HPL over Xeon Phi compilation error

[francesca_tartaglion]

Dear all,

I'm trying to compile HPL-2.1 on a system which has two Intel Xeon Phi.

The sytem has CentOS 6.3 and I've installed the following Intel tools: l_ccompxe_2013.2.146, l_fcompxe_2013.2.146, l_mpi_p_4.1.0.030.

I have set manually the follogind variables:

source /opt/intel/bin/iccvars.sh intel64
source /opt/intel/bin/ifortvars.sh intel64
source /opt/intel/mkl/bin/mklvars.sh intel64
source /opt/intel/impi/4.1.0/mic/bin/mpivars.sh
export LD_LIBRARY_PATH=/opt/intel/impi/4.1.0/mic/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/intel/mkl/lib/mic:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/intel/composer_xe_2013.2.146/compiler/lib/mic:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/intel/composer_xe_2013.2.146/compiler/lib/intel64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/intel/composer_xe_2013.2.146/compiler/lib/ia32:$LD_LIBRARY_PATH

and in the HPL make file I've set the variable values as you can see from the make.Intel file attached.

I tried to compile but, after some time, it returned this error:

x86_64-k1om-linux-ld: i386:x86-64 architecture of input file `/opt/hpl-2.1/lib/mic/libhpl.a(HPL_dlamch.o)' is incompatible with k1om output
make[2]: *** [dexe.grd] Error 1
make[2]: Leaving directory `/opt/hpl-2.1/testing/ptest/Intel'
make[1]: *** [build_tst] Error 2
make[1]: Leaving directory `/opt/hpl-2.1'
make: *** [build] Error 2

I've also put in attachment the output file.

Do you have any suggestion about how to solve this issue?

Thank you very much in advance!

Looking at your output.txt, it appears that all the code except HPL_dlamch.o is compiled using the -mmic option. It looks like that routine compiled with "CCFLAGS = $(HPL_DEFS)"  rather than  "CCFLAGS  = $(HPL_DEFS) -mmic -O3 –openmp"

Dear Frances,

thank you very much for your observation, actually it helped me a lot, now I've just compiled HPL successfully.

Thanks again
