Hello
I have been using dmtcp on various systems and I have been able to get
at least one version to work on each of them.
However, I just got a new notebook and the 4.3 version that comes with
the current fedora 23 does not work at all on this notebook.
It is an asus zenbook ux305ca, Intel Core m3-6Y30, running the
64 bit 4.5.3 kernel as built by fedora 23. I need that new kernel
to get the touchpad to work. Everything is 64 bit.
dmtcp_launch segfaults at startup on anything I have tried.
I attach the beginning and end of a typical (very long,
apparently in a loop) gdb stacktrace, and an entire strace
that result from "dmtcp_launch python" (whether or not
a coordinator is started first. Same result if I give
the exact pathname of the binary).
It appears in the strace that it locates and then
successfully executes the python interpreter, and goes
on a while further before finally segfaulting.
I have also download and built v 4.4, v 4.2, and v 4.0 and
they segfault right away as well.
I sure hope it is known that, e.g., dmtcp currently
doesn't work with newish skylake processors or newish
4.5 kernels (or that I am doing some silly thing
wrong). Otherwise this new computer isn't losesa lot
of functionality!

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
