i am working on graphene-lipid system for coarse grain MD and I have encountered a strange problem (might be i don't understand it correctly). i need your suggestions to understand what is causing warning.
During MD, when I run a system on CUDA based GPU (+p32; 4 GPU) system I encounter following error:
Warning: Low global CUDA exclusion count! (6547 vs 6552) System unstable or pairlistdist or cutoff too small.
i understand it is due to the reasons explained here http://www.ks.uiuc.edu/Research/namd/mailing_list/namd-l.2013-2014/3253.html, http://www.ks.uiuc.edu/Research/namd/mailing_list/namd-l.2009-2010/2786.html
and here http://www.ks.uiuc.edu/Research/namd/mailing_list/namd-l.2010-2011/3814.html
Although, when I run this same system on my linux PC I don't observe this error (+p8 1 GPU) and MD runs smoothly without any error or warning.
Can any one please explain what I am missing here or what is potential problem I need to fix.
Thanks in advance
