If you saw Mellanox's commit this morning, you noticed a comment about how the
glibc malloc hooks are deprecated. I pinged Mike D. about this off-list, and
he sent me the following reference from the glibc 2.14 release notes at
http://sourceware.org/ml/libc-alpha/2011-05/msg00103.html:
* The malloc hook implementation is marked deprecated and will be removed
from the default implementation in the next version. The design never
worked ever since the introduction of threads. Even programs which do
not create threads themselves can use multiple threads created internally.
Yoinks.
The OpenFabrics community had better come up with something to replace the
glibc malloc hooks implementation fairly soon... (e.g., push ummunotify
upstream, or push something else -- Mellanox is currently arguing that On
Demand Paging will obviate the need for something like ummunotify; see the
linux-rdma mailing list for an ongoing discussion about this exact topic)
