SIGSEV error while adding SIMD instruction

Hi all I rewrote a program for exploiting SIMD.

However I seem to be encountering a problem of segmentation fault. How do I find whats wrong?

Attached are the files program and test program with SIMD that fail's.

while test.F90 is just loop.F90 with minor modifications for some reason it fails. and I dont know why.

I use the intel 15 set of compilers

Any help? 

Advanced Hotspot analysis problem

I’m trying to analyse an OpenCL program with VTune Amplifier XE 2015 (update 4) using VS2010 and VS2013 on Windows 7 enterprise.

Under "Algorithm Analysis", I choose 'Advanced Hotspots", and then select, from the "Analyze Processor Graphics hardware events" dropdown, either "Overview" or "Compute Basic", I get the banner message:

 “Processor Graphics analysis is only available on systems with Intel HD graphics and Intel Graphics Driver installed.

dapl with MPSS 3.5 and Qlogic HCA

I am running MPSS 3.5 and OFED+ and have 2 nodes with Phi cards and Qlogic. I believe that if I set I_MPI_FABRICS to use  either tcp or tmi everything works, but I've heard that dapl is faster and I'm having problems getting that to work everywhere. It works when MPI tasks are either only on the hosts or only on cards in a single host. If there are tasks on the host and a card it appears to have problems connecting to the IP address that is added during the ofed-mic service startup (

PARDISO segfault in 64 bit mode on Mac OS X


I am using Intel MKL version 11.2 update 3 (latest I believe) on Mac OS X Yosemite (10.10.3). Specifically I am noticing that the PARDISO direct sparse solver is crashing in the 64 bit mode (compiled with -DMKL_ILP64 -m64). It runs fine in the 32 bit mode.  My matrix size is 10000 with about 1 million non-zeros. Are there any known issues with the above system configurations ? Any help is appreciated. 




cannot analyze user tasks with update 4

Starting with 2015 update 4, vtune seems to be unable to analyze user tasks, erroring upon capture completion. I've bounced back and forth a few times between updates 3 and 4, and it only started happening with 4. I could reinstall 4 to get the error messages, but is this already a known issue?


GROMACS recipe for symmetric Intel® MPI using PME workloads


This package (scripts with instructions) delivers a build and run environment for symmetric MPI runs. This file is actually the README of the package. Symmetric stands for employing a Xeon® executable and a Xeon Phi™ executable both running together exchanging MPI messages and collective data via Intel MPI.
