A way a launch violates the kernel’s or the device’s budget.

Every variant names both sides of the comparison: a violation you cannot act on is a log line, not a gate.

Variants

BlockExceedsKernelMax

Block size exceeds what the compiled kernel supports (usually register pressure).

Fields

requested: u32

Threads per block the launch site asked for.

kernel_max: u32

What the compiled kernel supports.

BlockExceedsDeviceMax

Block size exceeds the device maximum.

Fields

requested: u32

Threads per block the launch site asked for.

device_max: u32

What the device supports.

SharedMemoryExceeded

Static + dynamic shared memory exceeds the per-block limit.

Fields

static_bytes: u32

Statically declared bytes.

dynamic_bytes: u32

Dynamically requested bytes.

total: u32

Their sum.

device_max: u32

Device per-block limit.

RegisterBudgetExceeded

Registers for the whole block exceed the per-block register file.

Fields

num_regs: u32

Registers per thread.

block_size: u32

Threads per block.

total: u32

Their product.

device_max: u32

Device per-block limit.

ZeroBlockSize

A zero-sized launch. Always a bug at the call site, never a legal request.

impl Eq for LaunchBudgetViolation

impl Error for LaunchBudgetViolation

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
