在LAM/MPI群集上安装Rmpi

Question

我正在尝试Rmpi在LAM MPI集群机器上安装软件包.以前我一直在编译和测试一些东西(mpi4py和小型C++程序),所以我确信MPI本身是有效的.但是Rmpi,链接库时安装包失败.

我的主要嫌疑人是调用gcc而不是mpicc在makefile中(我试图找到配置中的行来改变它,但到目前为止找不到它).

有人有在LAM上安装Rmpi的经验,你是如何管理的？

建筑

• LAM MPI(如果存在,也可能是PBS MPI,如何检查？).有一件事是肯定的,我有mpicpp文件,我认为并不是所有的mpi实现都很常见
• R-2.15.2
• Rmpi_0.6-1
• CentOS版本5.5(最终版),x86_64

从R调用的命令

install.packages("Rmpi")

我们有一个非常相似的设置.我最近没有触及它以便能够说出你的具体情况,但我可以传递一些使我们正常运行的命令......

正如Dirk所说,我们的第一步是让OpenMPI运行.设置完成后,您需要确保LD_LIBRARY_PATH正确设置:

export LD_LIBRARY_PATH=/opt/openmpiv2/lib/:$LD_LIBRARY_PATH

最终为我们安装了Rmpi的命令(在运行上述命令并启动R之后)是:

install.packages("Rmpi", configure.args = c("--with-Rmpi-include=/opt/openmpiv2/include/", "--with-Rmpi-libpath=/opt/openmpiv2/lib/", "--with-Rmpi-type=OPENMPI", "--with-mpi=/opt/openmpiv2/"))

哪个为我们成功安装了包.然后我们可以使用以下命令运行作业:

qsub -I -l nodes=2:ppn=12
/opt/openmpiv2/bin/mpirun --hostfile $PBS_NODEFILE -n 1 R --slave -f rmpitest.R

这些命令可能特定于我们的设置,它们可能没用,但希望这里的东西可以节省你一些时间!

正如@Sergej在下面提出的,更通用的解决方案可能是:

install.packages(
  "Rmpi", 
  configure.args = c(
   "--with-Rmpi-include=/usr/include/", # This is where LAM's mpi.h is located
   "--with-Rmpi-libpath=/usr/lib/",     # This is where liblam.so is located (actually as I type it mine was located in /usr/lib64/liblam.so.0, so maybe this is not needed at all)
   "--with-Rmpi-type=LAM"               # This says that the type is LAM (there is also OPENMPI and MPICH)
))

我们的设置:RHEL 5,Rmpi 0.5-9,OpenMPI 1.4.3.,R 2.15.0
