SCore Cluster System Software Release Note

The SCore 6.0.0 binary distribution is for CentOS 4.4

The SCore 6.0.0 binary distribution provides only the RPM files for CentOS 4.4. The distribution in RPM files includes the MPI libraries for Fujitsu compiler, Intel compiler version 8 and PGI compiler. If you want to use SCore 6.0.0 on any other Linux OSes and/or distributions, you must build SCore 6.0.0 form source codes.

New Features in SCore 6.0.0

1. New Checkpoint Facility
   The new checkpoint facility called CRT (Checkpoint/Restart for Threads) supports the checkpoint of a multi-threaded and/or dynamically linked application.

2. No kernel patch
   SCore has required the Linux kernel path in the previous SCore distributions. SCore 6.0.0 does not require any kernel patches. All kernel functions realized in SCore are implemented as kernel modules.

3. YAMPI MPI Communication Library
   In addition of MPICH1.2.5, YAMPI MPI Communication Library is supported.

4. Auto Configuration Tool
   A tool to provide the dynamic compute host configuration. The tool manages the SCore-D database so that the compute host list is dynamically maintained.

5. Dynamic Reconfiguration Tool
   In the SCore-D multi user mode, a compute host is dynamically joined or leaved. For more information, please look at the SCore-D "-daemon" option described in the man page

6. Easy Installation Tool, EIT Version 2.0
   The GUI based SCore installation tool comes back !
