Hi,
I am a new user of ddscat.
I try to calculate scattering and absorption efficiencies of metal nanoparticles of arbitrary shapes and sizes.
I did a serial calculation with a sphere easily. but when I try a parallel calculation with MPI, I find very high values.
It is the same for all the algorithms
ZBCG2 IT= 1 f.err= NaN
…
cgcommon ckpt 20
iter= 8 frac.err= NaN
…
GPBICG IT= 10 f.err= 6.167E+00
…
…
sqrt(rnorm/bnorm)= 3 174106950333229.
sqrt(rnorm/bnorm)= 4 NaN
Other codes using MPI have been successfully implemented in our system, and the job submission procedures are correctly implemented.
The administrator followed all the instructions in the USer Guide. Did we miss an important information?
