[LLVMdev] [lldb-dev] [cfe-dev] What does "debugger tuning" mean?
In some cases we do want to make the decision based on the target. For Hexagon, we don't support GDB anymore, only LLDB, so we always want LLDB tuning. The clang driver should have a way to specify that. -- Qualcomm Innovation Center, Inc.

listing components of an object
Is there a method to list the components of an object, instead of looking at the help for that method? Let me be more clear with an example data(iris) ## tune `svm' for classification with RBF-kernel (default in svm), ## using one split for training/validation set obj <- tune(svm, Species~., data = iris, ranges = list(gamma = 2^(-1:1), cost = 2^(2:4)), tunecontrol = tune.control(sampling = "fix")...

[LLVMdev] [lldb-dev] [cfe-dev] What does "debugger tuning" mean?
Comments on the patch raise the following questions, probably better discussed here. First: Should LLVM default to "no tuning" rather than a target-specific default? There are two natural follow-up questions: What would "no tuning" actually mean? Where would the target-specific defaulting occur? I originally came down against the "no tuning" option, in favor of the

...ent architecture complexity requires fine tuning of compiler and runtime parameters to achieve full potential performance. Autotuning substantially improves default parameters in many scenarios but it is a costly process requiring a long iterative evaluation. We propose an automatic piecewise autotuner based on CERE (Codelet Extractor and REplayer). CERE decomposes applications into small pieces called codelets: each codelet maps to a loop or to an OpenMP parallel region and can be replayed as a standalone program. Codelet autotuning achieves better speedups at a lower tuning cost. By grouping c...

(package e1071) SVM tune for best parameters: why they are different everytime i run?
Hi, I run the following tuning function for svm. It's very strange that every time i run this function, the best.parameters give different values. [A] >svm.tune <- tune(svm, train.x, train.y, validation.x=train.x, validation.y=train.y, ranges = list(gamma = 2^(-1:2), cost = 2^(-3:2))) # where train.x and train.y are matrix specified. # output command: >svm.tune$best.parameters$cost &g...

e1071 SVM one-classification tune problem
Hello all, I am using the e1071 SVM with the tune options for classification, which work pretty well, given the examples of using tune.svm function for classification. But I have not found any example to tune the SVM novelty detection (one-classification) parameters (gamma, cost, nu), for example this are some of the options I have tried with no s...

help with tune.svm() e1071
Hi, I am trying to use tune.svm in e1071 package. the command i use is tobj <- tune.svm(labels, data= data, cost = 10^(1:2)) Should the last column of the 'data' contain the labels as well? I want to use the linear kernel. But it gives me the error "Error in model.frame.default(formula, data) : 'data'...

[LLVMdev] What does "debugger tuning" mean?
This is basically a reboot of the previous thread titled About the "debugger target" except that "target" was really too strong a term for what I had intended to use this feature for. "Debugger tuning" is more like it. You don't need to have read the previous thread, I'll recap here. Fundamentally, Clang/LLVM uses DWARF as the specification for the

[LLVMdev] [cfe-dev] What does "debugger tuning" mean?
Another example would be .debug_pubnames and .debug_pubtypes sections. Currently these default to omitted for Darwin and PS4, but included everywhere else. My initial patch for "tuning" changes the PS4 platform criterion to the SCE debugger predicate; quite likely the "not Darwin" criterion ought to be "not LLDB" or in other words "on for GDB only."
