Hi I have i7 with 16GB memory, clean 64-bit Ubuntu install All 5 men tbs generate quickly I get the following: rtbgen KQRvKRR -d Found 145 tablebases. number of threads = 1 Could not allocate sufficient memory. Any chance?

Read the readme.md. You need to use the -d flag with 16GB. If you had 24GB ram , -d flag is not needed. Obviously using the -d flag will slow the generation down. I created all 6 man using a 12 core Mac Pro with 32 GB ram. Roughly 72 hours.

Edit : I now see you did use the -d flag , I’m not sure why it failed.

Thanks for the answer. I did use -d I went down to one thread too Can it be that swap is too small?
