[Wrf-users] machine to run WRF

Tue Jan 14 12:26:22 MST 2014

As Abdullah KAHRAMAN says its depend of what you need but in general
aspects the number and speed of the cores is very important overall in
resolution times, in this link: http://bit.ly/1dtl76F you found a simple
benchmark made for me for a i5 core pc with 8GB of RAM and 500 GB in HDD,
is in spanish but in Chile read spanish.

Se ya later!
