Something really handy

mpi2-report.tex -- The MPI Specifications.

I just finished modifying my prime number finder (one that's implemented on a beowulf cluster at the advanced science and technology institute (ASTI)) which also happens to yield mind boggling results.

with the previous runs i have done, i get times of around 190+ seconds, finding all the prime numbers from 1 to 999999. and that was already surprising, considering that if you run it on one computer, it's really going to take more time than that. but with the modifications in, finding all the primes from 1 to 999999 only took about 5 seconds!! that was using just 5 nodes, and a chunk size of 10000 -- this may be confirmed, and test results as soon as available may be obtained by request via email. now i have to find a setup where the cluster is really homogeneous, and where the loads of the nodes are unstable (or where the nodes are not dedicated for the cluster).

anyway, more news to come as my sem draws to a close. i might be blogging more often to let people into my life as i rest. :) keep chillin'... :D

From FOMO to JOMO

Until very recently I believed that I needed to be on top of the latest news and happenings not only in my field (computer science and software engineering) but also in as many things as I can be on top of. This meant subscribing to all sorts of magazines, newsletters, YouTube channels, Twitch streamers, watching TV and live sport events, etc. — I was on top of a lot of the latest happenings, trends, news, interesting developments. I was having fun and I felt busy. What I did not feel was particularly effective nor productive. I felt like I was consuming so much information with the thought that it might be useful someday. When I was younger this wouldn’t have been an issue but I realised that ever since I’ve started taking stock of what I’ve been spending my time on, that a lot of it I’ve been spending just staying on top of things that I really didn’t need to be on top of. This article is about some of the realisations I’ve made in the course of exploring this issue of “FOMO” or ...

Reconnecting with people

2021 started with a a good sense of connection for me, having spent time with friends and family in a simple celebration of the oncoming year. The transition from 2020 to 2021 and being able to look back at a good part of my recent history got me thinking about how life has been for me and the family for the past decade. There’ve been a lot of people that I’ve met and become friends with while there are those that I’ve left behind and lost touch with. There’s a saying about treating old friends different from new ones, which I do appreciate now that I’m a bit older. It also means that my relationships with people that I get to spend a good amount of time with take a different shape. This reflection has given me some time and space to think about what it means to reconnect with people. Friends are the family we choose ourselves. — Edna Buchman I have the privilege of having life-long friends that I don’t always stay in regular contact with. From my perspective, if I consider you a frien...

Keeping a work log

I have been keeping a journal for my personal life with some regularity for the good part of 4 years. The difference between my earlier attempts at journaling before four years ago is the regularity and the structure. I started with a very structured and regimented journal (doing it everyday with prompts and blanks to fill), to a ruled journal notebook, then a plain notebook (no rules nor grids in the pages), and then settling on a dot-grid notebook. This allows me to doodle and write free-form to help me commit thoughts and observations of my day but it was mostly for archival and looking back to "feel good" or reminisce (also to sum up a month, a year, etc.) The approach helps a lot with self-improvement in terms of my mental health and my reflection to see where I was a specific amount of time ago and whenever I was reading it again. In a previous post I wrote about keeping a work log, and I realised I only mentioned that in passing. In this post I detail the structure of ...
