Hello,

Your actual number of elements per core, nelt, is greater than the 
upper bound, lelt -- to be precise,  nelt=14179 > lelt=288.

You should either recompile the case with larger lelt or increase number 
of cores your are running on (make sure you have appropriate upper bound 
for them, lp, in SIZE)

Best,
Aleks
