Hi,
We would like to buy a new machine which would run RHL 7.1 It would be primarily used for number crunching (eg. Fortran) programs. Could someone help me with the following issues:
1. Processor: Does it really make a difference in Linux performance if the processor is an AMD or Intel ? Also, what speed would you suggest ?
2. What are the best HDD available today ? IDE /SCSI and how much capacity ?
I know this is a very open-ended question, but I would really appreciate your help.

Thanks in advance,
Anoop

i have RedHat 7.1 (upgraded from 7.0) on an AMD Athlon 850MHz machine and it runs great! i have a 30G Maxtor hdd and 384M Ram (corsair). i do a lot of my Java programming on this machine. i was playing around a couple weeks ago and wrote a Java program to calculate the factorial of numbers that i input... i ran the factorial of 2000 and it turned out to be 5 screens long! my RedHat system ran the calculation in a split second without a problem. i did not try it on windows.
that machine has win98, win2000 and RedHat 7.1 on three seperate partitions. the win2000 installation is giving me some problems, but win98 and Linux run great. i am about to upgrade to a 1.3GHz AMD processor, though, because my old processor has been overheating... actually, that is just my excuse to get a faster CPU.
i also have RedHat 7.0 on my Sony Vaio laptop... PII, 366Mhz, 2G partition. this runs well, too, but the boot takes a lot of my battery life, so i just run it when i can plug-in. if i do run Linux on battery, i just run in text mode.
oh yea, i do not know which hdd is better... i have IDE. you can run Linux on a very basic machine, but i suggest getting something pretty fast (750 or better) since a good processor does not cost that much right now.

If you use the box for number crunching pruposes, that means you won't use I/O that much, so IDE should work fine. Since the price of a 5600 rpm drive is not much cheaper that a 7200 prm harddrive, I would suggest 7200 rpm ATA/100 hard drive, IBM has probably the best hard drive around.
Linux works fine on AMD system. Depends on your budget, you might want to consider a dual AMD box, since the price for AMD is much cheaper that Intel counterpart.
Also, since you want number crunching, stability is the priority,
you should consider RAID setup, and other factors.
Hope this helps.
