FERN: Fast Explicit Reaction Networks SVNCode

Corrected initial value of sumXLast to sum over actual mass fractions rather than 1. This seems to have been distorting the initial timestep correction versus the Java code. Now the first two timesteps give the same dt for CUDA and Java codes.

Print buffer size increased by factor of 10 over default in line 1064 to get all the diagnostic printf stuff from the gpu output. Only the last several lines are output if the default buffer size is used.

Testing

Double precision program now compiling and running. Checking results.

Attempting to compile double precision version. Found that in sscanf readin all formats %f have to be converted to %lf, otherwise all floating point read in will be zero.

Double precision version of cuda network after all initial changes made

Double precision version of cuda network after all float types converted to double type
