The latter doesn't work in protected mode.

Some of them allow only 1 CUDA context at a time.
You need to create a CUDA context to get available VRAM.
So the client would run a CUDA job, then immediately kill it.
Solution:
- If a GPU app is running,
let it keep running regardless of available VRAM
(if it's still running, it has enough VRAM).
- But don't start new apps if there's not enough available VRAM,
or it the amount is unknown
(if the client can't create a CUDA context,
the app won't be able to either)
- client: if <coproc_debug> is set, print available GPU RAM periodically

- whether host is "reliable" for an app version
- whether host is eligible for single replication for an app version
- whether to use host scaling
In each case, the answer is yes if the number of
consecutive valid results is above a threshold.
This replaces existing "error rate" and "scale probation" mechanisms.
TODO: the # of consecutive valid results should also determine
a limit on jobs in progress for an app version.
Namely, if N is the threshold for host scaling, the limit should be
ndevices*(max(1, consecutive_valid - N))
The client currently doesn't supply enough
app version info to do this.
It could be approximated; that would give some protection
against cherry-picking.
- credit: more conservative formulas for combining claimed credit
among replicas.
If there are normal replicas, we use a "low average"
that weights each sample by the sum of the other samples.
Otherwise we use the min (not the average) of the approximate samples.
NOTE: a DB update is required

They're waiting for GPU RAM, which may now be available.

old: assign GPUs, then check available RAM
Problem: may cause starvation on multi-GPU systems.
new: use available RAM info in the assignment process.
Prevents starvation, also reduces the number of driver calls.
