1. Memory Hardware Support For Sparse Computations Address computations and indirect, hence double, memory accesses in sparse matrix application software render sparse computations to be inefficient in general. In this paper we propose memory architectures that support the storage of sparse vectors http://www.wi.leidenuniv.nl/TechRep/1994/tr94-44.html

Screens NV30 With 400MHz but Limited Memory Wednesday October 16, 2002 post a comment : 130 total Description According to the latest NV30 rumours, leaked information suggests that the NV30 range of cards will feature clock speeds centred around the 400 MHz mark. Although initially nVidia had suggested that they were aiming for lower clock speeds than that, it is slowly becoming evident that 400 MHz is what the graphics company will rely on. Other information about the upcoming chip remains as it was. It will carry 8 pipelines and will consist of 120 million transistors built on the 0.13 micron process. What does seem, initially, to be worrying for all nVidia fans is that the card will almost certainly rely on a 128 Mbit memory. Yup that is half compared to the 256 Mbits (DDR) which the 9700 and 9700 Pro's carry. It is of course unlikely that nVidia will not go out of their way to demonstrate how they have compensated for that and still managed to produce a top notch card. It seems that benchmarks will once again rule the net.

Pentium 4 Memory Comparison Pentium 4 Memory Comparison February 6, 2002 Introduction As we mentioned in our last article, the Pentium 4 2.2Ghz "Northwood" review , we were going to be doing a comparison of the types of RAM available for the Pentium 4, after much work it's finally here. We have setup several systems and ran our normal suite of benchmarks and compared the memory subsystems that are now offered for the Pentium 4 - RDRAM, DDR RAM, and SDRAM. In our two part article, we will be doing a comparison of the three memory systems and a system guide to help you select the best system components for the different types of memory. We've got a lot ahead so sit back and relax and enjoy the show... Continue to the next page...

4. Memory Hardware PC memory hardware over the years. The Evolution Of The Memory Chip. Upgradingmemory and reusing memory from older generation PC computer hardware. http://members.iweb.net.au/~pstorr/pcbook/book2/memchips.htm

Phil Storrs PC Hardware book PC Memory hardware over the years The Evolution Of The Memory Chip The first few generations of DOS computer used Dual In Line (DIL) memory chips and since 1981 (when the PC computer was designed) memory chip technology increased the capacity of RAM Chips in steps of four times capacity, regularly. The first IBM PC used 16K by 1 bit RAM chips. Soon 64K by 1 bit chips were available and in regular use. The 256K by 1 bit made 640K on the system board possible. The original PC had a nine bit memory word, where the extra bit was used for Parity. Parity is a means of checking for errors in data stored in a memory. The parity bit is set to either a Zero or a One depending on the number of ones in the word when the word is written into the memory. When that same location is read, the parity bit in the memory is checked against a parity bit generated from the data that is read from memory. If an error is detected the user is notified of the problem. Not all DOS computers are fitted with parity chips. Four generations of RAM devices DIL RAM (Historic interest only) The first few generations of DOS computers used Dual-in-line RAM chips. Over the years these devices increased from 16K bits in the first IBM PC, 64k bit chips used in the first clone PC's, to one Meg bit chips in the last PC computers to use this RAM technology.

Memory Hardware Problem? Follow Ups CBUG's Home Post Followup CBUG Bulletin Board ... FAQ Posted by Mel Morganstein on June 08, 2001 at 17:39:52: When my wife's computer boots, we get the following message: "HIMEM.SYS has detected unreliable memory at address 01C017EE, XMS Driver not installed" We are then informed that, as a result, Windows was not installed. However, when I hit Ctrl-Alt-Del to continue as recommended, most often the PC will ultimately boot into Windows 98 as it should. At one point, I also got a message that there was a bad or missing HIMEM.SYS. I tood a chance that it was not completely corrupted but that there was a bad spot developing on the HD. I copied the HIMEM.SYS file from the Windows would put it in a "workable" spot on the HD! I have not seen that bad/ missing file message again. However, we got the "....unreliable XMS memory...." message again. Is this the time to get replacement memory board and replace what's there? (Or maybe pull and reseat the boards on the chance there is a bad contact? I haven't opened the case yet to see what there is in the way of memory in her PC yet!

Fred Chong I'm a doctoral student working with Anant Agarwal in the Alewife group. I will be starting November 1, 1996, as an assistant professor of computer science at the University of California at Davis I was recently the Program Chair for the 5th Annual MIT Student Workshop on Scalable Computing , Wellesley, MA, August 1995. Dissertation Research: Parallel Systems Evaluation with Sparse, Irregular Applications Parallel systems are becoming a significant computing technology, not only for high performance computing, but also for commodity servers. These systems, however, are often built with communication mechanisms chosen from intuition or anecdotal experience. The goal of my research is to identify core mechanisms which both exploit architectural trends and support real applications. My thesis demonstrates that cache-coherent shared memory hardware is such a core mechanism, even for applications with little data re-use and data-driven synchronization. I make two major contributions. First, I perform an in-depth study of the interaction between communication mechanisms and sparse, irregular applications . Second, I present the

17. Overcoming The Memory Wall These techniques use existing memory hardware more effectively. Forexample, altering the execution order can exploit memory hardware http://www.llnl.gov/CASC/sc2001_fliers/MemWall/MemWall01.html

Overcoming the Memory Wall Overview CPU speeds double approximately every eighteen months, while main memory speeds double only about every ten years. These diverging rates imply an impending "Memory Wall," in which memory accesses dominate code performance. The Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory (LLNL) , in collaboration with the University of Utah Figure 1. The FPGA memory controllers and MAPS of the SRC-6 are an ideal test bed for SMP-based DAO. Standard memory access techniques do not use memory bandwidth effectively. Many researchers anticipate a Memory Wall in which memory accesses imply an absolute performance limit, and improvements in CPU speed provide no performance benefit. Dynamic access optimization (DAO) mechanisms can use the memory system more effectively by changing the order or apparent location of memory accesses from those generated by the issuing program to ones that use the memory system more effectively without changing the results, thus lowering the Memory Wall. This project is extending DAO mechanisms to consider additional memory access issues, such as cache coherency, that arise in symmetric multiprocessors (SMPs). The deliverables of this project include recommended improvements to the compilers, operating systems, and firmware of SMP-based systems. These modifications could be of significant benefit to scientific codes and reduce the run times of many LLNL codes by a factor of three or more without any source code modifications.

Virtual Memory Hardware Page last updated Characteristics of Virtual Memory Memory references within a process are logical addresses dynamically translated to physical addresses at runtime. A process is broken into pages or segments Not all the pages or segments need to be in memory at the same time More processes may be maintained in memory than normally permitted if entire address spaces of processes had to reside in memory Processes can be larger than actual physical memory Resident set - the pages or segments of a process that are in real memory. Real memory - the actual physical memory of the hardware Virtual memory - the perceived memory space for a process. Locality Locality is the reason VM works so well. The nature of program execution is that most often a memory reference is one that has recently been accessed or is one that is very close to a recently accessed location. sequential execution of code (nearby code) loops (nearby and already accessed code) repeated calls to subroutines sequential processing of data structures Figure 8.1 is a classic mapping of paging behavior, demonstrating the existence of locality.
