在4个以上进程上运行离散网格投影

Question

我的模型目前在4个进程上运行离散网格投影。我以以下方式创建网格：

std::vector<int> processDimensions;
processDimensions.push_back(2);
processDimensions.push_back(2);
// The grid projection will contain agents of type VirusCellInteractionAgents, so that it can facilitate all agents types
// Then we can use the agent type identifier in each agent ID, to cast them to the correct type of agent.
discreteGridSpace = new repast::SharedDiscreteSpace<VirusCellInteractionAgents, repast::WrapAroundBorders, repast::SimpleAdder<VirusCellInteractionAgents>>("AgentsDeiscreteSpace", gridDimensions, processDimensions, 2, comm);

我想尝试在8或16个进程上运行该模型，所以我想知道，在这种情况下processDimensions应该是什么。我试图在每个轴上保持2，就像最初一样，但这导致了在第一次网格平衡((调用之后出现以下错误

===================================================================================

Answer 1

维度应该乘以进程的数量。所以，4x2换8，4x4换16。
