or locally, if local multicore control mode is used).

To install the package, start an R session and insert the following code (Jfrog/CRAN repositories are used):

install.packages ("Certara.NLME8",repos = c("https://certara.jfrog.io/artifactory/certara-cran-phoenix-8-5-release-public/", "https://cloud.r-project.org"), method = "libcurl")

The Certara.NLME8 R package installed using this command has version 2.0.1. It is highly recommended that this version be used with Phoenix remote runs to avoid possible incompatibilities.
