Ok, I believe I have 2 files ready to upload; tomorrow will try. Will also check
-- can I again gain the access to the large Alphas?

Actually, main thing to do is to modify the generator to:
(1) Handle general pawnless kxykuv, not only the kxykzz. Here 32 bits are not
enough, so I'll have to produce those on 64 bit systems (Alphas or Itaniums),
otherwise generator would die trying to perform 64-bit arithmetics on x86.
(2) Handle TBs that are "sliced" into chunks -- even compressed pawnless kxykuv
will be larger than 2Gb. Compression routines cannot handle such files, as well
as some free operating systems :-).
(3) Handle 6-man TBs with pawns. I have code donated by Peter Karrer, and with
his code generator would produce 48 smaller files instead of large one - i.e.
kqpa2kqp, kqpb2kqp, ..., kqph7kqp. I have to merge that code into current
version of the generator, but after that TBs with pawns can be produced on a
128Mb machine with 512Mb of free disk space. Good job for your Xeons.

Main problem is lack of time -- we are very busy now, as Itanium release is
approaching...
