Subject: Another naive Beowulf question
Date: Fri, 30 Apr 1999 21:11:27 GMT
I have not looked at Beowulf in any detail yet, but:
Can computers enter and leave the cluster while processing is
occurring? I have some logic fault testing software that runs for days
at a time.I would like to dual boot some machines in the office, so
that when people leave for the day, they could reboot their machine
and "enter" the cluster, then "leave" the cluster (reboot to win98)
the next morning. This way I could make use of several additional 450
MHz Pentium machines during the off 14-16 hours of the day for
weekdays, plus 24 hours a day on weekends (or on a person's vacation
or sick days). The thought of reducing run times in this manner is
very attractive.

Subject: Promise EIDE 2300+ card work w/ Linux?
Date: Fri, 30 Apr 1999 17:07:53 -0400
Hi
I've worked with Linux before, but am new to its installation.
I'm wanting to install RedHat Linux v4.1 on a i486DX2-66 system. The
motherboard BIOS does not support EIDE only IDE (1 channel).
I have a Promise EIDE 2300+ Vesa LB controller card with onboard BIOS
that I'd like to use with my 1.6GB hard drive.
I could not find info on this card in the Linux Hardware Compatibility
HOWTO file.
Anyone experienced in using this card?
Will RedHat Linux work with this card in using its EIDE BIOS to
supercede the IDE BIOS on the motherboard? Do I need a particular
driver?
How about installing Linux using this card with its EIDE BIOS active
right from the start?
Thanks for all/any help.
Roger.

The only think I can add to the "it works fine" reports is that
whoever put this printer in the database suggested getting some extra
RAM ove rthe basic 2M. The printer holds up to 66M, apparently, and
takes regular 72pin SIMMs.
If anyone with such a printer has one on their parallel port and runs
Linux 2.2, could you please report me the contents of your
/proc/parport/0/autoprobe file?
For that matter, anyone with any printer at all under 2.2 should fill
in autoprobe info at http://www.picante.com/~gtaylor/pht/printer_list.cgi

Check out dpt.com and have a read thru the tech library
These guys can supply a dual channel RAID controller with professional
Linux drivers one PCI slot for all HDD occassions!
Hardware raid will make the I/O go about 20 times faster!
The RAID stack will appear as one logical device if you set it up that way!
Hope that helps!

I think we need a different newsgroup just to address the

"39 MESSAGES" in the past 2 days just addressing modems...
so do we have a problem here??
I gotta admit... I'm having lotsa problems installing my
modem too... rather making 5.2 recognise my internal modem...
i do know that the internal modem is on Comm3 with IRQ 11 .
Runs without problems when I boot Win98 ... so Im assuming
there are no IRQ issues. Its not a winmodem either.
Apologise for showing my frustrations like this.. but then
where else do I turn or help??

Near as I can tell, he runs `startx` and gets a blue screen and the machine
does nothing more, only the reset button revives it.

It's pretty much like any other printer that offers PCL (I think it's
5e for the 1100). You'll want to make sure your kernel has parallel
port support, and that the lpr (or perhaps lprng) packages are installed.
You will want to use magicfilter or apsfilter to handle the various
formats of files; and of course ghostscript. I dimly recall their
being some additional software to control resolution, etc., as in
the WinXX environments.
I'm not familiar with SuSE, so I can't be more specific. Surely this
must be in their documentation. You should become familiar with the
HOWTOs, which were probably installed into /usr/doc/HOWTO.
Have fun!

Subject: Re: removing cooling fans--how dangerous?
Date: Fri, 30 Apr 1999 19:53:08 -0400
Here's a few things that may help. First if your fans are behind sheet metal
with holes, that creates more noise. When I upgraded to a better front fan,
I had a mini jet engine sound. It also impedes the airflow. I just used
snips and cut out one large hole. I still get noise from the rear fan but
it's not bad.
Here's what else I did. About a month ago, I stopped hearing that power
supply fan in the rear. I took it apart and found the temp control
transistor was toast. I looked up the transistor and found it had a .9W
dissipation. My fan (original) is stamped 1.6W. Hmm? I connected it directly
to 12V but that lasted just a few days before my wife began to protest. It's
right next to the TV. What I did was rig a circuit that did the same thing
but used a series-pass transistor for the current. In fact, it now handles
both fans. The thermistor is next to a heatsink in the power supply but is
cooled (or heated) by incoming air also. I added a trimmer to the circuit
and adjusted by trial-and-error. I also added a fail-safe diode to always
keep 6.3V on the fans in the event of failure. In the morning, it reads 85
deg with the fans at 6.3V. When using it, it rises to about 88 deg with a
fan voltage of about 9.5V. It hits 12V at 92 deg and will go to 15.6V if the
temp is high enough. The reason this is possible is the negative comes from
the -5V supply. This is the way the original was too. Now it's pretty quiet
when It's not being used.
