Hi,
I also reproduce this behaviour. But I think this crash is not related

May be MPI corrupts the Java runtime heap.

Hi,
There is an error in the program.
First you declare a 256 char buffer (BUF_SIZE = 256).
When it is executed the line 96:
buffer = (MPI.getProcessorName()).toCharArray();
The buffer length becomes less than 256.
So, when the next iteration is executed, at line 92 you could get an

Hi Takahiro, Gilles, Siegmar,
Thank you very much for all your fix.
I don't notice about calling 'mca_base_var_register' before MPI_Init.
I'm sorry for the inconvenience.

Kawashima-san,
thanks a lot for the detailled explanation.
Hello Siegmar,
If your Java program only calls to MPI.Init and MPI.Finalize you don't
need debug Java. The JNI layer is very thin, so I think the problem is
not in Java. Also, if the process crash is in the JNI side, debugging
won't provides you useful information.
But if you want debug 2 pr
Hello Atsugua,
You can only send contiguous data, i.e. arrays of basic datatypes (byte,
char, short, boolean, int, long, float and double) or direct buffers. If
you need to send complex data, then you must serialize into an array or
a direct buffer. This is made using using the mpi.Struct clas
s the matrix size is increased.
Thank you,
Saliya

Copy the 2D matrix to the buffer:
for(int i = 0; i < m; i++)
System.arraycopy(matrix[i], 0, buffer, i * n, n);
Copy from the buffer to the 2D matrix:

Hi,
I've a quick question about the usage of Java binding.
Say there's a 2 dimensional double array (size m x n) that needs to be
sent to another rank. I see two options to get this done,
1. Copy values to a direct buffer of size m*n and send it
I'm sorry but I can not reproduce the problem.
I recompiled all from scratch using Java 8, and it works ok on Debian 7.5.

Hi Madhurima,
Currently we only have tests which start MPI and check the provided

Hi,
If you are talking about types as ArrayList, it is not
possible, because the Double (D uppercase) is an object which
encapsulates a double. And the elements of an ArrayList are references
(pointers) to Java objects.
You can use complex types but you must create them with the Datatype
Jeff added a jdoc target in '~/ompi-java/ompi/mpi/java/java/Makefile.am'.
Javadoc is created in '~/ompi-java/ompi/mpi/java/java/doc'
I think javadoc could be created if you select '--enable-mpi-java',
and it could be copied in '~/ompi-install/share/javadoc'.
