<processor number>

- number of processor, where error occurred. It is outputted only if a program executes on several processors.

<context>

- context, where the error occurred.
It can be one of the following forms:

Sequential branch

- the error occurred in sequential part of the program

Loop( No(N₁), Iter(I₁,I₂,…)), …, Loop( No(N_m), Iter(I₁,I₂,…))

- the error occurred when m-dimensional loop was executed.

<file>

- name of file, where the error occurred.

<line>

- line number.

<count>

- a number of given error repetitions in the given context. It is output when all detected errors are reported.

<error message>

- error description message.

Writing to read-only variable <var>

Writing to read-only variable is detected.

Using non-initialized private variable <var>

Access to non-initialized variable is detected.

Using non-initialized element <elem>

Access to non-initialized distributed array element is detected.

Using variable <var> before asynchronous reduction competed

Access to reduction variable before reduction operation completion.

Access to non-local element <elem>

Access to non-local element of distributed array.

Writing to shadow element <elem> of array

Writing to shadow element of array.

Shadow element <elem> was not updated

Access to shadow elements before completion of shadow edge renewing operation.

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

Usage of shadow element <elem> of distributed array during shadow edge renewing operation execution.

Writing to remote data buffer <var>

Writing to remote data buffer <var>.

Write to remote element <elem> in sequential branch

Writing to distributed array element <elem> in sequential branch of the program without own computation specification.

Reading remote element <elem> in sequential branch

Using not local element <elem> of distributed array in sequensial branch of the program.

WAIT for reduction without START

Waiting for reduction completion is issued without the reduction start.

Using an element outside of array limits: <elem>

Access to element of array beyond its limits.

START for reduction without WAIT

Absence of waiting for asynchronous reduction completion operation for corresponding operation of asynchronous reduction start.

Reduction operation was not started

Reduction variable is specified, but corresponding computation of reduction operation was never started.

Error message

Description

Bad file structure

Trace file structure is incorrect.

Undefined keyword

Unknown keyword appears in trace file.

Bad command syntax

Wrong structure of trace record.

Can't open a file <file name>

Specified file can’t be opened.

Trace file <file name> is empty

Specified trace file is empty.

Bad trace structure (missing current program construct)

Trace file structure is incorrect. Record of executable construct beginning is missed.

No current program construct

Record of executable construct beginning is missed.

Unexpected task or iteration of loop

There is no record about given iteration or task execution in reference trace.

Double execution of task or iteration, No = <iter no>

Repeated execution of the same iteration or task.

Unexpected execution of program construct

There is no record about given loop or task execution in reference trace.

Abnormal loop exit

Loop end doesn't correspond to the record in reference trace.

Unexpected use of variable

There is no given variable usage record in reference trace.

Unexpected trace record

There is no given event performance record in reference trace.

Different <type> values: <standard value> != <current value>

Variable value differ from the variable value in reference traced.

Different <type> values of reduction variable: <standard value> != <current value>

Result value of reduction computation differ from the value in reference trace.
