the lookup tool is being worked on. with the latest changes in table layout there have come up some extra issues. and you wouldnt want a lookup tool that crashes regularly. > I dont know where to start.The lookup is a kind of recomputing lines of the > table in order to retrieve the initial state.Does anybody know if it is > possible to reuse the initial computing tool in order to lookup in the table? > Is it at least possible to reuse some methods of the code in order to perform > the lookup?My problem is that i have no idea of how to develop things for > CUDA stuff.

You could in theory use the generator, but you would have to write a bunch of shell scripts to use it correctly and it would take ages to do a lookup. Its not really an option. All A5/1 computations are executed on the CUDA device during lookup. > Another question is that, since we change the reduction function for each > distingushing point, does the first message sample used to lookup have to be > a distinguising point?If yes that would mean that the probability of success > would be decrease since we are not sure to get access to a 64bits sample that > is a DP. > Thanks for the helpCheersSylvain > The lookup data does not have to be a DP. When you do a lookup the chain that you build must merge with a chain in the table for the lookup to be successful. The merge has to happen in the very first step of the computation or else you will not find a chain in the table that leads up to your data point. So you have to find a merge but it can be anywhere in the table, for the 2 chains to merge and produce the same end value. _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
