I have problems with mpiJava (that use MPICH2 implementation).
 


Packing pixels of images with 11MB, the same program works very well, but using pixels of images with 21MB, it doesn't work correctly. 


With 3 pcs and 3 processes, it's Ok!  But with 3 pcs and 4 processes, occur the followings errors:





  






mpirun -np 4 java -Xmx300M Med21MB3x3


 


[cli_2]: aborting job:

This mailing list is for issues relating to the use of
LAM/MPI.  You  
should contact the MPICH2 support mailing list (it's on
their web  
page) for help with MPICH2.
