Re: [Gems-users] failed assertion 'index < m_size'

[Hemayet Hossain <hossain@xxxxxxxxxxxxxxxx>]

Thanks for the sharp reply.
I did not change the configuration parameters (the default configuration 
file is attached). I tried with gems 1.2. That is not creating that 
problem. One difference I see in output is "Processors: 8" in gems 1.3 
whereas "Processors:16 " in gems1.2. How #processors= 8 is set?
Thanks.
