[mvapich-discuss] Intel Xeon Phi support?

[Jonathan Perkins]

Thanks for the note Nikos.  I think this issue can be fixed by adding
some LDFLAGS to your configure step of mvapich2.  Can you locate the
mic (k1om) version of libimf.so on your system?  It should be
somewhere in your intel compiler installation.

Using the following location as an example:
/opt/intel/composer_xe_2013_sp1.1.106/compiler/lib/mic/libimf.so

You should add the following LDFLAGS to configure:
LDFLAGS='-L/opt/intel/composer_xe_2013_sp1.1.106/compiler/lib/mic
-Wl,-rpath,/opt/intel/composer_xe_2013_sp1.1.106/compiler/lib/mic'

Please also note that CPPFLAGS should not contain -mmic.  That
variable is used by the c pre-processor and should be used for -I and
-D settings.  Let us know if this helps.
