load_parameters - Grid Engine default load parameters

The load parameters reported by the execution daemon sge_execd(8) by default currently are:

An architecture string compiled into the sge_execd describing the operating system architecture for which the execd is targeted. Possible values include:
	aix51		for IBM AIX 5.1, 5.3
	darwin-x86	for Apple Mac OS/X x86
	darwin-ppc	for Apple Mac OS/X PowerPC
	hp11		for HP HP-UX 11.x 32-bit
	hp11-64		for HP HP-UX 11.x 64-bit
	lx-amd64	for GNU/Linux x86_64
	lx-x86		for GNU/Linux x86
	sol-sparc64	for Sun Solaris Sparc64
	sol-x86		for Sun Solaris x86
	sol-amd64	for Sun Solaris x86_64
	win32-x86	for Windows x86
Note that an sge_execd for a particular architecture may run on multiple OS versions. In this case, the architecture string delivered by the execution daemon may be misleading.
The number of processors provided by the execution host. The host is defined by a single Internet address, i.e. rack mounted multi host systems are counted as a cluster rather than a single multi headed machine. In the case of "hardware threads" ("CMT" or "SMT"), normally num_proc is the number of such threads which are activated.

The following load information is only available under IBM AIX if Grid Engine is built with the perfstat library (which is now the default):

The short time average OS run queue length. It is the first of the value triple reported by uptime(1). Many implementations provide a 1 minute average with this value.
The medium time average OS run queue length. It is the second of the value triple reported by uptime(1). Many implementations provide a 5 minute average with this value.
The long time average OS run queue length. It is the third of the value triple reported by uptime(1). Many implementations provide a 10 or 15 minute average with this value.
The same as load_medium.
The same as load_short but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.
The same as load_medium but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.
The same as load_long but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.
The same as load_avg but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.
The percentage of CPU time not in idle state.

The following load information is only available under IBM AIX if Grid Engine is built with the perfstat library (which is now the default):

The amount of free real memory.
The amount of free swap memory.
The sum of mem_free and swap_free.
The amount of memory used.
The amount of swap space used.
The sum of mem_used and swap_used.
The total amount of memory (free+used).
The total amount of swap space (free+used).
The sum of mem_total and swap_total.

The following load information is ONLY available under Windows:

The host is capable of displaying the GUI of a Windows job.

The following load information is only available if Grid Engine was built with the hwloc library (the default) and if hwloc supports the system.

The host cpu topology string reported by an execution host. This might be "NONE" if the topology cannot be determined; otherwise it is a string consisting of the upper and lowercase letters "S", "C", "T", "c", and "t". The sequence of letters within that string represents the hardware topology where "S" represents a socket, "C" or "c" a core, and "T" or "t" a hardware thread.

The string "SCCSCCSCCSCC" will returned by a host that has 4 sockets where each of those sockets has two cores. All cores are available because all "C"s appear in capital letters.

If lowercase letters are used then this means that the corresponding core or thread is already in use because there is at least one running Grid Engine job bound to it.

"SCCSCcSCCscc" means that core 2 on socket 2 and also core 1 and core 2 on socket 4 are in use.

Like m_topology_inuse, except that it represents the architecture, not the use of it, i.e. it doesn't contain lower case letters.
Number of sockets available on the reporting host (e.g. "SCCSCCSCCSCC" => m_socket=4)
Number of cores reported for all sockets on a host (e.g. "SCCSCCSCCSCC" => m_core=2)
Number of hardware threads reported for all cores on a host, which should be equal to num_proc (e.g. "SCTTCTTCTTCTT" => m_thread=8)

The "static" load values (which may be selected with qhost -l or qselect -l) are: arch, num_proc, mem_total, swap_total, virtual_total, m_topology, m_socket, m_core, m_thread.
