I tried all your suggestions and changed the code but it still doesn't work
and it behaves strange. For example, different runs of program give
different results because data is not transferred correctly. But cores that
return wrong result are different for every run and it looks like it's
random. Also, number of cores with correct result and correct data aren't
always equal. There is no difference between busy wait and sleep(1) - same
random things happen.
I checked *.srec file and nothing is written on addresses I'm using. I'm
not succeeding in finding a mistake and I can't figure out what is causing
this behaviour.
Something like this happens every time I make changes to working
implementation and I've tried lot of things to make it work but usually
every try fails. What can cause this type of behaviour? Am I very wrong in
my approach because this is taking lot of my time and things that are
happening don't make much sense?

Thank you

Katja

/*
 * There was a sign extension bug in older revisions of this function.  While
 * we would have liked to simply fix the bug and move on, we have to provide
 * a backwards compatibility feature (essentially the bug) for some systems and
 * a safety measure for some others.  The latter is needed because for certain
 * multiple inputs to the buggy algorithm there exist easily found inputs to
 * the correct algorithm that produce the same hash.  Thus, we optionally
 * deviate from the correct algorithm just enough to avoid such collisions.
 * While the bug itself affected the majority of passwords containing
 * characters with the 8th bit set (although only a percentage of those in a
 * collision-producing way), the anti-collision safety measure affects
 * only a subset of passwords containing the '\xff' character (not even all of
 * those passwords, just some of them).  This character is not found in valid
 * UTF-8 sequences and is rarely used in popular 8-bit character encodings.
 * Thus, the safety measure is unlikely to cause much annoyance, and is a
 * reasonable tradeoff to use when authenticating against existing hashes that
 * are not reliably known to have been computed with the correct algorithm.
 *
 * We use an approach that tries to minimize side-channel leaks of password
 * information - that is, we mostly use fixed-cost bitwise operations instead
 * of branches or table lookups.  (One conditional branch based on password
 * length remains.  It is not part of the bug aftermath, though, and is
 * difficult and possibly unreasonable to avoid given the use of C strings by
 * the caller, which results in similar timing leaks anyway.)
 *
 * For actual implementation, we set an array index in the variable "bug"
 * (0 means no bug, 1 means sign extension bug emulation) and a flag in the
 * variable "safety" (bit 16 is set when the safety measure is requested).
 * Valid combinations of settings are:
 *
