Could you please decrease the computation size of "Gamma-ray pulsar binary search #1 1.05 (FGRPSSE)"?

It always takes me about 48 hours to finish one task (CPU: i3-3100M) :(

So is it possible for you to decrease the computation size of each task?

Thanks a lot!

The tasks are designed to

The tasks are designed to take approximately 8 hours on a recent CPU. If they take much longer than that in your case you might try to check if the CPU is not over-committed or downclocking because it gets too hot. You can usually speed up the computation a bit if you disable Hyper Threading (I didn't check if this CPU is HT capable).

The CPU is a two-core HT-capable Ivy Bridge. so reasonably modern.  As it is reported as 4 CPU the HT is probably enabled.

Another approach to reducing loading, which may be a good idea as the M in the model name hints this is a laptop, which often are not really thermally engineered to behave well at 100% CPU loading for extended periods, is to use the Computing preferences entry "Use at most   nn  % of the processors" configuration item to reduce the number of these tasks running--preferable to one.  That will show you what your machine is capable of.  And your personal use would still benefit from the latency reduction HT provides.

As well as HT being enabled,

As well as HT being enabled, both the internal GPU and an NVIDIA GPU are being used for crunching.  Apart from the heat produced, the crunch times of all task types are probably being adversely affected by this type of mix and the likely overloading it would cause.  The user should do some experimenting to find a satisfactory combination that the machine can cope with.
