TPC (Texture Processor Cluster,纹理处理簇),每个TPC包含Poly Morph Engine和多个SM。 SM (Streaming Multiprocessors,流多处理器),包含多个SP(或称CUDA Core)负责线程执行。 Memory Controller为内存控制器,负责访问显存。 Memcoy为GPU显存。 High Speed Hub为高速集线器,负责GPU间的内存访问。 NVLink为GPU间的高速...
前面介绍启动governor时中注册了调频函数dbs_update_util_handler,下面分析一下调频流程 //driver/cpufreq/cpufreq_governor.c dbs_update_util_handler irq_work_queue(&policy_dbs->irq_work);//init_irq_work(&policy_dbs->irq_work, dbs_irq_work); schedule_work_on(smp_processor_id(), &policy_dbs-...

Looking for your best next computer processor or just want to compare GPUs head to head? GPU-Benchmark is the best GPU compare tool in the world trusted by millions of users, help you find out which one is better and see the differents.
Speed Centric会保留计算出的tensor以备后续使用; Memory Centric会在计算完成后释放tensor,需要时再重新计算; Cost Aware会在计算完成后判断是否保留tensor,若可能导致内存峰值则释放。 可以将swap和recompute结合使用,针对特定op采用不同方式。还可以预先迭代几次,收集内存和运行时间信息,判断哪些tensor该swap,哪些该re...

对于同构多核处理器(Homogeneous Multicore Processor),需要理解的层级概念可以简单罗列为以下几部分(由高级到低级): application software layer:app1,app2,app3…… infrastructure layer:host operating system physical hardware layer:每个core有计算单元,L1 cache(instruction-cache,data-cache),L2 cache。多个core可...
GPUs Speed Up Your System From the user’s perspective, all the applications run smoothly and much faster as there are two units performing two different tasks. The new term ‘General Purpose Computing Graphics Processing Units’ (GPGPU), which is nothing but GPUs assisting the CPU in general-...
手机芯片系列先到这里,接下来看看作为独立卡使用的 NPU 系列。04路线二:NPU 用作推理/训练芯片(Ascend AI Processor) 两个产品:301 低功耗;910 高算力。 设计见 paper [2]。 产品:加速卡 Atlas 系列 型号Atlas 200/300/500/…,包括了 NPU 在内的 SoC,用于 AI 推理和训练。
