Abstract: The present disclosure provides a copper-phosphorus brazing foil and a preparation method thereof, which relates to the technical field of brazing material. It comprises a copper inner core and a copper-phosphorus alloy layer coating outside the copper inner core, wherein the phosphorus content in the copper-phosphorus brazing foil is over 5 wt %, and the thickness of the copper-phosphorus brazing foil is below 0.5 mm. In the present disclosure, red copper foil is used as the core layer, and the surface of the red copper foil is alloyed with a layer of copper-phosphorus alloy by the eutectic reaction between the core layer and red phosphorus, such that the copper-phosphorus brazing foil is obtained. The present disclosure prepares a copper-phosphorus brazing foil with high phosphorus content and lower thickness. Comparing with the traditional preparation method, the preparation method of the present disclosure has high efficiency and high yield.

Abstract: In an approach a computer receives a first request from a metadata service to store metadata for a virtual machine (VM). The computer validates the metadata service. The computer stores the metadata for the VM in response to the validation being successful. The computer receives a second request from the VM for the metadata. The computer sends the metadata to the VM.

Abstract: A wristband pulse diagnosis instrument including two pulse diagnosis instrument units is provided. Each of the two pulse diagnosis instrument units includes a wristband body, a pressure sensor, a first adjusting mechanism, and a second adjusting mechanism. A connecting member is disposed at each of two sides of the wristband body, and the connecting members are used to selectively connect the two pulse diagnosis instrument units to each other. The pressure sensor is movably disposed on the wristband body via the first adjusting mechanism and the second adjusting mechanism. A depthwise movement of the pressure sensor is adjusted by the first adjusting mechanism for the pressure sensor to move to three pulse positions of floating, medium, and deep, and a lateral movement of the pressure sensor is adjusted by the second adjusting mechanism for the pressure sensor to move to three pulse positions of distal, mid, and proximal.

Abstract: A method, computer program product, and system includes a processing circuit(s) allocating a page of system memory address space to a device. The allocating includes the processing circuits(s) obtaining base address registers of the device in a bus and determining a portion of the page of the system memory address space to allocate to the base address registers. The processing circuits(s) sorts the base address registers, in a descending order, according to their alignments and adds sizes of the sorted base address registers to determine the portion of the page. The processing circuit(s) determines a remainder of the page: a difference between a size of the page and the portion of the page. The processing circuit(s) requests a virtual resource of a size equal to the remainder and allocates the page to the sorted base address registers and to the virtual resource.

Abstract: A method, computer system, and a computer program product for a debugger with a hardware transactional memory is provided. A transaction is created to issue at least one request for accessing a memory location of a hardware transactional memory. A message is received from the hardware transactional memory indicating a conflict of access that is generated in response to the memory location being accessed by a program debugged by the debugger. In response to receiving the message from the hardware transactional memory, information associated with the conflict of access is collected to report the conflict of access.

Abstract: Embodiments of the present invention disclose a method, computer program product, and system for allocating memory. A computer receives a request for memory to be allocated to a computer node and determines if the allocation request needs to be carried out on a cluster level, a server rack level, or on a server level. The computer retrieves a memory policy associated with the determined level the allocation request needs to be carried out on from a memory policy database and determines how much available memory may be allocated and if there enough available memory to meet the request. The computer reallocates the available memory to address the received the received request based on the retrieved memory policy.
