worked well in my case. I was able to compile. And run tiny1 all of it. And 
tiny2 in standard after.

I'm moving on onto small1.

Also I've compiled libgrid (on a compute node) and successfully integrated 
into CP2K. Is there a "benchmark" to see the effect, I mean a file in the 
tests-folder where people get difference without and with libgrid ?
I run H2O-512.inp, but not noticeable difference. I run a test I had (QM/MM 
with hybrid functional) and I didn't see noticeable effect (on short 
tests), and in the readme it said about "Gaussian to Plane wave 
transformations", so I assume a speed up in some routine in GPW (or even 
GAPW no ?)
Also, Iain said 
(https://groups.google.com/forum/#!searchin/cp2k/libgrid/cp2k/DU3KNkwM4as/8_bO8zjWZ0sJ) 
and here again, it's performance-critical.

So if I have a "working" benchmark, I can see if I miscompiled it (no error 
in the out of the libgrid compilation), or maybe wrong compiler option and 
subroutines affected:  integrate_v_rspace for example  ?

Regards, 

Rolf
