Hi,

We failed to enable a communication between sender and receiver on different machines. It seems MS APSI does not support the related issue.

We have tried to specify the receiver machine's ip address in sender machine's sender.cpp file, with the following modified code:

int remote_query(const CLP &cmd)
{
    APSU_LOG_INFO(__FILE__ << __LINE__);
    auto SenderKKRTSocket = coproto::asioConnect("<host_R_ipAddr>:1212",false);
    APSU_LOG_INFO(__FILE__ << __LINE__);

where <host_R_ipAddr> is receiver machine's IP.

Then we rebuilded the project, started receiver machine listening at <host_R_ipAddr>:1212, and next started sender's query. Unfortunately, both machines stuck there and returned no communication information.

PS: we have successfully tested localhost case via two opening terminals with cli.

Hi! I encountered an issue where the receiver side reported the failure indicated by a message about the inability to insert parameters into the cuckoo table.

Successful Test Cases:
(2^18, 2^10, 16M-1024.json)
(2^16, 2^10, 16M-1024.json)

Failing Test Case:
(2^16, 2^12, 16M-1024.json)
(2^18, 2^12, 16M-1024.json)
(2^16, 2^16, 16M-1024.json)
(2^18, 2^16, 16M-1024.json)
(2^20, 2^20, 16M-1024.json)

This issue arises consistently in different balanced/unbalanced dataset settings with the configuration 16M-1024.json.

As I did not find explicit illustration about tuning with JSON parameters, could you please provide more guidance on this matter?

Best wishes and happy new year!

Hi,

I have compiled the project successfully with all required dependencies. The compiler version is g++-10, with a python version 3.10.

Then I followed auto-test.py, and tried to set connections via the subprocesses. However, it reported an error "Segmentation fault (core dumped)" at sender process side, and an error "Failed to create ReceiverDB: Connection reset by peer; Failed to create ReceiverDB: terminating" at the receiver side.

This happened in both running the two cli in a single python script (i.e. run the file /tools/auto-test.py), and in two separate windows.

The detailed error logs are as follows, from a two-separate-running-window case:

PS: the issue happened when using the two same ports, or two different ports.

Do you have any suggestions for running a successful 2^10 vs. 2^18 -sized PSU case?

Looking forward to your reply : )

您好，我只在代码中看到了OSN洗牌算法。我想知道20亚密中的那个洗牌算法是否没有在代码中实现。感谢您的帮助！
