Description Noticed this while using libSVM in sklearn - training an SVM when cache_size > 2000 or so on large problems does not seem to lead to any benefit/speed up. Looking at RAM usage, it shows that usage is still about 200MB (which ...
size = max(size, 2 * (long int) l); // cache must be large enough for two columns lru_head.next = lru_head.prev = &lru_head; } 该函数根据实参:样本数L,申请L个head_t的空间,初始化为0;size的处理是:先将输入的size值(byte单位)转化为float的数目,然后再减去L个head_t所占的空间;其中...
In other recent SVM systems such as TreadMarks, CVM, and Quarks, the shared address space is limited by the size of the memory of a computer. In JIAJIA, the size of shared space can be as large as the sum of each machine's local memories. ffl A lock-based cache coherence protocol ...
