Encounter an error when running the GPU version of FSM in Pangolin #3

Closed hlj2546 closed 2 years ago

After running make in /src/pangolin/fsm, encounter an error when running ./bin/pangolin/./fsm_base ./inputs/citeseer/graph 3 100 as the tips. The running details are as follows:

max_size = 3 min_support = 100 Number of unique labels: 6 |V| 3312 |E| 9072 Found 1 devices Device[0]: NVIDIA GeForce GTX 1080 Ti Compute capability: 6.1 Warp size: 32 Total # SM: 28 Total # CUDA cores: 3584 Total amount of shared memory per block: 49152 bytes Total # registers per block: 65536 Total amount of constant memory: 65536 bytes Total global memory: 10.9 GB Memory Clock Rate: 5.25 GHz Memory Bus Width: 352 bits Peak Memory Bandwidth: 484.44 GB/s

error 1: Cuda error in file '../../../include/pangolin_gpu/../graph_gpu.h' in line 108 : invalid argument.

which corresponds to CUDA_SAFE_CALL(cudaMemcpy(d_labels_frequency, hg.get_label_freq_ptr(), (num_vertex_classes+1) * sizeof(vidType), cudaMemcpyHostToDevice)); after reading the source code, I found that the use of hg.get_label_freq_ptr() after labels_frequency_.clear(); may be the cause of the problem. But I have no idea how to modify it to make the program run properly. Could you help me to solve this problem? Best regards.
