The Intel® MPI Library for Linux* and Windows* is a high-performance interconnect-independent multi-fabric library implementation of the industry-standard Message Passing Interface, v2.2 (MPI-2.2) specification. This package is for MPI users who develop on and build for IA-32 and Intel® 64 architectures on Linux* and Windows*, as well as customers running on the Intel® Xeon Phi™ coprocessor on Linux*. You must have a valid license to download, install and use this product.
Intel MPI 4.1.3 on RHEL6.4: trying to bind ranks in two simple fashions:(a) 2 ranks to the same processor socket and (b) 2 ranks to different processor sockets.
Looking at the Intel MPI Reference Manual (3.2. Process Pinning pp.98+), we should be able to use options in mpiexec.hydra when the hostfile points to the same host

The Intel® Parallel Studio XE 2015 Cluster Edition for Linux* and Windows* combines all Intel® Parallel Studio XE and Intel® Cluster Tools into a single package. This multi-component software toolkit contains the core libraries and tools to efficiently develop, optimize, run, and distribute parallel applications for clusters with Intel processors. This package is for cluster users who develop on and build for IA-32 and Intel® 64 architectures on Linux* and Windows*, as well as customers running over the Intel® Xeon Phi™ coprocessor on Linux*. It contains:
This page provides the current Release Notes for the Intel® Parallel Studio XE 2015 Cluster Studio products. All files are in PDF format - Adobe Reader* (or compatible) required. The Intel® Parallel Studio XE 2015 Cluster Edition Release Notes are a superset of the Intel® Parallel Studio XE 2015 Professional Edition and Intel® Cluster Tools Release Notes.
First i have to provide this information:
1- i have instaled the latest version of Intel MPI.
2- i have to use it through Ansys HFSS 15 x64 which is a EM-software.
3- HFSS dont have any problem with discrit processes (for ex. 15 paralel process will share trough 3 computer on network correctly)
4- i need to use memory of other computers on the network, so need distribute the RAM usage.
5- the error i got every time is "authentication faild" or "unable to create child process in hosts" (or somthing like these)
Dear developers of Intel-MPI,
I found, that the helpful option -prepend-rank does not work when launching a parallelized Ftn-code with mpirun when using INTEL MPI-5.0 :
mpirun -binding -prepend-rank -ordered-output -np 4 ./a.out
The option actually has no effect with INTEL MPI-5.0 (with INTEL MPI-4.1 it worked). No rank-numbers are prepended on the display to the output lines of the program.
Dear developers of Intel-MPI,
First of all: Congratulations, that INTEL-MPI now supports also MPI-3 !
However, I found a bug in INTEL-MPI-5.0 when running the MPI-3 shared memory feature (calling MPI_WIN_ALLOCATE_SHARED, MPI_WIN_SHARED_QUERY) on a Linux Cluster (NEC Nehalem) by a Fortran95 CFD-code.
I have a cluster with two kinds of nodes joined into parallel calculation: the first kind is the nodes with 2 CPUs and 4 cores in every CPU, the memory in every node is 32 GB, the second kind is the nodes with 4 CPUs and 8 cores in every CPU, the memory in every node is 256 GB. All nodes have Windows Server 2008 HPC in stalled and they are all joined into one domain controlled by another node (which is not joined into the calculation). I launched the job by the following command:
I noticed that Intel has release Intel MPI 5.0 and I downloaded latest version to test it. The command I used is as follows (it works with latest Intel MPI 4.1.x):
mpiexec -wdir D:\Users\tang\Debug -mapall -hosts 1 n01 1 D:\Users\tang\Debug\fem
However, the following error messages displayed:
The Intel® Trace Analyzer and Collector for Linux* and Windows* is a low-overhead scalable event-tracing library with graphical analysis that reduces the time it takes an application developer to enable maximum performance of cluster applications.
