Using GitHub's new projects tool.
Run make
from src
directory.
Can be generated using the included graph_gen
binary:
$ cd data
$ ../bin/graph_gen 65500 9825000 | ../bin/graph_gen > g_65500_9825000
$ cd ../src
$ split ../data/g_65500_9825000 -n l/3 # should create xaa, xab, xac
- Currently only supports Linux x86_64 platform.
- Needs a lot more testing.
- Increasing
NVERTEX
to over 65536 on my test machine results in an unresponsive system depending on system load. - It is wise to enable Linux sysrq key combinations during testing. In case of a hang, I can kill the most expensive process (careful, could be chrome or any other important process) using
Alt
+SysReq
+F
. - The problem described in last two points can exacerbate if debugging options like the following are enabled in
Makefile
:Address Sanitizer, specifically, will spawn its own threads further affecting system load.DFLAGS = -fsanitize=address -g -D_GLIBCXX_DEBUG
