There is also a known segfault around reloaded CSA graphs: csa_invoke(graph1,…) csa_invoke(graph2,…) This bug is fixed in the next release.

To give an idea of timeline - I would hope they have been completely removed from the examples, architecture doc., and simulator by early to mid October. (We know they are not going to be there, and there is no point putting effort into dealing with them.)

The API between the memory model and the functional simulator was modified to support streaming loads/stores, and I haven’t gotten around to updating the code for wide loads/stores.

The same graph runs fine without memory model. An example is below, where I can easily get around the segfault by using a sequence of loads. ld64x bi_addr, bondlist, i #ld32x8 i1, i2, type, %na, %na, %na, %na, %na, bi_addr ld32x i1, bi_addr, 0 ld32x i2, bi_addr, 1 ld32x type, bi_addr, 2 This is with a graph written for LAMMPS. I tried reproducing in one of the examples in ${CSASIM_TOP}/example, but that resulted in different crash… The example 059-multivalue-mem runs fine for me without memory model, but crashes with “one or more LICS not empty on exit” with memory model activated. chris ====================== Using simple memory model *** Error in `/home/knightc/projects/csa/lammps-31Mar2017/src/lmp_jlse_csa': free():
