Hi again,I just double checked the test invocations of INMF which are on /much/ larger matrices with /far/ more iterations and am still seeing zero seconds. That /is/ a bug, but its not a related one. The objective error of 44244.4 is what it should be returning for the example matrices.
I just benchmarked devtools::check() (which is actually a build followed by a check) on my Ryzen 5700X/intel 660p system with a bunch of stuff going on in the background and got just over 11 minutes. I don't actually think its timing out. No output differences, of course.
If you could get me more information (perhaps off-list) about the -lstdc++ thing I'm curious about reproducing that.
Best. -Andrew Robbins On 12/7/2023 5:45 AM, Ivan Krylov wrote:

(On my Linux machine, I had to crudely hack in linking with -lstdc++fs because some of the dependencies of RcppPlanc.so didn't pick it up automatically.)and hangs/is killed on initiation of INMF res2 before the initialization of RcppProgress.Can we eliminate it running out of time? On my Windows 10 LTSC machine (AMD Ryzen 5 2400G from 2018, SATA SSD, nothing else going on at the time) the complete R CMD check takes slightly more than 10.5 minutes. An R-release check running on an Intel Xeon E5-2680 from 2016 with other checks going on at the same time could plausibly take more than 20 minutes and get terminated [1], with some of the buffered output never reaching the RcppPlanc-Ex.Rout file... but then it happens on a much faster R-devel checking machine [2], which runs on an AMD EPYC 7443, and we never see any differences in the output. Right?
