memoryBarrierShared — controls the ordering of operations on shared variables issued by a single shader invocation
void memoryBarrierShared(
|
void); |
memoryBarrierShared waits on the completion of all memory accesses resulting
from the use of shared variables and then returns with no other effect. When this function returns, the
results of any modifications to the content of shared variables will be visible
to any access to the same buffer from other shader invocations. In particular,
any modifications made in one shader stage are guaranteed to be visible to accesses
performed by shader invocations in subsequent stages when those invocations were triggered by the
execution of the original shader invocation (e.g., fragment shader invocations for a primitive resulting
from a particular geometry shader invocation).
memoryBarrierShared is available only in the compute language.
