Precooking random seeds for U4Random

[ggalgoczi]

./opticks/qudarap/tests/rng_sequence.sh run should load/create the random numbers that we need but it relies on QSim/QSimTest

QSim::rng_sequence function precooks the seeds that we need to have in order to use the same random numbers on GPU and Geant4. I tried to compile the QSimTest using opticks/qudarap/tests/CMakeLists.txt but got some errors.

Could you take a look at this @plexoos ?

Created random numbers by adding the following code to opticks/g4cx/G4CXOpticks.cc

unsigned ni = 1000000;
int ni_tranche_size_ = 100000;
unsigned nj = 16 ;
unsigned nk = 16 ;
unsigned ni_tranche_size = ni_tranche_size_ > 0 ? ni_tranche_size_ : ni ;
const char* udir = "$HOME/.opticks/precooked/QSimTest/rng_sequence";
qsg->rng_sequence(udir, ni, nj, nk, ni_tranche_size, false );

Will add this code to our fork of Opticks. However when trying to use these random numbers in simg4ox I get:

simg4ox: /esi/opticks/u4/U4Random.cc:607: virtual void U4Random::flatArray(int, double*): Assertion `0' failed.
