Pierre,
The problem seems to come from the fact that we do not detect how to
generate the assembly code for our atomic operations. As a result we fall
back on the gcc mode for 32 bits architectures.
Here is the corresponding output from the configure script:
checking if cc supports GCC inline assembly... no
checking if cc supports DEC inline assembly... no
checking if cc supports XLC inline assembly... no
checking if CC supports GCC inline assembly... no
checking if CC supports DEC inline assembly... no
checking if CC supports XLC inline assembly... no
checking for assembly format... default-.text-.globl-:--.L-@-1-0-1-1
checking for asssembly architecture... IA32
But there is something strange with the system you're compiling on. The
size of a C pointer is detected as 8 bytes, so this system is running in
64 bits mode.
Dear George,
Yes, the system is running in 64 bit mode. Also I enforced the options
-xtarget=opteron -xarch=amd64 to produce 64-bit objects.
The default for Solaris 10 is 32-bit compatibility mode. This is
probably why the system reports as i386-pc-solaris2.10.
However, configure report it as a i386-pc-solaris2.10
(basically a 32 bits mode).
Give us one or two days to find a fix.
Sure !
Documentation for Solaris 10 is available on the Sun web page. Also, if
you are interested in an account on our machine, you may ask to
Francoise Roch.
All the best for open-mpi.
Pierre.
Thanks,
george.

Hi,
I tried to experiment open-mpi on our Solaris10 v40z cluster hoping it
might surpass lam/mpi 7.1.2b28...
I used the following script to compile in 64 bit mode:
#! /bin/tcsh -v
setenv CC "cc"
setenv CXX "CC"
setenv FC "f95"
setenv CFLAGS "-O -xtarget=opteron -xarch=amd64"
setenv CXXFLAGS "-O -xtarget=opteron -xarch=amd64"
setenv FFLAGS "-O -xtarget=opteron -xarch=amd64"
setenv LDFLAGS "-xtarget=opteron -xarch=amd64"
setenv CXXLDFLAGS "-xtarget=opteron -xarch=amd64"
./configure --prefix=/users/valiron/lib/openmpi-1.0.1rc5
make
The configure runs fine and the make aborts very rapidly.
I attach the log for configure+make and the config.log file.
Any idea ?
Pierre.
