Hi users,
I just wanted to report on an experience I just encountered with OpenMPI 2.0.1,
mxm, and jemalloc (stack trace at end).
The jemalloc allocator is a high performance concurrent allocator but it is not
reentrant. During an application-level free() (frame #40 below), jemalloc can
cascad
The slides will definitely be available afterwards. We'll see if we can make
some flavor of recording available as well.
