  • Why do we need different CPU architecture for server & mini/mainframe & mixed-core?

    - by claws
    Hello, I was just wondering what other CPU architectures are available other than INTEL & AMD. So, found List of CPU architectures on Wikipedia. It categorizes notable CPU architectures into following categories. Embedded CPU architectures Microcomputer CPU architectures Workstation/Server CPU architectures Mini/Mainframe CPU architectures Mixed core CPU architectures I was analyzing the purposes and have few doubts. I taking Microcomputer CPU (PC) architecture as reference and comparing others. Embedded CPU architecture: They are a completely new world. Embedded systems are small & do very specific task mostly real time & low power consuming so we do not need so many & such wide registers available in a microcomputer CPU (typical PC). In other words we do need a new small & tiny architecture. Hence new architecture & new instruction RISC. The above point also clarifies why do we need a separate operating system (RTOS). Workstation/Server CPU architectures I don't know what is a workstation. Someone clarify regarding the workstation. As of the server. It is dedicated to run a specific software (server software like httpd, mysql etc.). Even if other processes run we need to give server process priority therefore there is a need for new scheduling scheme and thus we need operating system different than general purpose one. If you have any more points for the need of server OS please mention. But I don't get why do we need a new CPU Architecture. Why cant Microcomputer CPU architecture do the job. Can someone please clarify? Mini/Mainframe CPU architectures Again I don't know what are these & what miniframes or mainframes used for? I just know they are very big and occupy complete floor. But I never read about some real world problems they are trying to solve. If any one working on one of these. Share your knowledge. Can some one clarify its purpose & why is it that microcomputer CPU archicture not suitable for it? Is there a new kind of operating system for this too? Why? Mixed core CPU architectures Never heard of these. If possible please keep your answer in this format: XYZ CPU architectures Purpose of XYZ Need for a new architecture. why can't current microcomputer CPU architecture work? They go upto 3GHZ & have upto 8 cores. Need for a new Operating System Why do we need a new kind of operating system for this kind of archictures?

  • How to install missing Sound Drivers in Ubuntu?

    - by Sakamoto Kazuma
    I seem to be missing drivers for my Gateway laptop MA7. I have looked in System-Admin-Hardware Drivers, but it does not show up in there.There are also no devices listed in Sound-Hardware. I'm guessing at this point that I don't have the driver installed. However, I get the following output: admin@machine001:~$ cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xd8240000 irq 22 admin@machine001:~$ And my lspci shows: 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 2 (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 02) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev e2) 00:1f.0 ISA bridge: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 02) 00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) SATA AHCI Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 02) 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8038 PCI-E Fast Ethernet Controller (rev 14) 03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) 04:09.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller 04:09.1 FireWire (IEEE 1394): Texas Instruments PCIxx12 OHCI Compliant IEEE 1394 Host Controller 04:09.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD) I have also checked alsamixer, and nothing is muted.

  • Can not get sound over hdmi in kubuntu 9.10

    - by user32509
    I have used a hdmi cable to connect my lcd (which is connected with my speakers) with my nvida 275 gtx grafic card. I can not get the sound output to work. The hardware itself is working probably - I tested it under windows. Currently I am running Kubuntu 9.10 64 with Nvidia 190.53. The sound output worked fine before I installed the hdmi connection.

  • Wireless not working - HP Probook 4540s

    - by Oguzhan
    I just installed Ubuntu 12.04 on 3 HP Probook 4540s's, and none of them seems to be able to connect to wireless networks. I have 1 Probook 4540s with Windows 7 installed and I can access wlan from it. I tried installing the necessary drivers from HP's website, but it still doesn't seem to be working. I've seen other people with different Probooks having similar problems, but their computers seem to be able to detect and even attempt to connect wlans, while mine doesn't even acknowledge that it has wireless. Any help would be appreciated. lspci: 00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Ivy Bridge PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.2 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 3 (rev c4) 00:1c.3 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 4 (rev c4) 00:1c.5 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 6 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Thames [Radeon 7500M/7600M Series] 03:00.0 System peripheral: JMicron Technology Corp.

  • Wifi range issues and intermittent dropouts, Thinkpad Edge

    - by jimbo
    If I am more than a couple of metres from my access point (and I'm seeing this across various APs) with my newish Thinkpad Edge 15, running 10.10, the wifi performance becomes ... flaky. When this is happening, I see the following in dmesg, although I'm not sure if it's related: [ 2497.011099] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2502.012711] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2507.009254] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2512.008367] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2517.007467] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2522.006558] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2527.008157] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2532.007251] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2537.003838] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2542.005427] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2547.004496] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded [ 2552.003611] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded lspci -vvv has the following to say about my wireless adapter: 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 49 Region 0: Memory at f0500000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: iwlagn Kernel modules: iwlagn If I get within a couple of metres of the access point, I still see that output in dmesg, but the connection stabilises. My question is threefold: how do I get better wifi range, what can/should I do about those messages in dmesg, and most crucially, are the two related? As ever let me know if there's other information that would help! Edit: I am using this machine in exactly the same locations I used my previous Thinkpad (T61) running various older versions of Ubuntu, so I definitely feel there is something wrong, rather me having unreasonable expectations of range!

