The parameters of dynamic control, presented below, are set in files with name usrdebug.

• EnableDynControl =1 - dynamic control is enable.

• EnableTrace =0 - trace processing is disable.

• EnableDynControl =0 - Dynamic control is disabled.

• EnableTrace =1 - Trace processing is enabled.

• DbgInfoPrint =1 - Flag to output information messages of dynamic control system and

• TraceOptions.TraceMode - specifying trace mode:

0 - generating loop description file. Only processor with the number TraceOptions.WrtHeaderProc writes to this file.

1 - accumulating trace and writing into the file <processor number>.<TraceOptions.Ext>.

2 - joining of the two previous modes.

3 - comparing the execution trace with the reference one, given in file TraceOptions.TraceFile.

• TraceOptions.TraceLevel - trace accumulation level. It is irrelevant in modes of trace accumulation and loop descriptor file generation only.

0 - trace is not accumulated.

1 - accumulating loops and iterations trace only.

1 - the previous level plus accumulating trace of variable modifications.

2 - accumulating full trace.

• ManualReductCalc - mode of reduction calculation. If flag is equal to 0, then the calculation mode is usual, and emulation of computation of each loop iteration at its own processor is performed in other case.

• TraceOptions.WriteEmptyIter -if flag is equal to 0 then the records, corresponding to iteration beginning, are excluded from trace, if inside the iteration there are no references to the variables or nested loops.

• TraceOptions.TracePath - path for trace files.

• TraceOptions.TraceFile - the name of the reference trace file. This file is looked for in the TraceOptions.TracePath directory. This parameter is used only in the trace comparison mode.

• TraceOptions.Ext - extension of accumulated trace files. The name of a trace file is formed as <processor number>.<TraceOptions.Ext>. The trace file will be created in the TraceOptions.TracePath directory. This parameter is used only in the trace accumulation mode.

• TraceOptions.FileLoopInfo - loop description file name. This file is searched in the TraceOptions.TracePath directory.

• TraceOptions.ErrorToScreen - if flag is not equal to 0 then all diagnostic messages will be output to the screen.

• TraceOptions.ErrorFile - the name of error diagnostic file. The file is used if parameter TraceOptions.ErrorToScreen is equal to 0. If system cannot open the file, the error messages will be output to the screen.

• TraceOptions.AppendErrorFile - the mode of a diagnostic file usage. The file will be cleared at each program startup, if the flag is equal to 0.

• TraceOptions.MaxErrors - the maximal count of errors after that the trace accumulation or comparing will be disabled.

• TraceOptions.PrintStatistic - Output statistics after program completion. The statistics is output to a file TraseOptions.ErrorFile or to the screen according to value of TraceOptions.ErrorToScreen parameter.

• TraceOptions.Exp - exactitude of a float number comparison in the trace-comparing mode.

• TraceOptions.WrtHeaderProc -. the number of a processor that forms loop description file. Since the common structure of the program is the same for all the processors, then loop description file will be identical for any process. The only distinction is the trace size, because these values are calculated only for the current process. The summary trace size estimation can be obtained by launching the program on a single processor.

• TraceOptions.SpaceIndent - the indent size used in the trace files

• TraceOptions.TableTraceSize - size of arrays for tracing.

• TraceOptions.HashIterIndex,
  TraceOptions.HashIterSize - hash-table parameters, used for searching iterations.

  TraceOptions.ReductVarTableSize - the parameters of the reduction variable-table, used for keeping reduction variables.

• TraceOptions.SaveThroughExec - the trace will be written into the file during program execution (there is no accumulating in memory) if this parameter is not equal to 0. Otherwise the trace will be accumulated in the memory and written after program completion.
