7 Diagnostic messages of the dynamic debugger
Table 1. The messages of dynamic control of DVM-directives
Error message |
Description |
| Writing to read-only variable <var> | Writing to read-only variable is detected. |
| Using non-initialized variable <var> | Access to non-initialized variable is detected. |
| Using non-initialized element <elem> | Access to non-initialized array element is detected. |
| Using variable <var> before asynchronous reduction competed | Access to reduction variable before reduction operation completion is detected. |
| Access to non-local element <elem> | Access to non-local element of distributed array is detected. |
| Writing to shadow element <elem> of array | Writing to shadow element of array is detected. |
| Data dependence in loop due to access to element <elem> | Data dependence in parallel loop is detected. |
| Using shadow element <elem> before asynchronous shadow renew competed | The dynamic debugger detects access to a shadow element before asynchronous shadow renew competed |
| Writing to remote data buffer <var> | Writing to remote data buffer is detected. |
| Write to remote element <elem> in sequential branch | Access to array element in sequential branch of program without preliminary testing that the element is located on current processor. |
| Reading remote element %s in sequential branch | Access to non-local array element in sequential branch of program is detected. |
| WAIT for reduction without START | Waiting for asynchronous reduction completion is issued without Start asynchronous reduction. |
| Using element outside of array limits: <elem> | Access to element of array beyond its limits. |
| START for reduction without WAIT | The wait operation is missing for started asynchronous reduction calculation. |
| Reduction operation was not started | The reduction variable is specified but the reduction calculation is never performed. |
Table 2. The messages of comparing execution results
Error message |
Description |
| Bad file structure | It is reported when any non-correspondence of trace or loop description file is detected. |
| Undefined keyword | It is reported if unknown keyword appears in trace or loop description file. |
| Bad command syntax | It is reported, if wrong parameters appear after keyword. |
| Can't open a file <file name> | Specified file can’t be open on reading or writing. |
| Trace file is empty | Specified trace file exists, but it is empty. |
| Bad trace structure (missing current program construct) | It is reported, if iteration or task beginning or structure completion event occurs without correspondent structure beginning event. |
| No current program construct | It is reported if iteration or task beginning or structure completion event occurs without corresponding structure beginning event. |
| Unexpected task or iteration of loop | It is reported if iteration or task beginning event occurred, but there is no correspondent record in reference trace. |
| Double execution of task or iteration, No = <iteration number> | It is reported if iteration or task beginning event occurs for already executed loop iteration or task. Absolute iteration number is reported. |
| Unexpected execution of program construct | It is reported if structure beginning event occurs, but there is no correspondent record in reference trace. |
| Abnormal loop exit | It is reported if record of loop end is not corresponds to the record of loop beginning. |
| Unexpected use of variable | It is reported if there is no record in reference trace for variable access event. |
| Unexpected trace record | It is reported if there is no record in reference trace for an event of completion of self-calculation block in the sequential branch. |
| Different <type> values: <standard value> != <current value> | Different values of the same variable are detected for current event and in reference trace record. |
| Different <type> values of reduction variable: <standard value> != <current value> | Different values of reduction operation are detected for current event and in reference trace record. |
