What estimate do you give?

1. AAbout 20 hours, counting $2ND$ FLOPs for the forward pass at 40% MFU.
2. BAbout 59 hours, counting $6ND$ FLOPs for forward and backward at 40% MFU.
3. CAbout 24 hours, counting $6ND$ FLOPs and assuming the GPUs run at peak.
4. DAbout 118 hours, counting $6ND$ FLOPs at the 495 TFLOP/s TF32 peak.
