[sage-support] p-adic matrix norm.

2017-10-28 Thread sbrandhorst
Hi everyone, is there a norm method/function for p-adic matrices? For example the maximum norm would be quite useful for me. (it is of course easy to implement them yourself but ...) Best regards Simon -- You received this message because you are subscribed to the Google Groups "sage-support"

[sage-support] gap: cannot extend the workspace any more! with tons of free memory.

2018-05-29 Thread sbrandhorst
Dear all, I am running some calculations with libgap. At some point I get {{{ gap: cannot extend the workspace any more! }}} and sage quits disgracefully. Yet my memory manager claims that I still have 10 GB of free RAM. Is there a way to tell libGAP to extend the workspace? / raise the memo

Dear Volker, thank you for your answer. Could you please explain what you mean? If it helps, I seem to have "swap"?: This is how my memory looks like before gap crashes: Every 5.0s: free -m Wed May 30 22:03:55 2018 totalused

I upgraded the swap to 40 GB. The computation gets through now. Thank you. On Thursday, May 31, 2018 at 7:27:13 AM UTC+2, jori.ma...@uta.fi wrote: > > On Wed, 30 May 2018, sbran...@web.de wrote: > > > This is how my memory looks like before gap crashes: > > > > Every 5.0s: free -m

While adding swap helps a little, you have to add unreasonably much swap for things to work. The real reason is an internal memory limit in gap and libgap. You can set it with set_gap_memory_pool_size() from interfaces/gap.py and that helps. This solution is thanks to Dima in https://groups.
