Dear, I looked in the list something on as to compile a code with access the High Performance FORTRAN using R CMD SHLIB, but I did not find. Would like to know if the accepted R this type of language? Thanks! ? ????????????

...recommend you to transform everything to LLVM IR and do your stuff there. The LLVM IR is more high level and extremely more expressive (types and everything) than GCC IR, so you probably get everything you want from there. > Longer term, it sure would be nice to have flang.  :) That supports HPF!!

...should be done at a higher level. > It _can_ be done at the LLVM IR level, but much less conveniently. Now I agree with you, completely. ;) It is important, it is the future, but it is in the library/language definition space that the solution will be more elegant. Like functional languages, HPF, openMPI, Scala having intrinsic message passing or openMP constructs, the compiler has much more freedom to guess and do the right thing (tm). cheers, --renato http://systemcall.org/ Reclaim your digital rights, eliminate DRM, learn more at http://www.defectivebydesign.org/what_is_drm

...ototype” for a language like OpenMP because you can’t exclude REDUCTION clauses. Fourth, I believe array privatization is even harder; more generally, you cannot rely on heroic compiler optimizations to take the place of explicit language directives. I may be showing my age, but I co-wrote a full HPF-to-MPI source-to-source compiler in the late 1990s at Rice University with some quite sophisticated optimizations [1,2], and we and others in the HPF compiler community — both product and research teams — encountered many cases where compiler analyses were inadequate. There is a credible view that...

Concurrent languages can help, but history shows that it's tough to get them accepted. HPF is a four-letter word here. ;) Now CAF, on the other hand... Maybe this trend will change with the new silicon constraints, but I'm skeptical. We'll be programming in C, C++ and Fortran for a long time.

Hi all, I want to compile FORTRAN 95 code with LLVM. More specifically, I would like to get an AST dump of the program I compile, statically analyze the AST, make modifcations to the AST and then feed it back to LLVM. Do you have any hints as to how I should proceed about doing this. I noticed that clang has an ast-dump option but don't know whether it supports FORTRAN 95. I am a LLVM newbie

Could someone, please, write me, how to compute the spar-value for the smooth.spline-routine to get the same HP-filtered time-series with a parameter lambda for a function (see mail "Hodrick-Prescott-Filter example" from ggrothendieck at yifan.net): hpf <- function(y,lambda{ eye <- diag(length(y)) d <- diff(eye,d=2) z <- solve(eye+lambda*crossprod(d),y)} ? Second, is there a connection between the parameter lambda in this function and the value $lambda of the smooth.spline routine? For annual time series with smooth.spline(y,spar=...

...his opens the door to new applications of computers, in turn requiring even more data to be managed and controlled. Are the concepts of today's array processing languages able to meet these challenges? Many programming languages and symbolic interpreters, including APL, R, S-Plus, Fortran 95, HPF, J, MATLAB, MAPLE, NIAL, SAC are becoming stronger array processing languages. What features do these languages have in common? How do they differ? Are they converging in terms of primitives, parallelism, functionality, data and control flow, interfaces to hardware and software, and in communicati...

Dear All, The institute I work for is organizing an internal workshop for High Performance Computing (HPC). I am planning to attend it and talk a bit about fluid dynamics, but there is also quite a lot of interest devoted to data post-processing and management of huge data sets. A lot of people are interested in image processing/pattern recognition and statistic applied to geography/ecology, but I
