Data Types | |
| interface | m_cpuid_static |
| Target architecture or instruction set extension according to compiler target flags. More... | |
| interface | m_omp_trace_issues |

Functions/Subroutines | |
| subroutine, public | m_flush (lunit) |
| flushes units if the &GLOBAL flag is set accordingly | |
| real(kind=dp) function, public | m_walltime () |
| returns time from a real-time clock, protected against rolling early/easily | |
| subroutine, public | m_cpuinfo (model_name) |
| reads /proc/cpuinfo if it exists (i.e. Linux) to return relevant info | |
| pure integer function, public | m_cpuid () |
| Target architecture or instruction set extension according to CPU-check at runtime. | |
| pure character(len=default_string_length) function, public | m_cpuid_name (cpuid) |
| Determine name of target architecture for a given CPUID. | |
| pure integer function, public | m_cpuid_vlen (cpuid, typesize) |
| Determine vector-length for a given CPUID. | |
| real(kind=dp) function, public | m_energy () |
| returns the energy used since some time in the past. The precise meaning depends on the infrastructure is available. In the cray_pm_energy case, this is the energy used by the node in kJ. | |
| subroutine, public | m_timestamp (timestamp) |
| Returns a human readable timestamp. | |
| subroutine, public | m_abort () |
| Can be used to get a nice core. | |
| integer function, public | m_procrun (pid) |
| Returns if a process is running on the local machine 1 if yes and 0 if not. | |
| subroutine, public | m_memory (mem) |
| Returns the total amount of memory [bytes] in use, if known, zero otherwise. | |
| subroutine, public | m_memory_details (memtotal, memfree, buffers, cached, slab, sreclaimable, memlikelyfree) |
| get more detailed memory info, all units are bytes. the only 'useful' option is MemLikelyFree which is an estimate of remaining memory assumed to give info like /proc/meminfo while MeMLikelyFree is the amount of memory we're likely to be able to allocate, but not necessarily in one chunk zero means not available... | |
