...ldly changed over time to incorporate feedback. But the latest is what is there in the RFC in discourse. RFC fails to discuss the following (I have also mentioned some of them in my reply to Johannes): > The proposed plan involves a) lowering F18 AST with OpenMP directly to a mix of OpenMP and FIR dialects. b) converting this finally to a mix of OpenMP and LLVM dialects. It is unclear in the RFC what other dialects are considered as supported for OpenMP dialect (std, affine, vector, loop, etc) and how it would be transformed, used and lowered from FIR to LLVM. It becomes important to list...

..., I summarize the current state of various efforts in clang / f18 / MLIR / LLVM regarding this. Feel free to add to the list in case I have missed something. 1. [May 2019] An OpenMPIRBuilder in LLVM was proposed for flang and clang frontends. Note that this proposal was before considering MLIR for FIR. a. llvm-dev proposal : http://lists.flang-compiler.org/pipermail/flang-dev_lists.flang-compiler.org/2019-May/000197.html b. Patches in review: https://reviews.llvm.org/D70290. This also includes the clang codegen changes. 2. [July - September 2019] OpenMP dialect for MLIR was discussed / propo...

Can someone help me understand simulations of a one-sided Cusum? Consider the following: Q[i] = max(0, Q[i-1]+z[i]), z[i] ~ N(offset, 1), with Q[0] = FIR (fast initial response). With offset < 0, mean{Q[i] for fixed i averaged over many simulations} approaches an asymptote as i -> Inf. In simulations with abs(offset) small and FIR close to the asymptote, Q[i] tends initially to drop dramatically before starting to climb again to t...

...ent/ongoing discussions about F18 being merged in LLVM. I was going through these threads, and I found few important points which were possibly left unanswered (or I might have missed few threads). URL: http://lists.llvm.org/pipermail/flang-dev/2019-December/000120.html Point: Is (3) AST -> FIR -> MLIR LLVM-IR -> LLVM-IR) in a shape where we can generate LLVM IR now? [*1] F18 generates parser tree after successful completion of parsing/semantics phase. In the above point ([*1]) AST is mentioned. Do we mean that AST and parse tree as same, as F18 does not generate anything known...

Hello everyone, I am running a mixed effects model where I have two fixed factors, one with 2 levels and one with 4, and their interaction. Let's say these are my factors and their levels: FirstFactor: 1, 2 SecondFactor: A, B, C, D For the interaction, I am interested in the four two-way comparisons, not the two four-way comparisons. In other words, I want to test whether 1A is significantly different than 2A, whether 1B is significantly different than 1B, etc; I am not interested in th...

...see it performs various kinds of correlation, but I don't see through it. At last I want to point out that at low bit-rates, like 24kBit/sec, Ogg Vorbis has trouble with "S" sounds. I thought it would be smarter to generate such sounds using a white noise generator coupled with a FIR filter, than using MDCT. Or maybe it is a problem in the encoder? What do you think? Also see: http://www.turbocat.net/~hselasky/math/image_sound/ A white noise generator is as simple as this: #define PRIME 0xffff1d /* a special prime number */ /* outputs 24-bit signed samples */ static int3...

...ple sources on the same soundcard. Unfortunately, ASIO is limited to the internal sampling frequency of the sound card, which for my Audigy 2 is 48 khz, and only delivers stereo. As I understand it, just picking every 3rd sample and averaging left and right will introduce aliasing, so I added a FIR-filter to remove all components above 7.5 khz before downsampling. While I can't say I really notice any difference in audible audio quality, the samples seem to have slightly better SNR when inspected in various audio programs. However, I still downmix to mono by just averaging the left an...

Is there a fuction that will allow me to retrun the filename for a script from within that script. fir instance If I have a script "myscript.r": FileName<-unknown.fucntion() print(FileName) and run it source("myscript.r") will return "myscript.r" Thanks Nevil Amos [[alternative HTML version deleted]]

Hi all, I would like to synchronize a part of the source file with a part of the destination file. In detail I would like to - synchronize a file on a remote host from line "n" onwards with the file content on the local host starting with line "n" in the file. - the firs "n" lines of the files on the local and remote host should not be changed. My questions are: 1) Is it possible to do this with rsync? 2) Has anyone done that before? 3) How can I do this/where can I get more information? Many thanks, Rolf This message is for the designate...
