     411=== Survey ===
     412Survey the application to determine hotspots. Typically an optimized
     413 (non-debug) version of the application is used when surveying an application.
     414
     415Run and Collect info.
     416{{{#!bash
     417$ icc -g -O3 mycode.c
     418$ advixe-cl --collect survey --project-dir ./advi ./a.out
     419}}}
     420
     421Show report
     422{{{#!bash
     423$ advixe-cl --report survey --project-dir ./advi ./a.out
     424}}}
     425
     426=== Add Annotations ===
     427Add annotations to the application source code, and rebuild the application.
     428 Please see the Getting Started Tutorial for more information.
     429
     430For C/C++
     431{{{#!c
     432#include "advisor-annotate.h"
     433.....
     434    ANNOTATE_SITE_BEGIN(sitename1);
     435    for ( ....
     436    {
     437        ANNOTATE_TASK_BEGIN(taskname1);
     438        ...
     439        ANNOTATE_TASK_END();
     440    }
     441    ANNOTATE_SITE_END();
     442}}}
     443
     444Fortran
     445{{{#!fortran
     446use advisor_annotate
     447.....
     448call annotate_site_begin(sitename1)
     449do .....
     450    call annotate_task_begin(taskname1)
     451    ....
     452    call annotate_task_end()
     453enddo
     454call annotate_site_end()
     455}}}
     456
     457=== Suitability ===
     458Collect suitability data. Note that annotations must be present in the source
     459 code for this collection to be successful. Typically an optimized (non-debug) version
     460 of the application is used when collecting suitability data.
     461{{{#!bash
     462$ icc -g -O3 mycode.c
     463$ advixe-cl --collect suitability --project-dir ./advi ./a.out
     464}}}
     465
     466{{{#!bash
     467$ advixe-cl --report suitability --project-dir ./advi ./a.out
     468}}}
     469
     470
     471=== Correctness ===
     472Collect correctness data. Note that annotations must be present in the source
     473 code for this collection to be successful. Typically an application with debug symbols
     474 is used when collecting correctness data.
     475
     476{{{#!bash
     477$  icc -g -O0 mycode.c
     478$ advixe-cl --collect correctness --project-dir ./advi ./a.out
     479}}}
     480
     481{{{#!bash
     482$ advixe-cl --report correctness --project-dir ./advi ./a.out
     483}}}
     484
     485Display a list of annotations present.
     486{{{#!bash
     487advixe-cl --report annotations --project-dir ./advi ./a.out
     488}}}
     489Update the application using the chosen parallel coding constructs. Rebuild the application and test.
