[Trilinos-Users] [EXTERNAL] Re: decomp tool Error

[Sai P Uppati]

UPDATE:

I think all other tools may be working fine from my trilinos build. The
tools I commonly use from trilinos include decomp, epu, exodiff and epu.
All except decomp seem to working fine.

Even after rebuilding trilinos several times (varying some options each
time) and Peridigm passing all the tests each time, decomp throws errors
like these:

Executing:
   /usr/local/trilinos/bin/nem_slice -e -S  -l inertial -c -o
HEGF-res-cylin.g.nem -m mesh=4 HEGF-res-cylin.g
   ...see HEGF-res-cylin.g.decomp.out for nem_slice status

Beginning nem_slice execution.
Input Mesh File = 'HEGF-res-cylin.g'
Using 32-bit integer mode for decomposition...
Exodus Library Warning/Error: [ex_put_cmap_params_cc]
Error: failed to add dimension for "ncnt_cmap" of size 6313656973 in file
ID 65536
NetCDF: Invalid dimension size

fatal: unable to output communication map parameters
