Member Function Documentation

static void SoCpuDevice::exitClass (  )  [static]

This function frees the allocated memory.

Reimplemented from SoDevice.

static SoCpuDevice* SoCpuDevice::findFirstAvailableDevice (  )  [static]

Returns the first available device found in the system.

SoCpuDevice::ProcessorArchitecture SoCpuDevice::getArchitecture (  )  const [inline]

Returns the architecture of the processor.

virtual unsigned long long SoCpuDevice::getAvailableMemory (  )  const [virtual]

Returns the current available memory of this device in bytes.

Implements SoDevice.

unsigned int SoCpuDevice::getCacheSize ( int  cacheLevel  )  const

Returns the size of the cache on this device in bytes.

Note: On Microsoft Windows platforms this function only returns a valid number on Windows XP SP3 and newer.

Parameters:
cacheLevel The cache level can be 1, 2, or 3.
static SoCpuDevice* SoCpuDevice::getDevice ( int  index = 0  )  [static]

Returns the device name.

Returns:
The device name.

Implements SoDevice.

static unsigned int SoCpuDevice::getDevicesCount (  )  [static]

Returns the total number of cores available in the sytem.

Reimplemented from SoDevice.

virtual SbString SoCpuDevice::getDriverVersion (  )  const [inline, virtual]

Returns the driver version of this device.


Always returns 0.0 on CPU device.

Implements SoDevice.

virtual unsigned int SoCpuDevice::getLogicalUnits (  )  const [virtual]

Returns the number of cores available on this device.

Note: On Microsoft Windows platforms this function only returns a valid number on Windows XP SP3 and newer.

Implements SoDevice.

int SoCpuDevice::getSSELevel (  )  const [inline]

Returns the SSE instruction level available on this device.

unsigned long long SoCpuDevice::getTotalMemory (  )  const [inline, virtual]

Returns the total memory of this device in bytes.

Implements SoDevice.

bool SoCpuDevice::hasMMX (  )  const [inline]
