Hi Jian and Abhishek, Thanks for reporting this. When configured with --enable-thread-cs=per-object, MPID_cc_t will be defined as OPA_int_t, which can not be directly compared with 0 using "==". I will create a patch for this.

Hi, Abhishek,

Thanks for your note. By using the full configure options you provided, we are able to reproduce this behavior. However, MVAPICH2 2.1rc2 is based on MPICH 3.1.4. We found that the error also exists with the MPICH 3.1.4/3.2b1 even if using ch3:nemesis device. It will be good if the MPICH team resolves this. I am cc'ing this note to the MPICH team.

Hi, MPICH community,

The forwarded compilation error reported by the user is related to unmatched MPID_cc_t typedefs if some thread-related configure options are used. The default build without these thread-related options does not have any issue. Will you please take a look. Thanks!

Jonathan,

I am using the following configure flags:

./configure --enable-threads=multiple --enable-async-progress --with-device=ch3:psm --enable-thread-cs=per-object CFLAGS=-O3 --enable-refcount=lock-free --enable-handle-allocation=tls --with-atomic-primitives

The distribution is Ubuntu 12.04.5 LTS and the compiler version is gcc (Ubuntu/Linaro 4.6.4-1ubuntu1~12.04) 4.6.4.

Thank you for your report. When trying to reproduce this problem locally I am running into a similar but different build error. Can you provide us more information on how you're building? Please let us know the Linux distribution and version and vendor of the compiler that you're using.

Hello,

While trying to build mvapich 2.2rc2, I run into a build failure when I use the following two flags together: --with-device=ch3:psm --enable-thread-cs=per-object

Is this a known issue? Since I expect to mostly run in a hybrid (OpenMP+MPI) configuration, I am assuming that the granularity of critical sections might be critical for good performance.
