[OMPI devel] Problem with BTL while allocating window

2017-02-02 Thread Clement FOYER
Hi everyone, I've been facing issues with the creations of windows (MPI_Win_create). Maybe it's an already known issue, or maybe you will be able to tell me where to check to find the problem. I've been developping some benchmark to evaluate the overhead of a monitoring module. Everything

[OMPI devel] Minor typo in opal/class/opal_list.h

2017-02-23 Thread Clement FOYER
Hi everyone, I found a typo in the comment for the opal_list_item_compare_fn_t typedef (opal/class/opal_list.h:877). It says the functions should return "11" instead of "-1" for a < b. Should I open a issue on the github, or is there already a thread where to add minor typo mistakes, or

[OMPI devel] Removing from opal_hashtable while iterating over the elements

2016-11-18 Thread Clement FOYER
Hi everyone, I was wondering if it was possible to remove an element while iterating over the elements of a hashtable. As saw that it wasn't while using the OPAL_HASHTABLE_FOREACH macro, and I suppose it's because of the possible loss of the current next element. But how about if the element

Hi everyone, I've got two Makefile configuration problems, and I thought maybe someone here could give me hints to resolve them. I've been working on a component that is part in ompi/mca/pml/comp, and part in mca/common/comp. And I don't really know which variables/target to set in order to

Hello everyone, I have been trying to redirect MPI_Init and MPI_Finalize calls from a FORTRAN application (the CG benchmark from NAS Parallel Benchmarks). It appears that in the fortran application the MPI_Init function signature is "mpi_init_", whereas in my shared object it is MPI_Init. How

As George pointed out earlier, there is no construct in C able to tell you if a random number is a valid C pointer, i.e., is a valid memory address. -1, once casted to a pointer, would correspond to the adress 0x...f . It would probably be better to ajust the initial code in order to use

Hi Brian, Even if I see your point, I don't think a user request de free the communicator should necesserily lead to the communicator being deleted, only released from one hold, and available to be disposed by the library. I don't see objection to have the library keep a grab on these

Hi, The reason you cannot find it is because it actually is not define as such. The PMPI interface is defined as the profiling interface. The principle is you have the real symbol in your shared library that is PMPI_Send, with a weak alias being MPI_Send. So, if a third party want to intercept
