[Quantlib-users] Question about changing ql.Settings.instance().evaluationDate in class Setting asynchronuously

[Zebang Ni <zeb...@da...>]

Hi,

Does anyone experience using ql.Settings.instance().evaluationDate
asynchronously?

I tried the calculation option Greek theta by changing a small increment on
time variable, which is ql.Settings.instance().evaluationDate here on
ql.DividendVanillaOption.

It is easy when we do everything one by one. But we are experiencing a
large amount of calculation which requires us to run the calculation
asynchronously. So I need to change ql.Settings.instance().evaluationDate
for each calculation.

Is there a way I can overwrite this setting parameters for each option
object?

Thanks,

Zebang
