Problems with execute my code

felipin85 — Sat, 27 Nov 2010 20:28:07 GMT

Hi everybody, I used Ubuntu 10.04 with 32 bit and I'm using Intel Fortran composer xe 2011. I don't understand a problem that I have with my code. When I compile my code with the command: ifort PRINCIPAL27112010.f90 -o PRINCIPAL27112010 and I don't problem, but when I complie using:

ifort -openmp -O3 -o PRINCIPAL27112010 -I$MKLINCLUDE -L$MKLPATH PRINCIPAL27112010.f90 -lmkl_lapack95 -Wl,--start-group $MKLPATH/libmkl_intel.a $MKLPATH/libmkl_intel_thread.a $MKLPATH/libmkl_core.a -Wl,--end-group -liomp5 -lpthread

I received the following error:

I need using mkl_dss.f90 for using sparse arrays. This is reason for using ifort -openmp -O3 -o PRINCIPAL27112010 -I$MKLINCLUDE -L$MKLPATH PRINCIPAL27112010.f90 -lmkl_lapack95 -Wl,--start-group $MKLPATH/libmkl_intel.a $MKLPATH/libmkl_intel_thread.a $MKLPATH/libmkl_core.a -Wl,--end-group -liomp5 -lpthread,

Thanks

Your program has many errors, including (i) mismatches between the types of actual and dummy arguments, and (ii) uninitialized variables. You can locating these errors by compiling the source code with the -warn interfaces option.

Until you correct those errors, it is pointless to try parallelizing the runs.

Very thanks mecej4!

Ok, I have corrected. Now, I like use mkl_dss for solution mi system. Have I add something the compilation or the last line is valid for use lapack95 and in the same moment use mkl_dss solver. I know that in theory the line past run ok, for probe file, but I don't know especif the use mkl_dss in compilation, in the file, I know that I have write include mkl_dss.f90 before the program.

Thanks

Sorry, I cannot decipher your English to the point where I can give a proper reply. Perhaps, you can retry with shorter sentences.

Please set MKLPATH env and use it correctly in makefile:

instead of $MKLPATH there should be $(MKLPATH)

Note that MKL Link Advisor suggests only command line notation.

Ok, very thanks Victor Pasko. You were right, I forgot the parentheses. Thanks.

And, the other mistake? Do you know how to fix?

Thanks, Regards

Felipe

Could you please minimize your testcase (to not use also your local path/home/Placas/) in order to analyzeyour problem with memory corruption.

felipin85 — Wed, 01 Dec 2010 11:57:34 GMT

Victor, thanks for your response. I changed the code linking, I erase -openmp or I don't know that I changed but, but the problem of corruption I have not. As if I were to happen, usually where the corruption?

Thanks, for your help

Memory corruption is very difficult to analyze in debugger. There exist some tools which can help.
Firstly, please try valgrind. But the most simple way is to read your program very carefully looking at arrays underindexing and overindexing

If you are using Intel Fortran compiler please trysource code analysis and check options:

-diag-enable [,,...]
enable the specified diagnostics or diagnostic groups
-diag-disable [,,...]
disable the specified diagnostics or diagnostic groups
where may be individual diagnostic numbers or group names.
where group names include:
sc - perform source code analysis: n=1 for critical
errors, n=2 for all errors and n=3 for all errors
and warnings
sc-include - perform source code analysis on include files
sc-parallel - perform analysis of parallelization in
source code: n=1 for critical errors,
n=2 for errors, n=3 for all errors and
warnings

-[no]check
check run-time conditions. Default is -nocheck
keywords: all (same as -C), none (same as -nocheck),
[no]arg_temp_created, [no]bounds (same as -CB),
[no]format, [no]output_conversion,
[no]pointer (same as -CA),
[no]uninit (same as -CU)

Yes, I'm using Intel Fortan. Thanks for the information, This is very useful. But, in my make file,specify where these conditions?
Thanks
