LOAD_PARAMETERS(5)

NAME
load_parameters - xxQS_NAMExx default load parameters

DESCRIPTION
The load parameters reported by the execution daemon by default currently are:

arch
    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.

num_proc
    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 xxQS_NAMExx is built with the perfstat library (which is now the default):

load_short
    The short time average OS run queue length. It is the first of the value triple reported by Many implementations provide a 1 minute average with this value.

load_medium
    The medium time average OS run queue length. It is the second of the value triple reported by Many implementations provide a 5 minute average with this value.

load_long
    The long time average OS run queue length. It is the third of the value triple reported by Many implementations provide a 10 or 15 minute average with this value.

load_avg
    The same as load_medium.

np_load_short
    The same as load_short but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.

np_load_medium
    The same as load_medium but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.

np_load_long
    The same as load_long but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.

np_load_avg
    The same as load_avg but divided by the number of processors. This value allows comparing the load of single and multi-headed hosts.

cpu The percentage of CPU time not in idle state.

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

mem_free
    The amount of free real memory.

swap_free
    The amount of free swap memory.

virtual_free
    The sum of mem_free and swap_free.

mem_used
    The amount of memory used.

swap_used
    The amount of swap space used.

virtual_used
    The sum of mem_used and swap_used.

mem_total
    The total amount of memory (free+used).

swap_total
    The total amount of swap space (free+used).

virtual_total
    The sum of mem_total and swap_total.

The following load information is ONLY available under Windows:

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

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

m_topology_inuse
    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 xxQS_NAMExx 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.

m_topology
    Like m_topology_inuse, except that it represents the architecture, not the use of it, i.e. it doesn't contain lower case letters.

m_socket
    Number of sockets available on the reporting host (e.g. "SCCSCCSCCSCC" => m_socket=4)

m_core
    Number of cores reported for all sockets on a host (e.g. "SCCSCCSCCSCC" => m_core=2)

m_thread
    Number of hardware threads reported for all cores on a host, which should be equal to num_proc (e.g. "SCTTCTTCTTCTT" => m_thread=8)

  Static Load Values
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.
