SCORE7-BETA-1 RELEASE NOTE

    - X11 protocol relaying option of the scrun command is introduced.

    - The scratch command which adds line header so that users can see
      which process outputs the line is newly introduced.

    - The scan command to attach gdb is newly introduced. 

    - The papion command, which enables performance measurement via
      PAPI, is newly introduced.

    - The socut command now can work with ssh when the SCORE_RSH
      environment is set to ssh.

    - The configuration options for GLUT and PAPI are newly added.

    - PMX device option can be specified with the network option of
      the scrun command.

    - SCore-D system call bug is fixed and the job invokation speed is
      dramatically improved.

    - MPICH2/Nemesis/SCore termination bug is fixed.

    - The bug of XON-XOFF protocol, which can be seen when large
      amount of standard and error messages are output, is fixed.


SCORE7-BETA-0 RELEASE NOTE

    This SCore7-beta release has some missing features from the final
    target of SCore7. Here is the list of scheduled features.

    * Checkpoint and Restart

    * One-sided communication

    * Gang scheduling

    * Tight coupling with the third party batch schedulers.

    * File staging

    * PMX/TCP

    * Performance tuning

    The final target of full-featured SCore7 is the end of March, 2009.


MAJOR CHANGES FROM SCORE 6

    - The SCore's low-level communication library is now called PMX
      having new API. The performance problem on a multi-core system
      is dramatically improved.

    - Infiniband, Myrinet(2G), Myri10G are supported as well as
      Ethernet. 

    - There are two PMX implementations with Ethernet, PMX/Ethernet
      and PMX/EtherHXB. The former is a stable one and the latter is 
      experimental one at this moment but having higher performance.

    - SCore7 has two MPICH2 implementations, libmtmi and nemesis.

    - The mpi-selector command is enabled and you may choose one of
      SCore MPI implementations or any other MPI implementations.

    - SCore7 now has the man pages. The scorer command is the man page 
      command dedicated for SCore.

    - You can specify not only the allocation of process and core but
      also the allocation of process(es) and CPU socket.

    - The scrun command now supports of invoking two or more programs
      in a parallel job in the way of the mpirun commands. For
      example, "scrun a.out : b.out." 

    - No need of restarting scoreboard daemon process when you change
      scorehosts.db file.  

    - Network configuration files, such as pm-ethernet.conf, are no
      longer needed.

    - No file staging takes place in this beta version and the
      executable binary file must be located on an NFS volume.

    - In the scout command, the output from the compute hosts is 
      not only merged but also sorted or reverse-sorted.

    - The command to monitor the activity of user job in real-time is
      now called "scope" and you can attach monitor(s) whenever you
      want. 

    - Lots of bug fixes and enhancements.
