Time For A Cray Comeback?
Boone^ writes "The New York Times has an article (free reg. req.) talking about Cray Inc.'s recent resurgence in the realm of supercomputing. It discusses a bit of Cray's decline when the Cold War ended, "the occupation" under SGI, and the rebirth of the company after the Tera (now Cray Inc.) purchase. Recently Cray Inc. has been shipping their vector-based Cray X1 machine, designing ASCI Red Storm, and recently was one of 3 (also Sun, IBM) to win a large DARPA contract (PDF link) to design and develop a PetaFlops machine by 2010. Could Cray Inc. be poised for a comeback? Wall Street seems to think so."

Gentlemen, the time has come for a serious discussion on whether or
not to continue using C for serious programming projects. As I will
explain, I feel that C needs to be retired, much the same way that
Fortran, Cobol and Perl have been. Furthermore, allow me to be so bold
as to suggest a superior replacement to this outdated language.
To give you a little background on this subject, I was recently asked
to develop a client/server project on a Unix platform for a Fortune
500 company. While I've never coded in C before I have coded in VB for
fifteen years, and in Java for over ten, I was stunned to see how
poorly C fared compared to these two, more low-level languages.
C's biggest difficulty, as we all know, is the fact that it is by far
one of the slowest languages in existance, especially when compared to
more modern languages such as Java and C#. Although the reasons for
this are varied, the main reasons seems to be the way C requires a
programmer to laboriously work with chunks of memory.
Requiring a programmer to manipulate blocks of memory is a tedious way
to program. This was satisfactory back in the early days of coding,
but then again, so were punchcards. By using what are called
"pointers" a C programmer is basically requiring the computer to do
three sets of work rather than one. The first time requires the
computer to duplicate whatever is stored in the memory space "pointed
to" by the pointer. The second time requires it to perform the needed
operation on this space. Finally the computer must delete the
duplicate set and set the values of the original accordingly.
Clearly this is a horrendous use of resources and the chief reason why
C is so slow. When one looks at a more modern (and a more serious)
programming language like Java, C# or - even better - Visual Basic
that lacks such archaic coding styles, one will also note a serious
speed increase over C.
So what does this mean for the programming community? I think clearly
that C needs to be abandonded. There are two candidates that would be
a suitable replacement for it. Those are Java and Visual Basic.
Having programmed in both for many years, I believe that VB has the
edge. Not only is it slightly faster than Java its also much easier to
code in. I found C to be confusing, frightening and intimidating with
its non-GUI-based coding style. Furthermore, I like to see the source
code of the projects I work with. Java's source seems to be under the
monopolistic thumb of Sun much the way that GCC is obscured from us by
the marketing people at the FSF. Microsoft's "shared source" under
which Visual Basic is released definately seems to be the most fair
and reasonable of all the licenses in existance, with none of the
harsh restrictions of the BSD license. It also lacks the GPLs
requirement that anything coded with its tools becomes property of the
FSF.
I hope to see a switch from C to VB very soon. I've already spoken
with various luminaries in the C coding world and most are eager to
begin to transition. Having just gotten off the phone with Mr. Alan
Cox, I can say that he is quite thrilled with the speed increases that
will occur when the Linux kernel is completely rewritten in Visual
Basic. Richard Stallman plans to support this, and hopes that the
great Swede himself, Linux Torvaldis, won't object to renaming Linux
to VB/Linux. Although not a C coder himself, I'm told that Slashdot's
very own Admiral Taco will support this on his web site. Finally,
Dennis Ritchie is excited about the switch!
Thank you for your time. Happy coding.
could i have a beowulf cluster consisting of an athlon 1.1, a celeron 500, and my wife's k6-2 450?
/. what kind of processing power would i have between these 3 machines? ~a 2ghz athlon or p4? (that's just adding the MHz together) or is it a more geometric equation such that it'd be faster than a 3ghz p4?
i understand the concept of clustering but i've never really read anything about it other than stuff here on
-PsychoI3oy
mmm freeBSDelicious.
85 replies, even the trolls, and not one "Imagine a beowulf cluster of these" post.
Can't a guy count on slashdot for anything anymore?
