Possible issue of the function compile_pseudo_pop running on a Linux machine / Ubuntu 22.04.2 LTS

[andrepython]

When running the function compile_pseudo_pop on my Linux server, it generates an error message 'Aborted (core dumped)'. However, the same code works on my Windows 10 machine. I am not sure what is the cause of the issue but I suspect that this occurs during the parallelization process (perhaps issue on the nthread argument / number of cores attributed?).

I use R 4.3.0, Platform: x86_64-pc-linux-gnu (64-bit), CausalGPS ‘0.4.1’, and Ubuntu 22.04.2 LTS. I have attached a zip file that contains files with more details about the specifications of my server (machine_info.txt), R code and output (Rcode_and_Routput.txt), and data input (ACLED_1_type.Rdata) here:

Many thanks for your support!
Best wishes,

I have just found that if I decrease the number of DT threads as follows: data.table::setDTthreads(percent=30) before running the function compile_pseudo_pop, it seems to solve the issue. But percentages higher than 45% seems to lead to the issue previously reported. Perhaps one should further investigate how the function compile_pseudo_pop allocates cores for parallel processes on a Linux machine with particular specification such as mine (AMD Epyc 7713 dual core, 64 x 2 physical cores, 128 x 2 logical cores).
