math/atlas-3.6.0,1 fails during install ("unable to get timings in
tolerance") and I noticed that the FreeBSD port for ATLAS does not
detect my second CPU even though the original ATLAS program does detect
both my CPUs. The latest fix to the port on March 30 at least allows
configuration to complete.
############ original ATLAS program
ATLAS can provide SMP support for the Level 3 BLAS via Posix
threads.
If you choose to build a threaded library, ATLAS will
compile all
aspects of the library (including the serial components)
with the
threaded compiler/link flags. Most machines can use the serial
library even when it is compiled with threaded options, but this
is not guaranteed to work, so if you want a true serial library,
answer no to threading below.
enable Posix threads support? [y]:
Number of CPUs: 2
