similar to: Bigalgebra and irlba error

Hello, good mornig, i have one questions, anybody know how to calculate svd of a matrix of the library bigmatrix with library irlba? thanks [[alternative HTML version deleted]]

According to comment in tree-nested.c, these frames should be only introduced in case of debug or OpenMP lowering: /* A subroutine of convert_nonlocal_reference_op. Create a local variable in the nested function with DECL_VALUE_EXPR set to reference the true variable in the parent function. This is used both for debug info and in OpenMP lowering. */ However, in this code example we

Hi Duncan, A DragonEgg/GCC-related question: do you know where these strange FRAME tokens originate from (e.g. %struct.FRAME.matmul)? Compiling simple Fortran code with DragonEgg: > cat matmul.f90 subroutine matmul(nx, ny, nz) implicit none integer :: nx, ny, nz real, dimension(nx, ny) :: A real, dimension(ny, nz) :: B real, dimension(nx, nz) :: C integer :: i, j, k real,

Hi, Using the example in ?VSEM in the package BayesianTools I'm attempting to iteratively update the prior but find the plotTimeSeriesResults produces the following errors when I extend the VSEM example in BayesianTools. With the Code below (the errors) I get: " Error in quantile.default(x, probs = quantiles[i]) : missing values and NaN's not allowed if 'na.rm' is

Hi everyone, I'll be very thankful if anyone can help me. I want to extract the dependences details by using polly. I followed the following steps on example code matmul.c: 1. clang -S -emit-llvm matmul.c -o matmul.s 2. opt -S -polly-canonicalize matmul.s > matmul.preopt.ll 3. opt -basicaa -polly-dependences -analyze matmul.preopt.ll But it doesn't show me the dependences. I

Dear All, I've had trouble compiling DPpackage as a user in one system. It works fine as root in other machines. I can see any clues in error messages My guess is that it is a permissions matter. Any help is appreciated. OS: Linux Kernel: 2.6.27 SMP Arch: Intel 64 bits gfortran not available Thank you. ----------------------><8------------------------------------- g77 ? -fpic ?-g

Hi, When I test "matmul" in the polly directory, I get the following performance data: //=============================== --> 12.

What version of LLVM are you using? The profiling framework is completely messed up in the newer versions of LLVM.. I used to work with profiling in 2.5 some time ago, and it seemed to work fine.. If you really need this to work quickly, you might want to just get the old version and get on with it.. The newer versions of LLVM need to get the profiling part fixed soon..It is messing up my work as

Dear all, I have already checked some related posted messages, such as: http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-January/012315.html and http://lists.cs.uiuc.edu/pipermail/llvmdev/2008-February/012466.html After getting rid of some error messages, I was able to run the following commands: 1) opt -insert-path-profiling matmul.bc -o matmul.pp.bc 2) lli -load

Hi, I have a problem - looking for advice. I have a source code file with two functions which are compiled into a .bc file. When the bitcode file is loaded, I can dump the module and see the two functions: ... ; Materializable ; Function Attrs: noinline nounwind uwtable define void @matmul(double*, double*, double*, i32, i32, i32) #0 {} ; Materializable ; Function Attrs: noinline nounwind

I am writing a function in fortran 95, but the intrinsic function MATMUL is not working properly. Here's an example. SUBROUTINE mymult(x,y,res,m,n) IMPLICIT NONE INTEGER :: m,n REAL :: x, y, res DIMENSION :: x(m,n), y(n,m), res(m,m) res = MATMUL(x,y) END SUBROUTINE mymult R CMD SHLIB mat.f95 In R: dyn.load("mat.so") x <-

I just checkout release_38 branches of llvm, clang and polly and built it on and x86 Ubuntu with cmake: CMAKE_BUILD_TYPE="Debug" CMAKE_INSTALL_PREFIX="$HOME/toolchain/install/llvm-3.8" LLVM_TARGETS_TO_BUILD="X86" cmake -G "Unix Makefiles" \ -DBUILD_SHARED_LIBS="ON" \ -DCMAKE_BUILD_TYPE=$CMAKE_BUILD_TYPE \

Hi Tobias, I tried to invoke other passes and none of them are available, e.g.: ~/toolchain/install/llvm-3.8/bin/opt -load ~/toolchain/install/llvm-3.8/lib/libPolly.so -polly-cleanup opt: Unknown command line argument '-polly-cleanup'. Try: '/home/fwinter/toolchain/install/llvm-3.8/bin/opt -help' opt: Did you mean '-polly-tiling'? I am just shooting around hoping to

Dear R-devel readers: I am really stuck trying resolving an issue with the use of the Matrix in one of my packages, irlba, with R-2.14.0. When I use crossprod with at least one sparse argument in the packaged code I receive the error: Error in crossprod(x, y) : requires numeric/complex matrix/vector arguments However, when I run the code outside of the context of the package it works fine.

This is kind of like asking for a solution to x+1=x+1. Go back to linear algebra and look up Singular Value Decomposition, and decide if you really want to proceed. See also ?svd and package irlba. -- Sent from my phone. Please excuse my brevity.

The long-promised revision to bigmemory has arrived, with package 4.2.3 now on CRAN. The mutexes (locks) have been extracted and will be available through package synchronicity (on R-Forge, soon to appear on CRAN). Initial versions of packages biganalytics and bigtabulate are on CRAN, and new versions which resolve the warnings and have streamlined CRAN-friendly configurations will appear

Hello. I tried to get the trip count of a loop with Scalar evolution. I got inspired from http://stackoverflow.com/questions/13834364/how-to-get-loop-bounds-in-llvm . However the analysis described there doesn't work well for the second inner loop of thes function below (although if we declare Bcols a short it works well): void MatMul(int Arows, int Acols, int Brows, int

Dear Sir/Madam, I have a large data set of 10,17,289 observations of 10,830 variables. I need to use PCA to reduce the dimension of dataset. I have already tried irlba, prcomp and nsprcomp packages in R but couldn't do for huge data sets. i.e pc <- prcomp_irlba(sparseYY[1:5000,], n=50, retx = TRUE, center = TRUE, scale. = FALSE) able to get only few PCs for 5000 rows only so can you

Hi, I am trying to use GDB for debugging my llvm pass. I am following the documentation http://llvm.org/docs/WritingAnLLVMPass.html. When i am doing this the following error and warning messages I am getting. I tried to remove the warning by apt-get install libc6-dbg:i386 command for updating the libc6 but still getting the same.
