Um conjunto de nós de feedback (FNS) de um gráfico é um subconjunto dos nós do gráfico cuja exclusão torna o gráfico residual acíclico. Ao encontrar um FNS em uma rede de interconexão, podemos definir um ponto de verificação em cada nó dela para evitar uma configuração de livelock. Portanto, encontrar um FNS é uma questão crítica para aumentar a confiabilidade de um sistema de computação paralelo. Neste artigo, propomos um método para encontrar SAN em n-gráficos de panqueca e ngráficos de panqueca queimada. Analisando os tipos de ciclos propostos em nosso método, damos também o número de nós do FNS em um n- gráfico de panqueca, (n-2.875)(n-1)!+1.5(n-3)!, e isso em um n- gráfico de panqueca queimada, 2n-1(n-1)!(n-3.5).

Abstract: A feedback node set (FNS) of a graph is a subset of the nodes of the graph whose deletion makes the residual graph acyclic. By finding an FNS in an interconnection network, we can set a check point at each node in it to avoid a livelock configuration. Hence, to find an FNS is a critical issue to enhance the dependability of a parallel computing system. In this paper, we propose a method to find FNS's in n-pancake graphs and n-burnt pancake graphs. By analyzing the types of cycles proposed in our method, we also give the number of the nodes in the FNS in an n-pancake graph, (n-2.875)(n-1)!+1.5(n-3)!, and that in an n-burnt pancake graph, 2n-1(n-1)!(n-3.5).

AB - A feedback node set (FNS) of a graph is a subset of the nodes of the graph whose deletion makes the residual graph acyclic. By finding an FNS in an interconnection network, we can set a check point at each node in it to avoid a livelock configuration. Hence, to find an FNS is a critical issue to enhance the dependability of a parallel computing system. In this paper, we propose a method to find FNS's in n-pancake graphs and n-burnt pancake graphs. By analyzing the types of cycles proposed in our method, we also give the number of the nodes in the FNS in an n-pancake graph, (n-2.875)(n-1)!+1.5(n-3)!, and that in an n-burnt pancake graph, 2n-1(n-1)!(n-3.5).
