forrtl: error (78): process killed (SIGTERM)


I get the following runtime error on our Beowulf cluster with an parallel MPI Code compiled with ifort:

forrtl: error (78): process killed (SIGTERM)
PSIlogger: Child with rank 0 exited with status 1.

PSIlogger: done

How can I find out more about this error, where and why it
occurs? Debugging works not for the parallel code for some reason.

Thanks in advance,


Intel fortran 50% slower than g77?

I'm new to intel fortran and after installing ifort (9.1.029) on my brand new imac 24" (2.33GHz) I wanted to see how much faster it is than gnu fortran (g77) on the following trivial program:

do i=1,10**9



end do

print*, s


To my horror I found the following results:

$ g77 1.f

$ time a.out


real 1m3.011s

user 1m2.828s

sys 0m0.055s

ifc kdevelop


I am trying to setup ifc to work with kdevelop.

So far I have managed to create the default hello world and compile and run it with ifort.

I have full debugging working for other Linux projects like gimp using gdb-6.5

I have spent several days searching for info on using either idb or gdb but have found precious little info on this subject.

Can you point me to some help on doing this?

It also seems this I do not have idb installed in /opt/intel , is this not supplied with ifc Linux or have I missed a step?

fortcom: Severe: **Internal compiler error: internal abort**

Hi all,
I uncountered an internal compile error using ifort v9.1.036 (but the same error shows up also with v9.0.031) . The code compiles fine with g95 or pgf90.

The error:

ifort -O3 -c ./kiva3d/timstp.f


fortcom: Severe: **Internal compiler error: internal abort** Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error.

poor parallel speedup of sample program: jacobi.f


I am trying to run the "jacobi.f" sample program provided on the website:

have not been able to achieve any kind of parallel speedup when I
compile and run this program with intel fortran compiler for linux.

Has anyone had sucess with this program using intel fortran linux compiler ? Any explicit ode solver ?
What is necessary to achieve parallel speedup with the openmp "jacobi.f" sample program ?

REAL(4) to REAL(8) conversion

Dear All,

I have a problem with a real number conversion. I would like to convert a single precision real number into a double precision. I wrote a simple program which uses DBLE() function.

% cat conversion.f
program conversion

real(4) sx1
real(8) dx1

write(*,*) sx1,dx1


When I run the program I get the following result:

% ./conversion
1.000010 1.00001001358032

I wish that the result of conversion is 1.00001000000000 (or perhaps 1.00001000000001 or. 1.00000999999999).

-r8 option makes deallocate fail

hi i am using fortran for linux 9.0
i have a bunch of legacy code written in f77 and there all real declaration are real*8 ,

i have been coding in f90 free format , and i wrote my modules and libraries and and have other people's libraries also in f90, here the declararation are simply real , and use some allocateble arrays

i added in my makefile the -r8 option for my f90 files and it compiles with no warning any time i run i got 'error glibc detected double free or corruption '
when i try to deallocate the arrays ,
