mpirun并行运行问题
|
|
我在集群上运行一个软件,本意要求它一次同时运行两个任务,但是每次它都只是运行一个任务,软件的作者解释是如下,不知有没有大侠能否指点一下迷津.先行谢谢了. It appears that both mpi processes launched, but for some reason they launched independently of each other. This means that neither process was aware of the other process, so both processes were doing the same things. Both processes opened Test.inp and then tried to create this directory: /home/Test/Gaussian/bestSavedStructures One process succeded, and the other failed. The one that failed printed "Couldn't create log files directory." in the .e file and immediately stopped. The other kept going and made it to iteration 10, which was the predetermined stopping point. There didn't seem to be any problems with the disk which is very good. If you can figure out how to get the processes to see each other, you'll have a working program. Upon launch, each process prints it's rank (or index) and the total number of processes. This is what was printed during this run: This is MPI process with rank 0. Total MPI processes: 1 This is MPI process with rank 0. Total MPI processes: 1 This is what it should have printed: This is MPI process with rank 0. Total MPI processes: 2 This is MPI process with rank 1. Total MPI processes: 2 Please replace '-np 2' in pso.pbs with another option. You might try '-hostfile nodes.txt' or '-cpus-per-rank 1'. Or look at other options listed at http://www.open-mpi.org/doc/v1.4/man1/mpirun.1.php . Hope that helps! |
