Simple HelloWorld with Intel 11 (Fortran and C/C++)

I am trying to create a simple helloworld.for and helloworld.cc to prove my Intel 11 compiiler is correctly installed on my RedHat linux box but get the following errors:

icc helloworld.cc
ld: cannot find -limf

ifort helloworld.for
ld: /opt/intel/Compiler/11.0/074/bin/lib/for_main.o: No such file: No such file or directory

Any idea what is going on? I can get these working finr with the old version 10 compiler.

Thanks.

Intel MPI Benchmark woes on Itanium2

Firstly apologies if there's a thread already on this (I couldn't find anything with the limited search facilities available)

The crux: I've downloaded the Intel MPI Benchmarks (IMB) and compiled on Itanium-2 chips using mpich2/icc. However I have had several problems, see below, so was hoping to share experiences with others - let me know what you've found!

The problems so far:

1) MPI-IO benchmark suite hangs just after:

Segmentation fault with ifort -openmp

Processor info : Intel dual processor, quad code

Memory : 16GB

I have been able to compile and run my code in the serial mode. However, after including 'omp_lib.h' and with Openmp worksharing constructs, I get Segementation fault, which happens even if I remove the worksharing constructs. i.e

The program runs with ifort < > -o <>

failes with ifort -openmp <> -o <> (Even after commenting(removing) the OMP pragmas)

I have tried increasing environment variable KMP_STACKSIZE, but that is not help ful.

mpd problems

Hi all,

I'm using Intel-MPI 3.2.011 on a cluster with 9 nodes and 36 cpus and a master node with 2 cpus. Ethernet interconnects all nodes.

The mpdboot commands on master:

/opt/intel/impi/3.2.0.011/bin64/mpd --ncpus=2 -e -d &

/opt/intel/impi/3.2.0.011/bin64/mpdboot --rsh=/usr/bin/ssh --totalnum=10 -1 --file=$HOME//machines.LINUX --verbose --ncpus=2 &b

bring out on nodes the daemon:

mpirun : [Errno 2] No such file or directory

Hello,

I use impi 3.0 on a Linu 64b Xeon cluster. On the service node, I am not able to run any program with mpirun :

mpirun -np 2 -v ./myprogram
running mpdallexit on service0
LAUNCHED mpd on service0 via
RUNNING: mpd on service0
problem with execution of ./myprogram on service0: [Errno 2] No such file or directory

Same error if I put the whole path to my program or a system program (for instance /bin/hostname).

It works on compute node perfectly.

$PATH seems fine :

Cluster OpenMP for Intel Compilers

Dear all,

I would like to thank you first for reading my Thread. I will try to be as precise as possible.

I am an Intel Visual Fortran 10.0.0.27 for Windows(happy) customer. Our programs are mainly a mix between Fortran (Compiler Intel)and C++ (Compiler VS 8.0 from Microsoft). We only use a single processor machine to run programs.

In a context of a future parralelization of our simulation softwares on distributed systems,I reached the " cluster OpenMP for Intel Compilers" page which leads me to the following questions:

How to downgrade Intel Cluster Toolkit Compiler Ed. for Linux?

We work at University of Vigo in Spain and we have an SGI machine, an Altix 450, with a SUSE 10 installed. We've got the "Intel Cluster Toolkit Compiler Edition for Linux" with these versions of the compilers:

intel_cc_10.1.008;
intel_mpi_3.1
intel_mkl_10.0.11
intel_idb_10.1.008
intel_fc_10.1.008

But we've to install/compile a software (Gaussian) that doesn't support this wersion of the compilers.

We need this other version of the compilers:
