Re: [PyMOL] Pymol on MacMini: performances
Thanks Sabuj, I thought so, but couldn't be sure, as a lot depends on the quality of the drivers... w/o Direct Rendering (ATI drivers sucks!), my ath64 laptop with R9700 only manages to give me some 4 fps... that makes it all but unusable. so i was afraid to find myself in an even worst situation... Hopefully, PyMol takes advantage of Altivec... I'll give it a try. thanks again... luca Sabuj Pattanayek wrote: Hi, I can run pymol smoothly on my celeron-m 1.3ghz laptop with intel i855gmch embedded graphics chip.

Hi Luca, I'm using MacPymol on an old blue and white G3, and it works fine. Einat To reply, please change the mmm in the reply-to address to hotmail _ Express yourself instantly with MSN Messenger! Download today it's FREE! http://messenger.msn.click-url.com/go/onm00200471ave/direct/01/
RE: [PyMOL] Pymol on MacMini: performances
Luca, We bought a Mini here in the office to use as an inexpensive, secure, stable, hassle-free CVS server. I hadn't tried running PyMOL on it until today... In a very small set of tests with surfaces, a $600 1.42 Ghz G4 Mini (ATI) has about 25% of the OpenGL performace and 60% of the ray-tracing performance of a $1800 1.8 Ghz iMac G5 (nVidia). For comparison, a $450 eMachines 2.8 Ghz Celeron (Intel Graphics) has about 80% of the OpenGL performace and 40% of the ray-tracing performance of the iMac. In other words, the Mini's CPU performance is great; the graphics performance isn't. However, if you just stick to displaying lines, then the Mini does very well -- as good as the iMac. You can display transparent surfaces of active sites just fine, but complete protein surfaces will seem rather slow. 512 MB RAM is a minimum recommendation for ray-tracing with PyMOL. 784MB or 1GB is better.

Apple has always had good graphics drivers, I wouldn't worry about that. My iBook (whose hardware is very similar to the mini) has much better PyMol performance than some of my Linux boxes whose hardware (both CPU and graphics) is more powerful in theory. However, nothing beats real-life experience. Pack PyMOL and your data on a CD and go visit your nearest Apple vendor!
