search for: interpretor

To state my objective again because I was unclear about it. I want to write a interpretor/compiler that can handles mathematical vector/matrix with linear algebra operation on llvm. Something like matlab/R. I am thinking at a higher level like performing type, and shape inference on matrix/vector type, unrolling the inner loop of matrix operation of full algebraic expression instead of...

Hello everylinuxers: I am now focusing on the development of a script interpretor (some thing like shell) in embedded environment, and its functions mainly output the data in specified address. In order to make it seems better, I want to format the output result like MySQL output listed below for example ||+--------+-------------+ | address| value | +--------+-----------...

A user has crashed R90.1 on MS Windows by succesive calls to two of my formula/function interpretors in an order that I had not foreseen. I have checked and this also occurs with Intel RH5.2. I have distilled the problem down to its bare bones as the following set of instructions: func <- function(.mu){ .ch1 <- deparse(.mu,width=500)[-1] .fn <- eval(parse(text=paste("function()&q...

...ent the memory model where each byte is extended with 3 extra bit? (2) Is there a LLVM version of LibC (in its VM code format) currently? (3) Is LLVM able to compile HTTP servers, FTP servers and SSH servers to VM code so that every single VM instruction (include LibC code) is executed by the VM interpretor? thank you very much -Shuo On Wed, 17 Nov 2004, Vikram S.

A couple of questions please: What is the benefit of having more than one Mongrel/Rails instance on the same machine, could one instance not serve as many requests as say three instances? Is Mongrel Cluster a Apache add-in (like mod_*) or a separately running load balancer which runs on a separate port, I could not work it out from the sample Apache config... |# Redirect all non-static

...Y, Z) A <- init$A; C <- init$C; Q <- init$Q; R <- init$R rm(init) is also super cumbersome compared to Python or Julia. Another reason is of course performance, even my %=% operator written in C has a non-negligible performance cost for very tight loops, compared to a solution at the interpretor level or in a primitive function such as `=`. So my conclusion at this point is that it is just significantly easier to implement such codes in Julia, in addition to the greater performance it offers. There are obvious reasons why I am still coding in R and C, thanks to the robust API and great ec...

Can you give a more complete description of what the memory model does (or what you have to do with these three bits)? Depending on what you're doing, you might just be able to get away with writing an LLVM transformation pass. >(2) Is there a LLVM version...

...ith more than one LHS variables the assignment is an environment level operation and the results can only be used in computations once assigned to the environment, e.g. as in 1 + (c("A", "C") %=% init_matrices()), A and C are not available for the addition in this statement. The interpretor then needs to be modified to read something like nr, nc = dim(x) or [nr, nc] = dim(x). as an environment-level multiple assignment operation with no immediate value. Appears very feasible to my limited understanding, but I guess there are other things to consider still. Definitely appreciate the re...

In the approximately mathematical sense of "the sort of object manipulated by a processor with vector extensions", i.e. a generally small, fixed-size tuple of integer or floating-point element type. I don't mean the C++

Dear all, I am the author of an open-source package for mathematical optimization and automatic differentiation called CasADi (www.casadi.org) and have recently started realize the potential of the LLVM project. At the core of CasADi are two fast interpretors for mathematical expressions and I'm now planning to complement these with JIT-compilation using LLVM. Does anyone know if there is someone using LLVM for either automatic differentiation or (sparse) linear algebra (two of the things CasADi is capable of doing)? One thing particularly interes...

Hello all, Thank you very much for viewing the letter. This is Haowei (English name: Cyrus Evans) from China, who is a professiona IT editor and English interpretor. As I have gained more than 3 years' experience of localizatioin work and so much experience opensource software (including mybboard, smf etc.). As an experienced contributor, I wirte this letter to apply for joining localization work of Simplified Chinese. I hope that anyone lead this work...

Dear R Users; Perl is the common language to write CGI scripts which handle Forms. My question is that can R be as fast as perl to do the same job(with using CGIwithR package). Is it an optimal solution to connect R directly to a commercial HTML webpages, Sincerely, Sean

Hi, I have a problem with R package and bash. I have the package scatterplot3d installed and working. I'm using bash as the command line interpretor. When I open R interactively I can load scatterplot3d without problem and use it. When I create an R script it also works and execute it interactively in bash it works [xavier at coyote DIR.3thTry_1]$ cat test.R library(scatterplot3d) [xavier at coyote DIR.3thTry_1]$ R --no-save < test.R...

When you say vector in GCC, do you mean vector in the mathematical sense or the low level array sense?

Hi?all friends here. I am Nathanael Lee from China.All of you can find my ID Nathanael in our community.It's very nice for me to meet all of you here. I am an English interpretor freely worked in China.I am so lucky that in this year,I got Microsoft Community Influencer Certificate. In these 2 years,I keep my mind to focus on centos and make so many progress both in its daily use and server management. Here I just want to tell all friends here that I will start to write so...
