8745ba1e	2012-08-15T09:38:45	Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this. Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.
9c648c17	2012-07-11T20:10:52	Bugfix: Calculate nsec in nmsleep correctly The old algorithm (msecs * 1000000) - (sec / 1000000000) gets total nsec, including seconds, since the sec/1e9 should be multiplying. It's also vulnerable to easy overflows. Using ldiv gets the quotient and remainder in a single operation (at least on x86) and avoids overflow.

c5a21fab	2012-06-23T23:43:22	Extend nrolltime to support the expiry= parameter. Do this by turning the rolltime bool into an integer set to the expiry time. If the pool supports rolltime but not expiry= then set the expiry time to the standard scantime.

Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this. Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.

Bugfix: Calculate nsec in nmsleep correctly The old algorithm (msecs * 1000000) - (sec / 1000000000) gets total nsec, including seconds, since the sec/1e9 should be multiplying. It's also vulnerable to easy overflows. Using ldiv gets the quotient and remainder in a single operation (at least on x86) and avoids overflow.

Extend nrolltime to support the expiry= parameter. Do this by turning the rolltime bool into an integer set to the expiry time. If the pool supports rolltime but not expiry= then set the expiry time to the standard scantime.
