I am trying to transform CM fortran to run on hypercube
machine.  I need CM fortran programs, either working or
non-working, to analysis their data dependency. I
prefer that the purpose of those programs is to solve 
some problem, like linear system solver, etc.

Thank you for your kind help.

I've got a question on the true operating Bandwidth of the CM-2

I am attaching to an 8k subset and using a 2-d mesh shape. If I use the

 CM_send_to_news(&input,output,0,CM_upward,boolsizeof(char));

exactly how many message startups will be executed. What I mean is that
If I have a 128x64 shape so I have 8K vitural processors on 8k physical
processors, and I send a message 8 bits long, do I actually produce
8 message startups. Is the true operating bandwidth in this case 1 bit?

Also, since 16 processors sit on a chip, and then there are 12 hypercube
wire interconnects going off chip, is a mesh embedded in the array, or
do the messages that go from one chip to the chip physically sitting next 
to it on the board go through hypercube routing (which in some cases
is longer that 1 unit route, right?).

I know there is little point in arguing with press releases, but the
Cray Y-MP C90 is certainly available today, and has parallel processors,
and offers 1 Gigaflop per processor, so I don't see how 1.6 Gigaflops
per processor can be a 10x improvement.

Not to mention that the CM-5 goes up to 16000 processors and 2000
Gigaflops.  Don't these guys read each other's press releases?  :-)

Off the top of my head, the price-performance point of this system
doesn't seem very attractive, especially for this time period.  At $122M
for the full system, a number which Fujitsu mysteriously forgot to
mention in the press release, that looks like at best $350K/GF.
(Systems of realistic size would presumably be worse.)  Aren't large TMC
and Intel systems currently around $250K/GF, and available this year?

Of course, peak Gigaflops aren't the measure of a computer system, but
since they are the measure that Fujistu chose to use....

Perhaps Industry Analyst Gary Smaby knows something we don't.  Like what
those price/performance claims are.  What's the point of providing an
endorsement of the claims but not including the claims themselves?

Giovanni,

The phasing error is due the composition of two things:

(1) your code makes forward references to labels;

(2) later in the assembly stream, code is generated that resides
earlier in the memory of the 6811.  

Because AS11 makes only two passes on the code, it gets confused.  
This is a known problem (the phasing error) and is discussed in the
documentation for the AS11 assembler (the file ASEMBLER.DOC).

Here's what occured for your sample code: In the first pass, the
assembler has to figure out how large the arguments are for each
instruction so that it can resolve forward label references.  The
trouble is with the label 'led-on'.  In the first pass, the assembler
assumes the "JSR led-on" will require three bytes (one byte
instruction, two bytes data).  But then it discovers (after your ORG
$0000 puts 'led-on' in the zero page) that the 'led-on' label can be
expressed in one byte.  When it goes to fill in the label values, it
seems to optimize this value to fit into one byte, generating the
error.

If you structure your assembly source code so that all code is
generated in increasing order of location in the 6811 memory map, AS11
should do fine.

The only other 6811 assembler I've used is *not* freeware, but it does
deal with this problem by having the capability to make an arbitrary
number of passes on the source code until forward references and code
placement are resolved.  It's named ASM11 and is sold by Dunfield
Development Systems, Inc. (phone: 613-256-5820).

Subject: Stepper Motor Help !!
Date: 12 Sep 92 19:27:39 GMT
Organization: Computer Science Department, Texas A&M University

This is a question for stepper motor gurus out there. We recently bought a few
stepper motors with gearboxes from a surplus parts store for a project. We've
been trying to drive the motors and have run into a problem. I've described it
below :

The motor looks like this (from one side)

---------------------------
|         |           |   |
| ||||    | ||||      |   |==== shaft is about ----> axis.
| ||||    | ||||      |   |
--||||------||||-----------
  ||||      ||||
  BWRY      BWRY

The motor has got two connectors on it with 4 wires each, labelled (B)lue,
(W)hite, (R)ed and (Y)ellow. The B and W wires are shorted on each connector.
What we did was to ground the BW wire and pulse the R and Y in sequence. We
found out that the connector on the right drove the shaft forward, while that
on the left drove the shaft backward. We also discovered that the motor would
not run if any combination of the right and left connectors was pulsed. In
other words, we needed to energize the right connector's wires to move forward
and the left connector's wires to go back.

Our problem is that when we apply a torque on the motor shaft, the motor
sometimes starts rotating in the opposite direction!! The torque is pretty high.

Does anyone have any ideas on a better way to drive the motor (I mean
connections, pulse sequence, etc) so that we can develop more torque and
prevent this problem of direction reversal?

Please reply by email to charath@cs.tamu.edu

Have you played with any LEGO Technic (TM) parts lately?  They are

I take exception to your inference that Fischertechnik is

Hi

I haven't seen any posting about bugs in the freeware assembler.
I have seen mention of newer version (AS11NEW.EXE), but I
can't find it on ARCHIE and dialling into the FREEWARE BBS from New
Zealand is a prohibitively expensive.

  o Is there something I should know about the assembler or are these
       know errors?

  o Is there a better FREE assembler, especially in terms of error
    reporting? If you generate a list file you have no idea of whether
    there were any errors without viewing the whole file!

  o Is there a later version than this: AS11     EXE    18906 26-02-88 12:54p

If you could give me the FTP address of a site with an assembler that doesn't
exhibit these oddities I'd really appreciate it.

Thanks

	Is anyone using (or considering using) Echelon's Neuron chip for
robotics work ? It seems to be well suited for the task, especially for
complex designs where a number of micro-controllers would be used, since
it incorporates hardware and firmware to support networking via different
media. (ex twisted pair, RF transceivers)
