/* ERROR/WARNING messages:
|
|
|
|
E: The package gpu command is required for gpu styles
|
|
|
|
Self-explanatory.
|
|
|
|
E: Could not find/initialize a specified accelerator device
|
|
|
|
Could not initialize at least one of the devices specified for the gpu
|
|
package
|
|
|
|
E: Insufficient memory on accelerator
|
|
|
|
There is insufficient memory on one of the devices specified for the gpu
|
|
package
|
|
|
|
E: GPU library not compiled for this accelerator
|
|
|
|
Self-explanatory.
|
|
|
|
E: Double precision is not supported on this accelerator
|
|
|
|
Self-explanatory
|
|
|
|
E: Unable to initialize accelerator for use
|
|
|
|
There was a problem initializing an accelerator for the gpu package
|
|
|
|
E: Accelerator sharing is not currently supported on system
|
|
|
|
Multiple MPI processes cannot share the accelerator on your
|
|
system. For NVIDIA GPUs, see the nvidia-smi command to change this
|
|
setting.
|
|
|
|
E: GPU particle split must be set to 1 for this pair style.
|
|
|
|
For this pair style, you cannot run part of the force calculation on
|
|
the host. See the package command.
|
|
|
|
E: CPU neighbor lists must be used for ellipsoid/sphere mix.
|
|
|
|
When using Gay-Berne or RE-squared pair styles with both ellipsoidal and
|
|
spherical particles, the neighbor list must be built on the CPU
|
|
|
|
E: Invalid threads_per_atom specified.
|
|
|
|
For 3-body potentials on the GPU, the threads_per_atom setting cannot be
|
|
greater than 4 for NVIDIA GPUs.
|
|
|
|
E: Invalid custom OpenCL parameter string.
|
|
|
|
There are not enough or too many parameters in the custom string for package
|
|
GPU.
|
|
|
|
E: Unknown error in GPU library
|
|
|
|
Self-explanatory.
|
|
|
|
W: Increasing communication cutoff for GPU style
|
|
|
|
The pair style has increased the communication cutoff to be consistent with
|
|
the communication cutoff requirements for this pair style when run on the GPU.
