blacs-test-common 1.1-31ubuntu1 (amd64 binary) in ubuntu precise

 The BLACS project is an ongoing investigation whose purpose is to
 create a linear algebra oriented message passing interface that may be
 implemented efficiently and uniformly across a large range of
 distributed memory platforms.
 .
 You can choose between an implementation based on MPI or PVM. This package
 provides test data for all BLACS packages (MPI and PVM versions).
 .
 Most users do not need to install this package directly because it is
 installed when installing the test programs for any BLACS package.
