Mr. Trump, the Republican presidential front-runner, was responding to a question about a bill that North Carolina’s governor signed into law last month that bars individuals in the state from using public bathrooms that do not correspond to their biological sex — the one listed on their birth certificate. Since then, there has been a backlash that has included denunciations from businesses and celebrities opposed to the state’s action. And transgender issues more generally have pitted social conservatives against business interests that traditionally have been part of the Republican coalition in the South and elsewhere.

“North Carolina did something — it was very strong — and they’re paying a big price,” Mr. Trump said. “And there’s a lot of problems. And I heard — one of the best answers I heard was from a commentator yesterday saying, leave it the way it is, right now.”

He added that before the law passed, there had been “very few problems” but now North Carolina is experiencing an exodus of businesses and “strife” from people on both sides of the issue.

“You leave it the way it is,” he said. “There have been very few complaints the way it is.”

North Carolina’s law, which also removed anti-discrimination protections for lesbian, gay, bisexual and transgender people, and the backlash to it are now at the heart of the state’s hotly contested governor’s race.

Asked if the Trump organization employs any transgender people, Mr. Trump said he truly did not know, but added, “I probably do.” And in response to a follow-up question, he said that if Caitlyn Jenner were to walk into Trump Tower and want to use a bathroom, he would be comfortable with her choosing any bathroom she wanted. “That is correct,” Mr. Trump said.

“There’s a big move to create new bathrooms” for transgender people alone, Mr. Trump said. “First of all, I think that would be discriminatory in a certain way. It would be unbelievably expensive for businesses and for the country. Leave it the way it is.”

“TPUs deliver an order of magnitude higher performance per watt than all commercially available GPUs and FPGA,” said Google CEO Sundar Pichai during the company’s I/O developer conference on Wednesday.

TPUs have been a closely guarded secret of Google, but Pichai said the chips powered the AlphaGo computer that beat Lee Sedol, the world champion in the incredibly complicated game called Go.

Pichai didn’t go into details of the Tensor Processing Unit but the company did disclose a little more information in a blog posted on the same day as Pichai’s revelation.

“We’ve been running TPUs inside our data centers for more than a year, and have found them to deliver an order of magnitude better-optimized performance per watt for machine learning. This is roughly equivalent to fast-forwarding technology about seven years into the future (three generations of Moore’s Law),” the blog said. “TPU is tailored to machine learning applications, allowing the chip to be more tolerant of reduced computational precision, which means it requires fewer transistors per operation. Because of this, we can squeeze more operations per second into the silicon, use more sophisticated and powerful machine learning models, and apply these models more quickly, so users get more intelligent results more rapidly.”

The tiny TPU can fit into a hard drive slot within the data center rack and has already been powering RankBrain and Street View, the blog said.
