Maui Trace File Format, version 310


    Maui supports a trace format for workload (jobs) and another for resources (nodes).

16.3  Workload Traces

    Workload traces fully describe all scheduling relevant aspects of batch jobs including resources requested and utilized, time of all major scheduling event (i.e., submission time, start time, etc), the job credentials used, and the job execution environment.  Each job trace is composed of a single line consisting of 44  whitespace delimited fields as shown in the table below.

16.2   Resource Traces

    Resource traces fully describe all scheduling relevant aspects of a batch system's compute resources.  In most cases, each resource trace describes a single compute node providing information about configured resources, node location, supported classes and queues, etc.  Each resource trace consists of a single line composed of 21 whitespace delimited fields.  Each field is described in detail in the table below.

Resource Type 1 one of COMPUTENODE COMPUTENODE currently the only legal value is 'COMPUTENODE'
Event Type 2 one of AVAILABLE, DEFINED, or DRAINED [NONE] when AVAILABLE, DEFINED, or DRAINED is specified, node will start in the state Idle, Down, or Drained respectively.
NOTE:  node state can be modified using the mnodectl command.
Event Time 3 <EPOCHTIME> 1 time event occurred.  (currently ignored)
