In order to enable valgrind support:
|
|
1) download and build (into the same dir for convenience) two libraries: libmlx4 and libibverbs with valgrind support.
|
|
- http://www.openfabrics.org/downloads/libmlx4/
|
|
- ./configure --prefix=/PATH_TO_LIBS --with-valgrind && make && make install
|
|
- http://www.openfabrics.org/downloads/libibverbs/
|
|
- ./configure --prefix=/PATH_TO_LIBS --with-valgrind && make && make install
|
|
|
|
NOTE: libmlx4 and libibvers should match your ofed version
|
|
|
|
2) build shmem with valgrind, memchecker module and these two libs:
|
|
./autogen.sh && ./configure --prefix=$PWD/install --with-openib=/usr --with-oshmem --with-openib-libdir=PATH_TO_LIBS --with-valgrind=PATH_TO_VALGRIND --enable-memchecker --disable-dlopen && make clean && make && make install
|
|
|
|
- --with-openib=/usr - the place where to look for infiniband
|
|
- --with-openib-libdir=PATH_TO_LIBS - two libs previously installed
|
|
- --with-valgrind - the --prefix to the valgrind install. that must contain $prefix/include/valgrind/valgrind.h and $prefix/valgrind/memchecker.h. Should be /usr if valgrind installed from rpm

In order to get rid of them use an extra command line option to valgrind: --suppression=${prefix}/share/openshmem/openmpi-valgrind.supp --suppressions=shmem_suppressions, where shmem_suppressions is the file in the root of the shmem code and ${prefix} is shmem install prefix as set by configure.
