Dear list, is R capable of multithreading? At the moment it uses only 1 CPU out of 4 CPUs on my system. Is there a compilation option or start option so that R uses multiple CPUs at the same time to accomplish a calculation? Some information on my system: > R.version _ platform x86_64-pc-linux-gnu arch x86_64 os linux-gnu system x86_64,

Hi all, I was looking at the profile for a tool I’m working on, and noticed that it is spending 10% of its time doing locking related stuff. The structure of the tool is that it reading in a ton of stuff (e.g. one moderate example I’m working with is 40M of input) into MLIR, then uses its multithreaded pass manager to do transformations. As it happens, the structure of this is that the parsing

Multiple questions here, thinking one email is less annoying (sorry if not). Running tinc 1.0.31 1. Could anyone give an explanation (or point to documentation) of the differences between Connections, Nodes, and Edges in the USR1/2 logging, and the various information in there? 2. Connections appears to match the list of ConnectTo hosts in the main config file -- does this mean this node can

I was surprised, given the vector-ish nature of R, to see that (according to my CPU meters) there doesn't seem to be any obvious multithreading in R. Are there any plans to change this?

Hi All, I have looked through the following thread: http://tolstoy.newcastle.edu.au/R/help/02b/4551.html and would like to ask after 1.5 year the same question: Are there any plans to involve multithread computations in R? Few word about my motivation: I use R on my OpenSSI cluster with 7 CPUs, so one could simply think of this cluster as of single computer with 7 CPU. My

Hi. We have a configuration and audit application called Tripwire Enterprise (7.5) that is running on a Red Enterprise Linux 5.2 server. On this server, we are using winbind (samba version 3.0.33) for authentication (against Windows AD). When we try to run a configuration check on users and permissions we get an error that there is a problematic frame : C [libnss_winbind.so.2+0x129f] . I

Hey FLAC devs, I managed to hack out a proof-of-concept multithreaded FLAC encoder based on the example libFLAC one. It turned out to be fairly straightforward to get near-linear speedup; I can encode a 636 MB wave file in 6.8s with 8 threads on an 8-core 3.0 GHz Xeon vs. 31.4s with a single thread. Basically I mmap() the input file, divide up the mmap()ed region into nearly equal pieces,

Hi. I need to execute a function from within a GUI. This seems to be no problem but this function takes about 4 minutes to finish, which means the application doesn't react at all, while the function is running. Can I execute a function as a separate Thread, while keeping control(e.g. a reference) of it at the same time? If not, how do this with a class containing this function? thanks,

Hi Richard! Maybe the function guestfs_mount_local_run shouldn't ACQUIRE_LOCK_FOR_CURRENT_SCOPE as it doesn't talk with the daemon and sits in the loop? What do you think? If I remove it from guestfs_mount_local_run (in lib/action-1.c, don't know how to properly remove it from ml generator), fuse_loop_mt works, but I still don't understand how it worked with fuse_loop (single

Hi all: I am working on a project using llvm and we need to deal with multithreaded applications. I wanted to know if there was a C front end for llvm that could parse multithreaded applications? I tried llvm-gcc (4.2) and could not get it to work. Is there an extra parameter that I need to pass or something ? Thanks a lot for your help. Regards -- -- Aparna Graduate Student Department

Hi; I am porting my POSIX multithreaded application from SOLARIS to RHEL. My application uses Sun RPC(with Automatic multithreading option). In RHEL RPC I could not find any option for Automatic multithreading. Please help me. Regards, Lingu -------------- next part -------------- An HTML attachment was scrubbed... URL:

I am interested in being able to encode a single Opus stream using several CPU cores. I get a raw audio input and "opusenc" can transcode it at 1200% speed (Raspberry PI 3B+). It saturates a single CPU core, but the other three are idle. Is out there any project to add multithreading options to "opusenc", or something in that line? Looking around, I have found this:

However, if you limit yourself for the moment to loops that fit into the polyhedral model, you can take

Hello, To connect to our oracle database from an asterisk application we use res_perl. Sometimes one of our asterisk server will 'freeze' and work anymore. I have to kill the job safe_asterisk and start it again, so that the application asterisk works again. If I look in the log files it look like that asterisk will 'hang or freeze', if two callers calls exactly at the
