I'll try :-)

I have only tried with pathscale (my top priority right now is to get
the VASP code running so i'll stick to pathscale a while longer).
The number of nodes vary from 8 to 25 (we have dual quad-core nodes so
x8 for processors). The system is an IBM blade system with Mellanox
Technologies MT25208 InfiniHost III Ex adapters.

configure --enable-error-checking=all --enable-error-messages=all
--enable-g=handle,dbg,mutex,meminit --enable-fast=none,O0
--with-rdma=gen2 --with-pm=mpd --without-mpe

(with CC and so on set to pathcc etc)

Running without any mvapich env vars set.

As for the inputs to VASP i don't know enough about VASP to be able to
guess why some generate the error and some not.

Note also that mvapich2 1.0.2p1 gave the same assertion error when i
used it.

If you need more details just ask.
