Is there a current Java openmpi implementation. I have programmed in MPI a bit, and I enjoy programming in Java. I have seen this implementation in java, but it seems dated. Is there a more up to date java implementation that is being kept up? ...
Is there a way to run a local mpi job locally on os X leopard(10.5.6) with more than 62 processes. When I run the job with 62 processes, it dies $mpirun -np 62 a.out mpirun noticed that job rank 0 with PID 0 on node Macintosh-001D4F4BC6BC.private exited on signal 15 (Terminated). 60 additional processes aborted (not shown) and when...
I have been working with some friends to convert a Matlab Genetic Algorithm to C++ and it works in a sequential order currently. Matlab is no longer a portion of our current code. We are looking to use it on a cluster, but have been a little dry on resources. We have a cluster available at the University and it is equipped with Rocks ...
Hi, I have a program, that is been implemented in C++, now I want to add MPI support. The point is exist a MPI bind for C++, with namespace MPI and everything. In my case I have a specific object that is suitable to be the parallelized process into the cluster. Question, does anyone already did something like this ? Can give some advic...
Hi, I have a problem about a simple mpi program.This program have some 3D points and these points are moving during the program. I created an simple code by implemented c++ and then I tried to add an simple gui. I used gnuplot library and I have a problem. When I call the gui function the gui is created and it is disappeared at the same ...
If I had a single server and I had two process types A(Many processes many threads) and B(one process n-threads with n-cpu's), and I wanted to send a LARGE amount of one-way messages from A to B. Is MPI a better implementation for this than a custom implementation using: Unix Domain Sockets Windows Named Pipes Shared Memory I was thi...
Greetings , I have a little experience with SungridEngine and MPI (using OpenMPI). Whats the different between these frameworks/API and JPPF ? ...
Hi, (1). I am wondering how I can speed up the time-consuming computation in the loop of my code below using MPI? int main(int argc, char ** argv) { // some operations f(size); // some operations return 0; } void f(int size) { // some operations int i; d...
Hi, I am learning OpenMPI on a cluster. Here is my first example. I expect the output would show response from different nodes, but they all respond from the same node node062. I just wonder why and how I can actually get report from different nodes to show MPI actually is distributing processes to different nodes? Thanks and regards!...
Hello, I am trying to write a program which runs using OpenMPI on our cluster and communicates the results using TCP/IP to another machine which has a network connection to the cluster. I am using Boost.Asio for the TCP/IP connection. The problem I am facing is that if I remove the OpenMPI from the executable and compile it with g++ it ...
I'm thinking of slowly picking up Parallel Programming. I've seen people use clusters with OpenMPI installed to learn this stuff. I do not have access to a cluster but have a Quad-Core machine. Will I be able to experience any benefit here? Also, if I'm running linux inside a Virtual machine, does it make sense in using OpenMPI inside a ...
Hey all - I'm writing an MPI program (Visual Studio 2k8 + MSMPI) that uses Boost::thread to spawn two threads per MPI process, and have run into a problem I'm having trouble tracking down. When I run the program with: mpiexec -n 2 program.exe, one of the processes suddenly terminates: job aborted: [ranks] message [0] terminated [1] ...
Can someone elaborate the differences between the OpenMPI and MPICH implementations of MPI ? Which of the two is a better implementation ? ...
When attempting to run the first example in the boost::mpi tutorial, I was unable to run across more than two machines. Specifically, this seemed to run fine: mpirun -hostfile hostnames -np 4 boost1 with each hostname in hostnames as <node_name> slots=2 max_slots=2. But, when I increase the number of processes to 5, it just hangs. ...
I am following instructions at http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.config trying to build Boost MPI .lib files, but I got one problem: I do not have mpic++. Looking at the MPI implementation files such as MPICH2 and Open MPI, I see no mpic++ included at all. Where can I find mpic++? ...
Hi there. I'm trying to build a simple cluster based on Windows XP. I compiled OpenMPI-1.4.2 successfully, and tools like mpicc and ompi_info work too, but I can't get my mpirun working properly. The only output I can see is Z:\>orterun --hostfile z:\hosts.txt -np 2 hostname [host0:04728] Failed to initialize COM library. Error code =...
Hi there, I've written some MPI code which works flawlessly on large clusters. Each node in the cluster has the same cpu architecture and has access to a networked (i.e. 'common') file system (so that each node can excecute the actual binary). But consider this scenario: I have a machine in my office with a dual core processor (intel)...
A few minutes ago I stumbled upon some text, which reminded me of something that has been wondering my mind for a while, but I had nowhere to ask. So, in hope this may be the place, where people have hands on experience with both, I was wondering if someone could explain what is the difference between OpenMP and MPI ? I've read the Wik...
I have a C-code for parallel computing written for gcc, and I want to compile it on a cluster, which apparently uses icc via mpicc. Correcting the code to be icc-friendly seems to be too time-demanding, so I wonder if I can ask OpenMPI to use gcc instead. I don't have the admin rights on that cluster, and I would actually prefer to do no...
I am a newbie who tries to compile a program via mpicc replacing icc with gcc. I have already discovered, that I need to use the following command to compile $ OMPI_CC=gcc make However, I get the following error message (which is well-known) /opt/intel/fce/9.1.036/lib/libimf.so: warning: warning: feupdateenv is not implemented and wi...
