run apps like seti@home classic from mem card?

[Wiz]

I can't think why this wouldn't work or be an ok thing to do - running a dc app from a memory card? I have a portable USB2 card reader & some mem cards - why not run seti or F@H or whatever from where ever I sit down?
Thoughts? Ideas?

There's no reason why you can't.

I'm going to load seti1 & Seti Driver on a 64meg SD card tonight then try it tomorrow.
Should be interesting if nothing else.
With the multi card reader plugged in each slot shows up in Win XP as a "Drive".

As long as it has a means of connecting to the net (or of course if you're going to sneaker it, as long as it has a way to process), you'll be fine. AFAIK, you can run S@H on just about anything

 

[petrusbroder]

Hmm, I do that every day. I do not have administrator's rights om my work computer, and according to the agreement I may not install any programs on the hard disk, but there is no prohibition at all of connecting a USB2-dongle to the comp, as a matter of fact I was provided with one 512 MByte unit by my employer to move sensitive documents in a safe way (encrypted...) from my office to work at home. Works with setdriver perfectly ... I set the driver to "transmit manually" since all traffic to the 'net is checked and so on. I checked with the system administrator and he gave me OK - he runs Seti too from a SD-memory card....

Very Cool

I'm just on a 2ghz celeron right now, but they are buying me a 3.8ghz P4 with all the bells & whistles...

 

[networkman]

Yep, as long as the client is pretty much "self-contained", there's no problem with using a USB drive to run your app. I've also done it with S@H on a USB drive - no issues.

Nice upgrade coming

I briefly run my 'mobile' SETIQ from my flash drive every Friday to flush the work Q

I'm waiting to compare a 4600+ to a 4800+ to see how much the L2 cache makes a difference. At this point, I'm hoping it does (I honestly don't recall if it does or doesn't impact WU times). The 4600+ is here, just waiting for the 4800+ to arrive to build a box out of it.

 

[GLeeM]

Yep, Seti Driver works great for doing this! Will miss that ability when Classic ends

I've run F@H from a USB thumb drive too. Only it needs to have a user ID in the registry which it can get from Stanford server. If no net connection, and I have user level permission to write to registry I merge the info in the key that I export from home computer registry. No problem.

Yes it does impact WU times ,it used to have a big effect but how much difference it'll make to an awesome CPU like the 4600 I don't know.

Wow, P4 Celerons really suck!

My P3 1.26 flies compared to a 2ghz P4 Celeron!!

It's done a couple WU's now & seems to do them in 5 1/2 hours.
My P3 1.26 does them in 3 1/2 - 4 1/2 hours depending on AR.

Guess it's the small cache & low fsb. Can't wait till they replace that thing with a P4 3.8

BTW - running seti off an old 64meg MMC card.

The Celeron D's are much better. More cache... just seem faster in general.

Hmmm My celery chip did better then that. I think you got something messed up. You arn't loading work units on that mem card are you? That would be the reason since it's SLOW. If you have fast ram a celeron should do about 6-7 WU per day.

Good Luck.

 

[petrusbroder]

I am not so sure that a slow memory card really matters - as long as you have enough RAM in the comp. The reading and writing to the card takes only a part of a second and does not happen that often - lets say once a minute or so. That would make some 300 times in 5 hours - probably much less than 30 seconds totally in that time ...

I have compared the effect of a really slow HD (a 2 GByte unit with 128 kb cache) with an RAM-disk (for the WU) and the difference was less than 2 minutes in a system with a old 800 Mhz Celeron. Of course, the swap file was on the boot disk - which was faster, and I had 512 MB RAM ... That difference is not significant because the WUs may differ much more.

I have compared running seti classic from my usual comp - with a scsi system - with running it from a 512 Mb USB2- flash-unit: less than 3% difference! - and that may be attributed to the difference in the WUs or the use of the comp during the test period ... (I crunched 20 WUs one way and 20 WUs the other way and compared the total crunching time)

 

[Wiz]

I think you are correct, that also seems to be my experience with seti1.
Writes to the disk are about once a minute and small, except at the conclusion of the unit / beginning of the next unit.
However selecting to not transmit automatically reduces that too.

No ,that will barely effect WU time.
Was your Celeron the latter 'D' type ? or maybe the older PIII based Celeron?

I was asking MicroChrome but interesting anyway

Can't you cut the RAM latency down? ,that won't be helping.......oh wait it was a work PC right? nm

 

[Wolfsraider]

A recent compaq 2.8 celeron I had in for cleaning only would do 3-4 wu a day. but it was using pc 2100 ram. just fyi.

It's a Dell - doesn't seem to have much in the way of adjustability in the bios

LOL, yea, pretty worthless BIOS.
