I second the recommendation for NOD32. Launch times were horrible with McAfee, with NOD32 the system is snappy.

> I don't remember ever using -forceasm. Is that necessary for a P4 processor?

In theory it is never necessary. What it does is force the use of the fast assembler routines even if the program has crashed and restarted.

>Two years ago we were all tweaking the command line with -advmethods >and such to try to get as many gromacs as possible. Hi, David. You still want -advmethods and -forceasm. In addition, you want to set the option for large workunits (by running with -config or -configonly and answering the questi...

Hi, Erssa. Here is a cautionary tale that may be relevant to this discussion. I thought I was pretty safe when I had a Promise SX-2000 controller in my office PC with a pair of mirrored disks. I could tolerate a disk failure with no impact whatsoever. But one day a power failure hit during a disk wr...

I disagree with the statement that Raid 0 has no beneficial effect in real-world usage scenarios. Raid 0 significantly improves my application launch times. For instance, launching firefox improved from 16 seconds to 9 seconds. (The launch time is dominated by the antivirus on-demand scanning: if I ...

... You just have to understand which science he's talking about.
Perhaps one of those branches of materials science that studies CRUSHING and ABLATION.

In my case it is 54 cpus. Most are pentium 3 at 700 or 800 MHz. The majority of them will be going out of service soon, because Stanford is now refusing to give out batches of timeless tinkers and gromacs, and with my version of Red Hat linux I require either tinkers or a full batch of 10 work units.

Thanks for the notice. I've posted over there to urge that they go back, because when a gromacs is sent to one of my machines that runs red hat linux v9, it runs to completion and then hangs, and it never gets any points, completely wasting a cpu.

My points rate more than doubled, from about 650-700 to about 1500. It's because most of the machines are "tinkers only", so they are getting much more credit now.

I'll have to console myself with the point total, because my standing in the team is going to drop drastically over the next couple months as the four horsemen go storming past.

I'll enjoy it for a little while until our real heavy folders stomp their way past. And it will become easier for them over time, because my creaky old pool of P3's is showing its age -- over the past month 3 dual-CPU machines have gone out of service from assorted hardware failures, and more are lo...

Probably today is the day. I just got past a burst of big tinkers, and now the cupboard is looking somewhat bare. My true daily average is somewhere around 700, and Lockheed's is substantially greater than that, so it's only a matter of time.

So true. With his massive output, Lockheed deserves to pass me and duke it out with TRC-13. I'm just thankful that mjrusso45 backed off so that I could visit 2nd place for a little while. And I didn't even have to pay him. (Ok, mj, time to get back to work.) It looks like I'll have a bunch of 70-poi...

I have a 4-disk RAID setup with all 4 in SmartDrive2000s.
The disks are quiet enough for me this way, and the SmartDrives
are always cool to the touch in my well-ventilated case (6 very
slow fans.)

The -advmethods flag does not request gromacs instead of tinker. -advmethods says you are willing to run beta code, even though it may fail and crash your machine and give you no points. Back when Gromacs was in beta test the -advmethods flag did get you gromacs work units, but that is not quite so ...

I got some of the silenx.com fans. They are quiet, undervolt well, have the tach signal on the 3rd wire, have a thermal sensor for speed control (on a 12 inch lead), and come with 4 of those isolation mounts to use in place of screws. There is (was?) a price discount for quantity 10. In my view, sil...

A Smart Drive holds 1 3.5" hard disk and fits into a 5.25" slot, so 2 disks will require 2 Smart Drive boxes.

The Smart Drive 2002 has cooling fins on 3 sides, so it looks like the better choice for keeping drives cool.

I'm using the Zalman MFC1 controller with the fans from silenx.com . These fans have thermal control, so at a 25 degree ambient they run slower at higher voltage. I run them at about 1050 rpm with no flicker from the MFC1 LEDs. (The LEDs flicker somewhere below 900 rpm on the silenx.com fans -- when...

I see that Zhentar should turn orange any time now, and TRC-13 is really ramping up his production lately. Makes me wish I weren't running on creaky old 800MHz boxes.

I've been running four 120GB WD and Maxtor 7200rpm drives in smartdrive 2002 enclosures for several months now with no problems. In particular, no signs of overheating. But they get good airflow: they are in the bottom front inside a Lian-Li PC-70 case, where they get washed by the intake fans. (Act...

Whenever RedHat releases their supported update from glibc v27 in Linux version 9, I should be able to about double my output. At present there's about a 50% chance for each workunit that it will run to completion and then be discarded without registering any points. This is a known problem that the...

How about a brief review of fan controllers? There are several out now; newegg lists 4+ channel controllers from Galaxy Technology and Vantec Nexus; there's the Sunbeam Rheobus, the Zahlman 6-channel controller.... There's also the 1-channel controllers like the FanMate. Do they produce much heat? D...

Is a quiet case such as the Sonata or Lian-Li PC-6070 enough to muffle the continuous
noise from 4 disks, or would I be better off with a conventional case and 4 SmartDrive 2000?
(Assume a SilenX power supply and good, properly undervolted fans in any case.)

Some of us run scientific computing workloads that saturate the CPU for long periods of time, and we prefer quiet computers too. Please don't omit the fully-loaded tests -- they provide information relevant to workloads that do occur in the real world, even if they aren't representative of typical p...

Perhaps someone who has a Lian-Li case (or who has looked closely at the inside of one) can answer this: Is it feasible to decouple the internal hard drive cage (holds 5 or 6 disks) from the case frame, perhaps by some highly-compliant isolating bushings? From photos at Newegg, it appears that in th...

I concur that running your ata133 drive on an ata100 motherboard will work and will give nearly the same performance. If you are handling large files (half-hour WAV files, large video files), then the improvement from ata100 to ata133 isn't enough anyway; you should look into 2-channel or 4-channel ...
