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

Greetings,​

 

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 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?
