This addition facilitates the communication between the threads belonging to the same processor, not having to use the low speed global memory
when sharing small amounts of data.
As mentioned above, GPUs have a local memory region to store local data for a CU, and its access time is much faster than that of the global memory
The method obtains a slightly better behavior than CSR-vector by padding rows with zeros to increase data regularity, using parallel reduction techniques, and prefetching data to hide global memory
Threads may access a few kinds of GPU memory: global memory
(big latency, read-write), shared memory (on-chip, low latency, limited to 16/48kB per block), texture memory (low latency, read-only), and registers (low latency).
Data parallel languages are usually implemented on shared memory architectures because the global memory
space greatly simplifies the writing of compilers.
Unfortunately, Samsung is trimming its investment plans in memory this year and has postponed capital spending on its US factory because of the worsening global memory
Qimonda AG (NYSE: QI) is a leading global memory
supplier with a broad diversified DRAM product portfolio.
Small-scale studies looking at hormonal intervention in women following a surgical menopause showed that those randomly assigned to hormone therapy maintain their scores on short-term global memory
tasks compared to those assigned to placebo.
Instead of splitting memory between multiple CPUs a large global memory
is available which is accessible by both (or all) of the processor cores.
The way that Google has entered our lives indicates how profoundly reliant we are on an infinitely deep and infinitely accessible global memory
, not solely on our personal ones.
Thus global memory
consumption can also be a subordinate production, one that creatively and tactically resists the homogenizing tendency of centralized systems.
Through this, the AHPCRC is also supporting the Defense Science Board's Task Force on Supercomputing recommendation related to the development and acquisition of high-end computing systems with improved processor to global memory
latency and bandwidth for critical defense applications.
