NAME

load_parameters - Grid Engine default load parameters

DESCRIPTION

The load parameters reported by the execution daemon sge_execd(8) 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 ver‐ sions. 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 Grid Engine 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 uptime(1). 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 uptime(1). 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 uptime(1). 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 Grid Engine 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 Grid Engine 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 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. 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.
