Unable to Execute on cloudlab node: r650 or r6525 (with ConnectX-5 network cards)

[J-XZ]

Issue 1:

NovaLSM/novalsm/nova_server_main.cpp

Line 235 in 8a66119

NovaConfig::config->max_stoc_file_size = FLAGS_max_stoc_file_size_mb * 1024;

Is it necessary to modify here to * 1024 twice, rather than once?

Issue 2:
Can this project run on CloudLab nodes with updated versions of RDMA network cards, such as r650 or r6525 (using ConnectX-5 network cards)? I attempted to run this project on a cluster composed of five nodes, where the commands executed on each of the five nodes were as follows:

The objective is to use node0 and node1 as ltc, node2 as stoc, and node3 and node4 as clients. Am I correct in my understanding of the commands? Additionally, when I run in the manner described above, node0 encounters a segmentation fault. The error occurred possibly during the execution of the first flush or compaction, after successfully inserting approximately 16348 key-value pairs. The error location is at

NovaLSM/rdma/nova_rdma_rc_broker.cpp

Line 252 in 8a66119

NOVA_ASSERT(wcs_[i].status == IBV_WC_SUCCESS)

where the value of wcs_[i].status is IBV_WC_RETRY_EXC_ERR. Does this imply that RDMA is not properly configured?

Thank you for your time and assistance.
