exception easybuild.tools.systemtools.SystemToolsException¶

Bases: exceptions.Exception

raised when systemtools fails

easybuild.tools.systemtools.check_os_dependency(dep)¶: Check if dependency is available from OS.

easybuild.tools.systemtools.det_parallelism(par=None, maxpar=None)¶: Determine level of parallelism that should be used. Default: educated guess based on # cores and ‘ulimit -u’ setting: min(# cores, ((ulimit -u) - 15) / 6)

easybuild.tools.systemtools.det_terminal_size()¶: Determine the current size of the terminal window. :return: tuple with terminal width and height

easybuild.tools.systemtools.get_avail_core_count()¶: Returns the number of available CPUs, according to cgroups and taskssets limits

easybuild.tools.systemtools.get_core_count()¶: NO LONGER SUPPORTED: use get_avail_core_count() instead

easybuild.tools.systemtools.get_cpu_architecture()¶

Try to detect the CPU architecture

Returns:	a value from the CPU_ARCHITECTURES list

easybuild.tools.systemtools.get_cpu_family()¶: Determine CPU family. :return: a value from the CPU_FAMILIES list

easybuild.tools.systemtools.get_cpu_model()¶: Determine CPU model, e.g., Intel(R) Core(TM) i5-2540M CPU @ 2.60GHz

easybuild.tools.systemtools.get_cpu_speed()¶: Returns the (maximum) cpu speed in MHz, as a float value. In case of throttling, the highest cpu speed is returns.

easybuild.tools.systemtools.get_cpu_vendor()¶

Try to detect the CPU vendor

Returns:	a value from the CPU_VENDORS list

easybuild.tools.systemtools.get_gcc_version()¶: Process gcc –version and return the GCC version.

easybuild.tools.systemtools.get_glibc_version()¶: Find the version of glibc used on this system

easybuild.tools.systemtools.get_kernel_name()¶: NO LONGER SUPPORTED: use get_os_type() instead

easybuild.tools.systemtools.get_os_name()¶: Determine system name, e.g., ‘redhat’ (generic), ‘centos’, ‘debian’, ‘fedora’, ‘suse’, ‘ubuntu’, ‘red hat enterprise linux server’, ‘SL’ (Scientific Linux), ‘opensuse’, …

easybuild.tools.systemtools.get_os_type()¶: Determine system type, e.g., ‘Linux’, ‘Darwin’, ‘Java’.

easybuild.tools.systemtools.get_platform_name(withversion=False)¶: Try and determine platform name e.g., x86_64-unknown-linux, x86_64-apple-darwin

easybuild.tools.systemtools.get_shared_lib_ext()¶

Determine extention for shared libraries

Linux: ‘so’, Darwin: ‘dylib’

easybuild.tools.systemtools.get_system_info()¶: Return a dictionary with system information.

easybuild.tools.systemtools.get_tool_version(tool, version_option='--version')¶: Get output of running version option for specific command line tool. Output is returned as a single-line string (newlines are replaced by ‘; ‘).

easybuild.tools.systemtools.get_total_memory()¶

Try to ascertain this node’s total memory

Returns:	total memory as an integer, specifically a number of megabytes

easybuild.tools.systemtools.use_group(group_name)¶: Use group with specified name.
