The BCCD, or Bootable Cluster CD, is a diskless cluster solution "created to facilitate instruction of parallel computing aspects and paradigms." More information about the BCCD can be obtained from bccd.cs.uni.edu, as well as from the BCCD's main wiki, which this page is meant to complement.

Building the BCCD on PowerPC

The instructions that formerly lived here have been replaced by the generic build instructions.

TODO List for BCCD/PowerPC

Fix Runtime Build Environment

1) /etc/ld.so.conf

change /lib/gcc-lib/i386-lnxbbc-linux to /lib/gcc-lib/powerpc-lnxbbc-linux

bccd/special/bbc-provided/files/ld.so.conf

2) LD_LIBRARY_PATH in /etc/bashrc

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib/gcc-lib/i386-lnxbbc-linux/ should be: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib/gcc-lib/powerpc-lnxbbc-linux/

bccd/special/bbc-provided/files/bashrc

3) Fix library install dir:

ld looks at "/tmp/${USER}.build/staging/singularity/image/lib" to find the libraries that are in "/lib":

/bin/../lib/gcc-lib/powerpc-lnxbbc-linux/3.2.3/../../../../powerpc-lnxbbc-linux/bin/ld: cannot find //tmp/gray.build/staging/singularity/image//lib/libc.so.6 collect2: ld returned 1 exit status

Not sure what needs to be changed here.. (the quick fix on the image is mkdir -p /tmp/gray.build/staging/singularity/image && ln -sf /lib /tmp/gray.build/staging/singularity/image/lib)

4) CPP defaults to /lib/cpp, but cpp is at /bin/cpp and /usr/bin/cpp

5) MPICC

export MPICC=/lam-mpi/bin/mpicc

so mpicc is found?

6) LDFLAGS - may be fixed once above issues are addressed

Maybe this will come automatically once LD_LIBRARY_PATH and/or ld.so.conf is fixed, but:

export LDFLAGS="-L/lib/gcc-lib/powerpc-lnxbbc-linux"

is currently necessary while building FFTW:

checking whether the Fortran 77 compiler (f77 ) works... no

configure: error: installation or configuration problem: Fortran 77 compiler cannot create executables.

(can't find -lfrtbegin)
