Re: [Gems-users] High Router power

[Niket Agarwal <niketa@xxxxxxxxxxxxx>]

Hi Shoaib,

	Please also initialize the E_in_buf, E_xbar, etc variables in line  
no. 352 of NetworkPower.C? These couple of errors have got in to the  
release. Correcting this should solve your problem.
Our group is working on the release of Orion 2.0 which has further  
corrections to the original Orion distribution. We will also plug it  
into GEMS soon.
Cheers,
Niket
