repast-hpc - 在超过 4 个进程上运行离散网格投影

Question

我目前的模型在 4 个进程上运行离散网格投影。我通过以下方式创建网格：

    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 个进程上运行模型，所以我想知道，在这种情况下 processDimensions 应该是什么。我尝试像最初一样在每个轴上保持 2，但是在第一次 grid balance() 调用之后导致以下错误

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

Answer 1

维度应乘以进程数。因此，8 的 4x2 或 16 的 4x4。
