[OMPI users] Add/remove "Event Listeners" in MPI?
What I want to achieve is something like: - root process listens to children process - children will listen to root for stop notification - children starts doing work - when 1st child completes, notify root - root then notifies all processes to stop How can I implement something like this in (Open)MPI/C++? Listen will be something similar to IRecv? But how do I cancel those IRecv later?
[OMPI users] MPI_Recv MPI_THREAD_MULTIPLE
I have a problem here.
My program runs perfectly in MPI version 1.6 series, but it would run into some
problem in MPI version 1.4x series. Does MPI 1.4x version have a bug related in
MPI_Recv.
The log in Node[1] says that "MPI_Recv in node[1] can not probe tag [11] from
source[0]". But in node [0], the log says it Isend message with Tag [11] to
dest [1].
int provided;
MPI_Init_thread(&argc,&argv, MPI_THREAD_MULTIPLE,&provided);if(provided !=
MPI_THREAD_MULTIPLE){
printf("Sorry, your MPI library does not provide MPI_THREAD_MULTIPLE\n");
MPI_Abort(MPI_COMM_WORLD,0);}
Both of my 1.6x and 1.4x library do not support MPI_THREAD_MULTIPLE. Is this
the reason? But why it runs perfect with 1.6x version.
Thanks very much for your help.

[OMPI users] What is the default install library for PATH and LD_LIBRARY_PATH
Hell all, I installed OpenMPI on my Ubuntu 64 bit desktop. At first, I did not specify "prefix", so even I've installed it. I could not find where it is. Since the "PATH" and "LD" have to be given, the mpicc can find the "lib open-pal.so.0" file. Thanks very much. Paul

If you use the default location, it should have the correct settings already even without adding any path to PATH or LD_LIBRARY_PATH. You can use: $ find /lib -name "libopen-pal.so.0" to spot the location. But I wonder about the version. The actual one seems to be libopen-pal.so.4 -> libopen-pal.so.4.0.3 - which version are you using? -- Reuti
Re: [OMPI users] What is the default install library for PATH and LD_LIBRARY_PATH
Hi Reuti, Thanks for your answer. I really appreciate it. I am using an old version 1.4.3. for my code. If I only type $./configure, it will compile, but I have no idea where it is installed. I typed $ find /lib -name "libopen-pal.so.0", but it shows nothing. Do you thinks it is caused since I am not a root user or the old version.

If you are not the root user, you will likely prefer to install it in your own home directory with options like: $ ./configure --prefix=$HOME/local/openmpi-1.4.3 $ make $ make install Any reason not to use the latest version? -- Reuti > , but I have no idea where it is installed.

Re: [OMPI users] What is the default install library for PATH and LD_LIBRARY_PATH
./configure does not compile, but generates the Makefile. Did you run > make > make install after running ./configure? Notice also that openmpi can very likely be already installed on your system from ubuntu packages; anyway, I suggest you use ubuntu packages rather than compiling from sources unless you have a very good reason not to use the packaged version. you can also quite safely re-run make install to see where the libraries are going to.

Re: [OMPI users] What is the default install library for PATH and LD_LIBRARY_PATH
Koza, Thanks a lot for your help. It is indeed installed already.
