Running out of memory

[oleksi...@gmail.com]

Hello, 

I supposed that the problem of memory limit was solved in nsp (in contrary to scicoslab), but I got the error 'running out of memory' when processing matrices multiplication. 

The monitoring of memory utilization in Linux (Lubuntu 19.10) through the command htop, showed that swap is not used during execution of the script and when the physical memory reached the limit (physical memory 8G /swap 8G). 

Is it an issue related to Linux management of memory or nsp?
