failure running splitAndBalanceMesh on large mixed mesh

[cwsmith]

After splitting, during hypergraph creation (mesh elements are graph nodes, mesh vertices -> hyperedges), the pin connection process segfaults with the a bad allocation here:

EnGPar/interfaces/apfGraph.cpp

Line 293 in 6885371

lid_t* pl = pin_list[type] = new lid_t[nlp];

The following print statement was added before that line to help determine the cause:

fprintf(stderr, "%d nlp %d nle %d\n", PCU_Comm_Self(), nlp, nle);

The output from a run on Pleiades is pasted below. Two ranks print large negative values for nlp:

57 nlp -1146837624 nle 51071
56 nlp -841074879 nle 52681

[diamog]

My first intuition is telling me the problem is an integer overflow. This line is what is troubling me along with the negatives:
101 nlp 1915291810 nle 49541

With the 55% vertex imbalance, I am assuming there are a few parts with a lot of vertices and those vertices are bounding a lot of elements (likely made worse by the mixed elements).

You can try running with the local id type as a 64-bit int and see if that fixes the problem.

[KennethEJansen]

I would expect this on the target case (278M verts) but this case is only 8M verts so this would be surprising. I will see if I can figure out how to rebuild the code with 64 bit int.

[KennethEJansen]

-DMDS_SET_MAX=1024
-DMDS_ID_TYPE=long \

robbed these from chef....is either of these what I am looking for?

[KennethEJansen]

Hacking around I think I found the right flag:

[KennethEJansen]

yep. Hard to imagine that this is not a bug. How does an 8M node mesh blow out of 64 bit ints.

[KennethEJansen]

I will see if I can get this built with memory sanitizer on the viz nodes and see if I can make it fail going from 8 to 16 parts.

mpirun noticed that process rank 7 with PID 14126 on node viz003 exited on signal 6 (Aborted).

This was with memory sanitizer and it is not reporting any issues

[KennethEJansen]

And the tiny case also crashes going from 1 to 2

I did some sanity checks and did not find anything. Can I get a copy of the smallest failing case so that I can explore the issue further?

Hopefully Cameron can transfer the files to a machine you have access to.

This has become non-urgent but still interesting because I have improved (fixed bug in weight setting) of chef and am now able to get 9% node imbalance from chef with graph partitioning out to 16320 processes.
