Hello, I'm trying to adjust a non linear model in which the biological response variable (ratio of germinated fungus spores) is dependent on 2 covariates (temperature and time). The response to temperature is modeled by a kind of beta function with 2 parameters (optimal and maximum temperatures) and the time function is a 2-parameter Weibull. Adjustments with nls or gnls work, but I need to

Hi, I have R 2.6.0 with updated lme4 and Matrix packages, and I am trying to fit a nonlinear multilevel model. I get the following error message: Error in nlmer(f ~ grModel(x, w, Tmin, Tmax, Topt, kopt, m) ~ kopt | flat, : gradient attribute of evaluated model must be a numeric matrix and I wonder what this may indicate. The nonlinear model I try to fit is as follows: > grModel function(x,w,Tmin,Tmax,Topt,kopt,m)((x-Tmin)*(x-Tmax))/((x-Tmin)*(x-Tmax)-(x-Topt)^2)*kopt*w^m and my c...

Hi edaqa, You might need to set your TargetOptions before calling selectTarget. E.g. builder.setTargetOptions(Opts).selectTarget(...); Or you could just let EngineBuilder call selectTarget for you (which is what the no-argument version of EngineBuilder::create does): llvm::ExecutionEngine * ee = builder. setErrorStr( &errStr )....

My code to create an ExecutionEngine is segfaulting: std::string errStr; llvm::ExecutionEngine * ee = llvm::EngineBuilder( unique_ptr<llvm::Module>(module) ) .setErrorStr( &errStr ) //line 1618 .setEngineKind( llvm::EngineKind::JIT ) Where module is a `llvm::Module*`. This is code I'm migrating from 3.3 to 3.8. Since the deletion error is happening during

Hi, I wrote a small script in order to stress test llc using test cases generated by llvm-stress. When it finds a case where llc seems to have crashed, it greps the output for Assertion, LLVM ERROR, etc., removes things that look like hex numbers and ID numbers, and then checksums the resulting text. In this way, it can automatically categorize different bugs into different subdirectories. I

Hi, Could you share how you compile IR and which version of JIT you use (Orc, MCJIT)? Could it be that you are using interpreter instead of actual JIT? Cheers, Alex. > On 5.

I'm having issues of my compiler, and JIT execution, of LLVM IR being rather slow. It's accounting for the vast majority of my full compilation time.  I'm trying to figure out why this is happening, since it's becoming an impediment.  (Note: by slow I mean about 3s of time for only about 2K of my front-end code, 65K lines of LLVM-IR) Using valgrind I see some functions which seem

Dear all, In the process of trying to add optimization for better layout of global variables, I have run up against a roadblock: I don`t seem to be able to sort the contents of a "SymbolTableListTraits<GlobalVariable>" -- or even swap two elements in that list -- without causing LLVM to crash. I have tried writing a comparator class and then using "llvm::iplist<
