blacs for sgi mpt

[Faruk_Kujundzic]

I need to compile a software package which requires blacs, however since about composer_xe_2013.5.192 blacs seems to have disappeared from MKL (except blacs for intelmpi and MIC). Where do I get the libmkl_blacs_sgimpt_lp64.a for intel64 for the newest composer_xe?

I moved your issue to the MKL Forum to seek additional help from others from the MKL support team.

I see this file in all Composer XE 2013 updates (2 -5) we have installed.

$ find /opt/intel -name libmkl_blacs_sgimpt_lp64.a
/opt/intel/composer_xe_2013.2.146/mkl/lib/intel64/libmkl_blacs_sgimpt_lp64.a
/opt/intel/composer_xe_2013.3.163/mkl/lib/intel64/libmkl_blacs_sgimpt_lp64.a
/opt/intel/composer_xe_2013.4.183/mkl/lib/intel64/libmkl_blacs_sgimpt_lp64.a
/opt/intel/composer_xe_2013.5.192/mkl/lib/intel64/libmkl_blacs_sgimpt_lp64.a

For the “newest”, meaning Composer XE 2013 SP1 Update 2 (pkg 144), it is also provided in the package and available when installing MKL from what I can see. It is present in all current three releases of CXE XE 2013 SP1.

$ find /opt/intel -name libmkl_blacs_sgimpt_lp64.a
/opt/intel/composer_xe_2013_sp1.0.080/mkl/lib/intel64/libmkl_blacs_sgimpt_lp64.a
/opt/intel/composer_xe_2013_sp1.1.106/mkl/lib/intel64/libmkl_blacs_sgimpt_lp64.a
/opt/intel/composer_xe_2013_sp1.2.144/mkl/lib/intel64/libmkl_blacs_sgimpt_lp64.a

Interesting, I have not noticed any errors during the installation, yet I do not have those libraries. Currently I have 2013 SP1 update 1 installed:

I'll try installing update 2 keeping my eyes peeled for any error messages. Any hints on verbose reporting or logging options for the installer?

[Gennady_F_Intel]

the problem caused by the new Install Option introduced in 11.1 - see more details  here:  http://software.intel.com/en-us/articles/intelr-mkl-new-install-option.  We would recomend you to try reinstall MKL again and select all components you need  to use.

[Faruk_Kujundzic]

D'oh! Thanks, that's it, problem solved. The difference is not easy to spot, perhaps the installer could warn more clearly about this or install a README in the library dir explaining why the blacs libs are missing.

[Gennady_F_Intel]

Faruk, thanks for the feedback, I will ask Install team to look how they can improve the process.
