Using graphs from LDBC about gapbs

[sbeamer]

The issue appears to be the LBDC format uses floating point weights. Much of the gapbs code is templated, so changing a typedef (WeightT) in one spot (src/benchmark.h) will suffice for your case.

However, I would be careful with using floating point weights for multiple reasons. First, although the modification described above will suffice for loading in these LBDC graphs, it will not be able to write it out as a .wsg because the .wsg format uses integer weights. The kernels can load graphs in whatever formats gapbs supports, and the use of the serialized formats (.sg or .wsg) is for speed on the biggest graphs. Second, floating point weights can cause problems for graph algorithm developers not accustomed to floating point arithmetic.

For more input graphs, I strongly recommend SuiteSparse or SNAP. We have also tried to list other sites we are aware of.

Thank you a lot @sbeamer! I finally managed to get some new graph inputs running with the kernels provided in GAP. As we solved that one, I will close it.

Thanks again 😄
