[mpich-discuss] how to work with server computers

Hi,
 You will have to read the EULA (End user license agreement) to know exactly how many processors is supported by your edition of Windows OS (For example a server and client version of the same OS supports different number of processors).
 You can find EULA for different versions of Windows OS at http://www.microsoft.com/About/Legal/EN/US/IntellectualProperty/UseTerms/Default.aspx .
 AFAIK, Ubuntu server and desktop editions differ in the default kernel configuration and the set of packages installed. You could (one may argue why) install packages on a desktop on a server and vice versa. There is no limitations on the number of processors supported by these editions (This link might be helpful - https://help.ubuntu.com/8.04/serverguide/C/preparing-to-install.html).

Regards,
Jayesh

Hi all 
I want to buy a HP Proliant DL380 G7 for running my codes I wrote c++ codes that use MPI library for parallel processing and I executed them on a PC with core i7 cpu and I got correct answer that I expected but the speed is low and I have to buy a system like hp proliant series and up to now I never used any system like this so I have some questions : 
what kind of operating systems I can install on it ?(windows 7,ubuntu desktop edition or ubuntu server edition ...) 
If I can install a desktop edition operating system on it will the operating system uses all the processors? 
thanks.
