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 :

Performance issues of Intel MPI 5.0.2.044 on Windows 7 SP 1 with 2x18 cores cpus.

Dear support team,

I have a question about a performance difference between Windows 7 SP 1 and RHEL 6.5.

The situation is as follows:
The hardware is a DELL precision rack 7910, see link for exact specification (click on components):

Hi, Everyone,

I am running my hybrid MPI/OpenMP jobs on 3-nodes Infiniband PCs Linux cluster. each node has one MPI process that has 15 OpenMP threads. This means my job runs with 3 MPI processes and each MPI process has 15 threads.

the hosts.txt file is given as follows:

coflowrhc4-5:1
coflowrhc4-6:1
coflowrhc4-7:1

 I wrote the following batch file as follows:

Intel MPI 5.0.3.048 and I_MPI_EXTRA_FILESYSTEM: How to tell it's on?

All,

I hope the Intel MPI experts here can help me out. Intel MPI 5.0.3.048 was recently installed on our cluster, a cluster that uses a GPFS filesystem. Looking at the release notes I saw that "I_MPI_EXTRA_FILESYSTEM_LIST gpfs" was now available. Great! I thought I'd try to see if I can see an effect or not.

Cannot use jemalloc with IntelMPI

Hi,

I've tried to bench several memory allocators on Linux (64-bit) such as ptmalloc2, tcmalloc and jemalloc with an application linked against IntelMPI (4.1.3.049).

Launching any application linked with jemalloc will cause the execution to abort with a signal 11. But the same application, when not linked with IntelMPI will work without any issue.

Is IntelMPI doing its own malloc/free ?
How can this issue be overcome ?

Thanks,
Eloi

 

problem when multiple MPI versions installed

Dear all,

I have a problem to launch processes when multiple MPI versions installed. The processes work before I installed latest MPI 5.0.3.048:

C:\Program Files (x86)\Intel\MPI\4.1.3.047>mpiexec -wdir "Z:\test" -mapall -hosts 10 n01 6 n02 6 n03 6 n04 6 n05 6 n06 6 n07 6 n08 6 n09 6 n10 6 Z:\test

However, after I installed MPI 5.0.3.048, the following errors displayed when I launch mpiexec in the environment of 4.1.3.047:

Aborting: unable to connect to N01, smpd version mismatch
