Pathways Language Model (PaLM): Scaling to 540 Billion Parameters for Breakthrough Performance

Google AI introduced the 540 billion parameter Pathways Language Model. Trained on two Cloud #TPU v4 pods, it achieves state-of-the-art performance on benchmarks and shows exciting capabilities like mathematical reasoning, code writing, and even explaining jokes. https://goo.gle/3j6eMnK

PaLM demonstrates the scaling capability of the Pathways system to thousands of accelerator chips across two TPU v4 Pods by training a 540-billion parameter model efficiently with a well-studied, well-established recipe of a dense decoder-only Transformer model. Pushing the limits of model scale enables breakthrough few-shot performance of PaLM across a variety of natural language processing, reasoning, and code tasks.

PaLM paves the way for even more capable models by combining the scaling capabilities with novel architectural choices and training schemes, and brings us closer to the Pathways vision:

<<Enable a single AI system to generalize across thousands or millions of tasks, to understand different types of data, and to do so with remarkable efficiency.>>

Repair slave in MySQL GTID replication, after fatal error 1236

For repairing a broken slave after fatal error 1236.

Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'The slave is connecting using CHANGE MASTER TO MASTER_AUTO_POSITION = 1, but the master has purged binary logs containing GTIDs that the slave requires.'


slave# reset master;

slave# source /pathto/dump.sql;

slave# start slave for channel 'mymaster';

slave# show slave status for channel 'mymaster'\G


Here is another useful tutorial, if the problem persists

Repair slave in MySQL GTID replication

Run these commands on MySQL shell, to find "where" replication failed and was broken.

Stop the slave.
SET GTID_NEXT="AUTOMATIC";
stop slave;

Find the point where replication broke.
show slave status\G;

Now find "Executed_Gtid_Set". Example value:
Executed_Gtid_Set: 44d966cc-d84d-11e8-be8d-20677cd3f384:1-2872

Increase of one step to 2873
SET GTID_NEXT="44d966cc-d84d-11e8-be8d-20677cd3f384:2873";

Now start the slave.
start slave;
show slave status\G;


Here is another useful tutorial, if the problem persists

Continue the loop until no error occurs. Enjoy
