Hello All, By default, Astersik uses only one thread as processing jobs, Now I need to know how can it will be possible to configuring asterisk as a Multi-thread application? Do you thinks thread usage is dependent upon the O.S(Operating System) and development tools (compiler flags and libraries) used to build Asterisk or not? Any idea will be welcome. Thanks in advanced. ? Regard Sami

Thank you Johannes, I looked it up and it seems that we're creating one LLVMContext per compilation "unit", not sure if that matters. i.e. there's no single globally shared LLVMContext object. Is LLVMContext *the* concurrency isolation (or unit) here? On Wed, Apr 3, 2019 at 6:34 PM Doerfert, Johannes <jdoerfert at anl.gov> wrote: > Do you use one llvm context or one

I notice that R basic installation does not take advantage of multi-thread or multi-core processors. Is there an option for multi-threaded processors? I currently run all of my analysis on thinkpad laptop and most processing is very quick, however, when I run stepAIC with interaction terms it can take a couple of hours to complete. I have tried running the same process and a quad core machine 64

Hello, I'm happy to announce I developed a Multi-Threaded version of the Theora encoder. I changed the Motion Vector Search part of the algorithm to be executed in parallel. I've chosen the Motion search part after a careful set of profilings that shown that the Motion Vector Search is responsible by 70% of CPU-time on average and up to 95% of CPU-time in some cases. I also have chosen

When a highly multi-threaded program such as nbdcopy encounters an error, there is a race condition in the library which can cause an assertion failure and thus a core dump: (1) An error occurs on one of the threads. nbdcopy calls exit(3). (2) In lib/errors.c, the destructor calls pthread_key_delete. (3) Another thread which is still running also encounters an error, and inside libnbd the

It seems relevant to point out there have been several efforts over the years to solve this problem by eliminating the static initializers in LLVM and migrate cl::opts to storing their values in a context object. One of those efforts was made by me back in 2014 (see https://reviews.llvm.org/D6207 <https://reviews.llvm.org/D6207>). One of the perennial problems with cl::opt is that many of

Hi, I'm looking for the most efficient OpenSource IMAP server and I am told that Dovecot Server is a good solution. Anyway, I have inspected the source code and I think Dovecot is not a multi-threaded server, but a forked server. I am surprised about this issue, because threads perfomance should be higher than creating a new process for each connection....I suppose. So, Could anybody tell

Hi llvm-dev, Our code base has a ancient copy of llvm (ver 3.5.1), and it uses the LLVM code gen for some domain-specific language. The previous dev left a global lock around the usage of LLVM code gen stating that because LLVM code gen can only be accessed single-threaded it needs to be protected with this global lock. But now this lock has caused some perf issues as we pretty much lose

Hi Ghislain, I think you might be comparing two versions of R with different BLAS implementations, one that is single threaded (is your 3.3.2 used with reference blas?) and one that is multi threaded (3.4.1 with openblas). Could you check with "perf"? E.g. run your benchmark with "perf record" in both cases and you should see the names of the hot BLAS functions and this

Hi Ghislain, The documentation at https://cran.r-project.org/doc/manuals/r-release/R-admin.html#BLAS provides a fair bit of information. What specifically would you like to see added?

Hi, I have a system in which rysnc is being used at multiple times. Since a last 3-4 months we have been observing a crash in rysnc at few instances. I am not able to find out the solution for the same but while debugging the issue in code I found gmtime() being used in "tls.c". It is not suggested to use this function in a multi-threaded environment. Version: rsync 2.6.2

Hi All: I am building the torture/smbtorture for samba-4.0.0alpha17. After build, I am running the test in another environment. I not only need to copy the binary smbtorture, I also need to copy the shared libraries. This is HUGE inconvenient for us. Could somebody tell me how to build the binary using static linked libraries? Thanks very much Peixing libpthread.so.0 =>

Hi Ista, Maybe a little comment in the 'matmult {base}' doc page or on the 'options {base}' in the field 'matprod' would be useful to remind users to be cautious regarding BLAS multi-threading? I understand why this is a BLAS related issue and not directly an R related issue. Nonetheless, my concern was for non-advanced R users, that may don't even know what BLAS

Hi all, I've compiled R (version 2.8.1) from the source code with "--with- blas=" option in order to use external multi-threaded blas package. However, it's very hard to verify that compilation is correct and R is using multi-threads correctly or not. Which command or operation in R will run with multi-threads? I assumed that matrix multiplication %*% may call multi-threaded

On multiple core systems OpenSSH is limited to using a single core for all operations. On these systems this can result in a transfer being processor bound even though additional CPU resources exist. In order to open up this bottleneck we've developed a multi-threaded version of the AES-CTR cipher. Unlike CBC mode, since there is no dependency between cipher blocks in CTR mode we

Hi, I would like to extend LLVM IR with two new intrinsic: spawn and join. The spawn intrinsic will indicate that the call it modifies can safely run in parallel, while join intrinsic will indicate that the execution of the current call cannot continue until all previously spawned calls in the list/array passed as argument to join intrinsic have completed and returned their results to it.