  • No WIFI or LAN on Ubuntu 12.04 or 12.10 Live CD/USB using Toshiba qosmio x870

    - by Mighty
    I recently had issues with secure boot and couldn't boot the Live CD/USB but after disabling secure boot, I was able to 'TRY UBUNTU'. My currently problem is that I can't access WIFI or LAN from either Ubuntu 12.04 or 12.10 Live CD/USB which I do from Windows 8. Also, the wireless button is able to turn on and off the wireless LED but doesn't find available WIFI. Please, what should I do to get both WIFI and LAN working on Ubuntu using Toshiba qosmio x870?

  • How does loop address alignment affect the speed on Intel x86_64?

    - by Alexander Gololobov
    I'm seeing 15% performance degradation of the same C++ code compiled to exactly same machine instructions but located on differently aligned addresses. When my tiny main loop starts at 0x415220 it's faster then when it is at 0x415250. I'm running this on Intel Core2 Duo. I use gcc 4.4.5 on x86_64 Ubuntu. Can anybody explain the cause of slowdown and how I can force gcc to optimally align the loop?

  • SPARC T4-4 Beats 8-CPU IBM POWER7 on TPC-H @3000GB Benchmark

    - by Brian
    Oracle's SPARC T4-4 server delivered a world record TPC-H @3000GB benchmark result for systems with four processors. This result beats eight processor results from IBM (POWER7) and HP (x86). The SPARC T4-4 server also delivered better performance per core than these eight processor systems from IBM and HP. Comparisons below are based upon system to system comparisons, highlighting Oracle's complete software and hardware solution. This database world record result used Oracle's Sun Storage 2540-M2 arrays (rotating disk) connected to a SPARC T4-4 server running Oracle Solaris 11 and Oracle Database 11g Release 2 demonstrating the power of Oracle's integrated hardware and software solution. The SPARC T4-4 server based configuration achieved a TPC-H scale factor 3000 world record for four processor systems of 205,792 QphH@3000GB with price/performance of $4.10/QphH@3000GB. The SPARC T4-4 server with four SPARC T4 processors (total of 32 cores) is 7% faster than the IBM Power 780 server with eight POWER7 processors (total of 32 cores) on the TPC-H @3000GB benchmark. The SPARC T4-4 server is 36% better in price performance compared to the IBM Power 780 server on the TPC-H @3000GB Benchmark. The SPARC T4-4 server is 29% faster than the IBM Power 780 for data loading. The SPARC T4-4 server is up to 3.4 times faster than the IBM Power 780 server for the Refresh Function. The SPARC T4-4 server with four SPARC T4 processors is 27% faster than the HP ProLiant DL980 G7 server with eight x86 processors on the TPC-H @3000GB benchmark. The SPARC T4-4 server is 52% faster than the HP ProLiant DL980 G7 server for data loading. The SPARC T4-4 server is up to 3.2 times faster than the HP ProLiant DL980 G7 for the Refresh Function. The SPARC T4-4 server achieved a peak IO rate from the Oracle database of 17 GB/sec. This rate was independent of the storage used, as demonstrated by the TPC-H @3000TB benchmark which used twelve Sun Storage 2540-M2 arrays (rotating disk) and the TPC-H @1000TB benchmark which used four Sun Storage F5100 Flash Array devices (flash storage). [*] The SPARC T4-4 server showed linear scaling from TPC-H @1000GB to TPC-H @3000GB. This demonstrates that the SPARC T4-4 server can handle the increasingly larger databases required of DSS systems. [*] The SPARC T4-4 server benchmark results demonstrate a complete solution of building Decision Support Systems including data loading, business questions and refreshing data. Each phase usually has a time constraint and the SPARC T4-4 server shows superior performance during each phase. [*] The TPC believes that comparisons of results published with different scale factors are misleading and discourages such comparisons.

