Charm++ parallel programming system

[pellegrini <pellegrini AT ill.fr>]

Hi Abhinav,

thank you very much for your quick answer. OK, I will rebuild charm++ 
without ibverbs flag but if I understand
well I will not have infiniband  support anymore on the resulting build. 
Am I right ?

best regards

Eric
