wrong number of iterations #4

Besides, some graphs will be divided into 0 shards. I am not sure what's wrong with my set up. |
The simplest execution of CuSha in Ubuntu 14.04 with |
Thanks for your response. I ran Cusha under Ubuntu 14.04 with CUDA 7.0. I also got 789 shards, while only 1 iteration was performed. I also ran belgium_osm and road_usa, which turned out to be 0 shards. This is how I ran Cusha
I downloaded the the datasets from |
Please start with the simplest algorithm (BFS) by un-commenting the corresponding line in |
Thanks for your kind help. And sorry that I didn't express well. The second step is optional, I only preprocess for PageRank application, and of course use the generated file as the input for Cusha. And I have tried all SSSP, PageRank and BFS. Unfortunately, none of them return expected answer. BFS application also gives me 1 iteration and 789 shards for soc-LiveJournal, and 0 shard for Belgium_osm and road_usa. |
Have you tried running with a different |
That's it! After I changed arbparam to 2 or 3, it returned correct result. For Belgium_osm and road_usa, I just found I forgot to set the paramater to undirected. Many thanks for your help! |
I tested Cusha on LiveJournal dataset, finding only 1 iteration performed. PR, BFS and SSSP all had this issue. Is that a problem of wrong input format?I used edgelist as the input. Thanks!
