Identifying
all the machines in the environment is critical to ensuring that the SAS High-Performance Computing Management Console
can perform operations in parallel or serially on the machines in
the cluster. The
/etc/gridhosts file
is used to identify the machines. It is a list of the machines, with
one host name on each line. The
/etc/gridhosts file
is not the same as the
/etc/hosts file.
The
/etc/gridhosts
file is created immediately after installing SAS High-Performance Computing Management Console.
If the /etc/gridhosts file
has not been created already, then follow the steps described in Creating the File. The console is also used to manage the host names that
are listed in the file. The following sections provide more detail.
