Dear Lin-Woo, Yes, crystallography programs can be made to work on Linux systems with Dual Core CPUs. We run CentOS on Dell Precision 690 workstations and everything works well. We are using Nvidia graphics cards (specifically Quadro FX3450) and they work very well also. Nvidia Quodro graphics cards are PCI-Express compatible. I recommend that if you are considering to purchase Dell computers, see what their packages are like; usually they already come with an existing graphics card and I think that almost all cards you can buy today are more than sufficient for use with crystallographic programs. Buying the cards separately is frequently not such a good idea because the individual cards are quite expensive. Please note that you cannot necessarily use multiple processors for one and the same job. If you have a good compiler (for example, we have good experience with the Intel Fortran compiler), you can make your code much faster (compared to native Linux Fortran compilers) and it is possible to do some parallel processing to some extent, for example in the case of CNS. This takes extra effort though.
Hope this helps.

I try to build a new linux crystallography pc with most updated CPU. Is there anyone using Core 2 Duo CPU on your linux system? Is it working? ? (I will use NuVision stereo system with a stereo ready graphic card. Most of graphic cards use PCI-Express slot. I wonder after I buy the newest machine and it does not work with linux or crystallography programs.)? ? Please let me know? Thanks in advance. -- Sincerely yours, Lin-Woo Kang, Ph.D. Assistant professor Konkuk university Dept. of advanced technology fusion Tel) 82-2-450-4090 E-mail) [EMAIL PROTECTED] ________________________________________________________________________ Check Out the new free AIM(R) Mail -- Unlimited storage and industry-leading spam and email virus protection.
