Re: [OMPI users] mpijavac doesn't compile any thing

[Howard Pritchard]

Hello Ibrahim

As a sanity check, could you try to compile the Hello.java in examples?

mpijavac --verbose Hello.java

you should see something like:

/usr/bin/javac -cp
/global/homes/h/hpp/ompi_install/lib/mpi.jar:/global/homes/h/hpp/ompi_install/lib/shmem.jar
Hello.java

You may also want to double check what your java env. variables, e.g.
JAVA_HOME, JAVA_ROOT, and JAVA_BINDIR

are set to.

[OMPI users] Buffer allocation at startup

[Erik Schnetter]

I want to set process affinity at startup. Currently, I do this after
calling MPI_Init. I have the suspicion that MPI_Init already allocates
communication buffers, which may thus be allocated on the wrong socket. Is
this indeed a problem? Is there a way to avoid this?

[OMPI users] mpijavac doesn't compile any thing

[Ibrahim Ikhlawi]

Hello,

I am trying to compile java classes with mpijavac, but it doesn't compile any 
class, for examle:
Usually when I write the following line (mpijavac MyClass.java) in the console, 
it compiles and gives me the possible errors (e.g. missed semicolon) and the 
.class file will be created.

But now when I compile any class with the same command (mpijavac 
AnyClass.java), it doesn't give me any error and the file AnyClass.class will 
be not created. 

What could be the problem?

Thanks in advance
Ibrahim

  

Re: [OMPI users] openmpi 1.8.8: Problems with MPI_Send and mmap:ed buffer

Did anyone take notice of this?

I haven't seen any respons.

Hi!

The attached code shows a problem when using mmap:ed buffer with
MPI_Send and vader btl.

With OMPI_MCA_btl='^vader' it works in all cases i have tested.


Intel MPI also have problems with this, failing to receive the complete
data, getting a NULL at position 6116 when the receiver is on another node.

(Haven't had time to build 1.10 yet...)
