在4个以上的进程上运行离散网格投影

Question

目前，我的模型在4个进程上以离散网格投影方式运行。我创建网格的方式如下：

    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。我试图将它保持在每个轴上，因为它最初是这样的，但是在第一个网格balance()调用之后，会导致以下错误

===================================================================================
=   BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
=   PID 71163 RUNNING AT Aleksandars-MBP
=   EXIT CODE: 11
=   CLEANING UP REMAINING PROCESSES
=   YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
===================================================================================
YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault: 11 (signal 11)

Answer 1

维度应与进程的数量相乘。所以，4x2代表8，4x4代表16。
