If we are using evaluation version of Intel MPI/compiler/MKL (cluster tools) how many cores/processes we can run HPL on?
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
Has intel made a statement as to the last know good version of Red Hat that supports Intel MPI 3.2.2.006. We have a new cluster with 20 cores/per node and have observed a fortran system call failing when more than 15 core per node are used. This machine is running Red Hat 6.6 x86_64.
Alternatively are their known conditions where Intel MPI 3.2.2.006 will fail.
In MPI_5.0.3, the MPI_TAG_UB is set to be 1681915906. But internally, the upper bound is 2^29 = 536870912, as tested out by the code attached.
Same code will run just fine in MPI 4.0.3.
Just to let you guys know the problem.
Hope to see the fix soon. Thanks.

Looks like on Linux the intel MPI runtime hardcodes the path of mpivars.sh, eg:
I_MPI_ROOT=/opt/intel/impi/4.1.3.049; export I_MPI_ROOT
On windows on the other hand the path is dynamically generated:
Is there any reason to why the path cannot also be automatically generated on Linux?
I just received my serial number of single user Intel Cluster Studio 2015 (Linux). I had done product registration and generated a license file. However, the license file generation page didn't show any information or steps of "how to apply the license file"...
I am using an evaluation version of Intel Cluster Studio 2015 in Linux workstation. So, I want to use the above license file. I copy the license file into /opt/intel/license folder. Do I need to execute any command? Is there any guidelines or info.
Under Linux OS, I built my MPI application with Intel MPI 5.0.2.044. There is no error in compiling but there are following error in linking MPI library.
I am using the Intel MPI's libmpifort.a and libmpi_mt.a for linking my application.
LIBS = -L/opt/intel/composer_xe_2013_sp1.2.144/mkl/lib/intel64 -lmkl_intel_lp64 \

If you are compiling your program with Intel® MPI Library Version 4 and adding the Intel® Trace Analyzer and Collector Version 9 (Initial Release or Update 1 only) at compile or link time via the -trace option, you will encounter linkage problems, similar to the following:
The Intel® Parallel Studio XE 2015 Update 2 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*.
