sage: V = libgap.GF(13)^500
sage: S = V.Subspaces(50)
sage: S.List()
gap: cannot extend the workspace any more!
As expected the computation runs out of memory. However, there is still a
lot of unused memory.
Before:
total used free shared
buff/cache available
Mem: 15G 1.8G 11G 290M 2.3G
13G
Swap: 39G 0B 39G
Right before termination
Mem: 15G 5.7G 7.6G 287M 2.3G
9.2G
Swap: 39G 0B 39G
After
total used free shared
buff/cache available
Mem: 15G 1.6G 11G 287M 2.3G
13G
Swap: 39G 0B 39G
In
https://groups.google.com/forum/#!topic/sage-support/m6R8_NKepyQ
it is suggested to increase the swap space.
However with 40 GB of swap I can only use about 4GB.
On a different machine with 64 GB of swap I can use about 8 GB.
However assigning more swap is impossible as I start to run out of hard
disk space.
Can you reproduce this behavior? Suggestions?
