Re: [OMPI users] MPI_File_write_shared() and MPI_MODE_APPEND issue ?

ght 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,

[OMPI users] MPI_File_write_shared() and MPI_MODE_APPEND issue ?

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

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). Thank

Re: [OMPI users] MPI_Finalize() small issue with mutex destruction

I) 1.10.1 I discovered it with 1.10.1, and was able to reproduce with older versions 1.6.5 and 1.8.8 i had handy. Thanks. > > On May 19, 2016, at 9:06 AM, Nicolas Joly wrote: > > > > > > Hi, > > > > I just discovered a small issue with MPI_Finalize(). When sanity

[OMPI users] MPI_Finalize() small issue with mutex destruction
