Intel MPI and Windows firewall on localhost

Hi everybody,

We run mpiexec on Windows 7 on multiple network installations of our product in the following manner:

mpiexec.hydra.exe -np x -localroot -delegate -localonly -localhost one_path_to_EXECUTABLE

The problem is with the windows firewall (which is executable path triggering) and alerts, because mpiexec.hydra.exe and pmi_proxy.exe do a listen on

Is there an option / environment variable available to tell mpiexec.hydra only listen on instead of all available interfaces if we run it only local on one workstation.

open_hca: getaddr_netdev ERROR: Connection refused. Is ib0 configured ERROR

Dear all,

I am a beginner in linux; i am using quantum espresso software; The cluster we have at University has three types of partition short (for jobs within an hour), long (jobs within 4 days) and superlong (jobs within 10 days). each node has 8 processors; however recently when I am running a job, only the SHORT partition works properly; this is not very useful for me as I need to run longer jobs. when i run the other two (long and superlong) I get several errors: running on more than one node say : 16 processors (2 nodes) producesan error:

Intel MPI Benchmarks Archives

I wish to use Intel MPI benchmarks for performance analysis of my mpich2 implementation. However, I'm using mpich2-1.4.1 version in my cluster. Where can I download the appropriate benchmarks for this version of mpich2? The latest version is not compatible with the mpich2 version I use.

Please help.

Intel® Parallel Studio XE Cluster Edition for Linux



I am planning to develop some code for my client, to be executed on a 3 node cluster to start. Would I require this software to be installed in each of the nodes?


My client is in the progress to procure licences for this software. However this may take a while. Will it be possible to extend the evaluation period a while longer?


Thank you.




where is

HI, Everyone,

Today, when I run my hybrid MPI/OPenMP application with MPIRUN on our 3-nodes Infinband Linux-PCs Cluster, the following error occurred:

/cmg/dingjun/imexLocal/imex_xsamg_dave.exe: error while loading shared libraries: cannot open shared object file: No such file or directory

Could you tell me how to fix it? I look forward to hearing from you.

Thanks in advance.


MPI equivalent of KMP_PLACE_THREADS on MIC

Hello All,

When I run pure OpenMP example on MIC, I find KMP_PLACE_THREADS very useful. (for example, I can benchmark using 8 cores and 3 threads on every core with "KMP_PLACE_THREADS=8c,3t,0O"

What is MPI equivalent for this? (I am running pure mpi application natively on MIC with Intel MPI) 

In the documentation I see I_MPI_PIN_PROCESSOR_LIST where I can provide the list of specific processors. Is there any other way?


Intel ITAC error


I am using Intel Traceanalyzer to profile an application called CESM. Since I want to profile the user defined functions, I instrument the code using the -tcollect option during compilation. This happens successfully. 

After compilation, I use the -trace option in the mpirun command. 

After the run is completed, I see that the several trace files are generated. 

When I open the $application.stf file (the appropriate stf file), I get the following error in the Intel Traceanalyzer.
