问题描述

moe 算子开启numa功能， alloc和free 不一致，导致free 失效oom

deepseek R1 模型， moe算子，free时候，计算free size时候，超过int32 表示范围，导致free失效，numa内存没有回收，导致oom

fix patch
MOE::~MOE() {
shared_mem_buffer.dealloc(this);

#ifdef USE_NUMA
int numa_nodes = numa_num_configured_nodes();

for (int i = 0; i < numa_nodes; i++) {
    size_t exp_inter_hidden_mul_ = (size_t)config_.expert_num * config_.intermediate_size * config_.hidden_size;
    numa_free(gate_proj_numa_[i], exp_inter_hidden_mul_ * ggml_type_size(config_.gate_type) / ggml_blck_size(config_.gate_type));
    numa_free(up_proj_numa_[i], exp_inter_hidden_mul_ * ggml_type_size(config_.up_type) / ggml_blck_size(config_.up_type));
    numa_free(down_proj_numa_[i], exp_inter_hidden_mul_ * ggml_type_size(config_.down_type) / ggml_blck_size(config_.down_type));
}
#endif

}
