That really is a great article, I think one of the ways Intel is going to work around this is multi process chips... so things that aren't as performance intensive are going to be made on older faster cheaper processes, or more optimized processes. So they can make IO optimized drivers for high speed ram interfaces, logic optimized areas for the CPU, and low cost peripheral areas. It is certainly interesting to see companies trying to cope with the limits they are running up against. As well as they can conentrate on making only one sub unit faster per generation... rather than thier tick - tock tock they have been doing. They could do some iteration on aspects of the design without having to worry about parts that won't change getting broken by moving to a new process etc.. .
I've seen some ideas about die stacking of CPU and GPU components instead of chips ram as is done with HBM. So, perhaps they would make tiny very high yeild dies, but stack a bunch of them and run them rather slowly for a higher aggregate speed so they don't fry themselves with heat.
As an aside I've actually seen Daifuku (Wynright is the specific branch I've worked with) equipment installed in several locations where I have been out on an on site setup trip for the equipment my employer makes... very cool cranes (I've seen them shuffling shoe boxes and potato chips) though apparently they shuffle computer chips around as well!
Hello,
i'm trying to implement the times() function and i'm programming in C.
I'm using the "struct tms" structure which consists of the fields:
The tms_utime structure member is the CPU time charged for the execution of user instructions of the calling process.

Hi,
I am new in this forum and I am glad to be a part of it. I have a problem that has two parts:
1/ extract just the timestamp from a filename: for example, I have a file called 'sales20080226144525.txt' and I want to extract just the '20080226144525' part out of it.
2/ Now, take that... (5 Replies)
hi!,
here is an interesting problem .....
I ftp a file named " my first file.doc" from windows to my HP workstation.
Ftp is succesful. The file appears with the same name in my home directory.. But now how do I open this file??
while using Vi or More or other editor, they take only the... (5 Replies)
EXPIRE.CTL(5) File Formats Manual EXPIRE.CTL(5)NAME
expire.ctl - control file for Usenet article expiration
DESCRIPTION
The file /etc/news/expire.ctl is the default control file for the expire(8) program, which reads it at start-up. Blank lines and lines
beginning with a number sign (``#'') are ignored. All other lines should be in one of two formats.
The first format specifies how long to keep a record of fully-expired articles. This is useful when a newsfeed intermittently offers older
news that is not kept around very long. (The case of very old news is handled by the ``-c'' flag of innd(8).) There should only be one
line in this format, which looks like this:
/remember/:days
Where days is a floating-point number that specifies the upper limit to remember a Message-ID, even if the article has already expired.
(It does not affect article expirations.)
Most of the lines in the file will consist of five colon-separated fields, as follows:
pattern:modflag:keep:default:purge
The pattern field is a list of wildmat(3)-style patterns, separated by commas. This field specifies the newsgroups to which the line is
applied. Note that the file is interpreted in order, so that the last line that matches will be used. This means that general patterns
(like a single asterisk to set the defaults) should appear before specific group specifications.
The modflag field can be used to further limit newsgroups to which the line applies, and should be chosen from the following set:
M Only moderated groups
U Only unmoderated groups
A All groups
The next three fields are used to determine how long an article should be kept. Each field should be either a number of days (fractions
like ``8.5'' are allowed) or the word ``never.'' The most common use is to specify the default value for how long an article should be
kept. The first and third fields -- keep and purge -- specify the boundaries within which an Expires header will be honored. They are
ignored if an article has no Expires header. The fields are specified in the file as ``lower-bound default upper-bound,'' and they are
explained in this order. Since most articles do not have explicit expiration dates, however, the second field tends to be the most impor-
tant one.
The keep field specifies how many days an article should be kept before it will be removed. No article in the newsgroup will be removed if
it has been filed for less then keep days, regardless of any expiration date. If this field is the word ``never'' then an article cannot
have been kept for enough days so it will never be expired.
The default field specifies how long to keep an article if no Expires header is present. If this field is the word ``never'' then articles
without explicit expiration dates will never be expired.
The purge field specifies the upper bound on how long an article can be kept. No article will be kept longer then the number of days spec-
ified by this field. All articles will be removed after then have been kept for purge days. If purge is the word ``never'' then the arti-
cle will never be deleted.
It is often useful to honor the expiration headers in articles, especially those in moderated groups. To do this, set keep to zero,
default to whatever value you wish, and purge to never. To ignore any Expires header, set all three fields to the same value.
There must be exactly one line with a pattern of ``*'' and a modflags of ``A'' -- this matches all groups and is used to set the expiration
default. It should be the first expiration line.
For example,
## How long to keep expired history
/remember/:5
## Most things stay for two weeks
*:A:14:14:14
## Believe expiration dates in moderated groups, up to six weeks
*:M:1:30:42
## Keep local stuff for a long time
foo.*:A:30:30:30
