se, it might be too late for that. No hurry. We are in the process of validating our codes with the new ompio backend ... And we still have romio as a fallback. Thanks again. > Thanks for the bug report! > > Edgar > > > On 1/18/2017 9:36 AM, Nicolas Joly wrote: > >Hi,

e shared file pointer was reset/initialised(?) to zero ... leading to an unexpected write position for the "Data line" buffer. Thanks in advance. Regards. -- Nicolas Joly Cluster & Computing Group Biology IT Center Institut Pasteur, Paris. #include #include #include #define

[OMPI users] Small typos in MPI_Info_get_nkeys/MPI_Info_get_nthkey man pages

2016-10-23 Thread Nicolas Joly
Hi, Just noticed a typo in MPI_Info_get_nkeys/MPI_Info_get_nthkey man pages. The last cross-reference is 'MPI_Info_get_valueln' where it should be 'MPI_Info_get_valuelen'. The attached patch should fix them. AFAIK all versions are affected (master, 2.x and 1.10). Thanks. -- Nicolas Joly

other thread results in undefined behavior. [...] Any expected issue in adding a opal_mutex_unlock() call before destroying the opal_mutex_t object ? Thanks.
