Re: [hwloc-users] HWLOC problem

(brought over from the OMPI user's list) This likely means you installed hwloc to a non-standard location (meaning that your system is not looking for shared libraries in $hwloc_prefix/lib by default). If you prepend/append your LD_LIBRARY_PATH environment variable (or set it, if it's not

This should be addressed on the hwloc-users list; I'll reply over there. On Jun 7, 2011, at 12:51 PM, vaibhav dutt wrote: > Hi, > > I have installed HWLOC 1.2 on my cluster , each node has two Intel Xeon E5450 > quad cores. > When I try to execute the command "lstopo" to determine the

[OMPI users] HWLOC problem

Hi, I have installed HWLOC 1.2 on my cluster , each node has two Intel Xeon E5450 quad cores. When I try to execute the command "lstopo" to determine the hardware topology of my system, I get an error like: ./lstopo: error while loading shared libraries: libhwloc.so.3: cannot open shared object

[OMPI users] Building OpenMPI v. 1.4.3 in VS2008

Hello, I'm currently trying to build OpenMPI v. 1.4.3 from source, in VS2008. Platform is Win7, SP1 installed ( I realize that this is possibly not an ideal approach as v. 1.5.3 has installers for Windows binaries. However for compatibility with other programs I need to use v. 1.4.3 if at

Re: [OMPI users] Problem with MPI_Intercomm_create

George, I did not look over all the details of your test, but it looks to me like you are violating one of the requirements of intercomm_create namely the request that the two groups have to be disjoint. In your case the parent process(es) are part of both local intra-communicators, isn't it? I

Re: [OMPI users] ifort 12.0.4 install problem

Thanks for your reply In fact as you said it was a strange problem with the .bashrc with sudo make install I have the error, but with sudo bash and then make install the error disappears. I did'nt understand why Everything seems OK now, no more problem at runtime. Thanks 2011/6/7 Jeff

Re: [OMPI users] Problem with MPI_Intercomm_create

Frederic, Attached you will find an example that is supposed to work. The main difference with your code is on T3, T4 where you have inversed the local and remote comm. As depicted on the picture attached below, during the 3th step you will create the intercomm between ab and c (no overlap)
