SBCL错误：在Linux机器上运行Maxima时“绑定堆栈耗尽”

我知道有很多地方可以问这个问题,但我想我会在这里试试.我已经看起来已经从Maxima的好人那里得到了尽可能多的帮助.

我用SBCL运行Maxima并且一直出错;

INFO: Binding stack guard page unprotectedBinding stack guard page temporarily Disabled: proceed with cautionMaxima encountered a lisp error: Binding stack exhausted.PROCEED WITH CAUTION.automatically continuing.To enable the lisp deBUGger set *deBUGger-hook* to nil.INFO: Binding stack guard page reprotected

我已经通过为动态空间大小和控制堆栈大小添加更大的值来修改对Maxima(其可执行文件)的调用,并且我已经查看了./…/sbcl-help以获取要添加到$的参数的任何想法maxima可执行文件中的MAXIMA_liSP_OPTIONS.

另外,我通常在运行它之前做这些(虽然我认为它们是不必要的,因为 *** 作系统很聪明,也许最后一个需要摆弄);

sudo fstrim -v /echo 3 | sudo tee /proc/sys/vm/drop_cachesecho 262144 | sudo tee /proc/sys/vm/max_map_count

在完成我的千里马工作的几次计算之后,我扔了几个

:lisp (sb-ext:gc :full t)

希望避免这个错误.我不太了解lisp,当然也不了解垃圾收集的所有内容.

虽然我在Maxima工作中使用了memoization,但我的计算有点密集和递归.我的电脑用inxi -b描述为,

System:    Host: XXX-MacBookPro Kernel: 4.10.0-33-generic x86_64 (64 bit) Desktop: Cinnamon 3.4.6           distro: linux Mint 18.2 SonyaMachine:   System: Apple (portable) product: MacBookPro11 3 v: 1.0           Mobo: Apple model: Mac-2BD1B313 v: MacBookPro11 3           Bios: Apple v: MBP112.88Z.0138.B25.1702171721 date: 02/17/2017cpu:       Quad core Intel Core i7-4980HQ (-HT-MCP-) speed/max: 1402/4000 MHzGraphics:  Card: NVIDIA GK107M [GeForce GT 750M Mac Edition]           display Server: X.Org 1.18.4 drivers: nvIDia (unloaded: fbdev,vesa,nouveau)           Resolution: 2880x1800@59.99hz           GLX Renderer: GeForce GT 750M/PCIE/SSE2 GLX Version: 4.5.0 NVIDIA 375.66Network:   Card-1: broadcom BCM4360 802.11ac Wireless Network Adapter driver: wl           Card-2: broadcom NetXtreme BCM57762 Gigabit Ethernet PCIE driver: tg3Drives:    HDD Total Size: 1000.6GB (17.5% used)Info:      Processes: 291 Uptime: 43 min Memory: 3366.6/15953.7MB ClIEnt: Shell (bash) inxi: 2.2.35 

我的Maxima和SBCL是由GIT构建的,并且是相当新的〜大约2周,从头部开始并且已经通过了他们所有的制造测试.另外我的交换看起来像;

XXX@XXX-MacBookPro ~/ResearchWC $cat /proc/swaps filename                Type        Size    Used    Priority/70GiB.swap                             file        73400316    0   -2/dev/sda7                               partition   25564776    0   -1

而且我经常基本上没有内存和大约20-30G进入交换.

通常它似乎最终会挂起(比如说100小时之后,因为我注意到htop停止显示某些活动并且风扇不会上下移动)我认为耗尽错误有时会隐藏在嵌入式递归调用中.我收到上面的错误消息,因为我避免在我想要的递归级别调用函数,而是在终端“手动”构建它们. E.G.,而不是仅仅调用像fib(10)这样的东西,而是连续地调用fib(1),fib(2),fib(3),其中每个先前的值都被记忆.

我有时间,但似乎不知道如何最大化我的交换 – 观看htop我从未见过它使用超过说~25％.

1.)有谁知道我还可以用SBCL做些什么来避免这些错误？

2.)在这些情况下,另一个lisp是否会更好,例如ecl,cml等？

提前感谢您的任何建议,如果需要,我可以提供更多详细信息.

UPDATE

在增加动态空间大小,堆栈大小和绑定堆栈大小之后,这次崩溃时我遇到了堆限制而不是绑定堆栈.附加是回溯的输出(不确定两个寄存器pc和fp是什么…… – 程序计数器和帧指针？).我用痕迹(残留物,泰勒)也跑了这个,但从来没有看到任何可疑的东西……

最佳答案绑定堆栈溢出的最常见原因是递归函数,它无限地调用自身(即递归中的错误).第二个最常见的原因是一个正确编程的递归函数,但调用自身太多次以使lisp实现处理它.

我忘记了SBCL的堆栈限制 – 它可能是8192,但这只是猜测.您可以通过实验确定它(如果不是通过阅读SBCL文档).

在任何一种情况下,您都可以尝试找出导致故障的功能

trace (mymaximafun1,mymaximafun2,...);

对于Maxima函数和/或

:lisp (trace mylispfun1 mylispfun2 ...)

对于lisp函数.

关于第二个问题,您可以尝试通过将递归函数重新设置为迭代来避免深度递归.

你提到你有长时间运行的计算.减少崩溃影响的策略是调用save函数来不时地保存程序状态,例如：

save ("mycheckpointfile.lisp",all);

请注意,保存需要很多选项,所以可以通过文档看一下？保存.

您可以通过某些配方自动生成文件名,例如file_name：printf(false,“mycheckpointfile~d.lisp”,1000 random(9000)),它会生成一个随机的4位数字并将其粘贴到文件名中.当然有很多这样的食谱.
