Hi,
I'm looking at trying to give MPI performance a boost with one of the
kernel-assisted memory copy modules. I see there are a few of them,
including LiMIC2 and KNEM.
The website for LiMIC2, http://sslab.konkuk.ac.kr/, isn't responding but
MVAPICH2 seems to be the biggest user of the software (according to
Google), so I'm posting my question here.
I've read about a few security concerns about LiMIC2 dotted around the
net, but not found any official documentation to confirm/refute that an
attacker can use it to read any memory they like.
Are the concerns real? If so:
* Are there any plans to address them?
* Is KNEM supported with MVAPICH2 as an alternative? (I see it wasn't in
2011)
Thanks,
Mark
