Planning the Paths for Software Porting

Table 1 lists the software installation paths involved in the SGE 8.1.9 porting process and the hosts in the SGE cluster.

**Table 1** Paths for software porting
No.	Software Installation Path	Description	Remarks
1	/path/to/SGE	Directory in which the SGE source code is compiled	The installation paths listed in this table are only examples. Shared paths are recommended. All the paths used in the commands in this document are examples only. Use the actual paths planned during the installation process.
2	/path/to/SGE_ROOT	Installation path of SGE

**Table 2** SGE host description
No.	Host	Description
1	Master host	The master host is central for the overall cluster activities. It runs the sge_qmaster daemon and the sge_schedd daemon. These daemons control grid engine system components, such as queues and jobs. The daemons maintain the tables related to component status, user access permissions, and other tasks. By default, the master host also manages the administration hosts and submission hosts. In this document, the node name of the master host is armnode2.
2	Administration host	The administration host runs any type of management operations in the grid engine system.
3	Submission host	Users can submit and control batch processing jobs on the submission hosts. Specifically, after logging in to a submission host, a user can use the qsub command to submit a job, and use the qstat command to monitor the job status.
4	Execution host	The execution hosts run jobs. Therefore, they host queue instances. The execution hosts run the sge_execd daemon. In this document, the node name of the execution host is armnode4.
