Re: [OMPI users] Fail to lock/unlock a shared memory window iteratively

There was a bug in the MPI_MODE_NOCHECK path in osc/sm. It has been fixed on master and a fix has been CMRed to 1.8. Thank you for reporting this. In the meantime you can remove MPI_MODE_NOCHECK and it should work fine. -Nathan On Thu, Feb 12, 2015 at 11:10:59PM +0100, Thibaud Kloczko wrote: >

[OMPI users] Fail to lock/unlock a shared memory window iteratively

2015-02-12 Thread Thibaud Kloczko
Hi all, Here is my problem (see attached file for more details). I create a window using MPI_Win_allocate_share d. The rank 0 is then in charge to fill iteratively the shared buffers using the MPI_Put function. At each iteration, I use also MPI_Lock and MPI_Unlock function as follows: MPI

Sorry for not replying earlier. Yes, you hit on a solution. Note, too, that the MTLs are only used by the "cm" PML, and the BTLs are only used by the "ob1" PML. So if you're using the openib BTL for IB support (vs. the MXM MTL), you can effectively choose one or the other by setting OMPI_MCA

I have just solved my problem by specifying export LD_PRELOAD=libjvm.so-directory/libjsig.so; before the call to mpirun. In my case it missed signal chaining ( http://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/signals.html ). 2015-02-11 20:30 GMT+01:00 Jeff Squyres (jsquyres) : >
