A Cluster by Any Other Name Is Not a Grid

Filed under
Linux

Have you noticed how lately, when the conversation turns to distributed computing, grid and cluster are used as synonyms? These two words do have different meanings, Donald Becker reminds us.

So-called grid computing solutions for small to midsize businesses are more likely to be utility computing or clustering solutions, Becker says. A grid implementation is much more difficult. The only place for "true grid," he says, is with global enterprises that have a single point of administration for the CIO.

Becker knows whereof he speaks. While working at NASA's Goddard Space Flight Center during the late 1980s, Becker created the first Beowulf cluster, using software to connect many inexpensive PCs to solve complex math problems typically reserved for classic supercomputers.

Beowulf is a trademark controlled by Linux International.

Becker literally wrote-or rather co-wrote-the book on Beowulf Clustering: How to Build a Beowulf: A Guide to the Implementation and Application of PC Clusters.

Security Leftovers

  • Security updates for Wednesday
  • Microsoft says its best not to fiddle with its Windows 10 group policies (that don't work)

    On Monday, we revealed that a security researcher had used a packet sniffer to show that many settings designed to prevent access to the internet were being ignored with connections to a range of third party servers including advertising hubs.

  • What's got a vast attack surface and runs on Linux? Windows Defender, of course
    Google Project Zero's Windows bug-hunter and fuzz-boffin Tavis Ormandy has given the world an insight into how he works so fast: he works on Linux, and with the release of a personal project on GitHub, others can too. Ormandy's project is to port Windows DLLs to Linux for his vuln tests (“So that's how he works so fast!” Penguinistas around the world are saying). Typically self-effacing, Ormandy made this simple announcement on Twitter (to a reception mixing admiration, humour, and horror):
  • Hacked in Translation – from Subtitles to Complete Takeover
    Check Point researchers revealed a new attack vector which threatens millions of users worldwide – attack by subtitles. By crafting malicious subtitle files, which are then downloaded by a victim’s media player, attackers can take complete control over any type of device via vulnerabilities found in many popular streaming platforms, including VLC, Kodi (XBMC), Popcorn-Time and strem.io. We estimate there are approximately 200 million video players and streamers that currently run the vulnerable software, making this one of the most widespread, easily accessed and zero-resistance vulnerability reported in recent years.
  • A Samba remote code execution vulnerability
    Distributors are already shipping the fix; there's also a workaround in the advisory for those who cannot update immediately.
