효과적인 시각화는 일반적으로 대용량의 디버깅 정보와 프로그램의 추상적 수행모델을 표현하는 것이 중요하다. 본 논문에서는 스레드들간의 논리적 병행성 관계를 나타내는 부분순서 수행그래프를 이용하여 내포병렬성과 임계구역을 가진 OpenMP 병렬 프로그램의 수행양상과 경합정보의 효과적 디버깅을 위해서 효과적으로 제공하는 추상적 시각화 도구를 제안한다. 본 도구는 수행중 추적선택 기법으로 시각화 정보를 위한 공간적 복잡성을 줄이고, 추적된 시각화 정보에 프로그램의 내포병렬성과 임계구역 동기화를 위한 그래프 추상화를 제공하여 시각적 복잡성을 해결한다. 그래프 추상화를 통한 스레드들간의 부분순서 관계와 경합탐지 정보는 프로그램의 제어흐름과 경합의 위치를 구조적으로 파악할 수 있게 하므로 프로그램 수행의 이해와 경합 탐지 및 수정에 효과적이다.
