Intel® Fortran Compiler for Linux* and Mac OS X*

catastrophic error: **Internal compiler error: segmentation violation signal raised**

I have installed the latest Intel Cluster 2016 Update1 and here is the error message I get when compiling the following realspace_grid_types.f90 file with the command 

mpiifort -FR -c -O2 -pc64 -unroll -qopenmp -heap-arrays 64 -lmkl_scalapack_lp64 -lmkl_intel_lp64 -lmkl_core -lmkl_intel_thread -lmkl_blacs_intelmpi_lp64 -lpthread -lm

here is the mpiifort version:

run time -- some questions

Dear all, 

I have written a very long code, with many subroutines.

In this moment I am runnung some simple run-time analysis with 


I have notice something strange. When I increase the number of cycle in may code the running time increases not linearly. 

I mean if I do four cycles instead of two, the running time does not double but is is greater. 

Difficulty with launching Fortran app in OS X

I posted this before a few days ago but have received no replies.

Previously I developed a pretty simple Fortran in Xcode and ran it without any real problems (OS X 10.10) as command line. Now it will build but not launch. I have upgraded to Xcode 7.1.1 but no difference. I have upgraded the compiler to the 2016 version .Although I have not tried it before i have t just run the compiler from the command line and get this result.

Catastrophic error with v16.0/1 but not with v15.x


The update 1 and initial release of ifort v16 are leading to a catastrophic error during the compilation of a large fortran code (>100kLOC) while everthing is ok with v15.x.

For the same code, v15 takes about 5min to compiler the entire code and v16 try to compile during several hours, and then crashes (the same compilation option being used).

So there is definitely something going wrong with v16.

The problem is, I have no way to make a short reproducible example.

Moreover, I do not have an intel premium account.

error on many cores run


I have a code that works on a cluster when I use 6^3 = 216 cores, but the code crashes when I try to make it run with an higher resolution using a 12^3 = 1728 cores (all the parameters are the same except the grid spacing and the number of processors with which the code work).

We tried to see if it is a memory issue but even running the job with 16 tasks per nodes (108 nodes) didn't help.
I cannot debug the program with something like totalview because of the limit of processes these debuggers can manage.

RPM repo or Intel Software Manager for Linux ?

Are there any plans to introduce an Intel Software Manager for Linux like there is on Windows?

Such that any new software upgrades are automatically found and reported to the Linux user ?


Is there any plan to introduce a RPM repository so that the existing automated tools in Linux ( dnf/yum) can regularly check for updates ?

Fundamentally I'm after automated tools (or the ability to rely on existing tools) to check and notify for updates. Relying on emails and or manual checks can be a little hit and miss at times.
