We're having more trouble with BigPapa. This means you can log in to the
lab's servers, but you won't have access to your home or data
directories. We'll update you as find out more. Right now it just wouldn't
talk to the server at some very low level. We already told it that counts
as "being naughty".

BigPapa is back online now. Apologies for the inconvenience. We're ordering
some new SCSI cables for it.

Hello,

Some of you have complained in the past about the abnormal slowness of IDL
on the GNU/Linux Alphas for certain (maybe all) operations.  That problem
has been fixed, hopefully completely.  Bob is happy, so we're happy.  Let
me know if you are not happy.  Please respond to user at autonlab.org.

  Paul, I was unable to send to user at autonlab.org from my machine

Could you forward this to the mailing list?

Dear Paul  and others,
  Something definitely changed on the auton linux-alphas.
My code seems to run faster than it use to. But note that it
never runs fast (i.e. it is typically as fast as on my 1Ghz Pentium).

However, I started a code earlier today and noticed something
had changed within the last couple of hours: I went from running
pretty fast, to a dead crawl. I have suspended the code (while
still in IDL) and when I type: print, sin(whatever), it takes a full second
to calculate.  That same command runs instantaneously on Crazy.

It *wasn't* having the problem a couple of hours ago (i.e. the
code got about half-way done before this started happening).

Any ideas? Anything in the kernel logs look funny?

Chris

Hi Chris,

The problem we're having with IDL is that the GNU/Linux Alpha version
keeps triggering unaligned exceptions.  It's not completely clear whether
these are the fault of IDL or something in Linux (the kernel).  That said,
IDL is currently causing (directly or indirectoy) many hundreds of these
exceptions right now, which explains your slow-down.

I'm not sure what to do or say.  Here are some options:

1) Changing Linux kernels has helped in the past (making it look like the
kerenls are guilty).  We're already current with the kernels, but could
try an older kernel (while hopefully avoiding the weekly-scsi-error-fest
we had with many of the older kernels).

2) We could reinstall Tru64 on Limey.  However, nobody seemed to like
Tru64 -- limey/Tru64 was only used for occasional IDL and scp tasks over
the last several months and never registered any significant or continued
load (except for some of my doing).

3) We could complain to the IDL folks.  They have a new version of IDL out
for every platform they support (it seems), except for GNU/Linux on Alpha.

I'd appreciate suggestions.  For the record, #2 is my least favorite
because

a) I'd like to standardize on GNU/Linux for the Alphas and hence avoid the
hours of extra work I've put in adapting admin stuff to Tru64, not to
mention changing my personal stuff from time to time as well as the AUTON
lab's build scripts,

b) It seems a big waste to use limey only for IDL and scp, as it has been
used for the last several months with Tru64 (even when the GNU/Linux
Alphas have been slammed).  We bought for over $40,000 and currently sells
for over $10,000.  Limey has a nice big 64 bit address space, 4GB of ram,
and a 4MB cache.  Sustaining an average load of 0.00 is a bit silly.

Hi All,

Someone help me before with ascii to fds conversion (thanks).
I need to do it again but dont want to bug someone everytime
I need this. Is there a script (c or f77 program) to do this?

I have "fdsconvert.pl" in one of my directories 
(/mnt/BigPapa/home/nichol/npt/GIFparticles) but it doesnt seem
to produce a .fds file??

Cheers

Bob

Hi Bob,

1) get dset

If you have access to AUTON source, you should check out the dset project
and build it (it depends on the utils probject).  I can help you with
that to some extent.

In case you don't have or want the source, I copied the dset executable to
your home directory.  It is called (surprise) dset.

2) run dset

if your input (text) file is foo.txt, do

  ./dset edit in foo.txt

3) save as fds

from the dset prompt, do

  save foo.fds

4) quit

  type 'quit' to quit from dset

If the input filename ends in .txt or .csv, it will be read in some
sensible way for an ascii file.  When you save, if you save to a filename
with .fds as the extension, then you'll get an fds file.  Of course, you
can to the opposite, too:

  ./dset edit in foo.fds
  save foo.txt
  quit

Thanks Paul,

Actually, I was wondering if there was a simplier alternative
like the "fdsconvert.pl" code some put in my dir. It seems to
work apart from it just prints the screen. Is the fds format
hard to understand.

Actually, another option is for me to use someone elses dset;
can someone point me to theirs?

Cheers

Bob

Hi Bob,

If the perl script is writing to screen, maybe you just need to redirect
it into a file:

  fdcconvert.pl foo.txt > foo.fds

As far as "someone else's dset", they're all going to be the same as the
one I put in your home directory.  dset isn't my software, and I haven't
customized it at all.

So here's what I did for you, Bob.  There's a new executable in your home
directory called dsetconvert.  It only does one thing: convert between
text and fds.

  ./dsetconvert foo.txt foo.fds

or

  ./dsetconvert foo.fds foo.txt

Furthermore, it's written in C and compiled with optimizations, so it will
be fast on large datasets.  The only way it's going to get any simpler is
if you hire an undergrad. ;-)

-Paul
