根据中国剩余定理的同构性质, Rt 上多项式的加法和乘法分别等价于向量对应元素的加法(point-wise addition,逐点加法)和乘法(point-wise multiplication,逐点乘法)。因此,SIMD 编码实现了同态加法和同态乘法的并行化。由于 FHE 系统的参数设置使得 SIMD 编码的向量维度较大,通常为 65536,这就赋予了第二代 FHE 极高的...

CLMUL指令执行的是Carry-less multiplication(无进位乘)操作,实际上做的是复杂的二进制多项式乘法。CLMUL也分为SSE版本和AVX版本各1条,分为:PCLMULQDQ(SSE版本)以及VPCLMULQDQ(AVX版本)。CLMUL类似于AES-NI指令在加密、解密方面得到广泛的应用。 XOP指令的特色 ...
Right now the matrices are small, and if that stays the same don't mind this point, but if you think they're going to get larger you may want to look into tiling the multiplication - this will have much better caching behavior than a large row-major x row-major multiplication. ...
Matrix multiplication is one of the most common numerical operations, especially in the area of dense linear algebra, where it forms the core of many impor... J Kurzak,W Alvaro,J Dongarra - 《Parallel Computing》 被引量: 120发表: 2009年 Efficient Matrix Multiplication on SIMD Computers Efficie...
Matrix-Vector Multiplication Functions func simd_mul(simd_double3, simd_double3x3) -> simd_double3 Returns the product of a three-element vector and a 3 x 3 matrix. func matrix_multiply(simd_double3, simd_double3x3) -> simd_double3 Returns the product of a three-element vector and a 3...
If we take a closer look in the scalar multiplication process, we can see that we can calculate the whole vector at once: In the scalar code, Vec.x is multiplied with the first four elements of the matrix. Those four elements are represented as the first line of the matrix, and are ...
