That depends on the creation/access patterns you want to support and the number of hoops that you want to jump through. Jesper published a very reasonable scheme a few years ago for implementing these efficiently in both time and space: Google Scholar page: http://scholar.google.com/scholar?cluster=13915175648622039304&hl=en&as_sdt… Slides: https://fs.hlrs.de/projects/eurompi2010/TALKS/TUESDAY_MORNING_TRACK1/Compac… I can't quickly find an electronic copy to which I actually have access, though I think I have one in dead-tree form in my office. The MPICH group code is pretty horrible right now. But it's not a heavily used piece of the implementation, so it's usually been hard to justify improving/fixing it. -Dave

Re: [mpich-devel] memory profiling HOWTO?

There are two kinds of memory that MPICH with ch3:nemesis allocates: 1) regular heap memory via malloc (with interposition possible via MPIU_Malloc and friends) 2) shared memory via one of the usual mechanisms (mmap, shm_open, etc.) You can determine the current amount of #1 by calling "MPIU_trspace" as long as you configure with "--enable-g=mem" (or some superset thereof). You'll get some additional performance overhead when allocating/freeing memory if you configure this way, since MPICH is doing some additional allocation and bookkeeping in order to track this information for you. If you need a lower overhead method for doing this, you'll need to modify/intercept MPIU_Malloc and friends yourself. You'll need an "extern" declaration for "MPIU_trspace" in order to call it from your test program. You can use the attached (untested against HEAD) patch to give you a hook for #2. You'll need to throw down an "extern" declaration for the routine in your test program as well. -Dave On Feb 22, 2013, at 9:28 AM CST, Jim Dinan wrote: > Jeff, > > Which memory are you interested in -- memory the application allocates, or memory that MPICH allocates?

is sublinear memory usage in MPIR_Group_create (and related ops) possible?
by Jeff Hammond 22 Feb '13

I see this error on BGQ at scale (nproc=524288). Abort(1) on node 492082 (rank 492082 in comm 1140850688): Fatal error in PMPI_Comm_group: Other MPI error, error stack: PMPI_Comm_group(174)....: MPI_Comm_group(MPI_COMM_WORLD, group=0x1fffffb9b4) failed MPIR_Comm_group_impl(45): MPIR_Group_create(83)...: Unable to allocate 8388608 bytes of memory for newgroup->lrank_to_lpid (probably out of memory) The culprit appears to be (*new_group_ptr)->lrank_to_lpid = (MPID_Group_pmap_t *)MPIU_Malloc( nproc * sizeof(MPID_Group_pmap_t) ); and typedef struct MPID_Group_pmap_t { int lrank; /* Local rank in group (between 0 and size-1) */ int lpid; /* local process id, from VCONN */ int next_lpid; /* Index of next lpid (in lpid order) */ int flag; /* marker, used to implement group operations */ } MPID_Group_pmap_t; I haven't thought about it very deeply yet, but is there a way to implement group operations without using O(p) memory?

Jeff, Which memory are you interested in -- memory the application allocates, or memory that MPICH allocates? If the former, you can use the PMPI interface to hook MPI_Alloc/Free_mem. If you are interested in MPICH internal memory use, Dave can probably give the most informed answer. I would probably just modify MPIU_Malloc. ~Jim.

memory profiling HOWTO?
by Jeff Hammond 22 Feb '13

22 Feb '13

Is there any documentation of how to properly instrument MPICH with memory profiling? I understand MPIU_MALLOC allows me to do this. My goal is to merely print out every time memory is allocated larger than a particular size. I'd also like the rank to show up in the output. Please RTM me if the M exists. Source comments are also a good M if they are correct and sufficiently complete. Thanks!

unistd.h is not part of C - it is for Unix and Unix-like systems. There is a test for this file in configure.ac that should be used, and the Unixism in the test should be removed or protected. The test programs should not assume Unix/POSIX/Linux. The other fixes look good.

patch for missing declarations in test suite

I'm submitting this via email because Trac is hosed right now (I assume it will be fixed in a few hours, but I don't want to enqueue this in my head that long). LLVM complained about use of undeclared functions being invalid in C99. I fixed them in the attached patch, which is copied below.
