Hello Jeff: Sorry for my delay. To user Intel compiler for openmpi, I removed openmpi installed on my machine and downloaded openmpi 1.2.5 gz file. ./configure script exited with zero. But I find errors in config.log. If any comments/advice can be given, that would be appreciated. My script argument is
./configure CC=icc CXX=icpc FC=ifort F77=ifort --includedir=/opt/intel/cc/10.1.015/include:/opt/intel/fc/10.1.015/include --libdir=/opt/intel/cc/10.1.015/lib:/opt/intel/fc/10.1.015/lib 194 configure:6309: checking how to run the C preprocessor 195 configure:6349: icc -E conftest.c 196 configure:6355: $? = 0 197 configure:6386: icc -E conftest.c 198 conftest.c(37): error #5: could not open source file "ac_nonexistent.h" 199 #include <ac_nonexistent.h> 200 ^ 201 202 configure:6392: $? = 2 203 configure: failed program was: 204 | /* confdefs.h. */ 205 | #define PACKAGE_NAME "Open MPI" 206 | #define PACKAGE_TARNAME "openmpi" 207 | #define PACKAGE_VERSION "1.2.5" 208 | #define PACKAGE_STRING "Open MPI 1.2.5" 209 | #define PACKAGE_BUGREPORT "http://www.open-mpi.org/community/help/"; 210 | #define OMPI_MAJOR_VERSION 1 211 | #define OMPI_MINOR_VERSION 2 212 | #define OMPI_RELEASE_VERSION 5 213 | #define OMPI_GREEK_VERSION "" 214 | #define OMPI_VERSION "5" 215 | #define ORTE_MAJOR_VERSION 1 216 | #define ORTE_MINOR_VERSION 2 217 | #define ORTE_RELEASE_VERSION 5 218 | #define ORTE_GREEK_VERSION "" 219 | #define ORTE_VERSION "5" 220 | #define OPAL_MAJOR_VERSION 1 221 | #define OPAL_MINOR_VERSION 2 222 | #define OPAL_RELEASE_VERSION 5 223 | #define OPAL_GREEK_VERSION "" 224 | #define OPAL_VERSION "5" 225 | #define OMPI_ARCH "i686-pc-linux-gnu" 226 | #define OMPI_ENABLE_MEM_DEBUG 0 227 | #define OMPI_ENABLE_MEM_PROFILE 0 228 | #define OMPI_ENABLE_DEBUG 0 229 | #define OMPI_WANT_MPI_CXX_SEEK 1 230 | #define MPI_PARAM_CHECK ompi_mpi_param_check 231 | #define OMPI_WANT_PRETTY_PRINT_STACKTRACE 1 232 | #define OMPI_WANT_PERUSE 0 233 | #define OMPI_ENABLE_PTY_SUPPORT 1 234 | #define OMPI_ENABLE_HETEROGENEOUS_SUPPORT 1 235 | #define OPAL_ENABLE_TRACE 0 236 | #define OPAL_ENABLE_IPV6 1 237 | #define ORTE_WANT_ORTERUN_PREFIX_BY_DEFAULT 0 238 | #define OMPI_CC "icc" 239 | /* end confdefs.h. */ 240 | #include <ac_nonexistent.h> 241 configure:6425: result: icc -E 242 configure:6454: icc -E conftest.c 243 configure:6460: $? = 0 244 configure:6491: icc -E conftest.c 245 conftest.c(37): error #5: could not open source file "ac_nonexistent.h" 246 #include <ac_nonexistent.h> 247 ^ Thanks!

Specifically: you *might* be able to get away without re-compiling Open MPI, but I wouldn't advise it. You can download the OMPI source tarball from the main web site and configure it with the following to specify the intel compiler suite: ./configure CC=icc CXX=icpc FC=ifort F77=ifort ... You may want to list other configure options, such as --prefix, -- enable-mpirun-prefix-by-default, etc. > 2.

But if possible, it's generally easiest to simply use a single compiler toolset (e.g., all Intel or all GNU). More specifically, unless you have a *need* to mix the compilers, just use a single toolset. -- Jeff Squyres Cisco Systems _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
