Dear all,
 I am trying to do some GW calculations with abinit 4.4.3.
I tried lesson #6 in the tutorial section, especially I focus on the 
case with
t69.in as the input file. I run abinis as well as abinip using 4 nodes.
Both calculations give the correct results, however, I don't see any 
speed up of
the parallel version.
The end of the output from abinip reads:
================================================================================-
- Proc.   0 individual time (sec): cpu=        948.6  wall=        995.3

================================================================================
Calculation completed.
Delivered   11 WARNINGs and   2 COMMENTs to log file.
+Overall time at end (sec) : cpu=       3880.2  wall=       3980.3

And the end of the output from abinis reads:
================================================================================
Calculation completed.
Delivered    9 WARNINGs and   2 COMMENTs to log file.
+Overall time at end (sec) : cpu=        971.7  wall=        991.7

So what is the problem?
Is the test too small to see the parallel efficiency?
How about the parallel implementation of GW in abinit up to now?
By the way, I want to know how large abinit can deal with
using GW method. Are there some references reporting the GW calculations 
using abinit?
Thanks.

Best wishes,
