Erlang Getting Too-Big-To-Fail Process Flag 35

From Joe Armstrong comes news that Erlang will soon feature a new process flag for those processes that just really need memory, or else: "Too big to fail processes behave like regular processes until they get too big and memory congestion occurs. If a memory allocation error is triggered when a too_big_to_fail process needs more memory, then a random smaller process is killed, and the system reattempts memory allocation for the too_big_to_fail process. An interesting situation can occur if the too big to fail process has killed all other processes and still cannot get enough memory. In this case the node running the process tries to memory steal from other nodes." Read below for your FREE logged-in-reader's-eye view of the special rot-39 version!

    Slashdot keeps making me log in to see ROT13. This April Fool's thing has gone too far. I want my normal ROT13 fare!
  • It doesn't work on this story...
  • Hey, they rolled out the special ROT-26 and bonus ROT-39 editions for the last minute before midnight Zulu-time April Fool's Day Edition!

    I assume developers will have to pay extra for use of this feature, ensuring ll the large companies get to slap it on all their processes and no one else does.

    I mean, ensuring the feature is used responsibly and not abused.

      So, this gets to be used by all those bank and loan institutions who use trade bots to manipulate the global stock market?

      Question: what happens if 2 such processes re running concurrently on the same node, and actively try to outperform the other by proactivally allocating all available free memory?

    • and I don't have to have error checking on my compilers any more. time to get back into programming!

    If this had been the only joke today, I think it would have worked.

    • The point of Slashdot on April fool's day is to collect the jokes from around the web. Not much original content here ever.

    None of the discussions today broke 3 digits on comments. Try something like this again, I am not coming back. Stupid rot13 trick. Whoever came up with the idea of running it this long should be fired summarily.
  • Angry developers, seeing this as little more than a back-door raid on their precious computing resources, are banding together in newly-formed TCP Parties, determined to resist meddling compiler makers and nebulous language specification agencies answerable to no one....

    Improper utilization of limited resources is a symptom of incorrect code.

    Vigil already has a much more elegant solution to the general problem of incorrect code:

    Rather than punish other programs, it simply deletes the offending code.

    All Vigil programs are guaranteed to run without error, eventually.

  • This sounds a lot like the Linux OOM killer. You can set the oomadj value to protect certain processes against the OOM killer, making it almost the same as these too-big-to-fail processes. I guess the only difference is stealing memory from other nodes.
