Hi Jasmina,
I have a question about the generator. I use lt like this:
$ ./rmat --name RMAT20_dir --scale 20 --edges 16777216 Generator type: R-MAT Scale: 20 (1048576 vertices) Edges: 16777216 Probabilities: A=0.57, B=0.19, C=0.19, D=0.05 Generation time: 4.807255s
but it has a error.
`$ ./bfs_simple -n 1048576 -f ../zhangyangData/RMAT20_dir -t 64 -w
P = 409
#Running with 64 update threads and 64 algo threads

Do you have any advise how I can fix my problem?

Thanks in advance

Hi Jasmina,
My name is yang zhang,and I am currently studying computer science major in information engineering and technical college of hunan university.I have read the abstract of your paper entitled "Everything you always wanted to know about multicore graph processing but were afraid to ask".I'm so interested in the content of your paper that I want to redo a series of experiments related to the paper.But I have a question about the input file format.I have a lot of data in MTX format,and I want to convert it to binary format.What program did you use to convert? Did you write it by yourself?

infinite loop when running: (https://github.com/epfl-labos/EverythingGraph/blob/f2ac1309725fd795f169983a1f6b6e492c4b3991/bfsgrid_cilk.c#L129)

./bin/bfsgrid_cilk -n 4847571 -m 1 -f /data/soc-LiveJournal1.bin

Need Help

Could you please download my code base and re-run it, figure it out whether there is the same problem or not?

• Maybe I use the wrong data file type?
• Maybe I type the wrong command?

hi, there

I have trouble in generating a file of the desired format as input graph. Is there any tool or example input file that I can take a look?

//Updates

I finally get it to run.

Line 814 in init_all.c looks like a bug :). The die function also does not work as expected, it did not exit here in my case.

Thanks,

Wei
