similar to: Pre-compilation and server-side parallel execution

Hi All, My problem is about parallel execution of R-scripts. My platform is linux. A program that is written in C needs to execute multiple R-scripts simultaneously. The C program makes use of multi-threading. Each thread must initiate the execution of one script. Performance is very important. Appearantly the R C-API does not provide a mechanism for parallel execution.. It is preferred

We can use now ImageioClient to communicate with ovirt-imageio server on oVirt host. Using the client greatly simplifies the plugin, and enables new features like transparent proxy support. The client will use transfer_url if possible, or fall back to proxy_url. Since the client implements the buffer protocol, move to version 2 of the API for more efficient pread(). Another advantage the client

Hi, When trying to connect my USB printer to the DomU that has CUPS installed, I run into an error: Unexpected error: <class ''xen.util.vusb_util.UsbDeviceParseError''> Please report to xen-devel@lists.xensource.com Traceback (most recent call last): File "/usr/lib/xen-4.0/bin/xm", line 8, in <module> main.main(sys.argv) File

Q: I wasn't sure if we still need the "UnsupportedError" class so I left it in. Q: Does the Unix socket always have the same name? What happens if there's more than one transfer happening? I tested this both ways, and it worked both

Hi, in "save.image", it would be nice if there was a "compression_level" argument that is passed along to "save". Or is there a reason for disabling the "compression_level" option for saving workspaces, but enabling it for manually saving individual objects? Thanks, Andreas

Hi there, I just wanted to take a quick second to thank everyone who maintains this service- just in case you don't hear it enough, there are a plethora of people who rely on this service (as evidenced by the help archives), and even if they don't say it, are greatly thankful for what you do here. Not only are you providing a service to people who are learning R, but indeed helping

Hi all please can any one help me to find the reason?? i am using LLVM to execute two programs both of them was exactly similar but the difference was the first one is a sequential program has three functions. In the second program i am trying to execute it by giving each function to thread (three thread work in parallel way) ,but when i am trying to calculate the execution time i found

Otherwise you are going to have to send in your programs along with an explanation of how you compiled them exactly (exact sequence of commands) both for gcc and LLVM. Ciao, Duncan.

Dear all, I have a piece of code that  I want to run in parallel (I am working in system of 16 cores) foreach (i=(seq(-93,-73,length.out=21))) %dopar%  {           threshold<-i            print(i)          do_analysis1(i,path)          do_analysis2(i,path)            do_something_else_analysis1(i,path)            something_else_now(i,path)  } as you can see I have already tried to make

[...] For a certain definition of "easy" :-) Our QE team tests -o rhv-upload from time to time, and will do an end-to-end test of the system when RHV 4.4 arrives with the new feature. For “make check” we need

Dear R helpers, I have what another member on this forum described as an embarrassingly parallel problem. I am trying to fit models on subsets of some data based on unique combinations of two id factors in the dataset. Total number of combinations is 30^5, and this takes a long time. So, I would like fit models for each of the datasets produced by subsetting on the unique combinations, splitting
