List gurus, I'm trying to code a Gompertz growth curve function as part of a larger project and have run across a problem due to my ignorance of environments. Some sample data and the function are as follows: growth <- data.frame(age = c(1.92, 3, 5.83, 3.17, 15.5, 1.17, 5.58, 13.33, 14.29, 5.83, 13.79, 6.33, 13.75, 16.83, 13, 11...

Hi Duncan Sands, As I have understood, GOMP and OpenMP provides support for parallelizing program at source program level. But I am at the IR level. That is I am trying to parallelize the IR code. This is the case of automatic parallelization. The programmer writing the code does not have any idea of parallelization going behind the hood. S...

Hi, I want to execute the iterations of a loop in parallel, by inserting calls either to pthreads or to the gomp library at the LLVM IR level. As a first step, I inserted an omp pragma in a C file and compiled it with llvm-gcc to check the generated LLVM code. If I understand correctly, to parallelize the loop in LLVM IR, I have to separate the loop in a new function, put all required parameters in a structur...

Hi, I would like to ask which version of OpenMP is supported by DragonEgg and at which extent(i.e. fully, partially etc.).

Hi All, I am new to LLVM. So please help me out. Here is what I am trying to achieve: If there are 2 statements in a source program - S1; S2; and I know these is no data and control dependency between them and both take large amount of time to execute. So I want to execute them in parallel. So as S1 starts executing, I want to launch another thread and

...mantics of the used parallel representation. While this sounds tedious at first, it turns out that we can perform key optimizations with reasonable implementation effort (and thereby also reasonable maintenance costs). However, we have various parallel representations that are already in use (KMPC, GOMP, CILK runtime, ...) or proposed (Tapir, IntelPIR, ...). Our proposal seeks to introduce parallelism specific optimizations for multiple representations while minimizing the implementation overhead. This is done through an abstract notion of a parallel region which hides the actual representation...
