Java openmpi

Question

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?

Answer 1

Have a look on MPJ

You can read this section in Wikipedia.

Answer 2

I looked into MPJ a while back although its still in beta its looks fairly good and is still being developed. You mentioned that this does not work on the OSX checking the documentation there is a section that covers getting it working:-

PPC32 Mac OS X

  a. Edit $MPJ_HOME/bin/mpjboot and $MPJ_HOME/bin/mpjhalt
  b. Comment the line ssh $host "cd $MPJ_HOME/bin;./mpjdaemon_linux_x86_32 start;"
  c. Uncomment the line #ssh $host "cd $MPJ_HOME/bin;./mpjdaemon_macosx_ppc_32 start;"
  d. cd $MPJ_HOME/lib
  e. cp libwrapper.jnilib_macosx_ppc_32 libwrapper.jnilib
