RIM. Problems with

[amolina]

Hi everyone,

this is my first post in this forum, and I would like to thank the developers for the nice work they are doing with Yambo.

Well, after having used YAMBO for several materials and for several machines, I got a problem. When I am using the option RIM, the program stop at the following step:

[07] Bare local and non-local Exchange-Correlation
==================================================
[EXS] Plane waves : 3281
QP @ K 061 - 061 : b 005 - 015
[FFT-HF/Rho] Mesh size: 18 18 54
[ERROR] STOP signal received while in :[07] Bare local and non-local Exchange-Correlation
[ERROR][NetCDF] Variable not found

I find this problem only when I am working in Tirant, IBM computer. If I am working in other machines, like AIX, the same input finish without problem.
Is that an installation problem? What can I tell to the admins about that? we have already installed the last version and we still get the same...

Cheers,

Alejandro.

Dear Alejandro,
I'm not sure that your problem is related with the RIM,
but with the netcdf library, and usually appears when working
with very big databases (is this your case?). If this the case you can solve it
using the -S flag when generating your databases (with p2y or a2y). This flag
fragment your databases, avoiding to have too big files.
Please have a look at this post.
If this is not the case, we will need to investigate more deeply the reason of the failure.

Hope it helps,

Cheers,

Daniele

Dear Daniele,

thanks for your help. Adding -S to the a2y executable makes the program work. It was a fragmentation problem. Maybe the IBM is configured in such a way that needs this fragmentation.
Cheers,

Alejandro.
