Hello all,
I am new to Cactus and it is not clear to me where the limitations of  
Cactus are.
The Cactus users guide sometime talks about a "grid" and "grid  
points" etc. From this I got the impression that thorns always  
operate on some kind of uniform lattice. Is that true?
I am looking for a framework which can connect different legacy  
simulators, e.g. a car traffic simulation and a pedestrian movement  
simulation. Is Cactus suited for such things?

Many TIA,
-- Jan

Jan,

I use Cactus for discrete quantum gravity computations, which bear
little resemblance to simulations on a uniform lattice.  The 1d "grid
arrays" are really quite general objects -- I use them to store
partial order relations and some information regarding how an abstract
graph embeds into a 3 dimensional manifold.  In addition I have
developed a prototype "unstructured mesh driver" in Cactus, which in
principle allows computations on extremely general structures.  Such
things are heavily used in computational fluid dynamics.

The documentation is indeed written from the perspective of finite
difference solutions of PDEs on a regular lattice, so it is worded
accordingly.  This needn't put you off from using it for more general
computations, however.  I understand that Cactus 5 is directed toward
providing a more general framework, e.g. by allowing abstract data
types beyond CCTK_REAL, CCTK_INT, etc.  This version may remove some
of the assumptions of finite differencing on a regular lattice from
the documentation.

I'd be happy to discuss your applications in more detail if you like.

Regards,
David Rideout

Is there a release date for Cactus 5?

So currently one is restricted to primitive datatypes? Sending C++  
Objects is not possible? Sounds like MPI to me (-;

Well, I am looking for a mature framework which we can extend to  
couple various legacy (and also new) simulations, mostly cellular  
automata.
I am just not sure if Cactus is suitable. Is it possible to execute  
the thorns on different machines and architectures? e.g One thorn on  
a linux hpc cluster, another on a local machine, another distributed  
on a grid.
Is it possible to establish a peer to peer connection between thorns,  
or does one have to use the flesh for this?

Cheers,

No.  I believe it is still in the planning stage.  Though prototype
codes do exist, such as the one I mentioned earlier.

The Cactus variables passed to functions via CCTK_ARGUMENTS are
restricted to these types, though you can attach anything you like to
a "cGH" pointer which is also passed to all functions called by the
flesh.  The communication is handled by a Cactus "driver".  The
currently available drivers, as far as I know, only communicate these
standard data types.  You are free to write your own driver, however.

I would guess that the integer grid functions of Cactus are well
suited for cellular automata.

The particular parallel scenario you describe sounds like what we
refer to as a "multi-model" simulation.  You have different physics in
different regions, and may want to run those different regions on
different machines, while still allowing the various models to
communicate.  This is something that comes up in climate modeling as
well, so I know that people have been thinking about this in the
context of Cactus.
Something like this has been done for binary black hole simulations
with Cactus using globus for the MPI layer.
Perhaps others on the list will know more about the current status.
Generic support for these sorts of simulations is planned for Cactus
5.  (Or perhaps 4.1, see
http://www.cactuscode.org/Development/current.html.)

Cheers,
David

There is some prototype multi-model support in the Carpet driver.   
For example, you may want to solve the full Einstein equations in the  
nonlinear regime, and solve a linearised version in the far-field.   
In the prototype, one is essentially running independent simulations  
(with different active thorns, different parameter setting etc.),  
which communicate through boundary conditions.  The communication  
happens via what Cactus calls "hyper-slabbing", which is exchanging  
of data in rectangular or cuboidal regions.

However, we don't use that in production mode yet, so that it is  
likely still inconvenient to use, or still has errors.

Hi.  When I try to run the GetCactus script, the cvs requests always  
seem to hang, and nothing happens...

I'm behind a firewall at my university, but they claim they don't  
block outbound port requests (e.g. port 2401 for pserver access).

Does anyone have a suggestion so I can get code from the Cactus cvs  
repository?

Thanks,

Hi Scott
I have just checked the cactus cvs server, everything seems fine. As I 
am in LSU, I will run more tests from off-campus to make sure. An 
alternative method to checkout Cactus would be the nightly tarball:

I hope this helps

Thanks Yakoub...  I'm guessing the problem really *is* on my (or my  
university's) end, not something wrong with the Cactus repository.   
But what should one "look at" locally when fixing this sort of  
thing?   I'm running on a fairly new Linux box running RHEL 9, and  
behind some kind of ^$%^&in firewall.
Thanks.

My guess would be the firewall but I am asking our sys admins if they 
know something that I don't.

You can test that. Type

telnet cvs.cactuscode.org 2401

If you see something like the following, it means that they are right.

Trying 130.39.186.101...
Connected to asylum.cct.lsu.edu.
Escape character is '^]'.

If this also hangs, you are likely to have a routing/firewalling problem 
and should go to your sysadmins.

[[My first attempt to send this bounced.]]

Hi Scott,

Have you tried ssh port forwarding?  i.e. tell your cvs client to use
the cvs server on your local machine, and then forward that port to
cvs.cactuscode.org via ssh.  I forget the command to do this at the
moment but you can probably sort it out.  Or someone else on the list
may explain.  A problem is that you will have to switch the port
forwarding for each different cvs server (repository?) you use.  But a
script might make this not too painful.

Cheers,
David

Thanks David.  I actually already have "setenv CVS_RSH ssh" set.  I  
see one problem in that GetCactus uses pserver instead of "ext"  
access, and another problem in that I don't actually have a valid  
login at cvs.cactuscode.org in order for ssh to work.
-Scott

Thanks Frank.  Yea, the telnet command hangs too.  I'll talk to the  
network admin!

Do you have access to a machine outside of your firewall that you 
could set up a tunnel via ?  I.e. you'd still use pserver but use a tunnel 
out of your network.

Cheers,

Tom

Greetings
As some of you are aware, we have a thorn in CCTDevelopment called SPRNG 
which provides a very basic interface to the SPRNG: Scalable Parallel 
Random Number Generator library. Yesterday we had the good fortune of 
having one of the developers here at CCT. Since this is a subject that 
interests a lot of users and developers, we have now have the SPRNG 
seminar up online at:
http://www.cct.lsu.edu/~deilands/11-29-2006.zip
To view this file you will need to obtain the AGVCR tool (Access Grid 
Video Cassette Recorder) available here:

Cheers
Yaakoub
