Charm++ parallel programming system

[Ted Packwood <malice AT cray.com>]

Hello-

I'm trying to determine what is causing a failure in NAMD when built with
the Cray compiler on a Cray XC30.

The failure is in "setJcontext" as you can see from the traceback below.

The charm++ build works fine with the include charm++ test  "jacobi3d"
(4ranks on 4 seperate Broadwell chips, +ppn6)

I built charm++ with:
./build charm++ mpi-crayxc craycc smp

NAMD was built with:
./config CRAY-XC-cce --charm-arch mpi-crayxc.cce-smp-craycc --with-fftw3 --without-tcl --charm-opts -save

And was run with just one rank on a Broadwell chip.

The intel compiler build of charm++ and NAMD works fine, so this appears to
be an issue with the Cray compiler.

I have a few questions:
1) Does anyone have an idea of what might cause this type of failure?
2) Any suggestions as to a possible solution, or build changes that might
solve the problem?
3) Is there a simple charm++ test which mimics the Jcontext usage that
NAMD requires that might cause a similar failure?  I'd prefer to try to reproduce
this with a smaller test than NAMD.  :)
4) If not, should I contact the NAMD folks instead?
