(hardware) errors during generation and compression.

Verifies consistency of KQRvKR.rtbw and KQRvKR.rtbz. Not needed on systems with 24 GB RAM or more. Generate 6-piece tables on systems with 16 GB RAM. Statistics are written to $RTBSTATSDIR/KQRvKR.txt Generate the table but do not compress and save. Only compress and save the DTZ file (with. Only compress and save the WDL file (with. Set n to the number of CPU cores, or if the CPU supports hyperthreading, If no other tasks are running, it is recommended to Produces two compressed files: KQRvKR.rtbw and KQRvKR.rtbz. However, correct md5sums are known as well, and these can also be used to verify integrity. Note 1: Since a correct set of checksums is known, there is no need for anyone to run rtbver and rtbverp.

tbcheck for verifying integrity of tablebase files based on an embedded.

rtbverp for verifying pawnful tablebases.

rtbver for verifying pawnless tablebases.

rtbgenp for generating pawnful tablebases.

rtbgen for generating pawnless tablebases.

If your CPU does not support the popcnt instruction, the line FLAGS += -DUSE_POPCNT should be commented out. It might be necessary to edit src/Makefile. It should beД®asy to build on x86-64 Linux system and on 64-bit Windows with MinGW

The directory src/ contains the tablebase generator code. The DTZ tables take up 81.9 GB.ДЇor up to 5 pieces, the numbers are 378 MB and 561 MB. The 6-piece WDL tables are 68.2 GB in total. These files only need to be accessed when the root rtbz files store the distance-to-zero: the number of moves to the nextД¬apture or pawn move.

These files are 'two-sided': they store information for both

rtbw files store win/draw/loss information including, where applicable, Note that KRPvKR also covers K+R vs K+R+P.

Sufficiently recent gcc (producing 64-bit executables).ДЇile names encode the type of tablebase: K+R+P vs K+R becomes KRPvKR.Д®ach tablebase corresponds to two files: KRPvKR.rtbw and KRPvKR.rtbz.

16 GB of RAM for 6-piece tables (much less for 5-piece tables).

The tablebase generator is able to generate
