Re: [Wien] Intels Oneapi 2024: Compiler bug ?

2024-01-26 Thread Peter Blaha 
Yes, ifx cannot be used at the moment. It is very limited by now and 
produces many errors during compilation.
It is a bit worrying, since ifort (2024) gives an info that it will be 
disabled next year 


Most of the time I tried   -O3  it did:
not significantly improve timing (sometimes it was even slower)
sometimes it produced even errors during execution.

The performance of -O3 depends a lot on the compiler version and may 
change with each version. You will have to benchmark it yourself, but 
don't expect too much.


using AVX flags or -Xhost   is possible when you have only one type of 
cpu where the code should run. But again, all you gain is that the 
executables get smaller and may load faster, because by default code for 
all kind of cpus will be generated. The overhead of determining which 
one to use is in my experience small, although I have not tested this 
much since I usually have several different kind of cpus available.

Hello all,


I tried also to use ifx .. it works for elpa, mpich, fftw and libxc, but 
the compilation of WIEN2k has too many errors. With the classic compiler 
ifort the compilation works fine and also the workaround for SRC_wplot 
does resolve the compilation error.


Elpa recommends flags for certain cpu structures using AVX512, AVX2 etc 
and uses -O3 instead.



I was wondering if using "-O3 -xAVX2" in the compiler flags brings 
better performance of the WIEN2k code or if its counterproductive and I 
should stay with the recommendations?

I have rarely seen -O3 help, I only use -O2
You may want to use -xHost, if you have only one type of cpu. Safer.

the compilation of WIEN2k has too many errors. With the classic compiler 
ifort the compilation works fine and also the workaround for SRC_wplot

It appear ONLY with the most recent oneapi 2024.0, not with older

Thus the question is: Is this a compiler bug or is this due to a very 
new fortran-standard which this version enforces ?
Has anybody an even newer gfortran (higher than version 12) and can 
test it with this compiler ?

Maybe there is a Fortran expert who knows if this syntax is correct or 
not.


A user reported recently a compilation problem using   the most recent 
ifort (or ifx, which will become soon the new fortran compiler) 
(oneapi-2024.0)   in SRC_wplot:


ifx -O -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML -traceback 
-assume buffered_io -I/home/aarav/intel/mkl/2024.0/include 
-DHAVE_PTR_ALLOC_GENERICS -Ilib -free -gen-interface nosource 
-traceback -g -I../SRC_w2w/lib -I../SRC_w2w/lib -c modules.f 
-olib/modules.o -module lib
modules.f(195): error #6911: The syntax of this substring is invalid. 
[CART]

   inw%grid%len = (/( sqrt(sum( inw%grid%Cart(:,i)**2 )), i=1,3 )/)
-^

So the error is in line 195 of SRC_wplot/modules.f.

It appear ONLY with the most recent oneapi 2024.0, not with older 
versions nor with gfortran-12.


Thus the question is: Is this a compiler bug or is this due to a very 
new fortran-standard which this version enforces ?
Has anybody an even newer gfortran (higher than version 12) and can 
test it with this compiler ?
