Attention:SCore 5.8.3 does NOT have binary compatibility with SCore 5.8.1 and before SCore 5.0.1.

The SCore 5.8.3 binary distribution is for Fedora Core 3

Attention: The SCore 5.8.3 binary distribution provides only the RPM files for Fedora Core 3. If you want to use SCore 5.8.3 on any other Linux OSes, you must build SCore 5.8.3 form source codes.

This distribution includes the MPI libraries for Fujitsu compiler, Intel compiler version 8 and PGI compiler.

SCore 5.8.3 does not include Easy Installation Tool.

New Features in SCore 5.8.3

  1. Linux Kernel 2.6.11 is supported.
  2. pmopt and rpmopt is added to query PM options.
  3. -noscwrap option is added to The compile drivers such as scorecc . If you specify this option, the compiler is not link scwrap library.
  4. Add PM/Ethernet driver without kernel patch (Experimental).

Bug Fixes

  1. llseek() wrapper bug is fixed.
  2. smake dose not make OMNI OpenMP programs is fixed.
  3. You can use /dev/stdin, /dev/stdout, /dev/stderr in your SCore program.
  4. Correct SCore program generated file permition.

Unsupported in SCore 5.8.3

  1. PM/Infiniband for TopSpin HCA is unsupported.

Limitation

  1. Remote DMA functions in PM/Ethernet is not worked on this version.

  2. IA64 porting

    We have not tested the following features in an IA64 cluster:

    1. Omni OpenMP

  3. AMD64 porting

    The following features in an AMD64 cluster are NOT tested:

    1. Omni OpenMP

    2. Remote DMA functions on Myrinet, Myrinet2K, MyrinetXP and Myrinet2XP

  4. PM/Infiniband for Fujitsu HCA

    A special HCA firmware dedicated to SCore is required. Ask Fujitsu to get the firmware.

  5. The PM/Ethernet trunking has only been tested on up to three Intel EEPRO100 NICs and up to two Syskonnect SK9843 NICs, Intel PRO1000/XT NICs and Broadcom BCM5701 NICs. It is already known that the Ethernet trunking does not work with some mixture of different NIC cards, e.g., the combination of the tulip and 3C05B NICs.

  6. PVM is not fully tested.

Known Bugs

  1. PM/myrinet2xp

    The pmWrite() function does not work with Myrinet2XP.

  2. PVM does not work in an SMP cluster.
