It describes computers with multiple processing elements that perform the same operation on multiple data simultaneously. Thus, such machines exploit data level parallelism. History The first use of SIMD instructions was in vector supercomputers of the early 1970s such as the CDC Star-100 and the Texas Instruments ASC, which could operate on a vector of data with a single instruction. Vector processing was especially popularized by Cray in the 1970s and 1980s. Vector-processing architectures are now considered separate from SIMD machines, based on the fact that vector machines processed the vectors one word at a time through pipelined processors (though still based on a single instruction), whereas modern SIMD machines process all elements of the vector simultaneously.[1] The first era of modern SIMD machines was characterized by massively parallel processing-style supercomputers such as the Thinking Machines CM-1 and CM-2. These machines had many limited-functionality processors that would work in parallel. -
Issues with Using IE9 Browser
NOTICE: Browser Compatibility Issues with Internet Explorer 9 VIPR uses eAuthentication for authentication and the eAuth system is most compatible with Internet Explorer 8. Therefore, IE8 is the preferred browser for use with VIPR. Older versions of Internet Explorer (IE6, IE7) as well as the current version of Mozilla Firefox are working options also. If a customer is using IE9 and having issues, there are several options available to the user in this case: Option 1: Change IE9 to browse in IE8 mode • Open IE9 and hit the F12 key (or Tools > Developer Tools Menu). Click Browser Mode and select IE8. Try again. Option 2: Download Mozilla Firefox, make it your default browser, and try again • Mozilla Firefox can be downloaded from http://www.mozilla.org/en-US/firefox/new/ • To make Firefox the default browser: 1. At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP) and then click Options. 2. Select the Advanced panel, then click the General tab, and then click Check Now. 3. Select Yes to set Firefox as your default browser. Option 3: Rollback from IE9 to IE8 1. Open the Control Panel. Click on Programs and Features. This may be called Add/Remove programs if you are using an older version of Windows. 2. Click on View Installed Updates in the left pane. 3. Right click on Windows Internet Explorer 9 and select Uninstall. 4. Restart your computer when prompted and it should now be running IE8. If you continue to have issues with logging into VIPR, please contact the IIA Helpdesk at 866-224-7677, or by e-mail at [email protected]. -
Böngésző Programok 23. Tétel
23.tétel 1.0 Böngész ő programok használata, összehasonlítása. Az információ keresés technikái. Bogdán;Sleisz Böngész ő programok (Használata, összehasonlítása. Az információ keresés technikái) 23. tétel Az Internet kialakulása 20. század második felére helyezhet ő. Az ARPA rendszerb ől fejl ődött tovább az USA-ban, azóta folyamatosan fejlesztgetik a különböz ő protokollokat, illetve technológiákat, az adatforgalom sebességének növelése érdekében. Komoly tévhitet képez a világban, hogy az Internet az a böngész őben megjeleníthet ő weboldalak összessége. Nagy tévedés, ugyanis ez csak a HTTP protokoll által szolgáltatott tartalom, amely a teljes internetes adatforgalomnak kevesebb, mint az 1/10-ét képezi. Az internetet úgy kell elképzelni, mint egy hardvereszközt, ami az egész világot lefedi, a rajta elérhet ő szolgáltatásokat pedig nevezzük "szoftvereknek". Kétségkívül az egyik legelterjedtebb szolgáltatás ("szoftver") a 80-as port -on kommunikáló HTTP protokoll, amihez tartozik egy kommunikációs nyelv is. A HTTP protokoll célja hagyományos esetben- a távoli "szerveren/kiszolgálón" elhelyezked ő weboldal letöltése a helyi számítógépre. 1. A böngész ő a HTTP kommunikációs nyelven megfogalmazott kérést küld a szerver felé, hogy szeretnénk megjeleníteni a kért weboldalt 2. A szerver válaszol. Többféle üzenetet küldhet vissza a böngész őnek, és minden üzenethez tartozik egy azonosító szám is, úgynevezett Status Code. A legismertebb visszatérési érték talán a Not Found (a keresett weboldal nem található), melynek Status Code-ja a 404. Ilyet könnyedén el őidézhetünk, ha pl. nem létez ő oldalt próbálunk letölteni. A leggyakoribb azonban, ha a 200-as üzenetet kapjuk vissza, vagyis megjelenik az oldal. 3. Ezek után a böngész ő elkezdi letölteni a kért oldal forráskódját . A forráskód egy olyan leíró kód nagyrészt HTML nyelven, amely leírja, hogyan néz ki a weboldal. -
