If that requested data is fetched means, then no need main memory
. Then the given data will directly processed to the processor.
In a case of miss being recorded in L2, the request passed to main memory
and the L1 and L2 are updated.
In other words, CPUs and GPUs fetch data from off-chip main memory
at approximately the same speed, but GPUs can execute the functions that use that data more quickly.
The Exalytics Intelligence Machine Ellison introduced will run Oracle's Times Ten and Essbase databases, both gained through past acquisitions, in its terabyte of main memory
. The system analyses business data many times faster than on machines that store information on disk drives, Ellison told customers at the company's OpenWorld event.
By using two floating gates, the device can store a bit in a nonvolatile mode, and/or it can store a bit in a fast, volatile mode - like the normal main memory
on your computer."
Existing nonvolatile memory used in data storage devices utilizes a single floating gate, which stores charge in the floating gate to signify a 1 or 0 in the device - or one bit of information.By using two floating gates, the device can store a bit in a nonvolatile mode, and/or it can store a bit in a fast, volatile mode - like the normal main memory
on your computer."
In this case, without losing of generality, and seeking simplicity of construction features, we will adopt low capacity features for cache and for main memory
. Thus, as data inputs for the design solution we admit that we have a 128KB cache (32K x 32b), (where we have used the B notation for a byte and b for bit) and a main memory
of 16 MB implemented with DRAM chips of 1KB.
My main memory
was at the final whistle, when a very large Villa fan - best described as a man mountain, and worst as an out-and-out hooligan - broke down and cried on my shoulder in the joy at Villa winning.
Configuration of the central server was as follows: HP Integrity rx6600, 4 processors / 8 cores / 16 threads, Dual-Core Intel Itanium 2 9050, 1.6 GHz, 32 KB(I) + 32 KB(D) L1 cache, 2 MB(I) + 512 KB(D) L2 cache, 24 MB L3 cache and 48 GB main memory
. The server was running the HP-UX 11iV3 operating system, Oracle Database 10g, and mySAP ERP 2005.
When the EU imposed the duty in 2003, it didn't specify that memory boards of dynamic random access memory chips, known as DRAM - the main memory
used in personal computers - were subject to the measure.
The desktop also features 256MB of main memory
and an 80GB hard drive, and runs Windows XP Home Edition ServicePack2.
The new benchmark results were achieved in an environment running SAP R/3 Enterprise Release 4.70 solution on a combined solution including NEC's Express5800/1320Xe, 32-way SMP, Intel Itanium 2, 1.6 GHz, 32 KB L1 cache, 256 KB L3 cache, 9 MB L3 cache, 128 GB main memory
, and iStorageS2000 SAN disk array system, Windows Server 2003 Datacenter Edition for Itanium-based systems and SQL Server 2000 (64-bit).
