Several of the questions I asked before in my message "Quad-core Parallelism" have been answered at the site<BR>

My main question had to do with whether Duo-core or Quad-core CPUs can be addressed individually in a Beowulf system. Apparently they can as in the microWulf example. Thanks for several replies regarding options in using MPI type software. I note in reading over the microWulf text that they report only the LINPAK application. I am mainly interested in microWulf to set up GAMESS as available from Ames National Laboratory. Has anyone on this Forum set up an application on a microWulf system and in particular has anyone set up GAMESS on a microWulf system? Several other questions arise.<BR>
<BR>
1. It appears that the microWulf system could be extended to 16 CPU using quad chips. Would it be simpler to use just two of the faster Intel Core-2 Quad chips to achieve an 8-node system? Maybe it is much cheaper to use the older technology in the AMD 64-2X chips.<BR>
<BR>
2. Has anyone here used a microWulf for an actual application beyond just testing LINPAK?<BR>
<BR>
3. The microWulf system uses Ubuntu LINUX which brings up the question as to whether LINSPIRE could be used. I have both Ubuntu and LINSPIRE software but I like the near-Windows form of LINSPIRE. <BR>
<BR>
My questions may be more sensible if it is understood that I want an inexpensive parallel system to run GAMESS. Prof. Adams claims he was flooded with e-mail early in 2007 when the microWulf articles appeared and he may/may not have time to answer my questions so it would be of interest to me to hear from someone else who has built or is building a microWulf system.<BR>
