MPI_Comm_spawn:新进程是按顺序创建还是同时创建?
我想知道 mpi_comm_spawn 操作是否会顺序创建指示的过程数(例如,一个接一个)或同时创建。我正在使用MPICH实现。
我正在研究一个在过程级别执行延展性的代码,并且我想知道该操作如何执行过程创建(以了解开销是否取决于更多参数,例如流程的数量以及它们的创建方式)。我找不到有关它的信息。也许有更多经验的人知道这一点。
谢谢。
I want to know if the MPI_Comm_spawn operation creates the number of processes indicated sequentially (e.g. one after another) or simultaneously. I am using MPICH implementation.
I'm working on a code that performs malleability at a process level, and I want to know how this operation performs the processes creation (to understand if the overhead depends on more parameters, like the number of processes and how they are created). I can't find information about it. Maybe someone with more experience knows it.
Thank you.
