[LLVMdev] GPU thread/block/grid size contraints in LLVM PTX backend
I am wondering that how does the LLVM PTX backend find out the
constraints on executing GPU thread/block/grid size ( i.e. a block can
at most have 1024 threads). Can anyone point me to the code ? I need
information in the optimizer, how can I get it ?
Thanks

[LLVMdev] GPU thread/block/grid size contraints in LLVM PTX backend
You specify shader model, bit size and etc. arch-specified parameters
though -march, -mattr and -mcpu, but AFAIK, PTX backend does not use
the GPU thread/block/grid size information in optimization yet.

Does a mock model have to satisfy contraints
I am a little confused to the what happens with the following:
before do
@site = mock_model(Site, :to_param => "1")
Site.stub!(:new).and_return(@site)
end
def post_with_successful_save
@site.should_receive(:save).and_return(true)
post :create, :site => {}
end
I understand that the "@site.should_receive(:save)..." places a check to

To find vector X under contraints
Hi R,
I have the variance-covariance matrix,
>V=matrix(c(0.011119238, 0.002407527, 0.002407527, 0.020739401),2,2)
I need to find a vector X=c(x1,x2), such that
1) X'VX is equal to a constant 2 (say) and
2) sum(x) should be equal to a another constant 1.5 (say).
How do we do this in R?

Hi Jakob,
That's a good point. I'll factor out the problem builder in the next couple
of days and drop a mail to the list explaining how to write extensions.
Cheers,

I don't think so, but you should check source code.

optim with contraints
There seems to exist peculiar cases where optim does not take care
of constraints on the parameters to be optimized over. The call to
optim is of the form
opt <- optim(cp, fn=sn.dev, gr=sn.dev.gh, method="L-BFGS-B",
lower=c(-Inf, 1e-10, -0.99527),
upper=c( Inf, Inf, 0.99527),
control=control, X=X, y=y, hessian=FALSE)
The code has worked fine

[LLVMdev] Complex regalloc contraints
Hi all,
The machine I am targeting has some special requirements for some
operations, say:
ADD or1, ir1, r5
would add ir1 (input reg 1) and r5 and put the result in or1 (output reg
1). The point id that input and output regs have to go paired (this
meaning an addition of ir1 with whatever always goes to or1, or an in
general irX + whatever goes to orX).
AFAIK, InstrInfo.td only allow

constrained optimisation in R.
i want to estimate parameters with maximum likelihood method with contraints (contant numbers).
for example
sum(Ai)=0 and sum(Bi)=0
i have done it without the constraints but i realised that i have to use the contraints.
Without constraints(just a part-not complete):

n=length(z);

H=parameters[2];

[LLVMdev] Complex regalloc contraints
Hi Carlos, Jakob,
The PBQP allocator was designed to support a very wide range of constraints,
and can handle something like this easily.
Say you have 4 of these orX/irX registers, then for any pair of virtual
registers used in such an add instruction you would add the following
constraint matrix to the PBQP instance:
[ 0 inf inf inf ]
[ inf 0 inf inf ]
[ inf inf 0 inf ]
[ inf inf inf 0

constrained OLS on coefficient
Hi,
I would like to know if anyone has any idea of how to run an OLS with
constraints? I need to contraint a coefficient estimate in the model equal to
1, and I am not sure how to include it into the OLS estimation...
I was hoping to find something like "cnsreg" in STATA..
thank you

How to obtain restricted estimates from coxph()?
Hello,
I'm trying to use coxph() function to fit a very simple Cox proportional
hazards regression model (only one covariate) but the parameter space is
restricted to an open set (0, 1). Can I still obtain a valid estimate by
using coxph function in this scenario? If yes, how? Any suggestion would be
greatly appreciated. Thanks!!!

Constrain coefs. in linear model to sum to 0

of classical corner contraint i.e. I would like to fit a model like

and say get parameters

effectA_1
effectA_2
effectB_1
effectB_2

where effectA_1 represents deviation of level A_1 from intercept and
sum(effectA_1, effectA_2) = 0 and the same for factor B.

Migrations - use them or not?

As a rails newbie, i have stumbled upon some tutorials promoting

However, now that i am reading the RoR list on a daily basis, i have

[LLVMdev] [REQUEST FOR FEEDBACK] Inline asm multiple alternative constraints

value info in the operands from the callsite object is sufficient to choose
the constraints. I also added some other virtual functions to
TargetLowering to allow the different targets to handle the target-specific
contraints. At present, I only overrode the getSingleConstraintMatchWeight
function in X86TargetLowering, and just for one constraint letter, as an
example.

Going to production soon, need server advice
...ssible Mac OS X
Server. Currently I''ve been looking at Litespeed and their LSAPI
integration and am tempted by that. I also have looked at Mongrel with
Pound/Pens/Balance. I *could* do Apache 2.2 and Mongrel but want to
avoid Apache if possible as I''d like to keep my memory contraints as low
as possible and I''ve found Apache can be a bit of a memory hog (perhaps
its my configuration - but I just don''t care to use Apache if need be).
Thanks for all the feedback.

Force logonserver in samba4
Hi everybody.
We have a samba4 domain deployed across serveral countries. Some of them
(overseas) have a poor VPN connection with mainland.
Since Samba4 does not support (yet) subtrees, we have deployed a DC in
each location for domain validation. However users in mainland logon
randomly at overseas location and sometimes this is a problem due to low
bandwidth available.
Is there any way to
