On Windows there are a few 'pthreads' implementation, e.g. pthreads-w32 and winpthreads [https://cran.r-project.org/doc/manuals/r-devel/R-exts.html#Using-pthreads]. We're thinking of giving them a try for the matrixStats package, and basic tests indicates it works, but since Windows pthreads are not used by core R (or?) I've got a little bit worried that we will face overwhelming

Hi, While searching for a project which matches my interest andskill level, I found this project named Matcher Optimization. This project is really challenging and excting from my view point and I would like to be a part of this project. Optimization techniques metioned in the reference links provided will take some time for me to have a good understanding about them. But I am trying to get my

Hi, [This is a follow-up to the "New version of Rtools for Windows" thread in January, but I just subscribed and don't know how to reply to an old thread -- my apologies.] I was able to use the nuwen distro to build a gcc 4.9.2 toolchain and use it to build the latest R-patched with it. Below are some notes about what I did; I hope they will be useful for keeping Rtools

Aaaah ... and argh - I should have better not to post R question at midnight, especially when I know it forks the process and it's not using threads. Brain meltdown. (So, we'll proceed trying to use pthreads in matrixStats also for Windows). Sorry for the noise and thanks Kasper.

Dear All I really need your help in this issue. Now, I am working on analyzing LLVM test-suite.I have some questions about it. The question is: Whether you have detail infomation on what each subdirectory of test-suite test. Thank you !

Dear R experts, Greetings from China! I'm Zhang in the College of Education, Zhejiang University, and I am recently running a meta-analysis. Since research using the randomized controlled trial (RCT) often dismissed reporting the correlation (r) between multivariate outcomes, for instance, a study measuring students' gains on problem solving skills with three aspects and reported the

Hello, guys. Q1. now I have load all the docid and its document data into a dictionary for faster loading data instead of calling Xapian::MSetIterator i; i.get_document().get_data(); but I was happened to discover that the dictionaries got by such two method were different: both methods use DB1, DB2 method 1: Xapian::Database db = Xapian::Database(the path of DB1); Xapian::Database db2 =

Hi, I am Jiarong Wei (irc: VcamX). I?m a 3rd year computer science student at Zhejiang University, China. I?m very willing to contribute to Xapian as part of GSoC 2014. Now I?m at Simon Fraser University, Canada, as an exchange student. I?ll go back to China on the end of April. I think it doesn?t matter I?ll change the time zone :) From the list of project?s ideas, Learning to Rank interests me

Hi all, The 3rd HelloLLVM social in China will happen on July 28, 2018. The location is at Hangzhou, Zhejiang. Everyone interested in LLVM related projects is invited to join.

I hadn't noticed any interactive slowdown, but when I got around to running the notmuch performance suite, there seems to be some noticable slowdown with the glass backend (default in Xapian 1.3.5) compared to chert (using xapian 1.2.22) These tests are on an older i7 with 12G of RAM and an SSD. I'm reasonable confident they are CPU bound. One curious thing is the increase in system time

Hi, I intend to participate in Google's Summer of Code this year, so I'd like to bounce another idea around to see what you guys think. (I posted a similar message to cfe-dev just now.) Be warned: this will shock you. It may even horrify you. 1. Implement a 16-bit x86 backend. (*Chris recoils in horror*) Yeah, I know 16-bit x86 is dead, but I find it interesting for historical purposes

Well, is that possible to include libstdc++4.7 into llvm?

The width and height can be runtime values that we would just copy into 64 byte configuration block we pass to ldtilecfg. So the code doesn't need to be multiversioned. The user code would also use those values to update pointers in the loops they write using the tiles. If we can't determine that two tiles were defined with the same width and height we need to assume the shape is different

There is no problem to have 256 register classes. Just a lot of register classes to me. We don't assume the shape of each physical register be 16x16, it is defined by user. For variable shape, I mean the shape is known in runtime and in compile time the shape is unknown. Take below code as an example, the %row and %col are variable instead of constant.
