FreeBSD/Alpha SMP fully multiuser stable and checked in

Posted by CmdrTaco on from the isnt-that-special dept.

David O'Brien writes " FreeBSD SMP on Alpha processors is now stable and has been checked into CVS repository on the development branch (5.0-CURRENT). John Baldwin, Andrew Gallatin, and Doug Rabson first booted single-user SMP on Friday, April 13th, and full multi-user support followed on Tuesday, April 17th. The code was stablized and then checked into the CVS repository on Friday, April 27th. Since being checking into the repository, it has been verified to work on quad-CPU DEC AlphaServer 4100s, dual-CPU Compaq DS-20s, dual-CPU API UP2000, and dual-CPU DEC AlphaServer 2100s. "

    I build and run FreeBSD-CURRENT for years on AMD boxes (at present K7-700 at work and K6-300 at home) and had no processor problems at all.

    My guess is that your motherboard is either bad quality, or perhaps needing a decent BIOS update. Another candidate could be your RAM. I once had problems with an old Asus SC-200 SCSI controller, that was not up to the task with faster systems anymore. Overclocking is a bad idea as well.

    "thou" ? Hahahhahaha you are the moron. The correct word is "thee" because you are using an objective pronoun, not a subjective pronoun. Thou art stupid. I art less stupid than thee.

    And, given how AMD K6es can't go thru a build world without a SIG 11

    Considering I develop and maintain the GCC/Binutils toolchain on AMD K6 machines, I can say absolutely this is false. You may easily have a HW problem. I would bring this up in one of the FreeBSD mailing lists to help determine what your problem is. I will note, I had to increase the voltage on one of my K6-2/450 machines by 0.1v, other wise it would SIG 11 as you mention. `make world' really stresses a machine and if your mobo just isn't keeping the volage up, you will have problems.

    Yet it is not so great that FreeBSD will replace it with BSDi's SMP code.

    No code is being replaced. They're not merging the BSD/OS 5.0 experimental kernel at all; SMPng is based off of some of the design concepts in it.

    If FreeBDS 5.0 really does get an "entirely overhauled SMP structure" in six months, then it will be just that: immature code that's only been around a few months.

    *BSD tests it first before releasing it. It makes more sense then to throw it to the public. When was the last time a *BSD had an ontime release?

    If FreeBSD's TCP/IP is so kewl, then why doesn't anyone submit SPECweb benchmarks using FreeBSD for the 1 CPU category? Linux wipes the floor with Solaris, AIX, Tru64, and Windows 2000.

    It's not Linux thats wiping the floor, its TUX; the tiny in-kernel httpd that is designed for TRIVIAL matters. Putting the daemon inkernel is a glaring risk. It doesn't match the completeness of other userland servers like Apache.
