v1.2.2

• Deleted unneeded library "cufft"

v1.2.1

• Added "train_set" file. A large dataset to observe the speedups between CPU and GPU execution times.

v1.2

Using LibSVM 3.17 & CUDA SDK 5.5

• Exchanged the header file “cublas.h” for “cublas_v2.h”.
• Exchanged the type cublasStatus for cublasStatus_t.
• Exchanged the function cublasAlloc() and cublasFree() for cudaMalloc() and cudaFree(), respectively.
• Declared the cublasHandle_t CUBLAS library handle.
• Initialized the handle using cublasCreate(). Also, released the handle once finished using cublasDestroy().
• Added the handle as the first parameter to all the CUBLAS library function calls.
• Changed the scalar parameters to be passed by reference, instead of by value (usually simply adding “&” symbol in C/C++ is enough, because the parameters are passed by reference on the host by default).
• Changed the parameter characters 'N' or 'n' (non-transpose operation), to CUBLAS_OP_N.
• Checked the function prototypes in the header files “cublas.h” and “cublas_v2.h” for code correctness.
