Building Qbox on BlueGene/P

[fgygi]

This post describes the steps used to build Qbox on the Argonne National Laboratory BlueGene/P computer (Intrepid).
The following assumptions are made:
- the bash shell is used
- the BLAS, FFTW2, LAPACK, SCALAPACK libraries are available in /soft/apps/libraries/xl

1) Building the Xerces-C library
Choose a directory to build the library. In the following, we build the library in $HOME/software/xerces.

Code: Select all

$ mkdir -p $HOME/software/xerces
$ cd $HOME/software/xerces

Get a copy of the Xerces-C 2.8.0 library from apache.org:

Code: Select all

$ wget http://www.apache.org/dist/xerces/c/2/sources/xerces-c-src_2_8_0.tar.gz

Untar the Xerces-C source tar file

Code: Select all

$ tar zxf xerces-c-src_2_8_0.tar.gz

Go to the xerces-c-src_2_8_0 directory and define the XERCESCROOT environment variable to be that location

Code: Select all

$ cd xerces-c-src_2_8_0
$ export XERCESCROOT=$PWD

Go to the src/xercesc directory, run the runConfigure script and make

Code: Select all

$ cd src/xercesc
$ ./runConfigure -p linux -c bgxlc -x bgxlC -n fileonly -r none -s
$ make

The library is now available in $HOME/software/xerces/xerces-c-src_2_8_0/lib/libxerces-c.a.

2) Building Qbox
Get the Qbox distribution tar file and the bgp-omp.mk makefile in $HOME/qb/

Code: Select all

$ mkdir $HOME/qb
$ cd $HOME/qb
$ wget http://fpmd.ucdavis.edu/software/qbox/qbox-1.56.2.tgz
$ tar zxf qbox-1.56.2.tgz
$ cd src
$ wget http://eslab.ucdavis.edu/software/qbox/makefiles/bgp-omp.mk

Define the TARGET environment variable as bgp-omp (note: do not include ".mk" in the TARGET string) and build

Code: Select all

$ export TARGET=bgp-omp
$ make

The Qbox executable is $HOME/qb/qbox-1.56.2/src/qb.
