building MPICH2 on IA64 with Intel compilers: atomic primitive availability...no

building MPICH2 on IA64 with Intel compilers: atomic primitive availability...no

Hi all:

I'm trying to build mpich2 on an SGI Altix (256-processor IA-64 platform), using the Intel compilers (c/c++ and fortran). If I run configure with gcc, all works fine; the configure completes to the end successfully. However, if I run it specifying the intel compilers, it fails with an error on missing atomic primitive availability...no.

checking for OpenPA atomic primitive availability... no
configure: error:
The nemesis channel was selected yet no native atomic primitives are
available on this platform. OpenPA can emulate atomic primitives using
locks by specifying --with-atomic-primitives=no but performance will be
very poor. This override should only be specified for correctness
testing purposes.

---

The only thing I noticed as signifiant difference between gcc and intel was the note in the intel configure about using locks to perform atomic privilages a couple pages up from the configure error.

My configure line is included in the top of the message. Any assistance would be appreciated...I don't have many systems with the intel compilers and do most of my work with GCC, so I'm a bit uncertian how to proceed.

Thanks!

--Jim

Hi Jim,

Hmm, very interesting question! :-)

Configure checks for GNU asm support! Intel compiler will never support asm on IPF. So, you need to use intrinsics instead but I don't know how to do this.

Regards!

Dmitry
