The ABINIT Users Mailing List ( CLOSED )

[Sun Hong <hsun@sjtu.edu.cn>]

Hi, 

         Abinit is the main program in our group. Recently, 
an USD50,000 fund was granted to us to set up a small PC 
cluster. We consulted with both Intel and AMD companies 
here in Shanghai, China. They all suggested a PC cluster 
structure of 15 computing nodes (each with 2 CPUs on 1 
motherboard) + 1 server connected together by 16 Intel 
1000M ethernet cards. As we have no experiences, we would
be very grateful to you if the following questions could
be clarified before our purchasing:

    (1) Could abinit program be installed and run on the 
linux cluster where 2 CPUs on 1 motherboard share the same 
memory?

    (2) Which version of MPICH works best for this kind
of cluster and abinit?

    (3) Which CPU (Intel and AMD) works best for this
cluster and abinit?   
  
    Any other comments and suggestions are also greatly
appreciated. Thank you in advance for your kind help.

Best regards

Hong SUN
