Hi, After perusing the texmfcnf.lua file, I created a file with the same name in my texmf-local folder, changing the settings for the node memory and step size, but it did not affect the compilation of the original MWE (without the enableexperiments switches), which still fails. What am I missing? Below the contents of the file: return { content = { directives = { ["luametatex.nodesize"] = { size = 60000000, step = 600000 }, } } } Marcus Vinicius On Fri, Sep 10, 2021 at 5:55 AM Marcus Vinicius Mesquita < marcusvinicius.mesquita@gmail.com> wrote:

Hi, Hans

The enableexperiments switches you pointed to solved the problem for the mwe I sent, but I'll take a look at the texmfcnf.lua configuration file to learn more.

Thank you for your suggestions.

Dear list,

In the MWE below, ConTeXt lmtx throws an error with the message in the title:

\starttext \startluacode

local upperlimit = 90000

context.starttabulate({ "|l|l|l|" }) for i=1,upperlimit do context.NC() context("word 1") context.NC() context("word 2") context.NC() context("word 3") context.NC() context.AR() end context.stoptabulate()

\stopluacode \stoptext

But it compiles with no problems with MKIV.

context version: 2021.09.06 11:47

How to avoid this with lmtx? In luatex there is also a max on configured memory usage but because in luametatex we have larger nodes you hit limits earlier. Also, the memory allocation in luametatex is somewhat different (larger nodes are compensated by savings elsewhere so in the end mem usage for this run is similar).

luatex luametatex

pages 2196 2196 pps/s 8 11 time 278 195 mem 1.1G 1.1G

now, luametatex reports

tex memory > bumping category 'node' succeeded, details: all=400500000 | ini=0 | max=50000000 | mem=44500000 | min=1000000 | ptr=-843956 | set=50000000 | stp=500000 | top=43999999

you can bump the the max in the configuration file and also the step. As you can see, luametatex runs quite a bit faster on this test but that is due to other differences between the two engines.

The reason why it does run on my machine is that i have this:

\enableexperiments [tabulatesparseskips] \enableexperiments [tabulateusesize]

this makes tabulate a bit more efficient in terms of node usage so i stay some 20% below the configured max .. you can try to run with this option. Of course adding more text will also demand more mem but then you can always bump the max (in a configuration file in texmf-local or so; maybe some day i will add a --huge flag to the runner).

Yes, in texmf-local/web2c Only mtxrun --generate But even after now also running context --make, when compiling the mwe, lmtx throws: tex error > tex error on line 540005 in file ./mwe.tex: TeX capacity exceeded, sorry [node memory size=50000000] On Fri, Sep 10, 2021 at 8:49 AM Hans Hagen wrote:
