Hi, While I've seen a number of examples of good graphics cards to use with Pymol, I'd like some feedback on what an acceptable low-end is for a Windows laptop computer. Specifically, is the Intel GMA950 completely useless or just not very good. Likewise, does the X3100 help (this seems to be weak on driver support)? =20 =20 My current system uses an ATI Mobility Radeon 9200, which is a few years old and not a high-end gaming/workstation card, but lets me spin a molecular cartoon or surface of a ~300 residue protein without any problems (if the 950 or X3100 equal this level, I'll be satisfied). Many of the current crop of <5 lb notebooks use integrated graphics for price and battery life. If these units don't provide sufficient graphics power for Pymol/VMD/Deepview, the useful market shrinks substantially. =20 Thanks, David =20 =20 -----------------------------=20 David A.

I use Linux (Debian) only on this laptop and with the fglrx ATI driver it certainly gives acceptable performance. I can spin a 300-residue protein drawn in surface mode easily enough. It seems to be only a little slower than my desktop, which has a ATI 9500 Pro. I don't recall trying it on this laptop before I blew Windows off the disk, but I'd expect you'd get at least as good performance with Windows as Linux. The Thinkpads are nice small laptops.

Dear Colleagues, We are pleased to announce a new mini-beam capability at the two GM/CA-CAT undulator beamlines in Sector 23 of the APS. We have implemented an apparatus to produce a strong, stable X-ray mini-beam. The apparatus is rapidly interchangeable with our standard beam. The flux and stability of the mini-beam have allowed successful data collection from macromolecule crystals of 5-10 micron size. We have tested the apparatus on several challenging projects with excellent results. Properties of the mini-beam are listed below. Size: user choice of 5 microns or 10 microns Flux: 1-2x10^13 photons/sec Flux stability: < 1% RMS over one minute; < 3% drift over 12 hours Beam time applications for the 5-10 micron mini-beam on GM/CA beamlines 23-ID-B and 23-ID-D can be made through the APS proposal system at http://www.aps.anl.gov/Users/Become_A_User/Getting_Started/index.html=20 or by contacting Sheila Trznadel at str...@an... or +1-630-252-0662.

Dear Colleagues, Correct flux in our mini-beam announcement (see below) should have been 1-2x1011. Originally quoted flux is that of a full beam. We apologize for the confusion.

David, As long as you run Windows XP and not Vista, most modern "shared-memory" GPU systems should have sufficient performance for PyMOL. If you're thinking of new systems, it is no secret that I unabashedly favor and recommend the Windows-&-Linux-capable PC laptops made by that consumer-products company based out of Cupertino. The GMA950 is a fine mid-range solution -- but be sure to upgrade to 2 GB of RAM so that you can dedicate 1G to virtualized operating system instances. Cheers, Warren _____ From: pym...@li...
