Webinar: Super Easy RESTful Services Generation for MultiValue Databases
Tuesday, October 2, 2012
The latest release of mv.NET provides what is arguably the simplest yet most
powerful and flexible way of creating RESTful web services against a MultiValue
database.
Developers are now able to
I recently downloaded uv 11 and when I went to run STARTUP I got a weird
error, upon looking at the STARTUP script I noticed it had a bunch of binary
and other junk at the beginning of the file, I removed all the extra
stuff, saved the file and it ran just fine.
Has anyone else seen this? I

Have you remembered that STARTUP is a cpio archive?
# cpio -uvcdumB uv.load STARTUP
./uv.load

No sir, I did not know that, why would they cpio it anyway? Not that it
matters I was just curious, anyway thanks for the info.

What's the largest dataset in the Universe user world?
In terms of number of records.
I'm wondering if we have any potential for utilities that map-reduce.
I suppose you would spawn phantoms but how do they communicate back to the
master node?

The only thing about a pipe is that once it's closed, I believe it has to be
re-opened by both
Ends again. So if point a opens one end, and point b opens the other end, once
either end closes,
It closes for both sides, and both sides would have to reopen again to use.
To eliminate this, you
0001: OPENSEQ /tmp/pipetest TO F.PIPE ELSE STOP NO PIPE
0002: LOOP
0003:READSEQ LINE FROM F.PIPE ELSE CONTINUE
0004:PRINT LINE
0005: REPEAT
0006: STOP
0007: END
Although, not sure if you might need to sleep a litte between the READSEQ's
ELSE and CONTINUE
Might suck up cpu time when
So how would a user 'chop up' a file for parallel processing? Ideally, if
here was a Mod 10001 file (or whatever) it would seem like it would be
'ideal' to assign 2000 groups to 5 phantoms -- but I don't know how 'start a
BASIC select at Group 2001 or 4001' ...

Create an index on a dict pointing at the first character of the key, and have
each phantom take two digits. (0-1, 2-3, 4-5, 6-7, 8-9)

OK - I was trying to create a 'smoother use' of the disk and 'read ahead' --
this example the disk would be chattering from the heads moving all over the
place. I was trying to find a way to make this process more 'orderly' -- is
there one?

The GROUP.STAT.DETAIL command will tell you the keys, in stored order, in each
group of a hashed file.

True - but why would you want it any other way ?
Once one end closes it - process is complete

Or, let's suppose you wanted to process repetitive segments of one very
large record using the same logic in a separate phantom process for each
segment, how large a record can be read and processed in Universe?

So how would a user 'chop up' a file for parallel processing? Ideally, if
If the file were big enough, and already had part files, then I believe that
you could have a phantom process each of the individual parts. Failing that,
get an SSD relatively cheap, and will give your processing a reasonable
kick along!!

I have often thought about this - mostly in an idle moment or as a
displacement activity for something less amusing that I ought to be
doing. ;-)
First of all, Universe is already extremely parallel: there's a separate
O/S thread for each TTY and for each phantom, and you can't get more
parallel
Interestingly I'm currently trying to find a definitive answer/correlation
between clock speed performance on a single core/thread on Intel CPU's to
confirm, or deny, that for grunt batch work if a 4C Intel running @ 3.4Ghz will
actually be faster than an 8C running @ 2.7Ghz -- the answer
17 matches
