We need a way to produce realy compacted bit encodings that
can be compressed into variables, or bit arrays.
Eg. we need a way to read/write single bits from/to a holder variable, like
a one byte variable like bool char or __int8.
A 1 byte variable like bool, contains 8 bits, where only one would suffice.
This way 8 booleans could be compressed into one bolean type variable.
That is; people who striclty use boolean encodings could have their solutions run 8 times faster, and take 8 times less memory, probably increasing the benefit of shared memory substantialy.
Similarly an 8 bit int which contain 8 bits, could descripe 4 2 bit numbers
But since Cuda does not support Bit Fields, what is a good way of acheiving this ??,
I know Simon Greens image proccessing example puts 4 8 bit int’s into one 32 bit float.
But I need to put 1 boolean, 1 3 bit int, and one 4 bit int, into a 8 bit container (like bool or __int8 or whatever is the best…)
Dear Cuda Gurus, does there exist a good solution for this ?
Is there bit array support in Cuda ??
