- Operating System
- This program is extensively tested and known to work on,
- Red Hat Enterprise Linux Server release 5.10 (Tikanga)
- Ubuntu 12.04.3 LTS
- Ubuntu 12.10
- This may work in Windows systems depending on the ability to setup OpenMPI properly, however, this has not been tested and we recommend choosing a Linux based operating system instead.
- Download Oracle JDK 8 from http://www.oracle.com/technetwork/java/javase/downloads/index.html
- Extract the archive to a folder named
- Set the following environment variables.
JAVA_HOME=<path-to-jdk1.8.0-directory> PATH=$JAVA_HOME/bin:$PATH export JAVA_HOME PATH
- Apache Maven
- Download latest Maven release from http://maven.apache.org/download.cgi
- Extract it to some folder and set the following environment variables.
MVN_HOME=<path-to-Maven-folder> $PATH=$MVN_HOME/bin:$PATH export MVN_HOME PATH
- Habanero Java (HJ) Library
- Download HJ-lib jar file from http://www.cs.rice.edu/~vs3/hjlib/code/habanero-java-lib-0.1.1.jar
- Execute the following shell command from the directory containing the HJ-lib jar to install it as a Maven artifact
mvn install:install-file -DcreateChecksum=true -Dpackaging=jar -Dfile=habanero-java-lib-0.1.1.jar -DgroupId=habanero-java-lib -DartifactId=habanero-java-lib -Dversion=0.1.1;
- Find more information about HJ-lib at https://wiki.rice.edu/confluence/display/PARPROG/Download+and+Set+Up
- We recommend using
OpenMPI 1.8.1although it works with the previous 1.7 versions. The Java binding is not available in versions prior to 1.7, hence are not recommended. Note, if using a version other than 1.8.1 please remember to set Maven dependency appropriately in the
- Download OpenMPI 1.8.1 from http://www.open-mpi.org/software/ompi/v1.8/downloads/openmpi-1.8.1.tar.gz
- Extract the archive to a folder named
- Also create a directory named
buildin some location. We will use this to install OpenMPI
- Set the following environment variables
BUILD=<path-to-build-directory> OMPI_181=<path-to-openmpi-1.8.1-directory> PATH=$BUILD/bin:$PATH LD_LIBRARY_PATH=$BUILD/lib:$LD_LIBRARY_PATH export BUILD OMPI_181 PATH LD_LIBRARY_PATH
- The instructions to build OpenMPI depend on the platform. Therefore, we highly recommend looking into the
$OMPI_181/INSTALLfile. Platform specific build files are available in
- In general, please specify
--enable-mpi-javaas arguments to
configurescript. If Infiniband is available (highly recommended) specify
--with-verbs=<path-to-verbs-installation>. In summary, the following commands will build OpenMPI for a Linux system.
cd $OMPI_181 ./configure --prefix=$BUILD --enable-mpi-java make;make install
- If everything goes well
mpirun --versionwill show
mpirun (Open MPI) 1.8.1. Execute the following command to instal
$OMPI_181/ompi/mpi/java/java/mpi.jaras a Maven artifact.
mvn install:install-file -DcreateChecksum=true -Dpackaging=jar -Dfile=$OMPI_181/ompi/mpi/java/java/mpi.jar -DgroupId=ompi -DartifactId=ompijavabinding -Dversion=1.8.1;
- Few examples are available in
$OMPI_181/examples. Please use
mpijavacwith other parameters similar to
javaccommand to compile OpenMPI Java programs. Once compiled
mpirun [options] java -cp <classpath> class-name argumentscommand with proper values set as arguments will run the program.
- Check all prerequisites are satisfied before building davs
- Clone this git repository from
email@example.com:DSC-SPIDAL/davs.gitLet's call this directory
- Once above two steps are completed, building davs requires only one command,
mvn install, issued within
The following shell script may be used with necessary modifications to run the program.
#!/bin/bash # Java classpath. This should include paths to davs dependent jar files and the davs-1.0-ompi1.8.1.jar # The dependent jar files may be obtained by running mvn dependency:build-classpath command within davshome cp=<classpath> # Obtain working directory wd=`pwd` # Character x as a variable x='x' # A text file listing available nodes hosts=<path-to-hostfile> # Number of nodes nodes=<num-nodes> # Number of cores per node corespernode=8 # Options for Java runtime jopts="-Xms64M -Xmx64M" # Number of threads to use within one davs process tpn=<threads-per-process> # Number of processes per node ppn=<processes-per-node> # Total parallelism expressed as a pattern TxPxN # where T is number of threads per process, P is processes per node, and N is total nodes pat=$tpn$x$ppn$x$nodes echo "Running $pat on `date`" >> status.txt # Invoke MPI to run davs mpirun --report-bindings --mca btl ^tcp --hostfile $hostfile --map-by node:PE=$(($corespernode / $ppn)) -np $(($nodes*$ppn)) java $jopts -cp $cp edu.indiana.soic.spidal.davs.Program -c config$pat.properties -n $nodes -t $tpn | tee $pat/davs-out.txt echo "Finished $pat on `date`" >> status.txt
The arguments listed in the
mpirun command fall into three categories.
- OpenMPI Runtime Parameters
--report-bindingsrequests OpenMPI runtime to output how processes are mapped to processing elements (cores) in the allocated nodes.
--mca btl ^tcpinstructs to enable transports other than tcp, which is useful when running on Infiniband.
--hostfileindicates the file listing available nodes. Each node has to be a in a separate line.
--map-by node:PE=$(($corespernode / $ppn))controls process mapping and binding. This is a topic on its own right, but the specific values in this example requests processes to be mapped by node while binding each to
corespernode/ppnnumber of processing elements. A good set of slides on this topic is available at http://www.slideshare.net/jsquyres/open-mpi-explorations-in-process-affinity-eurompi13-presentation
-np $(($nodes*$ppn))determines the total number of processes to run and in this case it is equal to
- Java Runtime Parameters
$joptsin this case lists initial and maximum heap sizes for a JVM instance.
-cpindicates paths to find required classes where each entry is separated by a
- Program (davs) Parameters
-cpoints to the configuration file. This is a Java properties files listing values for each parameter that davs requires. Details on these parameters will follow in a later section.
-nindicates the total number of nodes
-tdenotes the number of threads to use within one instance of davs
The following table summarizes the parameters used in davs.
We like to express our sincere gratitude to Prof. Vivek Sarkar and his team at Rice University for giving us access and continuous support for HJ library. We are equally thankful to Prof. Guillermo L�pez Taboada for giving us free unrestricted access to commercially available FastMPJ MPI library, which we evaluated in an earlier internal version. We are also thankful to FutureGrid project and its support team for their support with HPC systems. Last but not least OpenMPI community deserves equal recognition for their valuable support.
