[mvapich-discuss] --with-limic2=/usr/local/limic2-0.5.6 seems to be ignored

[Hashmi, Jahanzeb]

Hi Jim,

It looks like you are installing Limic in non-default location (/usr/local is the default location). This is fine as long as you specify the paths to 'lib' and 'include' directories as well when installing mvapich2 with Limic support.

[hashmij at haswell3 mvapich2-2.3.3]$ ./configure --help | grep limic2
  --with-limic2=[LiMIC2 installation path]
  --with-limic2-include=[LiMIC2 include path]
  --with-limic2-libpath=[LiMIC2 library path]

>From your configure line, I do not see it happening. The correct mvapich2 configuration in your case should look like this:

"--with-limic2=/usr/local/limic2-0.5.6 --with-limic2-include=/usr/local/limic2-0.5.6/include --with-limic2-libpath=/usr/local/limic2-0.5.6/lib"

Also, you are specifying '--with-hwloc' which is extraneous since mvapich2 will automatically build the hwloc from contrib/hwloc.

Please let us know if this configuration works for you.

Best regards,
Jahanzeb

Subject: [mvapich-discuss] --with-limic2=/usr/local/limic2-0.5.6 seems to be ignored

After building limic2 with -

./configure --enable-module --sysconfdir=/etc —prefix=/usr/local/limic2-0.5.6
make
make install

Building mvapich2-2.3.3. results in this error,

./configure --with-limic2=/usr/local/limic2-0.5.6  LDFLAGS='-Wl,-rpath=/usr/local/limic2-0.5.6/lib' --with-hwloc --prefix=/usr/local/mpi/mvapich2/mvapich2-2.3.3-gcc-8.3.0

But after copying the limic2 libraries to /usr/local/lib

#cp /usr/local/limic2-0.5.6/lib/*limic*   /usr/local/lib


The build is successful -


./configure --with-limic2=/usr/local/limic2-0.5.6  LDFLAGS='-Wl,-rpath=/usr/local/limic2-0.5.6/lib' --with-hwloc --prefix=/usr/local/mpi/mvapich2/mvapich2-2.3.3-gcc-8.3.0

Configuration completed.



This was performed on a RedHat 7.7 system.  Having /usr/local/limic2-0.5.6 in /etc/ld.so.conf.d/limic.conf makes not difference -

[root at iforgehn1 ld.so.conf.d]# cat /etc/ld.so.conf.d/limic.conf
/usr/local/limic2-0.5.6/lib

[root at iforgehn1 ld.so.conf.d]# ldconfig -p | grep limic
        liblimic2.so.0 (libc6,x86-64) => /usr/local/limic2-0.5.6/lib/liblimic2.so.0
        liblimic2.so (libc6,x86-64) => /usr/local/limic2-0.5.6/lib/liblimic2.so