Performance projections and comparisons between different TPC-H Database sizes (100GB, 300GB, 1000GB, 3000GB, 10000GB, 30000GB and 100000GB) are not allowed by the TPC. TPC-H is a data warehousing-oriented, non-industry-specific benchmark that consists of a large number of complex queries typical of decision support applications. It also includes some insert and delete activity that is intended to simulate loading and purging data from a warehouse. TPC-H measures the combined performance of a particular database manager on a specific computer system. The main performance metric reported by TPC-H is called the TPC-H Composite Query-per-Hour Performance Metric (QphH@SF, where SF is the number of GB of raw data, referred to as the scale factor). QphH@SF is intended to summarize the ability of the system to process queries in both single and multiple user modes. The benchmark requires reporting of price/performance, which is the ratio of the total HW/SW cost plus 3 years maintenance to the QphH. A secondary metric is the storage efficiency, which is the ratio of total configured disk space in GB to the scale factor. Key Points and Best Practices Twelve Sun Storage 2540-M2 arrays were used for the benchmark. Each Sun Storage 2540-M2 array contains 12 15K RPM drives and is connected to a single dual port 8Gb FC HBA using 2 ports. Each Sun Storage 2540-M2 array showed 1.5 GB/sec for sequential read operations and showed linear scaling, achieving 18 GB/sec with twelve Sun Storage 2540-M2 arrays. These were stand alone IO tests. The peak IO rate measured from the Oracle database was 17 GB/sec. Oracle Solaris 11 11/11 required very little system tuning. Some vendors try to make the point that storage ratios are of customer concern. However, storage ratio size has more to do with disk layout and the increasing capacities of disks – so this is not an important metric in which to compare systems. The SPARC T4-4 server and Oracle Solaris efficiently managed the system load of over one thousand Oracle Database parallel processes. Six Sun Storage 2540-M2 arrays were mirrored to another six Sun Storage 2540-M2 arrays on which all of the Oracle database files were placed. IO performance was high and balanced across all the arrays. The TPC-H Refresh Function (RF) simulates periodical refresh portion of Data Warehouse by adding new sales and deleting old sales data. Parallel DML (parallel insert and delete in this case) and database log performance are a key for this function and the SPARC T4-4 server outperformed both the IBM POWER7 server and HP ProLiant DL980 G7 server.

  • Attempting to load a 64-bit application, how this CPU is not compatible with 64-bit mode

    - by Brandon Michael Hunter
    I have a Dell Studio 540, 64 bit OS Windows Home Premium. My CPU is supports Intel's virtualization technology, but I don't know how to enabled it on my machine. I saw that you can do it via the bios, but I didn't see this option when going through my BIOS. Is there another way to enabled this feature? Please let me know. I'm trying to installed Windows Server 2008 via Vircutal PC 2007. Thank You,

  • Is there a way to reliably detect the total number of CPU cores?

    - by John Sheares
    I need a reliable way to detect how many CPU cores are on a computer. I am creating a numerically intense simulation C# application and want to create the maximum number of running threads as cores. I have tried many of the methods suggested around the internet like Environment.ProcessorCount, using WMI, this code: http://blogs.adamsoftware.net/Engine/DeterminingthenumberofphysicalCPUsonWindows.aspx. None of them seem to think a AMD X2 has two cores. Any ideas?

  • how to open many tabs in chromium but unload/disable inactive/notCurrent ones, releasing memory and cpu?

    - by Aquarius Power
    So I have 50 tabs opened on chromium, but that is using too much memory and some of the CPU. How can I have all those concurrent researches I am doing opened but not clog my machine? I think there should have a way that only the active tab is loaded in memory and running, and all the others should stay closed/unloaded from memory, until I want to look at them... Any extension can do something like that?

  • Drawing particles with CPU instead of GPU (XNA)

    - by Helix
    I'm trying out modifications to the following particle system. http://create.msdn.com/en-US/education/catalog/sample/particle_3d I have a function such that when I press Space, all the particles have their positions and velocities set to 0. for (int i = 0; i < particles.GetLength(0); i++) { particles[i].Position = Vector3.Zero; particles[i].Velocity = Vector3.Zero; } However, when I press space, the particles are still moving. If I go to FireParticleSystem.cs I can turn settings.Gravity to 0 and the particles stop moving, but the particles are still not being shifted to (0,0,0). As I understand it, the problem lies in the fact that the GPU is processing all the particle positions, and it's calculating where the particles should be based on their initial position, their initial velocity and multiplying by their age. Therefore, all I've been able to do is change the initial position and velocity of particles, but I'm unable to do it on the fly since the GPU is handling everything. I want the CPU to calculate the positions of the particles individually. This is because I will be later implementing some sort of wind to push the particles around. How do I stop the GPU from taking over? I think it's something to do with VertexBuffers and the draw function, but I don't know how to modify it to make it work.

  • check what process was causing the problem of high cpu load

    - by linuxk
    I'm running nginx wordpress server in KVM using 12.04 server x86. It was running very well about 4 month until 2 hours ago. I found that my website is down and no ping response. Virt-manager logged high cpu load(plz see the picture below) before unexpected shut down. I want to know what process caused unexpected shutdown. The following log files make me think my server is attacked. Any suggestions and help would be appreciated. kern.log and syslog showed me same output.

  • Xna, after mouse click cpu usage goes 100%

    Hi i have following code and it is enough just if i click on blue window then cpu goes to 100% for like at least one minute even with my i7 4 cores. I just check even with empty project and is the same !!! public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; private Texture2D cursorTex; private Vector2 cursorPos; GraphicsDevice device; float xPosition; float yPosition; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; } protected override void Initialize() { Viewport vp = GraphicsDevice.Viewport; xPosition = vp.X + (vp.Width / 2); yPosition = vp.Y + (vp.Height / 2); device = graphics.GraphicsDevice; base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); cursorTex = Content.Load<Texture2D>("strzalka"); } protected override void UnloadContent() { // TODO: Unload any non ContentManager content here } protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(cursorTex, cursorPos, Color.White); spriteBatch.End(); base.Draw(gameTime); } }
