Question

我正在尝试在LAM MPI群集计算机上安装Rmpi包。以前我一直在编译和测试一些东西（mpi4py和小C ++程序），所以我确信MPI本身是有效的。但是，链接库时安装Rmpi包失败。

我的主要嫌疑人是在makefile中调用gcc而不是mpicc（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，你是如何管理它的？

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mpi实现都是通用的
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")

Answer 1

我们的设置非常相似。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。完成设置后，您需要确保LD_LIBRARY_PATH已正确设置：

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/"))

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

这些命令可能对我们的设置非常具体，以至于它们可能没什么用处，但希望这里的东西可以为您节省一些时间！

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

Answer 2

许多年前，我曾经使用过LAM，但之后转而使用OpenMPI。 Rmpi的作者郝宇建议做同样的事情。

r-sig-hpc列表是解决此类问题的理想场所。

Answer 3

根据杰夫艾伦的建议，我去了R并运行

install.packages(
  "Rmpi", 
  configure.args = c(
   "--with-Rmpi-include=/usr/include/", # This is where LAM's mpi.h is located
   "--with-Rmpi-libpath=/usr/lib64/",     # This is where liblam.so is located
   "--with-Rmpi-type=LAM"               # This says that the type is LAM (there is also OPENMPI and MPICH)
))

我也跑

# Because it was non-standard R location so it din't find shared libraries
export LD_LIBRARY_PATH=/g/software/linux/pack/r-2.15.0/lib64/R/lib

# Rmpi also could not find libutil so I had to add path to it as well
export LD_PRELOAD=/usr/lib64/libutil.so

修改

即使我在多个节点上运行Rmpi时设法编译它也失败了。所以我想我必须开始推动OpenMPI转换：/
