Hallo,
When I run my code for a big number of data with Java OpenMPI, I get the error
"java.lang.OutOfMemoryError", even if I run that on a server with 64GB RAM.
Also I need to maximize the size of the memory allocation.
With java I can do that by adding -Xmxn (write man java), but when I run my

Thank you,Saliya

Hallo,
I am working on a server and run java codes with OpenMPI. I want to know which
number of process is the fastest to run my code with?
For this reason I wrote a code that multiply two matrices but the differences
between the results is not significant.
Therefore I want to know how can I

If you'd like to post the java code to the list, I can try it out on some of
the servers I use.

Hallo,
I'm working with java OpenMPI on a server with 64GB memory. But when I run the

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.

Hello,
can any one give me a simple example how to multiply two matrices in java
openmpi ?
I can not understand the difference between if-clauses in openmpi, for example:
1- if-clause to check the master process (rank 0), then I send an array to
process 2 (rank 1).
2- if-clause to check if this
Hi,
what is the best way to multiply two matrices with java-openmpi.
Is the way in this link the right way to do that? Also split the first matrix
row wise and multiply each one with the second matrix (each row on a processor)
then collect the results.

Hi,
I am beginner in OpenMPI. I want to run some examples from the extracted

namely Hello.java and Ring.java.
But when I compile Hello.java with:
javac Hello.java
I get this error:
