cp2k on BlueGene/P

Hi,
I found some problems running the version psmp on BG/P in JUGENE.

The job (256mpi_taskX4thread) crashes after the initialization, just before 
the SCF OT calculation, with following error:
cp2k.psmp: 
/bghome/bgbuild/V1R4M2_200_2010-100508P/ppc/bgp/comm/build/dcmf/include/devices/bgp/dma/DMAManyToMany.h:296: 
int DCMF::DMA::DMAManyToMany<TDesc>::Recv::processPacket(int, int, const 
char*, int) [with TDesc = DMA_MemoryFifoDescriptor]: Assertion `to_copy >= 
0' failed.
<Jun 13 12:06:45.749095> BE_MPI (ERROR): The error message in the job 
record is as follows:
<Jun 13 12:06:45.749214> BE_MPI (ERROR):   "killed with signal 15"
 
For the compilation I followed the advice of published PRACE  Million Atom 
KS-DFT with CP2K<http://www.google.com/url?sa=t&rct=j&q=cp2k%20on%20jugene&source=web&cd=1&ved=0CE8QFjAA&url=http%3A%2F%2Fwww.training.prace-ri.eu%2Fuploads%2Ftx_pracetmo%2FCP2K.pdf&ei=SDHgT-6AE-nP4QTz5LHADQ&usg=AFQjCNEiMhfPmxXZZkUthV5MIPqpdMY1yw&sig2=-X3ptOVkJxPf7yuFCCnNrQ>
 of Iain Bethune et al.
The only exception is the lack of library get_memory.o, because this is not 
in standard cp2k release and I have no idea how to make it.
So maybe this is the problem, but I would need help to code get_memory.

Another strange behavior is in the beginning of the output at the System 
Memory Details cp2k finds all zeros:
 MEMORY| system memory details [Kb]
 MEMORY|                        rank 0           min           max       
average
 MEMORY| MemTotal                    0             0             0         
    0
 MEMORY| MemFree                     0             0             0         
    0
 MEMORY| Buffers                     0             0             0         
    0

    0

    0
 MEMORY| SReclaimable                0             0             0         
    0
 MEMORY| MemLikelyFree               0             0             0         
    0

But it happens for popt version also and in this case the job runs until 
the regular end.

Have someone experience in compiling and running cp2k on BG/P?
How can I properly do it and possibly increase the scalability of cp2k?

Thank a lot in advantage,
 Daniele
