FlashGraph el2fg converter hangs with wiki-Vote dataset #408
Description
Hi FlashX Team,
I am deploying the FlashGraph standalone right now according to your wiki
However, when I convert a graph in edge list format to the FlashGraph format, the el2fg hangs with the wiki-Vote dataset
$ # from the top dir of FlashX
$ wget http://snap.stanford.edu/data/wiki-Vote.txt.gz
$ gunzip wiki-Vote.txt.gz
Then, I delete beginning lines of data descriptions
Next, I try the following command and el2fg hangs
$ ./build/flash-graph/utils/el2fg flash-graph/conf/run_test.txt wiki-Vote.txt wiki-Vote
Subsequently, since that the delim of wiki-Vote is tab, I also try another command below
$ ./build/flash-graph/utils/el2fg flash-graph/conf/run_test.txt wiki-Vote.txt wiki-Vote -d "\t"
The output of these two commands is same:
Initialize ops. There are 11 types
read edges from 1 files
SAFS runs on 2 NUMA nodes
The root conf file: FG_TOP/flash-graph/conf/data_files.txt
FG_TOP/flash-graph/conf/data_files.txt doesn't exist
FlashMatrix: fail to initialize SAFS
FlashMatrix runs on 0 threads and 2 NUMA nodes
reserved 0 bytes are associated with NUMA nodes and 0 bytes aren't
sort buf size: 1073741824, groupby buf size: 1073741824
start to read and parse edge list
(ends and hangs here)
Unfortunately, none of these commands work when running the el2fg converter. BTW, I didn't set the FG_TOP because I would like to run FlashGraph standalone first.
It would be appreciated if you could give some helps for this issue, Thanks.
