Dear charles and any others


I had a couple of questions to ask while finishing up my ensemble code

1. In an ensemble calculation how do i treat data that doesn't need to be 
shared but is ensemble member specific. I am especially thinking about the 
difference between a threaded simulation and a multi node simuation that 
communicates across a socket. So if i take a non bonded list as an example: in 
this case each ensemble member simulation will have to have a non bonded list. 
However for the threaded model i will need all three present in the same 
address space whereas for the muti processor version each address space will 
need to have only one (the one for its own member simulation). What s he best 
way to set up the non bonded list have an arrayof non bonded lists one for each 
ensemble member and then allocate them as data for ensemble members is 
requested?

2. When do shared cds vectors get syncronised is it at each syncronisation  
barrier?

Regards gary

Nb i have seem to ahve ironed out all the installation problems for the single 
threaded version with the help of alvin, would you like me to send the latest 
instructions on to you?
