    摘要: A method, system, and computer program product in a logical partitioned data processing system are disclosed for providing a host bridge that implements extended error handling (EEH). If all devices coupled to the host bridge implement EEH, the host bridge is initialized to operate in EEH mode. In EEH mode, the devices handle any error that occurs within the devices without reporting the error to the host bridge. All partitions that share the host bridge continue to operate without being terminated while the devices are handling the error. If at least one device does not implement EEH, the host bridge is initialized to operate in non-EEH mode. In non-EEH mode, a machine check is generated by the host bridge when an error occurs within one of the devices resulting in the termination of all partitions that share the host bridge in response to a receipt of the machine check.

    摘要: The invention is directed to processes for constructing DNA Libraries in which ssDNA containing a chemical modification (CM) at or near the 5′- or 3′-terminus is prepared from a RNA or DNA source, a 1st universal oligonucleotide (Oligo A′) is ligated to the 3′-of the ssDNA, and a 2nd universal oligonucleotide (Oligo B) is ligated to the 5′-terminus of the ssDNA. Chemical modifications useful for the process are functional groups capable of binding a solid support with high affinity, or functional groups that can mediate a non-enzymatic ligation. In one embodiment of the invention, a CM at or near the 5′-terminus of the ssDNA mediates binding of the ssDNA to a solid support, allowing removal of residual unligated Oligo A′ prior to ligation of Oligo B. In another embodiment of the invention, a CM at or near the 5′-terminus of ssDNA mediates non-enzymatic ligation of Oligo B to the 5′-terminus of ssDNA, under conditions in which no further ligation of Oligo A′ can occur. Libraries prepared by the method of the invention can be directly amplified by PCR or other methods. Amplified libraries, derived from minute quantities of RNA and DNA, can be used in gene expression studies, analysis of DNA polymorphisms, and high throughput sequencing. Methods of attaching the finished DNA Libraries to a solid supports for archiving are also disclosed. The invention further provides kits for carrying out the processes of the invention.
