A build of 1.8.4 with just "./configure --prefix=..." produces the following VT libraries with reasonable sizes which are similar to previous releases (the largest one is 1.5 MB):
$ cd /home/devel/mpi/openmpi/1.8.4/lib/ && ls -lh *.a -rw-r--r--. 1 dalcinl users 531K May 8 13:42 libopen-trace-format.a -rw-r--r--. 1 dalcinl users 44K May 8 13:42 libotfaux.a -rw-r--r--. 1 dalcinl users 664K May 8 13:42 libvt.a -rw-r--r--. 1 dalcinl users 1.1M May 8 13:42 libvt-hyb.a -rw-r--r--. 1 dalcinl users 970K May 8 13:42 libvt-mpi.a -rw-r--r--. 1 dalcinl users 1.5M May 8 13:42 libvt-mpi-unify.a -rw-r--r--. 1 dalcinl users 655K May 8 13:42 libvt-mt.a -rw-r--r--. 1 dalcinl users 65K May 8 13:42 libvt-pomp.a After cheking the build directory, I confirm VT seems to be being built with optimization and no debug symbols: $ grep CFLAGS /home/dalcinl/Devel/BUILD/openmpi-1.8.4/ompi/contrib/vt/vt/Makefile CFLAGS = -O3 -DNDEBUG -finline-functions -fno-strict-aliasing -pthread CFLAGS_FOR_BUILD = -O3 -DNDEBUG -finline-functions -fno-strict-aliasing -pthread However, after building 1.8.5 exactly the same way (i.e, just ./configure --prefix=...), VT libraries have much larger sizes (the largest one is now 16 MB, i.e. 10 times larger): $ cd /home/devel/mpi/openmpi/1.8.5/lib/ && ls -lh *.a -rw-r--r--. 1 dalcinl users 1.7M May 8 13:42 libopen-trace-format.a -rw-r--r--. 1 dalcinl users 181K May 8 13:42 libotfaux.a -rw-r--r--. 1 dalcinl users 1.9M May 8 13:43 libvt.a -rw-r--r--. 1 dalcinl users 2.9M May 8 13:43 libvt-hyb.a -rw-r--r--. 1 dalcinl users 2.8M May 8 13:43 libvt-mpi.a -rw-r--r--. 1 dalcinl users 16M May 8 13:43 libvt-mpi-unify.a -rw-r--r--. 1 dalcinl users 1.9M May 8 13:43 libvt-mt.a -rw-r--r--. 1 dalcinl users 175K May 8 13:43 libvt-pomp.a and after inspecting CFLAGS in the build directory I get: $ grep CFLAGS /home/dalcinl/Devel/BUILD/openmpi-1.8.5/ompi/contrib/vt/vt/Makefile CFLAGS = -g -O2 CFLAGS_FOR_BUILD = -g -O2 However, plase take a look at the Makefile in one directory up: $ grep CFLAGS /home/dalcinl/Devel/BUILD/openmpi-1.8.5/ompi/contrib/vt/Makefile CFLAGS = -O3 -DNDEBUG -finline-functions -fno-strict-aliasing -pthread CFLAGS_WITHOUT_OPTFLAGS = -DNDEBUG -fno-strict-aliasing -pthread So it seems that in 1.8.5 CFLAGS is not being propagated from ompi/contrib/vt to ompi/contrib/vt/vt Given that the Makefile ompi/contrib/vt looks ok, but the all the others in subdirs under ompi/contrib/vt are not, this smells as a build regression your are likely not aware of. -- Lisandro Dalcin ============ Research Scientist Computer, Electrical and Mathematical Sciences & Engineering (CEMSE) Numerical Porous Media Center (NumPor) King Abdullah University of Science and Technology (KAUST) http://numpor.kaust.edu.sa/ 4700 King Abdullah University of Science and Technology al-Khawarizmi Bldg (Bldg 1), Office # 4332 Thuwal 23955-6900, Kingdom of Saudi Arabia http://www.kaust.edu.sa Office Phone: +966 12 808-0459
