where is libmpifort.so?

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: libmpifort.so.12: 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?

Thanks.

Intel ITAC error

Hello,

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. 

Does n550 cpu support parallel programming(mpi)?

Hello everyone,

i have samsung n150 plus netbook. it has intel n550 cpu. i want to develop some mpi programs with this device but i can't install MPICH libraries or any others. When i tried, i get warning like this.

'This installation package is not supported by this processor type. Contact the product vendor.'

 

But when i searched, learned that n550 has 2 cores. What is the problem, i can't solve it. Is there any program(or supporting thing) for this processor (n550), using for parallel programming?

  • Profiling a complex MPI Application : CESM (Community Earth System Model)

    Hello. 

    CESM is a complex MPI climate model which is a highly parallel application. 

    I am looking for ways to profile CESM runs. The default profiler provides profiling data for only a few routines. I have tried using external profilers like TAU, HPC Toolkit, Allinea Map, ITAC Traceanalyzer and VTune. 

    As I was running CESM across a cluster (with 8 nodes - 16 processors each), it was most beneficial to use HPC Toolkit and Allinea Map for profiling. However, I am keen on finding two metrics for each CESM routine executed.  These are :
