similar to: [LLVMdev] [Polly] Parallelizing outer loop containing inner reduction loop

Dear all, Yesterday, from the customer's code I observed relatively simple case, where Polly is unable to detect parallelizable outer loop. Consider two versions of Fortran routine: 1) subroutine filter(H, szh, X, szx, Y, szy) implicit none integer(kind=IKIND), intent(in) :: szh, szx, szy real(kind=RKIND), intent(in) :: H(szh), X(szx) real(kind=RKIND), intent(out) :: Y(szy)

Hi Tobi, Thanks for looking into this! 2013/2/4 Tobias Grosser <tobias at grosser.es> > > In any case, you seemed to have in some way convinced Polly to accept this > code.

Instead we have substituted pointers and sizes for arrays and a special pass that converts memory accesses from every scop statement

Hi there Looking at the archives I didn't find a solution to the following problem we have here: Printing from our linux-server (wagner) to an intel printserver (PS652D8F) doesn't work. Here's the stuff we know/tried: wagner:~ # smbclient -L //PS652D8F -N added interface ip=10.0.0.10 bcast=10.0.0.255 nmask=255.255.255.0 Got a positive name query response from 10.0.0.40 ( 10.0.0.40

can anybody guide me on how to create inner joins and left and right outer joins in RoR as both the tables has "has and belongs to many relationships" and there is ajoin table as well

Hi I am trying to get Battlefield 2 and Battlefield 2142 to launch under Kubuntu 10.04 & Wine 1.3.6. I'm using an Nvidia 8800 GTX 768Mb GPU with Nvidia blob driver 260.19.12. Anyway launching BF2142 (retail copy, patched to v1.5) gives me the following error (2x) in the console output streams: Code: ... err:x11settings:X11DRV_ChangeDisplaySettingsEx No matching mode found 800x600x32

Hello! I have a program in Fortran and would like to build a matrix with random numbers, I have a function in C. However, I have problems with the use of function in R. Code to compile: R CMD SHLIB mat.f myrbeta.c -o func.so Code in C. #include <R.h> #include <Rmath.h> void F77_SUB(fseedi)(void){   GetRNGstate(); } void F77_SUB(fseedo)(void){   PutRNGstate(); } void

Hello, I am having trouble specifying a suitable nlme model. My data structure is described by gd <- groupedData(ppath ~ lcut | exp, outer = ~ bait, inner = ~ weight, data = d) i.e. the response (ppath) of several subjects (sub) was measured at levels of a continuous variable (lcut). Subjects were given either of one level of a factor (bait), and all subjects were measured at two levels

Hi, I'm using R 7.0 under Linux as a programming interface to Fortran (g77 v0.5.24). Basically, what I want to do is to call a fortran subroutine of mine which performs MCMC computations. Apparently I'm getting into memory management problems. To track the problem I wrote the following small Fortran subroutine (saved as test.f) : subroutine test(n,p) implicit none

Dear John You are only allowed to have the primary covariate on the left hand side of the vertical bar. Other covariates go in inner or outer.

Windows 10 64-bit, R-Studio, R version 3.4.3 Several questions relating to groupedData: (1) I am trying to create a groupedData object that can be used to run an analysis that I have been able to urn using lmer. When I include the interaction terms in the groupedData opbject I get an error message stating that + is not meaningful for factors. How do I include factors in my model? See code and

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

Hello, I'm finding problems with BackEdgeTaken count calculation in even simple fortran loops with gfortran-4.6 + DragonEgg 3.0.

Your patch should include a testcase, see test/Analysis/ScalarEvolution for examples. "BranchInst* " should be "BranchInst *". You should have spaces after the // in your comments. One of the comment lines isn't indented properly. Nick On 8 February 2012 12:05, Marcello Maggioni <hayarms at gmail.com> wrote: > Attached > > 2012/2/8 Marcello Maggioni

Hi, I've read up on readBin() and chapter 6 in the R Data Import/Export manual, but I still can't read a binary file. Here is how the creator of the file described the code that would be needed in Fortran: "Every record has a return in fortran. The length of each record is nx*ny*4. To read you would use the following: nlayx = nx*ny*4 do iz=1,nz,4 read(binary file) var(1:nlayx)
