MemoryError cph.initialize_allocator(cph.PoolAllocation, 1000000000) about cupoch HOT 5 CLOSED

Hi,
Does RMM work when used by itself?
https://docs.rapids.ai/api/rmm/stable/basics.html

import rmm

pool = rmm.mr.PoolMemoryResource(
    rmm.mr.ManagedMemoryResource(),
    initial_pool_size=2**30,
    maximum_pool_size=2**32
)
rmm.mr.set_current_device_resource(pool)

from cupoch.

RMM itself does work when using rapids-ai RMM module. To my surprise cupoch referenced rmm module did not compile as it complained about outdated make. Somehow this doesnt feel right.

from cupoch.

I have increased the version of RMM, so please try it with the latest master. (I don't use c++17, so it is not the latest RMM)

from cupoch.

i did check out and built it. still the same issue. btw, the upper rmm test hit a rmm module cupoch obviously did not compile against.

i remove my manually installed rmm (pip uninstall rmm)
