similar to: looking for a better way to code a bar graph

Hello, I am trying to plot means and standard errors conditioned by a factor, using qplot. I am successful at getting the bar graph I want with a error bar, however I have tried many things and cannot get the bars to change colors. Currently showing as red and blue, but need it to be black and white for publication. Any suggestions please? Using a data set June, which is str:

Thanks for the heads up Philip ! I did come across a strange case where LLVM allowed "%" to be a part of a function's name. This was in the context of my patch https://reviews.llvm.org/D33985, where I prefix the name of the source function and the Scop ( A special kind of Region that Polly can optimize, the name of the Scop is the name of the Region ) to the name of the PTX kernel

Ok, so I moved the OpenMP, GPGPU, and MemAccess dirs to the toplevel polly/test/{OpenMP,GPGPU,MemAccess} and then the remaining testcases to

Hi all, I am a phd student from Huazhong University of Sci&Tech, China. The following is my GSoC 2012 proposal. Comments are welcome! *Title: Automatic GPGPU Code Generation for LLVM* *Abstract* Very often, manually developing an GPGPU application is a time-consuming, complex, error-prone and iterative process. In this project, I propose to build an automatic GPGPU code generation framework

Well, after many months of effort, my LLVM-based garbage collector is finally passing its unit tests. This represents a significant milestone for me in the development of my programming language, Tart. The collector itself is fairly rudimentary - a single-generation, copying collector. It does not yet support multi-threaded programs, but in practice there's no serious obstacle to supporting

Hi All, I have been reading about general purpose GPU (graphical processing units) computing for computational statistics. I know very little about this, but I read that GPUs currently cannot handle double-precision floating points and also that they are not necessarily IEEE compliant. However, I am not sure what the practical impact of this limitation is likely to be on computational

Hello everyone I was wondering, what the correct way of using an AMDGPU generated kernel code for OpenCL was. I am trying to provide Polly's GPGPU Code generation with the ability to run on different GPU devices, such as AMD GPUs. For NVIDIA, I simply retrieve a pre-compiled PTX string from the NVPTX backend and pass that to OpenCL's 'clCreateProgramWithBinary' function. However,

All, This year I am very interested in participating in the Google Summer of Code with a LLVM project. The main reason is that I am starting a Bachelor's Thesis about compilers that will target directly LLVM. (Note that I would like to continue beyond Bachelor) The project that me and my advisor have chosen is about compiler optimizations for GPGPU. Although I have seen some proposals for

Hi all, Has anything changed since this email that will make OpenCL support in nouveau easier? I would like to compile some information about the different steps needed to have OpenCL support for Nouveau (and the ATI open-source drivers for that matters) so that people interested in this issue can have a starting document to read. Cheers, Albert. > Kernel allows you to create the relevant

Hello, I'd like to sitch to a monochrome/bw color-palette for the filling of geom_bar-bars (produced via "qplot" as in the example below). Hours of googling didn't yield anything useful, so I thought, I'd just ask ... Thanks, Joh library(ggplot2) qplot(factor(cyl), data=mtcars, geom="bar", fill=factor(cyl))

Hi Justin, the non-translatable IR with GPU code replaced by appropriate CUDA Driver > API calls. One of CUDA driver apis (cuLaunch) need a ptx asm string as its input. So if I want to provide a one-touch solution and don't introduce any changes to tools outside polly, I must prepare the ptx string before I can generate the correct non-translatable IR part. As your suggestion, It may
